Purpose of debug class and limits in pipelinesession

Hi
What is the purpose of debug class(com.bea.p13n.util.debug.Debug)? I found
it in an InputProcessor. Also I am unable to find the javadocs for it.
My next question may seem trivial, but is there any limitation to the number
of attributes that can be set in the pipelinesession object or something like
that?
Thanks,
Raghu

Hi Raghu,
I think those are internal java classes used by the portal server. To your next
question, i am not aware of any limitation on the number of pipeline attributes.

Debugging Classes and methods in a Function Module

Folks
While debugging a Function Module, I want to know which classes and methods are being called as part of this FM and want to put a breakpoint in this Class method and check the details of variables in this methods. How do I accomplish this ?
Is the hierarchy that - FM will have classes which will have methods or is it something different ?
Thanks

Goto SE24->Give class name as CL_EXITHANDLER->Display->double click on get_instance mathod->Now u will go inside the method->Now put break point on the cl_exithandler.Now go to any transaction code ( se37) and pass dat..U will see that it will be stopped on the break point which u set on the cl_exithandler...
than can debug further.

Hi Blake
SAP R/3 Correction and Transport System
Operating system level files in the transport process:
The SAP C program TP, requires a special file structure for the transport process. The file system is operating system dependent. TP uses a transport directory or file system, which is called /usr/sap/trans.
The /usr/sap/trans file system is generally NFS mounted form the development system to other systems unless a system is defined as a single system in the CTS pipeline. All the sub directories should have <SID>adm as the owner and sapsys as the group; and proper read, write and execute access should be given to owner and the group. The TP imports are always performed by <SID>adm.
The following are the subdirectories in /usr/sap/trans:
/data
/cofiles
/bin
/log
/actlog
/buffer
/sapnames
/tmp
/usr/sap/trans/data: holds the data of transport objects after they are released . The example of a data file is R904073.DEV. The extension DEV means the data file was released from the DEV or development system.
/usr/sap/trans/cofiles: The cofiles directory holds the command files for all change requests. These files are like a command or control files used to import the data files. The common directory for CTS system is /usr/sap/trans. After a change request is released from the source system , the data is exported immediately to the file system of the operating system. The SAP transport utility TP uses the cofile to transport a data file. The example of a file in cofiles directory is K904073.DEV.
/usr/sap/trans/bin: holds the most important file TPPARAM in the CTS system. TPPARAM file has all the information about the CTS systems in the CTS pipeline. TPPARAM file is the parameter file for the transport program TP and it is the common file for all the systems in the CTS pipeline. As you know already that /usr/sap/trans should be NFS mounted to all the systems in a CTS pipeline, TP program has access to the TPPARAM file from all the systems. The following is an example of typical TPPARAM file for five SAP systems in the CTS pipeline:
#@(#) TPPARAM.sap 20.6 SAP 95/03/28

First we specify global values for some parameters, #

DEV/dbhost = sap9f
DEV/r3transpath = /usr/sap/DEV/SYS/exe/run/R3trans
QAS/dbname = QAS
QAS/dbhost = sap8f
QAS/r3transpath = /usr/sap/QAS/SYS/exe/run/R3trans
TRN/dbname = TRN
TRN/dbhost = sap17
TRN/r3transpath = /usr/sap/TRN/SYS/exe/run/R3trans
PRE/dbname = PRE
PRE/dbhost = sap19f
PRE/r3transpath = /usr/sap/PRE/SYS/exe/run/R3trans
PRD/dbname = PRD
PRD/dbhost = sap18f
PRD/r3transpath = /usr/sap/PRD/SYS/exe/run/R3trans
/usr/sap/trans/log: holds the entire log files, trace files and statistics for the CTS system. When the user goes to SE09 (workbench organizer) or SE10 (customizing organizer) transaction and opens the log for a transport, the log file for that transport will be read from /usr/sap/trans/log directory. Each change request should have a log file. Examples of log files are DEVG904073.QAS, DEVI904073.QAS and DEVV904073.QAS. The name of a log file consists of the names of the change request, the executed step, and the system in which the step was executed:
<source system><action><6 digits>.<target system>
Now we can analyze the above example DEVG904073. QAS. The <source system> = DEV, <action> = G or report and screen generation, <6 digits> = 904073 (these six digits numbers are exactly the same number as the six digits of the transport) and the <target system> = QAS
Possible values for <action> are:
A: Dictionary activation
D: Import of application-defined objects
E: R3trans export
G: Report and screen generation
H: R3trans dictionary import
I: R3trans main import
L: R3trans import of the command files
M: Activation of the enqueue modules
P: Test import
R: Execution of reports after put (XPRA)
T: R3trans import of table entries
V: Set version flag
X: Export of application-defined objects.
/usr/sap/trans/actlog: holds action log files. The example of an action file is DEVZ902690.DEV. The following are the contents of the file:

