Preamble

The configuration and testing described in this document have been done on Red Hat Enterprise Linux Server release 5.5 (Tikanga) 64 bits with Oracle 11gR2 (11.2.0.2.0) and 10gR2 (10.2.0.5.0).

First let your preferred system administrator install the product for you, you should find it in:

[root@oracleserver.domainname /]# ll /opt/tivoli/tsm/client

drwxr-xr-x 3 root bin  4096 Jun  7 15:27 lang
drwxr-xr-x 5 root root 4096 Jun  7 15:29 oracle

The Tivoli Storage Manager (TSM) server configuration part is in:

Oracle Configuration

The Oracle configuration is quite simple, you just need to create a symbolic link on TDPO library in all your $ORACLE_HOME/lib directory:

[oracleg@oracleserver.domainname ~]$ ln -s /opt/tivoli/tsm/client/oracle/bin64/libobk.so $ORACLE_HOME/lib
[oracle@oracleserver.domainname ~]$ ll  $ORACLE_HOME/lib/libobk.so
lrwxrwxrwx 1 oraracle dba 45 Jul 13 12:00 /oracle/software/lib/libobk.so -> /opt/tivoli/tsm/client/oracle/bin64/libobk.so

Then ensure dba Unix group (better to provide access to DBA group in case you have multiple Oracle accounts on your server) is able to write in all log files you defined in all TSM configuration files and be able to read tdpo.opt configuration file.

With Unix commands it gives something like:

[root@oracleserver.domainname /]# chmod a+r /opt/tivoli/tsm/client/oracle/bin64/tdpo.opt
[root@oracleserver.domainname /]# chown root:dba /opt/tivoli/tsm/client/oracle/bin64/tdpoerror.log
[root@oracleserver.domainname /]# chmod g+rw /opt/tivoli/tsm/client/oracle/bin64/tdpoerror.log
[root@oracleserver.domainname /]# chown -R root:dba /var/log/tsm
[root@oracleserver.domainname /]# chmod g+rw /var/log/tsm

All errors I personally encountered were linked to missing rights on either log files (write permission) and read rights on configuration files. Don’t be too generous while giving those rights…

And that’s it ! You are done, you can test all is working with (even before starting RMAN):

[oracle@oracleserver.domainname admin]$ sbttest test
The sbt function pointers are loaded from libobk.so library.
-- sbtinit succeeded
Return code -1 from sbtinit, bsercoer = 0, bsercerrno = 0
Message 0 not found;  product=RDBMS; facility=SBT

RMAN backup

I’m not entering in all options of powerful RMAN command but below simple script will perform your first tape backup:

#!/bin/ksh

release channel sbt1;

}
 
EOF
 
JOB_END=`date +%s`
echo "\nEnding at `date +'%Y%m%d_%H%M%S'`"
 
echo "\nCompleted in $((($JOB_END - $JOB_START)/60)) minutes"
 
echo "\nNormal Exit"

    Is there any method to retrieve the report for backup completion , via catlog server centrally , because most of the times we used crontab for scheduling .

  4. Anvik says:

    Hi Yannick,
    Is there a way to configure Oracle to archive the log files directly to TSM? Currently we have set it up to go to disk but we need them to go directly to TSM, just how it does for DB2. Any thoughts?

    Thanks in advance!
    Anvik

    • Yannick Jaquier says:

      Hi Anvik,

      Unless you can mount a “TSM filesystem” on your Oracle server, no I don’t think it is possible. Location parameter of LOG_ARCHIVE_DEST_n is either a local disk or te Fast Recovery Area. Overall I think it is a bit against the Oracle strategy to have the latest archived log files on disk to be able to recover quickly in case of failure…

      Thanks, Yannick.

    Hi Yannick,
    Really a good blog.I have a Q. I am taking my oracle online full bcks to TSM tape library.How can I restore them into another node ( purpose to use for DR).Probably You should have realized or experienced it before.

