Sujatha, There is never, ever, ever, ever, a perfect time to use _allow_resetlogs_corruption. Never ever. The results of such an operation may not be known for hours, days or weeks. Look which datafile it is that needs recovery, system01.dbf... which means that if you force open the database you could (could) end up with an inconsistent data dictionary. It gives me the willies everytime someone suggests the use of this parameter. If your recovery strategy is such that you can not conveniently recover your database in cases like this, then it's time to seriously rethink the strategy.

It is in noarchivelog mode and is backed up cold. Unfortunately, something happened on Thursday and the database does not startup. I receive the following errors: SQL> startup ORACLE instance started. Total System Global Area 25410960 bytes Fixed Size 64912 bytes Variable Size 8388608 bytes Database Buffers 16777216 bytes Redo Buffers 180224 bytes Database mounted.

I know I have the cold backups ... but they have sent the tapes off site and it is going to take a while for the tapes to be located and sent to the data center and we need this catalog database up and running asap.