/usr/sap/trans/buffer: transport buffer of the target systems; contains control information on which requests are to be imported into which systems and in what order the imports must occur. The /usr/sap/trans/buffer will have a directory for each system in the CTS pipeline. For example the buffer file for DEV system is /usr/sap/trans/buffer/DEV.
/usr/sap/trans/sapnames: holds information pertaining to transport requests for each system user. There are files for each user who released change requests from the system.
/usr/sap/trans/tmp: holds information about temporary data and log files. While the transport is occurring the Basis administrator can find a file that is related to the transport in the tmp directory; that file shows the exact status if the transport (What objects are being imported at that time).
Important SAP delivery class and table types and tables in the CTS process:
Delivery class
The delivery class defines who (i.e. the SAP system itself or the customer) is responsible for maintaining the table contents. In addition the delivery class controls how the table behaves in a client copy and an upgrade. For example when you select a SAP defined profiles to perform a client copy, certain tables are selected according to their delivery class. DD02L table can show what delevery class a table belongs to.
The following delivery classes exist:
A: Application table.
C: Customizing table, maintenance by customer only.
L: Table for storing temporary data.
G: Customizing table, entries protected against overwriting.
E: Control table.
S: System table, maintenance only by SAP.
W: System table, contents can be transported via own TR objects.
Table type
The table type defines whether a physical table exists for the logical table description defined in the ABAP/4 Dictionary and how the table is stored on the database.
The following are different table types in SAP:
Transparent Tables
There is a physical table on the database for each transparent table. The names of the physical table and the logical table definition in the ABAP/4 Dictionary are same. For every transparent table in SAP, there is a table in database. The business and application data are stored in transparent tables.
Structure
No data records exist on the database for a structure. Structures are used for the interface definition between programs or between screens and programs.
Append Structure
An Append structure defines a subset of fields which belong to another table or structure but which are treated as a separate object in the correction management. Append structures are used to support modifications.
The following table types are used for internal purposes, for example to store control data or for continuous texts:
Pooled table
Pooled tables can be used to store control data (e.g. screen sequences, program parameters or temporary data). Several pooled tables can be combined to form a table pool. The table pool corresponds to a physical table on the database in which all the records of the allocated-pooled tables are stored.
Cluster table
Cluster tables contain continuous text, for example documentation. Several cluster tables can be combined to form a table cluster. Several logical lines of different tables are combined to form a physical record in this table type. This permits object-by-object storage or object-by-object access. In order to combine tables in clusters, at least part of the keys must agree. Several cluster tables are stored in one corresponding table on the database.
Tables in CTS process:
TRBAT and TRJOB:
TRJOB and TRBAT are the major tables in the CTS process. After TP program has sent the event to the r3 system, RDDIMPDP checks table TRBAT in the target system to find out if there is an action to be performed. Mass activation, distribution, or table conversions are the examples of actions. If there is action to be performed, RDDIMPDP starts the appropriate program in the background task. RDDIMPDP then reschedules itself.
By checking table TRJOB, RDDIMPDP automatically recognizes if a previous step was aborted, and restarts this step. For each transport request , TP program inserts an entry into table TRBAT. If the return code 9999 in this table then the step is waiting to be performed. Return code 8888 indicates that the step is active and currently being processed. A return code of 12 or less indicates that the step is finished. In addition, TP inserts a header entry to let the RDDIMPDP program know to start processing. The column return code will therefore contain a B for begin. When RDDIMPDP is started, it sets the header entry to R(un), and starts the required program. When all the necessary actions are performed for all the transport requests, the column return code contains all the return codes received, and the column TIMESTAMP contains the finishing time. The header entry is set to F(inished). TP monitors the entries in TRBAT and TRJOB tables. When the header entry in TRBAT is set to finished. The entry in TRJOB is deleted.
Transport Tables SE06
TDEVC - Development classes
TASYS - Details of the delivery. Systems in the group that should automatically receive requests, have to be specified in table TASYS.
TSYST - The transport layers will be assigned to the integration systems. ( Define all systems)
TWSYS - Consolidation routes ( define consolidation path)
DEVL - Transport layers are defined here
In u201CConfiguring the CTS systemu201D section, We will learn more about the transport tables in SE06 transaction
Programs in the CTS process:
In the CTS table section we learned about the RDDIMPDP program. RDDIMPDP program needs to be scheduled in all the clients in an instance. It is recommended to schedule the RDDIMPDP as event driven.
RDDPUTPP and RDDNEWPP programs can be used to schedule RDDIMPDP program in the background.
The ABAP/4 programs that RDDIMPDP starts are determined by the transport step to be executed that is entered in the function field of table TRBAT.
Function Job Name Description of transport Steps
J RDDMASGL Activation of ABAP/4 dictionary objects
M RDDMASGL Activation of match codes and lock objects
S RDDDISOL Analysis of database objects to be converted
N RDDGENOL Conversion of database objects

Version Management:
One of the important features of Workbench Organizer is Version Management. This feature works for all the development objects. Using the version management feature the users can compare and retrieve previous versions of objects.
Version management provides for comparisons, restore of previous versions, documentation of changes and assistance in the adjustment of data after upgrading to a new release. With the release of a change request, version maintenance is automatically recorded for each object. If an object in the system has been changed N times, it will have N delta versions and one active version. To display version management, for ABAPs use transaction SE38 and for tables, domains and data elements use SE11. The path to follow is Utilities -> Display version. Using version management the users can view existing version for previously created ABAP code, make changes to the code, compare code versions and restore original version of the code. Now the users will be restore previous versions without cut and paste steps of the past.
TP and R3trans program:
The basis administrator uses TP program to transport SAP objects from one system to another. TP is a C program delivered by SAP that runs independently of the R/3 system. TP program uses the appropriate files located in a common transport directory /usr/sap/trans. TP starts C programs, ABAP/4 programs and special operating system commands to its job. R3trans is one of the most important utility program called by TP. Before using the TP program, the basis administrator needs to make sure that the CTS system is setup properly and the right version of TP is running in the system. The TP program is located in the run time directory /usr/sap/<SID>/SYS/exe/run directory. It is automatically copied in the install process. A global parameter file TPPARAM that contains the databases of the different target systems and other information for the transport process controls TP. The global parameter file determines which R3trans is used for each system. If the parameter r3transpath is not defined properly then no export and import can be done. The basis administrator should make sure that the default value u201Cr3transpathu201D is properly defined. Later in this chapter we will learn more about TP and R3trans; also we are going to see how they are used.
Configuring the TPPARAM file:
Each time TP is started, it must know the location of the global parameter file. As we have seen before TPPARAM file should be in directory /usr/sap/trans/bin. The parameters in TPPARAM can either global (valid for each and every system in the cts pipeline) or local to one system. Th parameters are either operating system dependant (these parameters preceded by a keyword corresponding to the specific operating system) or database dependant (contain a keyword corresponding to a specific database system).
The global parameter file provides variables that can be used for defining parameters. The variables can be defined in format: $(xyz). The brackets can be substituted with the u201C\u201D-character if required.
The following pre-defined variables are available for the global parameter file:
$(cpu1): The CPU name can be sun or as4 for example. In heterogeneous networks this variable is very important.
$(cpu2): Acronym for the name of the operating system. The example for this variable can be
hp-ux, or sunos . This is an operating system specific variable.
$(dname): Used for the day of the week (SUN,MON,u2026.).
$(mday): Used for the day of the current month (01-31).
$(mname): Used for the name of the month (JANu2026DEC).
$(mon): Used for the Month (01-12).
$(system): R/3 System name.
$(wday): Day of the week (00-06, Sunday=00, Monday=01, Tuesday=02 and so on).
$(yday): Day of the current year (001-366). Using the number any day of the year can be chosen.
$(year): Year (Example:1998 or 1999).
$(syear): Short form of the year (two positions).
$(yweek): Calendar week (00-53). The first week begins with the first Sunday of the year.
For the database connection:
The transport environment also needs parameters to connect to the R/3 System database. As we know already the every instance in the R/3 CTS pipeline has its own database, therefore specific parameters should be defined for each database system. From dbtype parameter of RSPARAM file, TP program identifies the database system.
The two parameters u201Cdbnameu201D and u201Cdbhostu201D are required for ORACLE databases.
DBHOST: is the name of the computer on which the database processes execute. TCP/IP name of the host if NT is being used.
DBNAME: is the name of the database instance.
As of Release 3.0E, two new parameters have been introduced.
DBLOGICALNAME: The default value is $(system). The logical name that was used to install the database.
DBCONFPATH: The default value is $(transdir).
The parameters u201Cdbnameu201D and u201Cdbhostu201D are also used for INFORMIX databases in an installation:
DBHOST: Same as Oracle.
DBNAME: Name of the database instance, uppercase and lowercase are distinguished here.
INFORMIXDIR : u201C/informix/<SAPSID>u201D is the default value. Defines the directory namewhere the database software can be found.
INFORMIXSQLHOSTS: u201C$(informixdir)/etc/sqlhosts[.tli|.soc]u201Cis default value under Unix. The name of the SQLhosts file with its complete path is defined with this parameter.
INFORMIX_SERVER: u201C$(dbhost)$(dbname)shmu201D is the default value. The name of the database server may be specified for a local connect.
INFORMIX_SERVERALIAS: u201C$(dbhost)$(dbname)tcpu201Dis the default vlue. The name of the database server can be specified for a remote connect.
For Microsoft SQL Server database the two parameters u201Cdbnameu201D and u201Cdbhostu201D are also required. DBHOST: The TCP/IP name of the host on which the database is running.
DBNAME: The database instance name.
For DB2 in AS/400 only u201Cdbhostu201D is required.
DBHOST: System name of the host on which the database is running.
If theu201DOptiConnectu201D is used, the following line should be specified:
OPTICONNECT 1
For DB2/ AIX
The two parameters u201Cdbnameu201D and u201Cdbhostu201D are required
DBHOST: The host on which the database processes are running. It is the TCP/IP name of the host for Windows NT (As we have seen in the earlier examples).
DBNAME: Database instance name.
The DB2 for AIX Client Application Enabler Software must also be installed on the host on which tp is running.
ALLLOG: u201CALOGu201D $(syear) $(yweek)u201Dis the default value. This variable can be used in TPPARAM file to specify the name of a file in which tp stores information about every transport step carried out for a change request anywhere in the transport process. The file always resides in the log directory.
