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:

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

SQL*Plus: Release 9.2.0.4.0 - Production on Wed Feb 25 15:46:31 2004

ERROR:

Enter user-name:

SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus essex$ sqlplus '/ as sysdba'

SQL*Plus: Release 9.2.0.4.0 - Production on Wed Feb 25 15:46:57 2004

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
