Sybase Backup stuck and no child jobs are created.

Is this a new setup that has never worked before?

Or worked before and now having issues?

Have you created log folders as per the Troubleshooting section of  NetBackup for Sybase Administrator's Guide ?

What do you see in the logs?
Is any process started on the Sybase client?

 

Adding to Marianne's post, check bphdb logs what you script is doing and where it has stuck.. 

post bphdb logs

What does the sybase DBA see in their logs ?

What state are the problematic instance in ?

Thanks for the comments guys. there were hang NBU processess which was leading this problem.

I just cancelled the parent job and restarted it again and it worked.
