I have installed Fabric Manager Server v3.2(2c) using the Oracle DB option. Backup of this DB can be done in either Online (ARCHIVELOG mode) or offline (NOARCHIVELOG mode).
In one of the ccokbooks i found the Oracle DB holds inventory, fabric configuration and states of the ports.
How critical is a backup of this DB if i'm not using Performance Manager? (I believe PM stats are also held in this DB). If this DB becomes corrupted what are the consequences?
I assume you are not using the SME Storage Media Encryption feature? If not, and you are not collecting performance data, there would be no consequence if the DB got corrupted. You might have to re-install Fabric Manager. It would not affect anything in the running fabric, as all zoning, and configuration data is maintained in the MDS switches.
If you are using SME for encrypting tapes, then that's a whole other story. If the DB is being used to store tape encryption keys, and it gets corrupted, then you loose the ability to decrypt the tapes.
Hope this helps,
