We are running the same database version and OS version. This same problem just recently started happening on one of our databases. We do the folowing

Shutdown immediate;
Startup restrict;
Shutdown;

The shutdown immediate was fine. However, the normal shutdown was generating the 1013 error. From what I could tell, a user with dba rights was connecting while the database was in restrict mode. I modified the script so that it locks that user's account prior to the first shutdown. This seems to have fixed my problem.

However, I'm not answering your question. I'm not sure what timeout value is used. Are these sessions executing some long running SQL commands? Can they be rescheduled to run at another time? Years ago, I had an instructer tell me that for backups, just do the following:

alter system checkpoint;
shutdown abort;
Startup restrict;
Shutdown;

While this definitely brings the database down, I never really felt comfortable doing this. You might just want to kill active processes before you start your backup.

Subject: sqlplus shutdown "time-out"

Hi all,

9.2.0.5.0 on Aix 5L.
Before our cold RMAN backups, we shutdown and startup the instances as foll=
ows:

sqlplus '/ as sysdba' <<EOD
shutdown immediate
startup
shutdown immediate
startup mount
EOD Sometimes both shutdowns seem to time-out automatically (certainly while Oracle is busy rolling back some huge transactions):

=3D=3D> Beginning consistent instance shutdown and mount: Thu Apr 14 01:35:02 DFT 2005 SQL*Plus: Release 9.2.0.5.0 - Production on Thu Apr 14 01:35:02 2005

Connected to:

SQL> ORA-01013: user requested cancel of current operation

With the Partitioning, OLAP and Oracle Data Mining options JServer Release 9.2.0.5.0 - Production =3D=3D> Ended consistent instance shutdown and mount: Thu Apr 14 03:37:55 D= FT 2005

Both "user requested cancel" aren't human actions and it seems that both shutdowns time-out after 1 hour.

What might be the cause of thes time-outs giving that sql*net is not involved and that sys's profile is "default" (idle_time=3Dunlimited). I can't find any relevant time-out parameter for sqlplus (only for isqlplus).

TIA,
Jerome
