How about cleaning up Shared memory segments using ipcs
and (ipcrm -s <shared mem process> for unix and ipcrm sem <shared mem process> for linux).

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. SQL> shutdown immediate ORA-24324: service handle not initialized ORA-24323: value not allowed ORA-00020: maximum number of processes (%s) exceeded
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