SYSLOG: u201CSLOG $(syear) $(yweek).$(system)u201D is the default value. This variable can be used to name a file in which tp stores information about the progress of import actions in a certain R/3 System. The file does not store information for any particular change request. The file always resides in the log directory.
tp_VERSION: Zero is the default value. If this parameter is set to not equal to zero, a lower version of tp may not work with this TPPARAM file. If the default value (zero) is set, the parameter has no affect.
STOPONERROR: (Numeric value) The default value is 9. When STOPONERROR is set to zero, tp is never stopped in the middle of an u201Cimportu201D or u201Cputu201D call. When STOPONERROR is set to a value greater than zero, tp stops as soon as a change request generates a return code that is equal to or greater than this value (The numeric value of the STOPONERROR parameter is stored in the variable BADRC). Change requests, which still have to be processed for the current step, are first completed. A u201CSYNCMARKu201D in the buffer of the R/3 System involved, sets a limit here. tp divides the value of this parameter between two internal variables. STOPONERROR itself is treated as a boolean variable that determines whether tp should be stopped, if the return code is too high.
REPEATONERROR (Numeric value too): The default value is 9. The REPEATONERROR parameter is similar to STOPONERROR. The difference is, REPEATONERROR specifies the return code up to which a change request is considered to be successfully processed. Return codes less than REPEATONERROR are accepted as u201Cin Orderu201D. Change requests that were not processed successfully stay in the buffer.
NEW_SAPNAMES: Default value is u201CFALSEu201D. A file is created for each user of the R/3 System group in the u201Csapnamesu201D subdirectory of the transport directory. Except some of the operating system,the name of the user is the name of the file. It is very important to remember hat the special characters or length of the file name could cause problems. If all the R/3 Systems in the transport group have at least Release level 3.0.; TP program is efficient to handle this problem. The user names are modified to create file names that are valid in all operating systems and the real user names are stored in a corresponding file.
Though we have seen so many parameters, for the minimum configuration the following two parameters are very important.
TRANSDIR: specifies the name of the common transport directory. The following is a typical example from TPPARAM of Unix as we have seen before.
transdir = /usr/sap/trans/
DBHOST: contains the name of the database host. In Windows NT environment, this is the TCP/IP host name. The following is an example in Unix:
DEV/dbname = DEV
DEV/dbhost = sap9f
DEV/r3transpath = /usr/sap/DEV/SYS/exe/run/R3trans
For TP, to control u2018Start and Stopu2019 command files and database in R/3 the following important parameters are specified in TPPARAM:
Parameters for the tp Function u201CPUTu201D: LOCK_EU (boolean) default value is u201CTRUEu201D. Though from version 3.1 onward the tp put command is used seldom in cts process still it is important to know how this parameter works. When u201Ctp putu201D is used, it changes the system change option . If the parameter is set to u201CFALSEu201D nothing gets changed. If the parameter is set to u201CTRUEu201D, the system change option is set to u201CObjects cannot be changedu201D at the beginning of the call, and gets changed back to its previous value at the end of the call. The u201Ctp putu201D command will give the exact status of the locking mechanism.
LOCKUSER (used as boolean value): Default value is u201CTRUEu201D. This parameter is about the user login while tp put call is executed. If this parameter is set to u201CFALSEu201D, no locking mechanism for the users takes affect. If this parameter is defined as u201CTRUEu201D then a character is set in the database level; so only DDIC and SAP* can log on to the system. Users that have already logged on are not affected (this is a reason for activating the parameters STARTSAP and STOPSAP). The charactertor is removed at the end of the call, and all the users can log on to the SAP R/3 System again.
STARTSAP: Default value is u201D u201C.or u201CPROMPTu201D for Windows NT . This parameter is used by TP to start an R/3 System. It is not necessary for the clients to make tp start and stop R/3 system..
STOPSAP: Default value is u201D u201Cor u201CPROMPTu201D for Windows NT. TP uses this parameter to stop an R/3 System.
STARTDB: Default value is u201D u201C. TP uses the value of this parameter to start the database of an R/3 System.
The parameter is not active under Windows NT.
STOPDB: Default value is u201D u201C. TP uses the value of this parameter to stop the database of an R/3 System.
This parameter is not active under Windows NT.
The above parameters in UNIX can be used as following:
STARTSAP = startsap R3
STOPSAP = stopsap R3
STARTDB = startsap db
STOPDB = stopsap db
In Windows NT:
STARTSAP =
$(SAPGLOBALHOST)\sapmnt\$(system)\sys\exe\run\startsap.exe
R3 <SID> <HOST NAME> <START PROFILE>
STOPSAP =
$(SAPGLOBALHOST)\sapmnt\$(system)\sys\exe\run\stopsap.exe
R3 <SID> <HOST NAME> <INSTANCE> <PROFILE PATH + Instance profile>
The parameters STARTDB and STOPDB are not active under Windows NT.
Parameters for the tp function u201CCLEAROLDu201D
DATALIFETIME (Numeric): Default value is u201C200u2033. When the data file has reached a minimum age, it is moved to the subdirectory old data with tp check. tp clearold all. The life span of the data files in the data sub directory can be set in days with this all, parameter.
OLDDATALIFETIME (Numeric): Default value is u201C365u2033. When a file located in the olddata subdirectory is no longer needed for further actions of the transport system and has reached a minimum age, it is removed with tp check.all, tp clearold all. The minimum age in days can be set with this parameter.
COFILELIFETIME (Numeric): Default value is u201C365u2033. This parameter is used just like DATALIFETIME parameter.
LOGLIFETIME (Numeric): Default value is u201C200u2033. This parameter applies to the life span of the log files. When the log files in log subdirectory is no longer needed for the transport system and has reached a minimum age, it is deleted with the calls tp check.all, tp clearold all. The minimum age in days can be defined with this parameter.
The Three Key Utilities of the CTS system (TP, R3trans and R3chop):
TP: Earlier in this chapter we have seen the objectives of TP. The TP transport control program is a utility program that helps the user to transport objects from one system to another. TP program is the front-end for the utility R3trans. TP stands for u201CTransports and Putsu201D. To make the TP work successfully the CTS system needs to be correctly configured. The following steps are very important for TP to run properly.
