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.
