Problem with Oracle 10g R2 on CentOS 5.0
Hello friends,
I installed Oracle 10g R2 on CentOS 5.0. Now I was having problem starting the listener:
[oracle@nebuchadnezzar admin]$ lsnrctl start
LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 17-JUL-2007 00:14:52

As somebody suggested to me, I commented out the IPC line from my listener.ora and got the following result:
[oracle@nebuchadnezzar admin]$ lsnrctl start
