Netbackup RMAN Multistreamed backup
Netbackup 7.5.0.4
Oracle 10g
I have taken rman backup with 4 channels.
During the restoration also I have allocated 4 channels.
4 restore jobs got started but only one is reading the data...

hi,
you are correct, only one job can use one tape, multiple jobs can not use the same tape at same time.
paralle restore jobs works effectively when you have the backup data in different Tapes or in Diks.
if the data is same tape, even though paraller restore jobs started, they will run one by one.. because , only one job can use one tape.
comming to RMAN backup with Multistream, that is one that you can elable in RMAN script,currently you are using 4 channels(streams), if you want to increase change the setting in RMAN scripts.
and make sure you have enough (tape drive or disk) rescources avalible to avoide the queued jobs.
