ANR2968E Database backup terminated. DB2 sqlcode: -2033. DB2 sqlerrmc: 292

Technote (troubleshooting)


A Tivoli Storage Manager server database backup process is launched and fails with the ANN2968E error. Because the database backup fails to run, the recovery log fills up and crashes the server.


The db2diag log file may also show the following error :

Insufficient AIX system resource

Diagnosing the problem

The database backup fails with sqlerrmc: 292 which indicates a Tivoli Storage Manager API return code of 292. This return code is defined as follows :

#define DSM_RC_TCA_FORK_FAILED 292 /* Error forking off TCA process */
This indicates that the API was unable to fork a process to do its database backup.

Resolving the problem

The error indicates that the AIX "Maximum number of PROCESSES allowed per user" (maxuproc) value is too low. It is necessary to increase this value to solve this issue. In this particular case, the maxuproc value was set to 128 and was increased to 4096 using the following commands.

Use the following command to verify the current value :
lsattr –l sys0 –E | grep maxuproc

Use the following command to change the value to 4096
chdev –l sys0 –a maxuproc=’4096’