The transport directory /usr/sap/trans must be installed and NFS mounted to all the systems in the CTS pipe line.
RDDIMPDP program must be running (event driven is recommended) in each client. RDDIMPDP can be scheduled in the background by executing RDDNEWPP or RDDPUTPP. Use the tp checkimpdp <sap sid> command in /usr/sap/trans/bin directory as <sid>adm user to check RDDIMPDP program.
Use the tp connect <sap sid> command in /usr/sap/trans/bin directory to see whether the tp program is connecting to the database successfully or not. To run TP command the user has to logon as <sid>adm in source or target system.
The R/3 Systems in the CTS pipeline must have different names.
The Global CTS Parameter File TPPARAM must be correctly configured.
The source system (for the export) and target system ( for the import) must have at least two background work processes. TP always schedules the C class job, so if all the background jobs are defined as A class job then there will be problems in transport steps.
Important Tips :.It is always better to have the up to date TP version installed in your system. A user can ftp a current version of TP from SAPSERV4 of SAP. Though R3trans and other utility programs can be used to do the transport, it is recommended to use TP whenever possible for the following reasons..
The exports and imports are done separately using TP program. For example: when a transport is released from the system, the objects are exported from the source database to the operating system and then the import phase starts to transport those objects to the target system.
TP takes care of the order of the objects. The order, that was followed to export the objects; the same order will be followed to import them to the target database.
The TP command processes all change requests or transports in the SAP system buffer that have not yet been imported successfully. All the import steps are executed automatically after TP calls R3trans program to execute the following necessary steps:
Dictionary Import: ABAP/4 dictionary objects will be imported in this step.
Dictionary Activation: Name tabs or runtime descriptions will be written inactively. The R/3 system keeps running until the activation phase is complete. The enqueue modules are the exceptions in the running phase. After the activation of new dictionary structure the new actions are decided to get the runtime objects to the target system.
Structure conversion: If necessary the table structure is changed in this phase.
Move Nametabs: The new ABAP/4 Dictionary runtime objects which were inactive up to now are moved into the active runtime environment in this process. The database structures are adjusted accordingly. From the first step to the Main import step inconsistencies can occur to the R/3 system. After the main import phase all the inconsistency ca be solved.
Main import with R3trans: All the data are imported completely and the system comes to a consistent state.
Activation of enqueue-objects: The enqueue-objects cannot be activated in the same way as the objects of the ABAP/4 Dictionary, so they have to be activated after the main import in this step. They are then used directly in the running system.
Structure Conversion of match codes, Import application defined objects, versioning and execution of user defined activities are some of the steps after activation of enqueue-objects. The next step is generation of ABAP/4 programs and screens, where all the programs and screens associated with the change request are generated. When all the import steps are completed successfully, the transport request is removed from the import buffer.
It is recommended by SAP to schedule regular periods for imports into the target system (e.g. daily, weekly or monthly). Shorter periods between imports are not advisable. The transport to production should not be done in the off hours when the users are not working
TP can be started with different parameters. The u201Ctp helpu201D command can help user to generate a short description about the use of the command.
The following are the some important commands of TP:
For export:
tp export <change request>: The complete objects in the request from the source system will be transported. This command also used by SAP System when it releases a request.
tp r3e <change request>: R3trans export of one transport request.
tp sde <change request>: Application defined objects in one transport request can be exported.
tp tst <change request> <SAP system >: The test import for transport request can be done using this command.
tp createinfo <change request>: This command creates a information file that is automatically done during the export.
tp verse <request>: This command creates version creates versions of the objects in the specified request.
To Check the transport buffer, global parameter file and change requests:
tp showbuffer <sid>: Shows all the change requests ready to be imported to the target system.
tp count <sid>: Using this command users can find out the number of requests in the buffer waiting for import.
tp go <sid>: This command shows the environment variables needed for the connection to the database of the <sid> or target system.
tp showparams <sid>: All the values of modifiable tp parameters in the global parameter file. The default value is shown for parameters that have not been set explicitly.
To import the change requests or transports:
tp addtobuffer <request>.<sid>: If a change request is not in the buffer then this command is used to add it to the buffer, before the import step starts.
tp import all <sid>: This command imports all the change requests from the buffer to the target system.
tp put <sid>: The objective of this command is same as u201Ctp import all <sid>u201D, but this command locks the system. This command also starts and stops the SAP system, if the parameters startsap and stopsap parameters are not set to u201D u201C.
tp import <change request> <sid>: To import a single request from the source system to target system.
tp r3h <change request>| all <sid>: Using this command user can import the dictionary structures of one transport or all the transport from the buffer.
tp act <change request>|all <sid>: This command activates all the dictionary objects in the change request.
tp r3i <change request> | all <sid>: This command imports everything but dictionary structures of one.
tp sdi <change request>|all <sid>: Import application-defined objects.
tp gen <change request>|all <sid>: Screen and reports are generated using this command.
tp mvntabs <sid>: All inactive nametabs will be activated with this command.
tp mea <change request>|all <sid>: This command will activate the enqueue modules in the change request.
