How to run automated maintenance task on a logical standby database ?

Hi
I realize that i do not see any job runs for automated maintenance tasks on my logical standby database.
Which are the conditions that must be fulfilled for automated maintenance tasks to run?
Thanks
Christoph

Hi,
In an Oracle Data Guard environment, the Scheduler includes additional support for two database roles: primary and logical standby. You can configure a job to run only when the database is in the primary role or only when the database is in the logical standby role. To do so, you set the database_role attribute. This example explains how to enable a job to run in both database roles. The method used is to create two copies of the job and assign a different database_role attribute to each.
By default, a job runs when the database is in the role that it was in when the job was created. You can run the same job in both roles using the following steps:
Copy the job
Enable the new job
Change the database_role attribute of the new job to the required role
The example starts by creating a job called primary_job on the primary database. It then makes a copy of this job and sets its database_role attribute to 'LOGICAL STANDBY'. If the primary database then becomes a logical standby, the job continues to run according to its schedule.
More Information please cheek below link:

Thank you

  • How to delete the foreign archivelogs in a Logical Standby database

    How do I remove the foreign archive logs that are being sent to my logical standby database. I have files in the FRA of ASM going back weeks ago. I thought RMAN would delete them.
    I am doing hot backups of the databases to FRA for both databases. Using ASM, FRA, in a Data Guard environment.
    I am not backing up anything to tape yet.
    The ASM FRA foreign_archivelog directory on the logical standby FRA keeps growing and nothing is get deleted when
    I run the following command every day.
    delete expired backup;
    delete noprompt force obsolete;
    Primary database RMAN settings (Not all of them)
    CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 9 DAYS;
    CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
    CONFIGURE DB_UNIQUE_NAME 'WMRTPRD' CONNECT IDENTIFIER 'WMRTPRD_CWY';
    CONFIGURE DB_UNIQUE_NAME 'WMRTPRD2' CONNECT IDENTIFIER 'WMRTPRD2_CWY';
    CONFIGURE DB_UNIQUE_NAME 'WMRTPRD3' CONNECT IDENTIFIER 'WMRTPRD3_DG';

    How do I cleanup/delete the old ASM foreign_archivelog files?

    OK, the default is TRUE which is what it is now
    from DBA_LOGSTDBY_PARAMETERS
    LOG_AUTO_DELETE     TRUE          SYSTEM     YES
    I am not talking about deleting the Archive logs files for the Logical database that it is creating, but the Standby archive log files being sent to the Logical Database after they have been applied.

  • EXECUTE permission denied on sp_sqlagent_log_jobhistory when running a maintenance task or sql job

    Hi folks,
    I have a scheduled maintenance plan and associated jobs in SQL Server 2008 SP2 that have been working but stopped about two months ago. When I run a maintenance task or sql job using any account (sa, sysadmin-priveleged domain account, etc) I get the following
    entries in the SQL Server Agent log (see below). I've tried changing the SQL Server Agent account, applied the latest hotfixes (CU2 for 2008 SP2) and set permissions manually so that the service accounts have dbo access to the msdb database. Anyone got other
    ideas? I've avoided recreating the msdb database, but that may be my only option.

    And just to add to the confusion - I created a SQL login called sql-maintjobs and have it sysadmin priveleges. I then logged in to SQL using this account on the instance that is failing and ran the following:

    This sql worked fine - no permission errors at all. That would suggest the account does have permission to EXECUTE that stored procedure... very confusing!

  • How to remove logical standby database configuration cleanly

    Hello,
    We are on RHL with 11.2.0.3 DB version. Due to various unknown reasons we would like to recreate logical standby database and for that purpose I would like to cleanly remove/uninstall/drop LOGICAL STANDBY DATABASE from the DATA GUARD configuration we have.
    The DG setup already has 1 PHYSICAL STANDBY DATABASE which is working fine. PRIM,PHYSICAL, and LOGICAL all are on different HOSTS. Could you please guide or suggest us exact MOS Doc id regarding this? I have found one MOS Doc id which is close enough but its steps include removing dg configuration completely which I don't want. Only Logical Standby database needs to be remove cleanly so that it can be installed again properly.
    We are using GRID CONTROL and DATA GUARD BROKER.

  • How to monitor SQL Apply for 10.2.0.3 logical standby database

    We have a logical standby database setup for reporting purposes. Users want to monitor whether sql apply is working or failed closely as it has reporting repercations.
    In case of 9i databases , there was "Data Not Applied (logs)" metric which we used for alerting and paging, in case a backlog of more than 5 log files developed.
    With 10.2.0.3 onwards, the metric no more exists.
    I would like to learn from other, how to monitor the setup, so that if the backlog in logs shipping or applying develops, we get page.
    Regards.

