[sparshav]

Hi All

One of our RMAN backup has been failing with error code 6. This status code is generic error and dba is also getting MML error on there side. We are using NBU 7.6.0.2 version on both master and client and backup target is DSSU.

some times backup gets completed and some time it fails. kindly find the dbclint logs which indicates the network issue.

Kindly help to get this fix and also advice if you need more information on the same.

We need entire dbclient log - not just extracts.

Please copy dbclient log to dbclient.txt and upload as File Attachment.

Check that the following logs are in place as well:

On master : bprd  (restart NBU after creating folder)

On media server: bptm and bpbrm