    • Yannick Jaquier says:

      Hi Cem,

      Thanks for nice comment I appreciate !

      No I have never done it but it’s a genuine request. To achieve it please refer to:
      How to achieve alternate client restore with RMAN and Tivoli (Doc ID 265595.1)

      In short you have to play with TDPO_NODE parameter in tdpo.opt file.

      Thanks, Yannick.

    Hi Yannick,

    Small and precise article. Great work man. It really cleared the funda of TDPO backup with TSM.

    Thanks a lot.

    I have configure RMAN backups through Tivoli. Rman backup is happing successfully and i am able to restore without any issue.But I want to delete rman backups from

    Tivoli. How do i achive this. Where i have set deletion policy? I have created seprate POOL and Management class in TSM.
    Is this RMAN backup is IMAGE or Arch format? If image format then i have to Version and If it archive format then i have to set Number of Days.

    As per my company policy i have keep rman backups for 3 sets/days.

    Please advice me.

    Please find below rman backup script and Management class details.

    Rman backup script:

    rman target /@RMAN_${ORACLE_SID} catalog /@RCAT  log=/shcilbin/RMAN_out/OfflineSHCILDW.$3$2$6.out APPEND  <<Eof
run{
sql 'alter system archive log current';
allocate channel dev1 type 'SBT_TAPE' parms="ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)";
allocate channel dev2 type 'SBT_TAPE' parms="ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)";
backup incremental level = 0 database format 'full_lvl0_DAILY_%T_%d_%u_%s_%p' filesperset 8;
backup current controlfile format 'bkpcontrol_%d_%T_%u_%s_%p.ctl' ;
}
Eof

      For cost constraint reason we have finally decided not to purchase expensive TDPO option and are doing backup on disk then on tape with standard TSM client.

      Just to say that we do not have huge production return on experience on this part.

      What I anyway remember is that either using retention policies (CONFIGURE RETENTION POLICY and CONFIGURE ARCHIVELOG DELETION POLICY) or using standard DELETE command was providing expected results during my testing even when working with tapes.

  10. Panou says:

    Hi Yannick,

    Is there any reason you set the SBT configuration twice ?
    A first time in the default RMAN configuration (CONFIGURE CHANNEL DEVICE TYPE sbt PARMS ‘ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)’;)
    and then again in the run block (allocate channel sbt1 type sbt parms ‘ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)’;)
    Why don’t you just run “allocate channel sbt1 type sbt” in the run block ?

    Regards,

    Hi Yannick,

    I find the blog truly useful for TDP backup configuration. Its a small guide to start with TDP backup in few minutes.

  12. Lodh says:

    Hello Yannick

    One thing which confuses me is that – You have switched off controlfile auto backu, then how will you restore your control files using TDPO & RMAN. The only way is to create new controlfiles, mount the DB and then go for rman restore. What say ?

    I tried restoring control file but it gives me the below message :-
    — RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP

    So i think we need to have a separate controlfile backup on disk somewhere ……

    • Yannick Jaquier says:

      Hi Lodh,

      Good and tricky question !

      If no controlfile autobackup and a recovery catalog then connect to recovery catalog and issue:

      Startup force nomount
restore controlfile;
alter database mount;
recover database;
Alter database open resetlogs;

      If no controlfile autobackup and no recovery catalog then it’s even complex because you would need to play with CATALOG command and restore few backupset from tape to local database server disk to catalog them… Not a safe situation for sure !

      Reading further Oracle documentation I now think controlfile autobackup is a good idea and do not use that much disk/tape space, so modifying my script: happy ?

      Please note that even with controlfile autobackup and no FRA, restore process is not that simple…

  13. Ivan Acosta says:

    Hi
    First I want tell you that this articule is very usefull thank you for share your knowledge, but I have a question. Is possible that this backup save in 2 device in tivoli and disk…??? Thanks for your answer.
