Slow restore on v8.1 for Solaris 8

I'm restoring a 14 gig db into a new database. The restore process
took 3 hours to complete. How can I make the restore faster and How
can I determine the progress of the restore.

thanks

You can tune the utilheapsz, restbufsz ...

The biggest bottleneck to the best of my knowledge is your I/o and if the backup is on a network, then your network bandwidth may have limitations ...

... to know the progress, I rely on 'get snapshot for tablespaces' and sometimes 'direct reads' in the database snapshot ...

They may not show you the completed percentage, but atleast you know, your restore is working and where you stand ...

If you are using vendor storage systems (like TSM), you can use their facility to view the progress ...

For eg, if you use tsm , dsmadmc command followed by 'q sess' will help to know how much data is read from the storage system
