Database backup to TSM returns SQL2033N with TSM reason code 36

Technote (troubleshooting)


Problem(Abstract)

TSM API reason code "36" is received:

1) You might receive the following error when performing a database backup to Tivoli Storage Manager (TSM):
SQL2033N An error occurred while accessing TSM during the
processing of a database utility. TSM reason code: "36".
or
SQL2062N An error occurred while accessing media
"/home/db2inst8/sqllib/adsm/libtsm.a". Reason code: "36".

2) archive of LOG Files to TSM does not work because of TSM API rc = 36

Symptom

1) Database backup to TSM fails with SQL2033N (SQL2062N) and TSM reason code: "36" if database configuration parameter VENDOROPT is set.

2) Archiving of database LOG Files to TSM does not work and fails with TSM API rc = 36 if LOGARCHOPT1 (LOGARCHOPT2) is set.

Cause

The implementation of TSM APAR IC49231 is the cause of the problem. An application using FromNode or FromOwner will be prevented from doing a backup or archive.

APAR description:
TSM API DOES NOT BLOCK SESSIONS WITH FROMNODE OR FROMOWNER FROM
PERFORMING BACKUPS UP OR ARCHIVES
http://www-01.ibm.com/support/docview.wss?uid=swg1IC49231

One example why VENDOROPT may be set:
In a DB2 HADR environment, it is needed to use "-fromnode" and "-fromowner" option in the DB2 database configuration parameter VENDOROPT for the stand-by database to be able to receive LOAD copies from the primary machine through TSM. If a HADR takeover takes place, the old primary database becomes a stand-by and needs to set the parameters in their database configuration to point to the old stand-by (now primary) machine.
AND it is needed to remove the VENDOROPT value from the new primary machine. If this is not done, the error SQL2033N (SQL2062N) with TSM reason code: "36" will occur.

If used, the HADR takeover script needs to set and reset the VENDOROPT and/or LOGARCHOPT1/LOGARCHOPT2 values.


Diagnosing the problem

Find the return code structure that was returned from TSM in the db2diag.log. It shows TSM rc "36".

Resolving the problem

Do not set VENDOROPT or LOGARCHOPT1 (LOGARCHOPT2) in the database configuration if database backups needs to be done.

Modify the HADR takeover script to set and reset the LOGARCHOPT1 (LOGARCHOPT2) values.
