hi Chris,

is your db ok now?

I had same (similar) problem long ago unix zombie processes got to = reboot (power off/on) Sun Solaris box, permission ok but when I tried to = "touch" a file in those mount point that contain datafile it was fail, = the reason is because my hardware (EMC) I/O Card problem. but I can see = those mount point when I do df -k, and ls -l can see the files and size.

Since you said the timestamp of those data files are freeze at certain = point...
why don't you try to create test file in those mount points log in as db = owner

good luck

Sinardy

Permissions are fine. Nothing has changed there.

I'm having the sysadmin run fuser now....but I believe it will only show = the
processes that will not go away. ..i'll post the results

Chris,

        Two things come to mind,

  1. What are the permissions on the database files? Has their ownership =3D and/or group changed?
  2. Try getting the sysadmins to run an fuser command on the files when =3D the database is known to be down.

8.1.7.2 on HP 11

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 = =3D
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. =3D20 The refresh of the materialized views is scheduled for every 2 hours. = =3D
When
the job runs we receive a 600 error with the following arguments: ORA-00600: internal error code, arguments: [6731], [1], [0], [3], [], = =3D
[],
[], []
ORA-00600: internal error code, arguments: [17090], [], [], [], [], [], = =3D
[],
[]
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 SQL> I then shutdown abort and ps -ef | grep SID. There are several =3D processes
out there. I try to kill -9 them but they won't go away. =3D20

Sysadmins can't kill the processes either. We reboot the machine, =3D processes
are gone. Startup the database. Run the refresh.....it 'hangs' for =3D hours
and hours. Shutdown the database after trying to figure out what is =3D 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 = =3D
other
weird thing is that the majority of datafiles in the database have not = =3D
been
touched or updated by oracle in some time. =3D20

I don't know what to do.

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

Thanks
chris
