Rollback and Scheduling in Database?

If we use the Timestamp Ordering for concurrency control in following scheduling:
http://oi59.tinypic.com/260361k.jpg
My note says T2,T3,T5 is Run and T4,T5 is Rollback. I think it's false. any expert could help us? (i.e, in this schedule which of the Transaction Rollback and which one Is Done?

ISolation Level is not defined. would you please a default setting and consider more hint for me? why some rollback in this senario ?
default is read committed isolation. you are not helping us and yourself by not posting the details.
please post actual sql statements.. you can replace actual table names/column names to dummy names...
in forums, people(answerers) already do some sort of half guesses to interpret on question - on what might be issue(s). you can help us and yourself by providing more details and sql statements...
Hope it Helps!!

Oracle 10G Database Control and Scheduling OWB Process Flow

Does anyone know how to go about scheduling an OWB Process Flow from
Oracle 10G Data Base Control. I knew how to do this with Oracle Enterprise Manager 9.2 but we recently upgraded to Oracle Db 10G and the interface has changed significantly.
Now the interface seems to require a PL/SQL stored procedure to be executed.
Is there a template procedure that is installed with 10G Data Base Control as there was for 9.2 i.e. oem_exec_template.sql?
Thanks! Deadline approaching fast...
Marion

I've used the oem_exec_template.sql successfully with OWB 10.1 and Oracle 10G Database Control, with a little trial and error at first.
I'm assuming that your job execution environment is set up correctly, ie. that you can properly execute jobs via the host agent.
1. Log on to Database Control as SYSTEM, select Jobs from the links at the bottom of the page
2. In the Results section, Create Job, select "SQL Script" and press Go
3. In the General section, enter Job Name, and as SQL Script enter e.g.:
@/u01/app/oracle/owb_oracle_home/owb/rtp/sql/oem_exec_template.sql owb_runtime WF_LOC PROCESS MY_PROCESS , ,
4. In the Databases section, add your target database
5. In the Credentials section, I select "Override Preferred Credentials" and use the agent account (oracle on my Linux system) and db user owb_access (OWB Runtime Access user)
6. Review Schedule tab and submit
Comments on step 3:
- the oem_exec_template.sql script must be installed according to the path specified in step 3, on the database host where the OWB Runtime Repository is located
- owb_runtime is the owner of my OWB Runtime Repository
- WF_LOC is the name of my Workflow Location as seen in OWB Deployment Manager
- MY_PROCESS is the name of a deployed Workflow Process
- the commas indicate that I don't supply any system or custom parameters.
- step 3 is actually a shell command line that is interpreted by eg. /bin/sh on Unix or cmd on Windows, and must obey proper quoting rules. On windows, I had to specify the empty commas as "\," (including dblquotes)

[10gR2] RAC database and scheduler!!

Hi, all.
I have a 2 node RAC database.
And I have a plan to export a schema at a specific node(Node1),
because the disk for dump files is attached to Node1(not Node2).
I will do that by using "expdp utility" and scheduler.
However, how can I force oracle to do that ALWAYS at the Node1?
Are there any tips??
Thanks and Regards.

dbms_job has that functionality(not dbms_scheduler).
1. dbms_job.submit procedure has an parameter called "instance". By setting this parameter, you can force your job to be executed on the instance you specifed.
SQL> dbms_job.submit(..., instance=>1);
2. dbms_job.instance procedure makes your ready-made job to be executed on the specific instance.
SQL> dbms_job.instance(:job_no, 1);
Unfotunately, dbms_scheduler is wholy new feature and re-designed from dbms_job. Oracle just dropped that kind of functionality from dbms_scheduler
and implemented another approach which is called "instance stickiness".