When you call this command, note the resulting changes to the import sequence.
Additional tp utility options:
tp check <sid>|all (data|cofiles|log|sapnames|verbose): User uses this command to find all the files in the transport directory that are not waiting for imports and they have exceeded the minimum time specified using the COFILELIFETIME, LOGFILELIFETIME, OLDDATALIFETIME and DATALIFETIME parameters of TPPARAM file.
tp delfrombuffer <request>.<sid>: This command removes a single change request from the buffer. In case of TMS, the request will be deleted from the import queue.
tp setstopmark <sid>: A flag is set to the list of requests ready for import into the target system. When the user uses the command tp import all <sapsid> and tp put <sapsid>, the requests in front of this mark are only processed. After all the requests in front of the mark have been imported successfully, the mark is deleted.
tp delstopmark <sid>: This command deletes the stop mark from the buffer if it exists.
tp cleanbuffer <sapsid>: Removes all the change requests from the buffer that are ready for the import into the target system.
tp locksys <sid>: This command locks the system for all the users except SAP* and DDIC. The users that have already logged on are not affected by the call.
tp unlocksys <sid>: This command unlocks the system for all the users.
tp lock_eu <sid>: This command sets the system change option to u201Csystem can not be changedu201D tmporarily.
tp unlock_eu <sid>: This command unlocks the system for all the changes.
tp backupall <sid>: This command starts a complete backup using R3trans command. It uses /usr/sap/trans/backup directory for the backup.
tp backup delta <sid>: Uses R3trans for a delta backup into /usr/sap/trans/backup directory.
tp sapstart <sid>: To start the R/3 system.
tp stopsap <sid>: To stop the R/3 system.
tp dbstart <sid>: To start the database.
tp dbstop <sid>: To stop the database.
Unconditional modes for TP: Unconditional modes are used with the TP program and these modes are intended for the special actions needed in the transport steps. Using unconditional mode user can manipulate the rules defined by the workbench organizer. The unconditional mode should be used when needed, otherwise it might create problems for the R/3 system database. Unconditional mode is used after the letter u201CUu201D in the TP command. Unconditional mode can be a digit between 0 to 9 and each has a meaning to it. The following is a example of a import having unconditional mode.
tp import devk903456 qas client100 U12468
0: Called a overtaker; change request can be imported from buffer without deleting it and then uncoditional mode 1 is used to allow another import in the correct location.
1: If U1 is used with the export then it ignores the correct status of the command file; and if it is used with import then it lets the user import the same change request again.
2: When used with tp export, it dictates the program to not to expand the selection with TRDIR brackets. If used in tp import phase, it overwrites the originals.
3: When used with tp import, it overwrites the system-dependant objects.
5: During the import to the consolidation system it permits the source systems other than the integration system.
6: When used in import phase, it helps to overwrite objects in unconfirmed repairs.
8: During import phase it ignores the limitations caused by the table classification.
9: During import it ignores that the system is locked for this kind of transport.
R3trans: TP uses R3trans program to transport data from one system to another in the CTS pipeline. efficient basis administrator can use R3trans directly to export and import data from and into any SAP systems. Using this utility transport between different database and operating system can e done without any problems. Different versions of R3trans are fully compatible with each other and can be used for export and import. The basis administrator has to be careful using R3trans for different release levels of R/3 software; logical inconsistency might occur if the up to date R3trans is not used for the current version of R/3 system.
The syntax for using the control file is following:
R3trans [<options>] <control file> (several options used at the same time; at least one option must be there)
For example: R3trans u2013u 1 u2013w test.log test
In the above example a unconditional mode is used, a log file u201Ctest.logu201D file is used to get the log result and a control file u201Ctestu201D, where the instructions are given for the R3trans to follow. The user needs to logon as <sid>adm to execute R3trans.
The following options are available for the R3trans program:
R3trans -d : This command is used to check the database connection .
R3trans -u <int>: Unconditional mode can be used as we have seen in the above example.
R3trans -v : This is used for verbose mode. It writes additional details to the log file
R3trans -i <file>: This command directly imports data from data file without a control file.
R3trans -l <file>: This provides output of a table of contents to the log file.
R3trans -n : This option provides a brief information about new features of R3trans.
R3trans u2013t: This option is used for the test mode. All modifications in the database are rolled back.
R3trans -c <f1> [<f2>]: This command is used for conversion. The <f1> file will be copied to <f2> file after executing a character set conversion to the local character set.
Important tips: Do not confuse the backup taken using R3trans with database backup. The backups taken using R3trans are logical backups of objects. In case something happens to the SAP system these backups can not be used for recovery. R3trans backups can be only used to restore a copy of a particular object that has been damaged or lost by the user.
R3trans -w <file>: As we have seen in the above example this option can be used to write to a log file. If no file is mentioned then trans.log is default directory for the log.
R3trans also can be used for the database backup.
R3trans u2013ba: This command is used for a complete backup. we will see in the next paragraph how to use
the control file for the backup.
R3trans u2013bd: This command is used for a delta backup if the user does not want a complete backup.
R3trans u2013bi: This option will display backup information.
The following are some of the examples of control files:
We have already learned how to use a command for the logical backup of the objects in the database. To get a complete backup the following example control file can be used.
backup all
file = /usr/sap/trans/backall
The option u201Cfile = u2026u201D is the name of the directory into which the data files are to be written. If you are taking a complete backup of DEV system then the backup file is going to look like u201CDEV.A000.bcku201D the next complete

