Differences between Linux and Solaris command set

Hi,
It is complicated to learn Solaris? Is the set of commands the same of Linux?
It is because is more simple for me to find a Linux Admin book than a Solaris book.
Thanks.
Lorenzo

BTW: You might want to start with this peace if information:
http://wwws.sun.com/software/whitepapers/linux/linux_overview.pdf
One remark: this Blue/white paper is written for audience known to Solaris and new to Linux, but usefull the other way around.
Specially table 1 is very usefull !
Good luck, and Welcome as new Solaris Administrator.
Eric.

Difference between SXPG_COMMAND_EXECUTE and Open data set mechanism

Can you please help me to know the difference between moving a file using FM "SXPG_COMMAND_EXECUTE" and moving file using "open data set - transfer file- close data set" mechanism?

Through 'SXPG_COMMAND_EXECUTE' u can execute a External command (ie.. UNIX /Windows/OS/400) In ABAP programming..
for Conversion Of Aplication server File/Move the file from one directory to Other...
The Command must be present in SM69.
Using this function module'SXPG_COMMAND_EXECUTE' , you can check the authorization of a user to execute a particular external command and run the command:
With the arguments specified in ADDITIONAL_PARAMETERS
On the target host system defined by OPERATINGSYSTEM and TARGETSYSTEM
If an SAP profile parameter is inserted in the portion of the command stored in the database, then the value of this parameter is substituted into the command. If an SAP application server is active on the target system (TARGETSYSTEM), then the profile parameter values are read from the profile that is active on that system. No parameter substitution is made in ADDITIONAL_PARAMETERS.
After substitution, the command is checked for the presence of "dangerous" characters such as the semicolon ( ; ) on UNIX systems.
If an additional "security function module" is specified in the command definition, this function module is also called in the course of processingebenfalls. This function module can prevent execution of the command.
If the authorization checks complete successfully, the command is run on the target host system.
Through Open Data Set u can read and write the file in the same directory...
Thnaks,
SD

Difference between srvctl and crsctl commands

may be I am wrong but I want to know what is the difference betweens stopping service using srvctl and crsctl utilities.
./crsctl stop resource <service.srv> –f
./crsctl stop resource ora.<service>.cs –f
and
srvctl stop service -d <database> -s <service>
Also what is the <servicename>.cs ? I know service.srv and its purpose but .cs resource.
Please share document or link wheren I can have more details of services.
Thanks

In a very generic way, CRSCTL commands would require a sudo access and the SRVCTL can be run by the grid or oracle user. I haven't checked the docs but as a guess, the +.cs+ would be cluster service as in RAC, everything runs as a service and in 11.2 as a resource.

Difference between Gmail and Exchange when setting up email

Hi all,
When adding my Gmail email details in Settings in iOS7 (Via Settings > Mail, Contacts, Calendars > Add Account) I’m presented with the options to use Exchange or Google.
I know back in the early days of the iOS it was always preferable to use Exchange as it synced everything on your phone perfectly (mail, contacts, calendar) but it seems that now the Google option is just as good…?
Other than the capability to push emails to my device (a function that I don't use anyway), is there any other difference between the Exchange and Google options when setting up email?
Thanks,
David

I've tested it out on my iOS7 5s; the calendar and contact syncing seems to work absolutely fine though?
This was in reference to the Google option. It syncs mail, calendar, contacts and notes all absolutely fine as far as I can see - I wanted to check I wasn't missing anything.
Any need to get narky there?

Differences between Soalris and Solaris Express /Developer Edition

Hi
Thank you for readingn my post
What is different between Solaris Express (Developer Edition) and solaris OS?
Are they the same and with same capabilities?
Can I install S1 Grid suite in a Express edition?
Thanks

Solaris 10 (with several updates) is the current release version of the Solaris operating system.
Since the release in '05, Sun has been developing the "next" version of Solaris. Using the OpenSolaris code as a base, this version is codenamed "Nevada". Periodic builds of this version are available as Solaris Express. So you get more up-to-date drivers, features, and bugs from it. Because it's under development, there are no patches. Instead you'd need to upgrade to the next release (or create your own patch).
I haven't looked specifically at S1 Grid, so it very likely will install. However installations on Solaris Express may not be a supported configuration if you need that.