Creating a job and scheduling a job error in OEM

Hi, Everyone,
I am trying to create and schedule a job thru OEM. In the the pl/sql block provide i have given my code like this
begin
SET SERVEROUTPUT ON;
SPOOL C:\RFV_PROFILE_REPORT.LOG APPEND;
SELECT TO_CHAR(SYSDATE, 'DD/MM/YY HH24:MI:SS') FROM DUAL;
EXEC PAC_RFV_PROFILE_REPORT.CALL_ALL (200910);
SELECT TO_CHAR(SYSDATE, 'DD/MM/YY HH24:MI:SS') FROM DUAL;
SPOOL OFF;
end;
i have created the job and scheduled it but i am getting this error:
Error # 6550
Details ORA-06550: line 2, column 5: PL/SQL: ORA-00922: missing or invalid option ORA-06550: line 2, column 1: PL/SQL: SQL Statement ignored ORA-06550: line 3, column 7: PLS-00103: Encountered the symbol "C" when expecting one of the following: := . ( @ % ;
could anyone pls help as this is very urgent.
Thanks in advance

Ah, the problem is you are confusing SQLPlus commands with PL/SQL.
SET SERVEROUTPUT ON; -- This is a SQLPlus command, not necessary here.
SPOOL C:\RFV_PROFILE_REPORT.LOG APPEND; -- This is a SQLPlus command, in PL/SQL to write out to a file you will need to call the UTL_FILE package to open a file for writing to. Except that the file you write to will appear on the database server, not your workstation, when the scheduled job runs.
SELECT TO_CHAR(SYSDATE, 'DD/MM/YY HH24:MI:SS') FROM DUAL; -- In PL/SQL you need to SELECT columns INTO variables FROM tables. But in fact I guess you want to write the time to file using UTL_FILE again. However, you don't really need to do this, since scheduler will log the start time and run duration itself.
EXEC PAC_RFV_PROFILE_REPORT.CALL_ALL (200910); -- This is the SQLPlus equivalent of the PL/SQL command:
BEGIN
PAC_RFV_PROFILE_REPORT.CALL_ALL (200910);
END;
SPOOL OFF; -- This is a SQLPlus command, not necessary here.
So to summarise, all you really need is:
BEGIN
PAC_RFV_PROFILE_REPORT.CALL_ALL (200910);
END;
And the scheduled job will log the start time and duration in the database, which you can find here:
SELECT * FROM USER_SCHEDULER_JOB_RUN_DETAILS

Shell Script for Startup and Shutdown the database

Hi,
i want Shell Script for Startup and Shutdown the database in Solaries.

Thanks & Regards,

SHUTDOWN
SHUTDOWN ABORT]
Shuts down a currently running Oracle instance, optionally closing and dismounting a database.
Terms
Refer to the following list for a description of each term or clause:
ABORT
Proceeds with the fastest possible shutdown of the database without waiting for calls to complete or users to disconnect.
Uncommitted transactions are not rolled back. Client SQL statements currently being processed are terminated. All users currently connected to the database are implicitly disconnected and the next database startup will require instance recovery.
You must use this option if a background process terminates abnormally.
IMMEDIATE
Does not wait for current calls to complete or users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
NORMAL
NORMAL is the default option which waits for users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
TRANSACTIONAL [LOCAL]
Performs a planned shutdown of an instance while allowing active transactions to complete first. It prevents clients from losing work without requiring all users to log off.
No client can start a new transaction on this instance. Attempting to start a new transaction results in disconnection. After completion of all transactions, any client still connected to the instance is disconnected. Now the instance shuts down just as it would if a SHUTDOWN IMMEDIATE statement was submitted. The next startup of the database will not require any instance recovery procedures.
The LOCAL mode specifies a transactional shutdown on the local instance only, so that it only waits on local transactions to complete, not all transactions. This is useful, for example, for scheduled outage maintenance.
Usage
SHUTDOWN with no arguments is equivalent to SHUTDOWN NORMAL.
You must be connected to a database as SYSOPER, or SYSDBA. You cannot connect via a multi-threaded server. For more information about connecting to a database, see the CONNECT command earlier in this chapter.