Customizing FD01 and FB70 using PS Class and Characteristics

Hello SAP Experts
I have the following issue:
My client has a requirement where we need to customize the Customer Master (FD01) screen and the Invoice Posting Screen (FB70). A few additional fields have to be added by creating a separate tab. I was intending to take Abaper's help and do this using user exits but I have been suggested by the cleint to use SAP PS Class and Characteristics feature to do this. Can someone please throw some light on this feature and how can i create custom fields on FD01 and FB70 screens. Is there a way we could customize these screens using PS class and characteristics. Your opinions would be much appreciated.
Please kindly give your suggestions. Thanks in advance
Regards,
Nik

Joao Paulo,
Thank you for the response. I have tried to obtain some info from OSS but no luck. Tried all means but there is limited information available.

Purpose of Requirement Class

What is the purpose of requirement class?

The requirements class contains all control features for planning such as relevance for
planning, requirements planning strategy and requirements consumption strategy. In
addition, it is specified at a global level whether an availability check is to take place for
the material in the sales and distribution documents on the basis of the ATP quantity
(ATP = available to promise) and whether requirements are to be passed on. A finer
degree of control can be obtained for sales documents using the schedule line category.
Replenishment lead time is only included in the check performed on the basis of the
ATP quantity.

Private inner class and static private inner

Hi,
I understand the concept and usage of inner classes in general.
When should we go for a private inner class and when for a static private inner class? I tried searching but it wasn't of much help.
Basically I need to design a caching solution in which I need to timestamp the data object. After timestamping, data will be stored in a HashMap or some other collection. I'm planning to use a wrapper class (which is inner and private) which holds the data object and timestamp. I can make the program work by using either normal inner class or static inner class, however would like to know which is better in such case. Also If I can get some general guidelines as to when to use a staic inner class and when to use a normal inner class, it would help me.
Thanks in advance.

If I can get some general guidelines as to when to use a static inner class and when to use a normal inner class, it would help me.Making the inner class static is helpful in that it limits visibility.
If the inner class needs to access non-static fields or methods from the containing class instance
the inner class has to be non-static.

What are the key benefits and limitations of new pricing model of X5-2?

What are the key benefits and limitations of new pricing model that started with X5 version?

1. Elastic Configurations
Size/price hardware by the number of servers; Fixed configs no longer required
Start with 2 Database Servers and 3 Storage Servers. Incrementally add database or storage servers online.
2. Capacity-on-Demand (CoD)
Upon installation, activate 40-100% of the cores per server and reduce software licenses; Applies to Eighth Rack now too
Activate and license more cores when needed; Active cores may not be deactivated
3. OVM and Trusted Partitions
License software on Virtual CPUs within a VM; Ideal for special-purpose DB options
You can mix different combination of options for different DB on one Exadata.
OVM has no License cost; support is included with premier hardware support
Limitation:
At least 40% of usable cores on the machine must be licensed for Oracle software
Cannot use both OVM and CoD to license less than 40% of cores
A server must be virtualized or non-virtualized – not mixed
A RAC cluster can mix virtualized and non-virtualized servers
4. “Flash Drive” License Metric for EF Storage Server Software
$20K/drive; 8 flash drives/EF server vs 12 disk drives/HC server = 33% higher list
Can transfer licenses between Flash Drive (2 licenses/drive) and Disk Drive (1 license/drive) – part # is the same

Static class and clustering

          I have a static class that I use to cache some values during a batch process. The
          batch process uses a JMS queue to parcel our identical units of work to MDBs.
          I want this to scale using a cluster with the same MDBs on multiple machines.
          Everything works fine except that I can't figure out how to tell my cache to clear
          itself out on every node between batch runs. Is there a pattern or solution to
          this problem?
          What I've tried is to create a stateless session bean method that clears my cache.
          At the begining of my batch job, (which is a stateless session bean call) I call
          this method on each server in the cluster by getting the remote interface for
          the stateless bean via the different URLs of the servers. However, the session
          bean method always executes on the one server where I make the call. It's as if
          WebLogic gives me back a local interface instead of the remote interface that
          I asked for.
          Any ideas would be appreciated.
          Colin


... static class and static method.I have never heard of a thing called "static class". Perhaps you mean a class with only static members?
My design approach (which is bound to needs of the moment and seldom to library-development or future re-use, since both is harder than most developers realize) is to develop straight without caring too much about static or not. When a method is done, debugged and works well, it happens that other objects access this method as well.
It may happen that I just want to use this single method and almost nothing else of the object. If that is the case, I can start looking if it's a Good Thing(tm) to make the method static, so no object creation is needed just for the one method. Sometimes it can be done, sometimes not.
But that's just me and you'll find quite a lot of coders that'll advice you to decide what's static and what not before you start coding. And that's as good an advice as most others you can get.
In the end it's your decision, so start fiddling around and see what fits best for you.

Redeploying classes and EJBs into a running, external WeblogicServer6.1 application

Is it possible to debug, edit, compile and deploy the new class and/or EJB using
jBuilder5 on Win2k and WeblogicServer6.1 on Solaris WITHOUT restarting the app
server? Is there solid documentation, where? I can debug, but the 'documentation'
concerning re-deployment on an external WLS application server is vague at best.
For example, from Borland...."If the EJB already exists in WebLogic Server, it
may be necessary either to use re-deploy or to remove it from WebLogic Server
before deployment." From BEA, "...create an empty file named REDEPLOY in the directory
where the exploded application resides. ... After copying the new files, touch
the REDEPLOY ...."

I think i figured this one out. Thanks to everyone who looked at it. Have yourselves a good one.

