Hemant - If you've got to rework your backup script anyway (and retest it), why not consider switching to RMAN at this time? In my experience, negligible interference with production during a hot backup.

[EMAIL PROTECTED] -----Original Message----- Sent: Tuesday, March 25, 2003 10:49 PM To: Multiple recipients of list ORACLE-L Some of my databases will be migrating to a SAN. Currently, I run hot backups to disk using the ALTER TABLESPACE <tbs> BEGIN BACKUP ; host cp <file> <target>; ALTER TABLESPACE <tbs> END BACKUP On a SAN, where the vendor promises server-less backups using Snapshots, I guess I would have to issue the commands : ALTER TABLESPACE <tbs1> BEGIN BACKUP .. .. ALTER TABLESPACE <tbsN> BEGIN BACKUP ALTER SYSTEM SUSPEND ....> take a "snapshot" ALTER SYSTEM RESUME ALTER TABLESPACE <tbs1> END BACKUP .. .. ALTER TABLESPACE <tbsN> END BACKUP Would that be right ? What are real-world experiences [bugs / time required for the SUSPEND/RESUME, actually flushing all I/O to the disks] ? The SAN will be a Hitachi 9970 sold by Sun. The databases will be 8.1.7 32-bit / 64-bit on Solaris 8.
