corrupted Oracle 11g database At a client site with a development Oracle 11.2.0.3/linux DB

power outage and crash - no archivelog mode - no backups - Don't know how this was even running

Basic plan:

alter database datafile 2 offline drop;
alter database datafile 11 offline drop; 
recover database ; 
export/import
rebuild DB


Don't care about sysaux, however, I hope to keep whatever is in datafile 11.

I was hoping to force the DB open even with datafile 11 in a bad state.

Oracle says any hidden parameters will not help due to very old SCNs.

Have you faced this situation and successfully recovered the data?
For anyone who wants to know how this was resovled...

Bobby Durrett was correct, Oracle does have the ability to pull data from blocks.

I contacted Oracle ACS.  They sent a top consultant and using the Data UnLoader tool (DUL), which by the way is not their product, were able to extract data from the blocks that survived the corruption.

Bascially you configure the tool with a few parameters and identify the datafiles of interest.  It helps a lot if the system data file is present.  You can tell it to create SQL*Loader or dmp files.  It will skip any block that is corrupt and move on to the next block.  The datafiles are read cold so no need to mount or create a new instance or any such thing.

Caveat:
All you get is table DDL and data.  No users, contraints, FK so your are not recovering the database, just the data.

It works beautifully - on any block not corrupted!
