Hi,
Our oracle guys are receiving following errors while tryng to restore data from tape.Would some one please shed some lights?

RMAN> run {
allocate channel DB_TS_T12 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/qr/CG_backup/TDPO/tdpo.opt)';
allocate channel DB_TS_T22 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/qr/CG_backup/TDPO/tdpo.opt)';

I see this thread has been posted already 3 days ago, is this still an issue ?

In that cqse : Hard to tell what the problem is when there is no information on how the backups are taken ?
-> Do you have a backup software interfacing with RMAN
-> Do you run native RMAN backups
-> What are the backup commands.
-> How do you connect to the database from RMAN

And I further suggest you take this issue to Oracle, since they probably have more knowledge and expirience about possible issues.
