RMAN Failure

[simon peter wickham_1]

Hi
I have just set RMAN and up on our enviroment and all works fine when I do a backup to disk

Example Test :-
RMAN> run {
2> allocate channel LOCAL_DISK type disk format '/tmp/backup_ctrl.bak';
3> backup current controlfile; }

The problem is when using the backup software CommVault I get the following error can anyone advise me.

Error Message :-
connected to recovery catalog database

Hi,

do you want to do backup to disk or tape ?

You test script is performing backup to disk
but you second script to tape device - is this correct ?

If you want to backup database to tape you have to integrate CommVault software with oracle.
You must have correct libobk.sl in ORACLE_HOME/lib directory ?

Hi

Thanks for touching on this I should have stated to prove that RMAN worked I did the test to tape, but the failure notice is when I try to backup to tape.

Thanks,
Simon

hi simon,

RMAN on it's own will only backup to disk. If you want to backup directly to tape, you will need a media manager installed and configured.
