Hi All,
I'm running oracle 9.0.1 on Linux 7.1 . For the past one week , i'm getting a strange error when i'm trying to connect to oracle with SQLPLUS command.

[oracle@cmsprod1 oracle]$ sqlplus

SQL*Plus: Release 9.0.1.0.0 - Production on Fri Aug 23 12:39:55 2002

SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

I looked for LD_LIBRARY_PATH first, it was not set, then i edited in my .bash_profile as
LD_LIBRARY_PATH=$ORACLE_HOME/lib and ran my bash_profile from oracle user. and again when i say, 'env' , this parameter was set.

But still, even after doing all these, i'm getting the same old error. Please suggest me .


Thanks
