NetBackup status code: 2505

Message: Unable to connect to the database

Explanation: A backup job may go active and allocate backup resources, but then fail with the error below that is reported in the Job Details:

Error bpbrm(pid=27145) db_FLISTsend failed: Unable to connect 
to the database (2505)

In addition, the bptm process may report the following error:

Warning bptm(pid=27162) cannot update image database to add 
completed fragment, error = Unable to connect to the database 
Info bptm(pid=27162) EXITING with status 252 <---------- 

This error can be caused by a lack of semaphore tuning within the kernel. This error cannot be resolved by NetBackup.

Recommended Action: In this case, the semmni value was insufficient at 128. By increasing this value to 1024, the ODBC connection was successful and NetBackup then ran successfully. Although this could affect other platforms, this error has been seen in multiple RedHat Enterprise Linux (RHEL) environments, usually when the RHEL system is the NetBackup master server. Any supported version of NetBackup could be affected by this environmental issue. See the Recommended NetBackup UNIX / Linux semaphore tuning values (Linux/Solaris/HP-UX/AIX) article at the following location for general recommendations and refer to the platform vendor support for additional details:
