Hi Gurus
I'm getting a very strange problem. All of aa sudden i'm encoutered with this error both on the server and on the client sides also.and i'm still getting this. The strange part is we are having two machines with same OS and DB and the same setup, very thing quite similar. But we facing this error on only one machine, other is working fine, both are production machines.
Please look into the errors.
Our OS is linux 7.1 , Oracle 9.0.1.
All of a sudden i'm getting
"
ORA-12500: TNS:listener failed to start a dedicated server process" and kicked out of oracle. " This is on client side, either sqlplus session or TOAD.
and also, On server side, i'm getting this error.
[oracle@cmsprod1 41dbexport]$ sqlplus
SQL*Plus: Release 9.0.1.0.0 - Production on Mon Sep 2 00:47:32 2002
(c) Copyright 2001 Oracle Corporation. All rights reserved.
Enter user-name: devlcms
Enter password:
ERROR:
ORA-12547: TNS:lost contact
At this point of time, i'm also getting,
"[oracle@cmsprod1 41dbexport]$ exp help=y
Segmentation fault (core dumped)"
Any one can help me please. Our LD_LIBRARY_PATH is not set on both the machines. But one is working fine and the other is not.
Waiting for your reply,
Thanks in advance

Turn on Tracing for Listener and try to identify through generated files.
Are you using dedicated or shared server modes.
Maybe you are encountering problems from the client machine ( need re-istallation Oracle Soft. for instance ) or from the network line but its too early to decide , just turn on tracing and see.
Reboot the server and try to connect also from the faulty machine alone and see.
Good Luck

Pls do post the following details. sort_area_size, sort_area_retained_size, no. of sessions connected to Oracle at the time of error, your sga statistics, paging space, no. of processes connected to server at the tome of error. Pls check for the msgs in "errpt" (aix version, don't know about Linux) and post the details. This looks like more of OS level problem.

An don't forget linux kernel parameters.
It seems like problem with # of semaphores or # of OS procesess.
