RE: Oracle hangs on startup (9.2 on Win2000)

Paul Vincent


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 =

"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

It's our policy to take cold backups of our Oracle 9.2 database, which =
runs on a Win2000 server. Consequently, the Veritas backup job first =3D
shuts down Agent, Listener and database, then the backup runs, then the =
job restarts the database, Listener and Agent.

All the above has worked perfectly well for several months. Until last =
night... when someone tried to connect to the database, it was apparent =
that the database was still down. I looked in the event log and found =
the following:

- - - - -
Dump file d:\orant\admin\dlib\bdump\alert_dlib.log
Tue Nov 02 10:44:42 2004
ORACLE V9. - 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 =
same result (the above is pasted from this later attempt, in fact). We =
tried rebooting the server. Same result. The listener log indicates no =
problems. But every attempt to startup the database gives the above =3D

Any ideas, please?
