Hi
We are facing problem at the time of on-line full database backup thru BRTOOLS. We are using "tape" as backup device and "dd" as backup command.With the same configuration offline backup is working OK.
The relevent error message is as follows : -

Hello,
This issue is described in note 948294, and pay attention to
You must mount all JFS2 filesystems containing Oracle datafiles (sapdata directories) with the mount -o cio option. This enforces a bypass of the filesysten cache for all programs.
Oracle redo log and control files are part of the Oracle datafiles. If these files are on JFS2 as well (origlogA, mirrlogA, origlogB, mirrlogB) the mount -o cio option must be used accordingly.

Hi,
I suppose the problem is with the tape. Please refer the note 540543 for details.
With regards
