I bet you also have listeners running...and possibly agents?

One other note of concern. It appears that the semaphores are too high
on this machine:

Shared Memory:
m 700 0x39699788 --rw-r-- -- oracle dba
m 701 0x9d8f0618 --rw-r-- -- oracle dba
Semaphores:
s 983040 0xe6f6fb58 --ra-r-- -- oracle dba
s 131073 0xe6f6fb59 --ra-r-- -- oracle dba
s 131074 0xe6f6fb5a --ra-r-- -- oracle dba
s 983043 0xa4a3ef00 --ra-r-- -- oracle dba
s 196612 0xa4a3ef01 --ra-r-- -- oracle dba
s 196613 0xa4a3ef02 --ra-r-- -- oracle dba

There are only 2 running Oracle databases so I was expected 2
semaphores. I am concerned we will have memory issues.

Guys,

Periodically, I see the following type of message in the alert.log
usually after a database open. We are running 9.2.0.4 and from what I
am seeing on Metalink this may be due to a bug during shutdown/startup
that isn 't resolved until 10i. It doesn 't appear to occur except during
shutdown/startup so I am not sure it is a problem. As I have often
found opening TAR 's to be frustrating I am not too concerned. Anyone
encounter this issue??


Errors in file /opt/oracle/admin/leprod/udump/leprod_ora_25892.trc:
ORA-07445 (See ORA-07445.ora-code.com): exception encountered: core dump [0000000100FAAFF8] [SIGSEGV]
[Addres
s not mapped to object] [0x000000004] [] []

Thanks,
Paula
