hot bckup

Hi

I'm new to online bckup.

I have learned from manuals and know how to take hot bckup . And can any one tell how to restore the hot backup in case of any crash. A procedural way I'm expecting and checklist for hot backup. Is there any pitfall do you encounter in this hot bckup?

Thanx

This is an extremely broad question- first you can read the Oracle recovery guide which is mirrored in lots of places on the net.

I took several days and just played games on a test DB and tryed elliminating different files -- then recovering. If things didn't work I re-imported the test DB or re-created the DB.

Its a very different problem to recover a DBF file versus a CONTROL versus a ROLLBACK.

DON'T WAIT UNTILL DISASTER TO LEARN- Oracle is a bit wierd for recovery and it can't be explained in a nutshell. For instance, do you save your control file to trace ? That could make a big impact on the recovery of the control- but doesn't mean a thing if your bring back a tablespace. So how can someone tell you in a short little mail how to fix a complex DB when the variables are very wide.

My final conclusion was that if the DB wasn't too big that import/export was the best way to deal with "user" dataloss and errors.
