Working on Oracle 8i with OS as Unix Solaris 8.0.

Could anyone out there improve on the topic:Improve restoration speed on RMAN Backup.

Scenario:It takes approx 4 hours to backup datas on RMAN with around 200 to 300GB size of Database and around 2 to 3 Hours for restoration from Backup.

In our case we are allocating 4 channels to read from one single tape device in case of RMAN but still the restoration speed goes beyond 12 Hours!!!

Did anyone experience on this topic :How to improve RMAN backup Restoration speed.

Thank You for your time.

Regards,

Amit.
Restoration from tape is usually slow. And i don't think making more than one channel on a tape drive will help, because at one time only one location can be read on a tape(i.e. the place where the head is on the tape), its not like a hard disk where multiple files can be read at once.
