RE: 9i : ORA-00020: maximum number of processes (%s) exceeded

Replies:
Well, I set up processes = 12 just to do my testing. The regular value is
150 (I think it is default). I don't want to open 140 or so sessions for my
testing.

We occuasionally had some adhoc scripts running against 8i db that locked
certain table and the other sessions would start to pile up after that. I
had to bounce the db. I am wondering if thers is some other way to log into
db in 9i without doing the session killing. I guess this might be one reason
that we would stay in 8i for a while.

Why would you set processes = 12? Are you trying to OFF you databse? Was
this some kind of a bad experiment? What worked for 8i doesn't necessarily
work for 9i. Use the kill command and just kill the SQL*Plus sessions, log
in as SYSDBA and shutdown the DB, and call it a day. Or use "kill" to kill
the database. Dealer's choice.

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

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
