Home -> Community -> Mailing Lists -> Oracle-L -> RE: RMAN error (ORA-19502)
Hi All,
the parameter BACKUP_TAPE_IO_SLAVES was set to TRUE
(TAPE_ASYNCH_IO set to TRUE as well)
and LARGE_POOL_SIZE was changed to ~170Mb (10 channels operate)
but it did not help. The backup is still failing with the same error.Do you have any ideas what else might be tuned?
Regards,
Andrey Goryunov

Hello, thank you for your information. We put the file on a client side (it was not there) with the same value (262144)as on a server side, but, unfortunately, it did not help. The backup failed with the same error during channel release. At the same time, the database has BACKUP_TAPE_IO_SLAVES = FALSE.I am planning to change it to TRUE this weekend.Will see if it helps. Thanks,Andrey Goryunov

We have resolved the issue. Bouncing database server doesn't help neither. What changes we did was that we looked into the value of NET_BUFFER_SZ file on the client (database host) and on the netbackup server side. The value in the file is different, in fact, client file has higher value than the server file value. Upon synchronizing client value with Server side file value resolved our issue and backup started running without any problems.
I hope this would give you some hint to resolve your probelm as well.

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. On 5/29/07, Andrey Goryunov <goryunov_at_hotmail.com> wrote:
