Oracle Standby - Listener could not authe nticate the user

[vijaya sharma]

lsnrctl services standby_database

This results in an error which says that:

TNS-01189:The listener could not authenticate the user.

Note: The listener and the services are properly configured for the standby and the primary database, which are configured on CentOS and Oracle 10g.

Any idea what could be the problem.

Thanks,
Vijay

This error is received on the primary database.

while the services for the standby and the primary databases are working perfect on the standby database.The ports at which they listen are also configured properly.There does not seem to be any firewall issue because i am able to ping and tnsping to the primary and standby to and fro. also the remote logging and file transfer works on both the systems.

Thanks

Vijay