Homework help--almost done but don't know how my class and main work?

hello, i'm doing a project for my intro to java class. i'm almost done but i'm very confused on making my main and class work. the counter for my class slotMachine keeps resetting after 2 increments. also i don't not know how to make my quarters in the main receive a pay out from my class. Please guide me to understand what i have to do to solve this problem...I have listed my question page and my class and main of what i have done so far. Thank you .I will really appreciate the help.
Objective: Create a class in Java, make instances of that class. Call methods that solve a particular problem Consider the difference between procedural and object-oriented programming for the same problem.
Program Purpose:
Find out how long it will take Martha to lose all of her money playing 3 instances of the slot machine class.
Specification: Martha in Vegas
Martha takes a jar of quarters to the casino with the intention of becoming rich. She plays three machines in turn. Unknown to her, the machines are entirely predictable. Each play costs one quarter. The first machine pays 30 quarters every 35th time it is played; the second machine pays 60 quarters every 100th time it is played; the third pays 11 quarters every 10th time it is played. (If she played the 3rd machine only she would be a winner.)
Your program should take as input the number of quarters in Martha's jar (there will be at least one and fewer than 1000), and the number of times each machine has been played since it last paid.
Your program should output the number of times Martha plays until she goes broke.
Sample Session. User input is in italics
How many quarters does Martha have in the jar?
48
How many times has the first machine been played since playing out?
30
How many times has the second machine been played since paying out?
10
How many times has the third machine been played since paying out?
9
Martha plays XXX times
Specific requirements: You must solve this using an object-oriented approach. Create a class called SlotMachine. Think about: What does a SlotMachine Have? What does it do? What information does it maintain? This is the state and behavior of the object. Each instance of this class will represent a single slot machine. Don�t put anything in the class unless it �belongs� to a single machine.
In the main method, create 3 instances of the slot machine to solve the problem in the spec. Play the machines in a loop.
========================================================================
my class
========================================================================
public class SlotMachine{
private int payOut;
private int playLimit;
private int counter;
public SlotMachine (int payOut, int playLimit){
this.payOut = payOut;
this.playLimit = playLimit;
public void setPayOut (int payOut){
this.payOut = payOut;
public int getPayOut(){
return payOut;
public void setPlayLimit (int playLimit){
this.playLimit = playLimit;
public int getPlayLimit(){
return playLimit;
public void slotCounter(){
counter = SavitchIn.readLineInt();
public int game(){
counter++;
if (counter == playLimit){
counter = 0;
return payOut - 1;
return -1; // the game method was edited by my professor but i'm still confused to make it work
=======================================================================
my main
=======================================================================
public class Gametesting{
public static void main(String[]args){
SlotMachine firstSlotMachine = new SlotMachine (2,3);
SlotMachine secondSlotMachine = new SlotMachine (2,3);
SlotMachine thirdSlotMachine = new SlotMachine (2,2);
int quarters;
int playerCount = 0;
System.out.println("How many quarters does Martha have in the jar?");
quarters = SavitchIn.readLineInt();
System.out.println("How many times has the first machine been played since paying out?");
firstSlotMachine.slotCounter();
System.out.println("How many times has the second machine been played since paying out?");
secondSlotMachine.slotCounter();
System.out.println("How many times has the third machine been played since paying out?");
thirdSlotMachine.slotCounter();
while (quarters != 0){
playerCount++;
quarters--;
firstSlotMachine.game();
if (quarters != 0){
playerCount++;
quarters--;
secondSlotMachine.game();
if (quarters != 0){
playerCount++;
quarters--;
thirdSlotMachine.game();
System.out.println("Martha plays " + playerCount + " times");

The main problem is that you made the first and second slot machine to pay out 2 quarters after 3 games and the third machine pay out two quarters after two games. That is not what your assignment specified.
SlotMachine firstSlotMachine = new SlotMachine (2,3);
SlotMachine secondSlotMachine = new SlotMachine (2,3);
SlotMachine thirdSlotMachine = new SlotMachine (2,2);
The second problem is that you never add the payout of a machine to Martha's number of quarters.
Look carefully at the way your professor implemented the game() method. If you think about it, what it returns is the net "gain" from playing a game. On jackpot it returns payOut -1 (jackpot less the one quarter Martha had to pay for the game), otherwise it returns -1 (Martha spends one quarter and wins nothing).
So what you can do is simply add the returned value to the number of quarters in the jar -
quarters = <machine>.game();
instead of quarters--.

Compare 'debug deployment' and 'development'

What are the differences between the debug deployment and the development version? I read the short text about the debug deployment version but this isn't enough for me.
Is it possible to do 'skip' and 'run selected steps'?
Or is there somewhere a nice table which compares the three versions, base debug and development?
Cheers Frank
Solved!
Go to Solution.

Hey Frank,
Here's a link: http://www.ni.com/teststand/depcompare.htm
However that still isn't as satisfying as I would like either so let me see if I can explain.
The development and the debug deployment are exactly the same except that you are ONLY supposed to use the debug version to debug your deployed sequences. Basically it allows you to have a sequence editor on the deployment machine for the sole purpose of debugging. That's how I understand it anyway. You can skip and run selected steps with the debug version.
Hope that helps,

Post material master idoc with class and characteristic values

Hi,
I need to post the class and characterstic values of material while posting the material using idoc of basic type matmas05 . Can anyone suggest me the fields and segment details to fill the class, class type and characteristic values in matmas05.
Note : the class and characteristic values are already created in the system, my purpose is to assign them to material while creating. so please give me the field and segment details in idoc basic type matmas05.
thanks
Kiran

I try to do the samething. I see the fields E1CUVAL : CU: Characteristic valuation in the structure of MATMAS05 but when I run the IDOC, these fields never appear even they exist for the material.
Did you find an answer to your question that can help me?