    Sorry, didn't read ur post in a hurry. Below article (http://www.freelists.org/post/oracle-l/Any-quick-way-to-remove-histograms,13) removes histogram without re-analyzing the table. Hope that helps!!!

    but with only 1 bucket (i.e. no histograms).You might try the attached script, that reads the stats using
    dbms_stats.get_column_stats and re-sets them, minus the histogram,
    using dbms_stats.set_column_stats.
    I haven't fully tested it - it's only 10 minutes old, even if Ihave
    slightly modified for you another script I've used for quite some
    time - and the spool on 10.2.0.3 seems to confirmthat the histogram
    is, indeed, removed, while all the other statistics are preserved.I
    have also reset density to 1/num_distinct, that is the value youget
    if no histogram is collected.regards,

  • How to convert logical standby database to Physical Standby Database

    Hi,
    Does anyone know how to convert logical standby database(10.2.0.3) to Physical Standby Database(10.2.0.3)? Is this possible? If so,please give me steps for it.
    Thanks.
    Regards,
    RJ.

    I don't believe this to be possible. One of the steps invloved in the creation of a logical standby is the following:
    ALTER DATABASE OPEN RESETLOGS;
    This makes the logical standby a different incarnation of the db from the primary.
    A physical standby is a binary copy of a primary db, a logical standby is a completely seperate db that just happens to get sql statements applied to it that are generated from a primary db, but is open read/write.
    One avenue, though would be if you had flashback database enabled and you flashed back all the way to when the db was a physical standby and then rolled forward with the archived redo logs.
    It's somewhat unlikely you are in that situation, but that is a possibility.
    Indeed the 11g snapshot standby does this sort of thing:

  • Enable Re-Indexing Maintenance Task for SCCM 2012 R2 Database?

    If I use the
    MaintenanceSolution.sql script provided by Ola Hallengren here: 
    http://ola.hallengren.com/sql-server-index-and-statistics-maintenance.html
    and then use this SQL script weekly to rebuild the SCCM 2012 R2 indexes:
    EXECUTE dbo.IndexOptimize
    @Databases = 'USER_DATABASES',
    @FragmentationLow = NULL,
    @FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
    @FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
    @FragmentationLevel1 = 5,
    @FragmentationLevel2 = 30,
    @UpdateStatistics = 'ALL',
    @OnlyModifiedStatistics = 'Y'
    Then do I still need to enable the built-in database re-indexing maintenance task in the SCCM 2012 R2 console?
    Thanks 

    In the Channel9 video, the statement is made that the  built in Rebuild Indexes "maintenance task does not always work and that it is kind of broken, but it works sometimes and not always." Can anyone provide further
    details regarding the state of the Rebuild Indexes
    maintenance task? Why does it only sometimes work? Should it be used at all? Has it been fixed with a CU since the video came out? Are there plans to fix it?

  • How to find the timestamp and SCN in the standby database?

    Hai,
    I have Oracle 9.2.0.4 RAC with 2 nodes in the production. The logs generated at these servers will be manully moved to my standby database and will be applied. To know what isthe maximum log files applied in the standby database, i am using the below mentioned query in the standby database,
    Select thread#,max(sequence#) from v$log_history group by thread#
    In general i am using "recover standby database until cancel" command and then checking the database with the above mentioned query whether all the logs are applied or not.
    If i use time based or scn based recovery in standby database i.e., "recover standby database until time <time>" or "recover standby database until change <scn number>" , after completion of the recovery, apart from the message "Media recovery complete" or by seeing the alert log, is there any way to query the standby database, so that i can identify the time or scn upto which the archived redo log files got applied.

    Hi Sridhar,
    There should be some view which will have applied_scn information. There is one more option i can suggest, you can create a heart beat table in production with 2 column like scn and timestamp. Update this table every minute. From standby db you can query this table and get fair idea on applied_scn and timestamp.
    While exporting you can export using flashback_scn by taking the value from heartbeat table of standby.
    This heartbeat table is used very common in streams environment. Just see if this helps you.

  • How to apply the changes in logical standby database

    Hi,
    I am new to Dataguard. I am now using 10.2.0.3 and followed the steps from Oracle Data Guard Concepts and Administration Guide to setup a logical standby database.
    When I insert a record to a table from the primary database side, when i query the same table from the logical standby database, it doesn't show the new records.
    Did I miss something? What I want to do is when I insert a record in the primary db, then the corresponding record will be inserted in the standby db.
    Or I totally misunderstand what Oracle data guard is? Any help are appreciated.
