Re: [Veritas-bu] RMAN and MS-SQL Backup Fail - Error 21

I have been working the same issue
We think it has come down to a network
issue as my throughput cratered to about 300 kbps.
My fist thought is look for any network –
card, cable, switch issues.

Subject: [Veritas-bu] RMAN and
MS-SQL Backup Fail - Error 21
Master is Windows 2003 SP2 x86 running NBU
6.5.3 and clients are a mix of Windows 2000, 2003, x86, x64 running NBU 5.1 MP4
& 5.
I've got the oddest issue I've been
working two weeks. Two weekends ago my RMAN and MS-SQL backups began
failing with errors 21. The jobs don't fail right away, and not every job
fails. An RMAN job might write none or all but one of its datasets than
fail with Status 21 - Socket Open Error. Re-runs are generally successful.
I'd say about 30% of all RMAN and MS-SQL backups are failing with this nightly,
and its not always the same database or dataset. I moved the jobs from a
media server to the master, and the issue still occurs leading me to believe
this is a master server issue. I've had a case open with Symantec all
week and they are definitely seeing errors when the Master goes to open
communications with the client to start the backup, but cannot determine why
(so far.)
Has anyone else ever run into this / have
any ideas? I'm neck deep in Windows registry at this point trying to
figure something out but I've got no joy so far. I've goggled and checked
Symantec's site but this doesn't seem to be a common issue.
