WHY, your are telling NO, i think we can restore upto 15-07-09
he having backup upto 30-07-09, backup means all transaction uptp 30-07-09.

example, if he have backup upto 10-07-09 and dont have archive log, in this case if he wants restore up to 15-07-09 is difficult, bcause he having backup uptp 10-07-09 and he dont have archivelog

Then show us EXACTLY how. Because I think it's not possible, too.

Are you saying you do NOT have backups of the archivelogs, BUT you do actually have the archivelogs between 01-07-09 and 15-07-09 available?

if we have backup upto 30-07-09, then we want restore upto 15-07-09, we can do that by

RECOVER DATABASE UNTIL TIME '2009-07-15:12:00:00'

am i correct???

You would be correct if there had been a backup of the archive logs.

But since the person with the problem clearly stated "no backup of archivelogs", you can only restore a backup at the time of the level 0 backups. So either 01-07-09 OR 30-07-09, not anything in between.

thanks all for the replies .

As i dont have any test system to try to restore to a point which is earlier than a level 0 backup taken.I was wondering if someone has actually faced or done this before..If anybody wants to try to test it..please do post your findings..it would be grateful to all..

Since Oracle can be installed on any PC or laptop, I find this "excuse" to be nothing more than a total cop-out.
You have no legitimate reason not to have a functioning Oracle in front of you whenever you are online.
You don't need multiple GB of storage to run most applications.
RMAN can backup empty or sparse tables with the same commands that are used in Production.

If you want to restore a particular date/time in past - you need to have backups taken prior to that data/time and all archived logs leading to that date and time since the backup initiated.

Based on the details you have provided if you want to restore prior to Jul 15, then you need to have backups performed before that date and time and all the archived logs since the backup initiated.

If you only have backups that you have documented then you cannot restore to the point you are hoping to restore to.
