Hi:

In 8i, when I got the above error, I always could launch svrmgrl, connected
as intenal and bounce the DB. Now in 9i without svrmgrl, how do we bounce
the db if we have the above error?

I did the following test on a 9204 db on Solaris 9:

1. I set up processes=12 in init.ora, and started the db, everything is OK.
ps -ef|grep ora_ gave me:

oracle 9209 1 0 13:59:20 ? 0:00 ora_pmon_YPD
oracle 9217 1 0 13:59:21 ? 0:01 ora_smon_YPD
oracle 9211 1 0 13:59:20 ? 0:00 ora_dbw0_YPD
oracle 14801 14800 0 15:44:56 pts/3 0:00 ps -ef
oracle 9223 1 0 13:59:21 ? 0:01 ora_qmn0_YPD
oracle 14800 14787 0 15:44:56 pts/3 0:00 grep oracle
oracle 9215 1 0 13:59:21 ? 0:02 ora_ckpt_YPD
oracle 9219 1 0 13:59:21 ? 0:00 ora_reco_YPD
oracle 9213 1 0 13:59:21 ? 0:02 ora_lgwr_YPD
oracle 9221 1 0 13:59:21 ? 0:00 ora_cjq0_YPD

2. I opened two seperated sql sessions, connected as regular user. No
problem. So I left them idle.

3. When I tried the 3rd session, I got

essex$ sqlplus user/password

Connected.

I can not shut down the DB. The other two sessions are still working as
normal. I don 't want to do "kill -9 " to another sqlplus connection if I
don 't have to. Do I have another choice if I want to bounce the db?

TIA.

Guang
