RE: Oracle hangs on startup (9.2 on Win2000)

One other piece of information: when I try using Oracle Enterprise = Manager to connect to the database (using SYS as SYSDBA), I go to the = "General" tab on Instance/Configuration, and this shows the database in = a "down" state (red traffic light). I then try to open the database, = click Apply, and the "Starting up the database" step fails with the = error:

"ORA-03113: end-of-file on communication channel"

Does this shed any more light on the possible cause of the problem?

Subject: Oracle hangs on startup (9.2 on Win2000)

We're getting a very strange problem with very few symptoms to work =3D from.

It's our policy to take cold backups of our Oracle 9.2 database, which =
=3D

runs on a Win2000 server. Consequently, the Veritas backup job first =3D shuts down Agent, Listener and database, then the backup runs, then the =
=3D

job restarts the database, Listener and Agent.

All the above has worked perfectly well for several months. Until last =
=3D

night... when someone tried to connect to the database, it was apparent =
=3D

that the database was still down. I looked in the event log and found =
=3D

the following:

• - - - - Dump file d:\orant\admin\dlib\bdump\alert_dlib.log Tue Nov 02 10:44:42 2004 ORACLE V9.2.0.2.1 - Production vsnsta=3D3D0 vsnsql=3D3D12 vsnxtr=3D3D3 Windows 2000 Version 5.0 Service Pack 4, CPU type 586 Tue Nov 02 10:44:42 2004 Starting ORACLE instance (normal)
• - - - -

These were the last lines in the event log. It looks as though the =3D startup of Oracle simply "hung". No error messages, no trace files =3D generated. Nothing, just hanging there.

We tried stopping and restarting the database service, with exactly the =
=3D

same result (the above is pasted from this later attempt, in fact). We =
=3D

tried rebooting the server. Same result. The listener log indicates no =
=3D

problems. But every attempt to startup the database gives the above =3D result.

Any ideas, please?
