Oracle RMAN error: no channel allocated for maintenance (of an appropriate type)

Hello,

 

we are running DP9.05 and since recently we get an error on the Oralce backups:

 

RMAN-06091: no channel allocated for maintenance (of an appropriate type)

 

The advice from Oracle is:

1) Move all maintenance commands into separate RUN{} or outside RUN{} block and explicitly allocate required channels (DISK and/or TAPE) if RMAN needs to operate on backup files residing on both device types.

 

But all the allocate channel outside of run{} is truncated by DP.

Any idea how to fix that would be well appreciated.

Hello @yavor_paunov

If your DBA can create the script, DP allows you to modify it in the backup specification to be used. 

Maybe you can try to test that way.

Hello @yavor_paunov,

You can only have one run statement in a backup spec. You may find this link helpful.

Use Oracle RMAN with Data Protector

Re: Oracle RMAN error: no channel allocated for maintenance (of an appropriate type)

Hello,

Had the same issue. In my case backups worked, however at the archive log delete phase we received these messages with "no channel allocated for maintenance" when the logs should be deleted (after backup occurred). We end up altering the RMAN script in DP to not delete logs after backup, but we added a post backup script using proper parameters to delete the logs.
