Two days ago we had a problem with our san that crashed a few of our
databases. I was told failed drives but I don't know how to validate that
and communication on the issue has been sketchy.

Everything seems to be fine except for one database. It is a reporting
database that contains replicated data from a remote site.
The refresh of the materialized views is scheduled for every 2 hours. When
the job runs we receive a 600 error with the following arguments:
ORA-00600: internal error code, arguments: [6731], [1], [0], [3], [], [],
[], []
ORA-00600: internal error code, arguments: [17090], [], [], [], [], [], [],
ORA-12012: error on auto execute of job 41
ORA-12008: error in snapshot refresh path

And it gets worse. I tried shutting down the database with 'shutdown
immediate'...nothing. 'Shutdown abort'..ok. Startup returns:

SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup
ORACLE instance started.
Total System Global Area 87521768 bytes
Fixed Size 104936 bytes
Variable Size 38092800 bytes
Database Buffers 49152000 bytes
Redo Buffers 172032 bytes
ORA-01102: cannot mount database in EXCLUSIVE mode

I then shutdown abort and ps -ef | grep SID. There are several processes
out there. I try to kill -9 them but they won't go away.

Sysadmins can't kill the processes either. We reboot the machine, processes
are gone. Startup the database. Run the refresh.....it 'hangs' for hours
and hours. Shutdown the database after trying to figure out what is going
on (possibly rollback from crash?...but no) and the try to restart but
receive the same unable to mount error with associated processes. The other
weird thing is that the majority of datafiles in the database have not been
touched or updated by oracle in some time.

I don't know what to do.

I opened a tar from oracle but have received no help so far.
Anyone have any ideas?
