Hello Chandra,

does your oracle user have access to the file /etc/hosts? Does this file contain a localhost entry?

Please check the permissions and the content of the file /etc/hosts.

shell> ls -la /etc/hosts
shell> cat /etc/hosts | grep -i localhost

This error is described in metalink note #315720.1.

Hi

I have gone through the metalink there we find that if execute slibclean command in root user it work but problem is still coming

Hi,

if slibclean solves the problem, it has to be shared library bound.

So a lib is loaded, that conflicts with the one the listener requires.

What user do you use to start the listener?

What is the value of the lib-environment variables?

- LIBPATH ?

- ORA_NLSxxxx (as many as you have set)

What version are you on?

Did you upgrade/patch Oracle recently? From which version.

Did you adapt tnsnames.ora and listener.ora.
