How frequently you get NetBackup MML errors (ORA-19511)?
We got Symantec NetBackup servers and doing rman backups directly to tapes. This generally works, however almost every day we get MML errors.
We got quite sophisticated architecture and got a lot of stuff backing up to tapes besides oracle. I dont really want to discuss why MML happening, this is longstanding issue, the question here is how normal it is? Is it ok to have several MML per day in a busy environments? Has anyone observed this as well in your experience?