DB link problem between active Data Guard and report application database

My database version in 11.2.0.2.0 and OS is Oracle Solaris 10 9/10.
I am facing a problem in my Active data guard Database for reporting purpose. Active Data guard information is as below.
SQL> select name, database_role, open_mode from v$database;
NAME DATABASE_ROLE OPEN_MODE
ORCL PHYSICAL STANDBY READ ONLY WITH APPLY
Problem detail is below
I have created a db link (Name: DATADB_LINK) between active data guard and report application database for reporting purpose.
SQL> create database link DATADB_LINK connect to HR identified by hr using 'DRFUNPD';
Database link created.
But when I run a query using db link from my report application database I got this below error.
ORA-01555: snapshot too old: rollback segment number 10 with name "_SYSSMU10_4261549777$" too small
ORA-02063: preceding line from DATADB_LINK
Then I check Active Data Guard database alart log file and get below error
ORA-01555 caused by SQL statement below (SQL ID: 11yj3pucjguc8, Query Duration=1 sec, SCN: 0x0000.07c708c3):SELECT "A2"."BUSINESS_TRANSACTION_REFERENCE","A2"."BUSINESS_TRANSACTION_CODE",MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'feature' THEN "A1"."TRANS_DATA_VALUE" END ),MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'otherFeature' THEN "A1"."TRANS_DATA_VALUE" END )
But the interesting point if I run the report query directly in Active Data Guard database, I never got error.
So is it a problem of DB link between active Data Guard and other database?

Crystal Reports 2008 - automation and scheduling

Hey there Crystal Reports experts... please answer this question:
I've been evaluating the Crystal Reports 2008 package (client package) and have been able to generate some nice summary reports form our SQL database using summary pages which have multiple (up to 4) embedded sub-reports in them. I think it's doing what I need it to, but my next hurdle is to automate the summary report for 100+ different customers of ours. The criteria which changes for each customer is a table value in each subreport as well as the date range for the data on the report. I also need to have the title in the report header of each customer, change to reflect the different customer name and date range.
Is there a way to automate this with the standard Crystal Reports 2008 version? I've found a few 3rd party applications online that take care of the Crystal Report automation and scheduling as well as conditional data selection at the same time... is that what I need to use if we don't have ther server version of Crystal, or can I automate it using just the standard 2008 client version??

Hi,
Yes, you need the CR 2008 client license to create the reports and then the server license to distribute the reports.
CR Server 2008 is a single server reporting solution for distributing Crystal Reports only. BOE is a full BI server that can be scaled beyond a single server solution. In addition to just reporting it has other capabilities such as ad hoc query and analysis, dashboarding/scorecarding, etc.
CR Server 2008 currently does not include the "Publishing" functionality yet. Therefore, if you schedule the report to email, all users will see the exact same report. BOE XI 3.1 does have "Publishing" which lets you burst the report so that through a single schedule, each user only sees their slice of the data for that report. You can still use CR Server to accomplish something similar, but it would require you to setup an individual schedule per every customer where each schedule is configured to only return the appropriate data for that customer. This would require a little more effort to setup and maintain.

Creating a job and schedule

I have created a job via toad but it doesn't run by itself. .

Process Flow developing/deploying/executing and scheduling through OEM

I have installed OWB92 and Oracle 9i, OEM configured, Oracle workflow 2.6.2 installed. I know OWB and scheduling mapping from OEM.
I have created two mappings and a process flow. I want to schedule process flow from OEM. After creation of process flow, while I deploy it ask for a user/password/port/sid/host. I want to know which user I need to enter here.
If anybody help me out in the this regard providing the detail steps.
Thanks in advance.

Flashback database and Physical Standby databases

Hi,
We are thinking about the following scenario in our Production Standby databases. We are trying to do this to avoid number database cloning situations.
When we require live data to test data fixes :-
1. Switchover/failover the standby database.
2. opened this database in read write mode.
3. Apply the fix and test.
4. Flashing back the database prior to the SCN which did the switchover/failover.
5. Activate the standby again using a new standby controlfile.
Would you experts please comment on this idea?
Is this is possible? If so, would you please guide through the steps/some documentation.
Thanks in advance

