Oracle 11.2.0.3

OS: Linux

1. How to run "restore database validate" using four channels. I was running the following and it was taking same time as backup itself. our databas is 100TB and it took 60 hours to run this backup and validate restore would have been taken this long but killed it half way.

ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE 'SBT_TAPE' connect 'sys/password@psprod';

RESTORE DATABASE VALIDATE;

exit;

2. I understand that RMAN RESTORE VALIDATE command check and verify the integrity of the backups which are stored on tapes but why does it take such a long time,

Thank you.

Howdy, Stranger!
