Robert,

Ask the DBA if the Database is stuck in "Backup Mode". They will know what I mean.

Thank you.

Just spoke w/ 1 of the DBAs. We are doing A hot backup and the database should not be in "Backup Mode" at the time of Hot backup. It is also doing some backup be for it fail as noted in the Output provided.

If the database is stuck in mid streamd during the backup you will get these kind of errors that you getting. If you try another backup of the database while its still in backup mode you get these kind of error.

Is the reagular backups of this server working correctly? Is it only the Oracle thats failing?

Only the oracle backup is having an issue. I just got off a group call on this and looks like we might change the TcpWaitDelay registry entry and up Logging to see if we get better output to trouble shoot with Symantec Support if we have no luck via forums and our knowledge base.

I'll still have them check database mode.
