How to configure Offline backup, R3, 4.71, Oracle 9.2.0.7, SunSolaris

Hi all,

We have Daily online backup at night. We need to change the hard disks so I need to to take offline backup of all including file systems, datafiles etc (how to disable online backup and what command to use for offline backup).

Also after changing the hard disks I need to restore this offline backup (again need to configure regular online backup,)

Should I need to reconfigure all background jobs, Printers etc

No changes in SID & Host name.

Can any one help me in this regards. . . any documents I can get. . . .

Advance Thanks

Regards