What's the difference between R/3 Enterprise extension set 1.10 and 2.00 ?

Hi there,
Anyone know how to find the difference between 47x110 and 47x200. I want to install the new IDES R3 which is 47x200 (I found some program/source that I need in this version). But our PRD system is 47x110.
thanks in advance,
Doris

Hi Doris
SAP R/3 Enterprise Core has been assigned the release number
4.70. This signifies its similarity to SAP R/3 4.6C and indicates
that the core can be independently upgraded and maintained.
SAP R/3 Enterprise Extensions are selectively deployable and
have their own release cycles. The name of each SAP R/3 Enterprise Extension reflects its relevant application area.
e.g.
SAP R/3 Enterprise Extension Set 1.10 includes HR,SCM and Fin modules
SAP R/3 Enterprise Extension Set 2.00 includes all above and additionaly PLM module.

What is the difference between ws_upload and gui_upload

what is the difference between ws_upload and gui_upload
what is the difference between ws_download and gui_down load
pls tell briefly

Hi Kuamr,
UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
Hope this resolves your query.
Reward all the helpful answers.

Differences between LSMW and BDC

Hi All
Please can you give me the few points about the differences between LSMW and BDC?
Awaiting for your Responce

THERE IS THREE TYPE OF METHOD IN BDC
BDC SESSION
CALL TRANSACTION
CALL DIALOG
What is BDC or batch input
The Batch Input is a SAP technic that allows automating the input in transactions. It lies on a BDC (Batch Data Commands) scenario.
BDC functions:
· BDC_OPEN_GROUP : Opens a session group
· BDC_CLOSE_GROUP : Closes a session
· BDC_INSERT : Insert a BDC scenario in the session
· The ABAP statement "CALL TRANSACTION" is also called to run directly a transaction from its BDC table.
It runs the program RSBDCSUB in order to launch automatically the session. The session management is done through the transaction code SM35.
The object itself is maintanable through the transaction SE24.
BDC methods:
Method
Description
Parameters
OPEN_SESSION
Opens a session
SUBRC (Return Code 0 OK)
SESSIONNAME (Session to be created)
CLOSE_SESSION
Closes a session
None
RESET_BDCDATA
Resets the BDC Internal Table...
None. Normally, for internal purpose
BDC_DYNPRO
Handles a new screen
PROGNAME (Name of the program)
DYNPRONR (Screen Number)
BDC_FIELD
Puts a value on the screen
FIELDNAME (Name of the field)
FIELDVALUE (Value to be passed)
CONSTRUCTOR
Constructor - Initializes NO_DATA
NODATA (No data character). The constructor is called automatically when the object is created.
RUN_SESSION
Launches a session with RSBDCBTC
None
CALL_TRANSACTION
Calls a transaction with the current BDC Data
MODE (Display Mode)
UPDATE (Update Mode)
TCODE (Transaction to be called)
BDC_INSERT
Inserts the BDC scenario in the session
TCODE (Transaction to be called)
BDC techniques used in programs:
1) Building a BDC table and calling a transaction,
2) Building a session and a set of BDC scenarios and keeping the session available in SM35,
3) Building a session and lauching the transaction right after closing the session.
BDC using Call Transaction
BDC using Call transaction involves calling an SAP transaction in back ground from within the ABAP
program. The process involves building an Internal BDC table containing the screen information needed to
execute the required transaction and then passing this to the Call transaction command (See code example).
The full procedure for creating a BDC program is as follows:
What is the difference between batch input and call transaction in BDC?
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
BATINPUT/DIRECT INPUT
A: Batch-inputs can not be used to fill the "delivery due list" screen because it is not a dynpro. This is a standard SAP report. A SAP report (check with "System -> Status") may be called using SUBMIT sentence with the appropriate options . It is preferred to call a report than create a Batch-input program.

