My collegue have seen the the same thing before. 
They think the problem was with NetBackup and name-resolution and reverse
lookup, but they were not able to solve it properly.
They are going to reinstall netbackup software on the client soon.

Emne: [Veritas-bu] Problems with Veritas Netbackup via RMAN/Oracle


Hello everyone,
Recently I receive an error message reported by the hot_backup script -
which was up and running  for a few months:

Does anyone have any ideas on / encountered this errors?

I looked up several newsgroups/this mailing list archive, however still
haven't got any idea why it report ORA-19502.

I am using Netbackup Business server 3.4,
Solaris 8 Server,
Win2000 Client
Oracle Backup extension

Thanks & Regards,
Sunny Chan