This will not work according to me,
1)U can give previous SCN in rollback and gets the data till that SCN, but it will not become standby unless u make it a standby again manually by creating standy controlfile etc(may be this will be succesfull and limited up to check the data fixes).
2)Iif your first step succesfull then what about the fixes u test by applying patches using opatch and patchsets that cannot be rollbacked using flashback because they are copying new version files and adding some more configuration files to oracle home?.
There are lots of pitfalls and loop holes needed to be checked

Rollback and UNDO

Hi,
I'm confuse about Rollback and Undo concepts, can some one explain it to me please?
Felipe :)

This is a copy of a previous post I made some time ago:
There might be confusion while undo and rollback segment terms are used interchangeably in db world. It is due to the compatibility issue of oracle.
Undo
Oracle Database must have a method of maintaining information that is used to roll back, or undo, changes to the database. Such information consists of records of the actions of transactions, primarily before they are committed. These records are collectively referred to as undo.
Undo records are used to:
* Roll back transactions when a ROLLBACK statement is issued
* Recover the database
* Provide read consistency
* Analyze data as of an earlier point in time by using Flashback Query
When a ROLLBACK statement is issued, undo records are used to undo changes that were made to the database by the uncommitted transaction. During database recovery, undo records are used to undo any uncommitted changes applied from the redo log to the datafiles. Undo records provide read consistency by maintaining the before image of the data for users who are accessing the data at the same time that another user is changing it.
Undo vs Rollback
Earlier releases of Oracle Database used rollback segments to store undo. Oracle9i introduced automatic undo management, which simplifies undo space management by eliminating the complexities associated with rollback segment management. Oracle strongly recommends (Oracle 9i and on words) to use undo tablespace (automatic undo management) to manage undo rather than rollback segments.
To see the undo management mode and other undo related information of database-
SQL> show parameter undo
NAME TYPE VALUE
undo_management string AUTO
undo_retention integer 900
undo_tablespace string UNDOTBS1
Since the advent of Oracle9i, less time-consuming and suggested way is—using Automatic Undo Management—in which Oracle Database creates and manages rollback segments (now called “undo segments”) in a special-purpose undo tablespace. Unlike with rollback segments, we don’t need to create or manage individual undo segments—Oracle Database does that for you when you create the undo tablespace. All transactions in an instance share a single undo tablespace. Any executing transaction can consume free space in the undo tablespace, and when the transaction completes, its undo space is freed (depending on how it’s been sized and a few other factors, like undo retention). Thus, space for undo segments is dynamically allocated, consumed, freed, and reused—all under the control of Oracle Database, rather than manual management by someone.
Switching Rollback to Undo
1. We have to create an Undo tablespace. Oracle provides a function (10g and up) that provides information on how to size new undo tablespace based on the configuration and usage of the rollback segments in the system.
DECLARE
utbsiz_in_MB NUMBER;
BEGIN
utbsiz_in_MB ;= DBMS_UNDO_ADV.RBU_MIGRATION;
end;
CREATE UNDO TABLESPACE UNDOTBS
DATAFILE ‘/oradata/dbf/undotbs_1.dbf’
SIZE 100M AUTOEXTEND ON NEXT 10M
MAXSIZE UNLIMITED RETENTION NOGUARANTEE;
Note: In undo tablespace creation, “SEGMENT SPACE MANAGEMENT AUTO” can not be set
2.Change system parameters
SQL> alter system set undo_retention=900 scope=both;
SQL> alter system set undo_tablespace=UNDOTBS scope=both;
SQL> alter system set undo_management=AUTO scope=spfile;
SQL> shutdown immediate
SQL> startup
UNDO_MANAGEMENT is a static parameter. So database needs to be restarted.

DBA Cockpit: Planning calendar and remote Oracle databases- which method?

