Re: RMAN error (ORA-19502)

Hey Andrey,

We too are facing the exact situation when we are backing up our 1.7 TB
datawarehouse database using VERITAS netbackup, Oracle v9R2 (9205) on HP
Superdome.
Veritas saying that this is due to the connection/communication drop from
network of one of the channel specified.
We tried even with 1 channel, but, the result is the same. However, the case
is still open with Veritas support and we are going to apply few HP patches
and Veritas patchs.
In our case, the only change was that we move few of our datafiles to a new
storage. However, this should not be the sure stopper.
We are going to shutdown the sever, luckly we got downtime and try the
backup again. This started all of sudden without any positive reasons.
I will update this thread if we solve the problem.

The script backups datafiles to tapes using VERITAS NetBackup for Oracle -
Release 5.1

The channels are allocated using the command:

ALLOCATE CHANNEL ch<n> TYPE 'SBT_TAPE' trace=2;

trace=2 was added to get additional info



The tracing generates trace files with the error:



entering sbterror on line 2692

return from sbterror on line 2703

SKGFQ OSD: Error in function sbtwrite2 on line 1034

entering sbterror on line 2692

return from sbterror on line 2703

SKGFQ OSD: Error in function sbtclose2 on line 1304





Does anybody know something about the problem or how to reveal it?



Thank you very much,

Andrey Goryunov
