TDP Option File Error during Oracle Backup ;SBT error = 7011, errno = 2534, sbtopen: system error

I found this issue when dealing with Oracle DB backup where backup of multiple DB instances failed with SBT error = 7011, errno = 2534, sbtopen: system error.

Symptoms:

Database Buffers 327680000 bytes
Redo Buffers 532480 bytes
Database mounted.
SQL> Disconnected from Oracle8i Enterprise Edition Release <Release Number>
With the Partitioning option

==================================


 We notice that In Script to run the Oracle offline DB backup , the path to TDP Oracle option file was not correctly mentioned which leads to option file error.

SBT error = 7011, errno = 2534, The error 2534 correspond to the TDP message =>

ANU2534E Option file error

We checked in RMAN script that  $TDP8i_DIR is not set to tdpo option file under /usr/tivoli/tsm/client/oracle/bin64 instead it was set to /usr/tivoli/tsm/client/oracle/bin.


/usr/tivoli/tsm/client/oracle/bin64 # cd $TDP8i_DIR
/usr/bin/ksh: /usr/tivoli/tsm/client/oracle/bin:  not found.

Solution: Set the correct path of tdpo option file in parameter $TDP8i_DIR so that it should look for tdpo option file under usr/tivoli/tsm/client/oracle/bin64.

You can also use tdpoconf showenv -tdpo_optfile=/location of opt file/ to see if there is any issue.

Archive log not found during oracle DB backup

I notice an issue with TDP for Oracle where the COLD DB backup + Archive failed with below error.


Starting backup at Aug 13 2013 02:47:08
ORACLE error from target database:
ORA-00258: manual archiving in NOARCHIVELOG mode must identify log

ORA-27037: unable to obtain file status
IBM AIX RISC System/6000 Error: 2: No such file or directory
Additional information: 3




===================================

The above error means there is a problem with Archive log file.

First we should check the log file under given location /Path/to/oracle/archlog

--------------------------------------
//Path/to/oracle/archlog # ls -ltr Log name_96_1_822820066.arc
Log name_96_1_822820066.arc  not found
-------------------------------------

This means that during backup RMAN is looking for a log which does not exist. It may be possible the this log might have been deleted accidently by DBA, but since log file not found backup can not be completed. Here are some possible solutions:


1- Ask your DBA to do a crosscheck of backup ( using RMAN command) which will check the status of log and mark it expire or tell the catalog to NOT ask for this log during recovery time.

command >
RMAN> crosscheck backup;

specification does not match any backup in the repository

2- Check the size of FS which may lead to this issue.

run  df -g ( in AIX) to check the size of FS used. If FS is 100 %, make sure you have enough space in FS to have a backup.