For using DBA Planning Calendar to schedule BR*Tools for remote Oracle database AS Java systems I have successfully implemented both the Secure Shell and SAP gateway methods in [Note 1025707 - DBA Cockpit: Planning calendar and remote Oracle databases|https://service.sap.com/sap/support/notes/1025707] and was interested in which of these two methods others have found to be more supportable and maintainable?
In more detail, the note has these two methods for non-ABAP remote systems:
2. Connection through Remote/Secure Shell
Specifically Secure Shell. Rejecting remote shell as too old and insecure a protocol.
3 Connection through SAP gateway
The note provides clues as to how these methods work. Expanding on that:
With #2, central ABAP system calls out to its OS user level to execute the ssh client (after gw/rem_start has been set to the non-default value SSH_SHELL) which it finds in the location specified in gw/ssh (default value is /usr/bin/ssh). It must use password-less authentication and the key-based authentication must also not require a passphrase. (Using ssh-agent is not an option since this is being called from SAP, not from your own script.)
It remotely runs via ssh a command, sapxpg, which must be found in the PATH of the remote user. (This is why the note, which has you place this exe sapxpg and a subset of the BR*Tools in the home dir of the remote user, also has you make sure the home dir is included in the path--your OS might or might not include the user's home dir in the path in the default shell environment for a new user.)
Then via sapxpg, the BR*Tools are invoked.
One thing that may be confusing here is you have to check at least one gateway parameter 'gw/...' in the central system to get the method #2 the non-gateway method to work--this is because the two methods are technically almost the same: in #2, secure shell is used to basically start a gateway on the fly with sapxpg in order to call the BR*Tools each time a DBA Planning Calendar action runs or you view DBA or Backup logs of the remote system from the central system. With #3, the gateway runs continuously on the remote system.
With #3, central system connects to remote SAP standalone gateway, which executes the BR*Tools installed in the standard SAP kernel directory of the SAP gateway. This method is simpler to describe so it sounds like it has less components than the secure shell method, however you do have an entire SAP system running, although it is just a standalone gateway.
Thoughts:
These pros/cons are UNIX/Linux-oriented since I assume most Windows environments do not have added 3rd-party products that provide secure shell so SAP gateway is the only method.
Secure shell
+ Less software required (not counting secure shell which comes with the operating system distribution): just a few SAP executables placed in the home dir of an ordinary user on the remote system.
+ Secure shell service probably automatically starts upon boot of the remote system operating system.
+ Secure shell is a widely used tool outside of SAP for executing commands remotely without passwords.
- Installation is non-standard: shell environment of remote user is not adapted by SAP installer since SAP installer is not used, SAP executables in the home dir of the remote user is non-standard. Has to be setup manually.
- Requires setting up secure shell key-based authentication, which should be known by UNIX/Linux admins or combined Basis/UNIX/Linux admins, but might be less familiar to SAP Web AS only admins.
- If your admin config policy is to have SAP interact as little possible with the OS level for interfaces with other systems, here you are relying on the OS-level secure shell.
- Using a private key that does not require a passphrase on the central system may not fit with your security policies if you have standards for secure shell configuration.
SAP gateway
+ The gateway is a standard installation, performed with SAP installation tool, with the exception of a few additional environment settings that have to be added after the installation. BR*Tools are installed in the standard location. Can use standard procedures for updating this software.
+ Only uses SAP software.
- More software on remote system: standalone gateway just to run BR*Tools and view logs.
- SAP Kernel of remote gateway should probably be updated whenever you do SAP kernel updates across your systems for consistency. One more system to update.
- Shell environment of remote user that runs the gateway looks like something setup by the SAP installer but is not standard because it has a few additional environment variables added.
- Need to make sure the SAP gateway is started on the remote system.

Hi Joe,
I configured a monitoring/dba landscape for two SAP Portals and one SAP BusinessObjects system on a SAP landscape by using DBACOCKPIT, at a customer site. These systems are running on AIX, Windows 2003/2008 servers and attached to the central monitoring system with standalone SAP gateway installations.
One another reason to not use OS based commands or 3rd party tools is security. We are stopping and disabling most of the services on OS where SAP system is running on, because of the security reasons. I faced more security gaps on rsh/ssh and the other tools than standalone SAP Gateway installations. As you can figure out that rsh/ssh is getting more attack than standalone SAP Gateway, because of well known by the IT world.
As a summary of it, this depends to point of view and policy of the IT organization. I applied both ssh and standalone SAP Gateway solutions at my customers, but I choose standalone SAP Gateway installation among of them.
Best regards,
Orkun Gedik
