We see this error in the RMAN output:

 Server Status:  Communication with the server has not been initiated or the server status has not been retrieved from the serve

Please ensure that the following log folders exist:

On client: dbclient (with 777 permission)

On master: bprd (NBU needs to be restarted to enable bprd log.)

On media server: bpbrm

Please copy logs to reflect process name (e.g. dbclient.txt) and post as File attachments.

Does the backup work on 1 channel instead of 4?

I Will post the logs in couple of hours.

PLease let me konw if u need any other logs.

IT is working on 2 channels and not working on other channels but none of the files were backed up.

We would normally ask for these logs;

From the Master/Media Server:
1. Bprd Log from Master
2. Bpbrm Log from Media
3. Bptm Log from Media
4. Run Bpclntcmd from both Master/Media and send me the outputs:
run /usr/openv/netbackup/bin/admincmd bpclntcmd -pn
run /usr/openv/netbackup/bin/admincmd bpclntcmd -hn client_hostname
run /usr/openv/netbackup/bin/admincmd bpclntcmd -ip <client_ip address>
5. bpconf file

From the Client:
1. Dbclient Log
2. Bphdb Log
3. Bpcd Log
4. user_ops/dbext/logs
5. Rman Script and Rman Output file
6. Run Bpclntcmd and send me the outputs:
run /usr/openv/netbackup/bin/admincmd bpclntcmd -pn
run /usr/openv/netbackup/bin/admincmd bpclntcmd -self
run /usr/openv/netbackup/bin/admincmd bpclntcmd -hn Master server
run /usr/openv/netbackup/bin/admincmd bpclntcmd -ip <master_ip address>
7. Directory listing:
/usr/openv/netbackup/logs/user_ops
/usr/openv/netbackup/logs/user_ops/dbext/logs

Where are you seeing the status 0, in Activity Monitor?

If so, do you see multiple jobs, parent job and child jobs?

Thanks for the inputs the issue is resolved.
