RE: RMAN backup with MULTIPLE CHANNELS ......

Mandar,

Thanks for your reply. Iam in the process of checking with my Netbackup Administrator about the parameter: Max_jobs_per_client. After seeing your E-Mail, I too looked into the online manual and it seems the value should be = Number of streams X No.Of Classes. In my case No.Of classes equals to 1, and since I would like to use 3 tape drives thru 3 channels, I think Max_Jobs_per_client must be set to 3. I forwarded the info to my Netbackup Admin.

Thanks for the info.

also check "Maximum Jobs per client".
you will find this setting in the Netbackup preferences window (Netbackup Java console).