The LSM Workbench is an SAP R/3 based tool that supports the one-time or periodic transfer of data from non-SAP systems ("legacy systems") to SAP systems.
The LSM Workbench helps you to organize your data migration project and guides you through the process by using a clear sequence of steps.
The most common conversion rules are predefined. Reusable conversion rules assure consistent data conversion for different data objects.
LSMW vs DX Workbench
The LSM Workbench covers the following steps:
Read the legacy data from one or several files (e.g. spreadsheet tables, sequential files).
Convert the data from source format to target format.
Import the data using standard interfaces (Batch Input, Direct Input, BAPI, IDoc).
Experiences made in successful implementation projects have shown that using the LSM Workbench significantly contributes to accelerating data migration.
SAP provides this tool along with documentation to customers and partners free of charge.
Users of the LSM Workbench receive the usual support via SAP Net - R/3 Frontend (component BC-SRV-DX-LSM).
Releases:
Version 1.7.2 of the LSM Workbench ("LSMW 1.7.2") available
Attention : LSMW 1.7.2 requires an SAP R/3 system with SAP R/3 4.0 or SAP R/3 4.5.
Version 1.8.0 of the LSM Workbench (1.21mb) ("LSMW 1.8.0") available
Attention : LSMW 1.8.0 requires an SAP R/3 system with SAP R/3 4.6.
Version 3.0 of the LSM Workbench (1.89mb) ("LSMW 3.0") available for Web Application Server 6.10
Attention : LSMW 3.0 requires a SAP WAS 6.10. Functionality of version 1.7.2 and 3.0 are identical !
Version 4.0 of the LSM Workbench ("LSMW 4.0") integrated in Web Application Server 6.20
Attention : LSMW 4.0 is an integrated part of SAP WAS 6.20.

What are the Basic Differences between Oracle and MS-SQL server Database?

Hello,
anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
Regards,
Balaram

SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
The SQL Server advantages:
SQL Server holds the top TPC-C performance and price/performance results.
SQL Server is generally accepted as easier to install, use and manage.
The Oracle Database advantages:
Oracle Database supports all known platforms, not only the Windows-based platforms.
PL/SQL is more powerful language than T-SQL.
More fine-tuning to the configuration can be done via start-up parameters.

[Q] what is different of mail sending between HPUX and Solaris ??

All,
Would somebody let me know what different of mail sending between HPUX and Solaris is ?
I have several unix servers and some are HPUX 11.11 and some are Solaris v8.
To use "mailx" command in maintenance scripts, I set a relay server in sendmail.cf of /etc/mail.
What I'm curious is
,in HPUX, "mailx" is working without sendmail daemon. but in Solaris, "mailx" is not working without sendmail daemon.
I'm not good at those sendmail site. my knowldge of UNIX is very general, not specific and expertized. so need your help.
Why it works without sendmail daemon on HPUX, and why not on SUN which is not working sendmail daemon ??

Hi,
do you have a mailhost entry in /etc/hosts pointing to your relay hsot?

What is the difference between tkprof and explainplan

Hi,
what is the difference between tkprof and explainplan.

Execution Plans and the EXPLAIN PLAN Statement
Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
The columns that make up the plan table are as follows:
Name Null? Type
STATEMENT_ID VARCHAR2(30)
TIMESTAMP DATE
REMARKS VARCHAR2(80)
OPERATION VARCHAR2(30)
OPTIONS VARCHAR2(30)
OBJECT_NODE VARCHAR2(128)
OBJECT_OWNER VARCHAR2(30)
OBJECT_NAME VARCHAR2(30)
OBJECT_INSTANCE NUMBER(38)
OBJECT_TYPE VARCHAR2(30)
OPTIMIZER VARCHAR2(255)
SEARCH_COLUMNS NUMBER
ID NUMBER(38)
PARENT_ID NUMBER(38)
POSITION NUMBER(38)
COST NUMBER(38)
CARDINALITY NUMBER(38)
BYTES NUMBER(38)
OTHER_TAG VARCHAR2(255)
PARTITION_START VARCHAR2(255)
PARTITION_STOP VARCHAR2(255)
PARTITION_ID NUMBER(38)
OTHER LONG
DISTRIBUTION VARCHAR2(30)
There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
Trace Files and the TKPROF Utility
TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

What is the difference between MOVE and WRITE TO ststement?

Hi
What is the difference between MOVE and WRITE TO ststement?
When do we use both of them?
Thank You

Hi,
<b>MOVE</b>
Syntax
MOVE source {TO|?TO} destination.
destination {=|?=} source.
Effect
Both these statements assign the content of the operand source to the data object destination. The variants with the language element TO or the assignment operator = are valid for all assignments between operands that are not reference variables, and for assignments between reference variables for which the static type of source is more specific than or the same as the static type of destination(narrowing cast).
Variants with the language element ?TO or the assignment operator ?= (casting operator ) must be used if the source and destination are reference variables and the static type of source is more general than the static type of destination (widening cast). For assignments between operands that are not reference variables, use of the question mark ? is not permitted.
The data object destination can be any data object that can be listed at a write position, and the data object source can be a data object, a predefined function or a functional method (as of release 6.10). The data type of the data object destination must either be compatible with the data type of source, or it must be possible to convert the content of source into the data type of destination according to one of the conversion rules.
Notes
If source and/or destination are field symbols, then, as in all ABAP commands, the system works with the content of the data objects to which the field symbols point. The actual pointer content of a field symbol can only be changed using the statement ASSIGN or the addition ASSIGNING when processing internal tables (value semantics). If source and destination are reference variables, the reference contained in source is assigned to destination (reference semantics).
Strings and internal tables are addressed internally using references. When assignments are made between strings and between internal tables (as of release 6.10), only the reference is transferred, for performance reasons. After the assignment, the actual string or the actual table body of the source as well as the target object are addressed (sharing). When the object is accessed to change it, the sharing is canceled and a copy of the content is made. The sharing is displayed in the memory consumption display of the ABAP debugger and in the Memory Inspector tool (as of release 6.20).

Syntax Diagram
WRITE - TO
Syntax
WRITE {source|(source_name)} TO destination
                             [int_format_options].
Effect:
This statement assigns the formatted content of the data object source, or the formatted content of the data object whose name is contained in source_name, to the data object destination. The data objects source_name and destination must be character type and flat. source_name can contain the name of the data object to be assigned in upper or lower case. If the data object specified in source_name does not exist, the assignment is not executed, and sy-subrc is set to 4.
The statement WRITE TO has the same effect as the statement WRITE for lists. This statement formats the content of source or the source field specified in source_name as described in the field. It does not, however, store the result in an output area of a list in the list buffer, but instead stores it in a variable. The output length is determined by the length of the variable.
The same additions int_format_options can be specified for formatting the content as in the statement WRITE for lists, except for NO-GAP and UNDER.
System fields
sy-subrc Meaning
0 The data object specified in source_name was found and the assignment was executed.
4 The data object specified in source_name was not found and the assignment was not executed.
For the static specification of source, sy-subrc is not set.
Note:
If destination is specified as an untyped field symbol or an untyped formal parameter, and is not flat and character-type when the statement is executed, this leads to an untreatable exception in a Unicode program. In non-Unicode programs, this only leads to an exception for deep types. Flat types are handled as character-type data types.
Example:
After the assignment, the variables date_short and date_long receive the current date in the order specified in the user master record. The variable date_long also contains the defined separators, as the output length is sufficiently long. The content of the variable date_mask is formatted according to the formatting addition DD/MM/YY.
DATA: date_short(8) TYPE c,
      date_long(10) TYPE c,
      date_mask(8) TYPE c.
WRITE sy-datum TO: date_short,
                   date_long,
                   date_mask DD/MM/YY.
Exceptions
Non-Catchable Exceptions
Cause: Negative length specified for offset/length
Runtime Error: WRITE_TO_LENGTH_NEGATIVE
Cause: Negative offset specified in offset/length
Runtime Error: WRITE_TO_OFFSET_NEGATIVE
Cause: Offset specified in offset/length specification is longer than the field length.
Runtime Error: WRITE_TO_OFFSET_TOOLARGE
