Hello All,
I work in a system , where a 3rd party tool will monitor Oracle. It is throwing some alerts with ORA-12154.

But I was able to connect to database using SQLPLUS from win NT ( Database is running on UNIX ). I did check all the logs Viz.. alert.log, listener.log... I coundn't see any errors realetd to ORA-12154.

but the 3rd party tool is still throwing the error messages . And It is happening for all instances on the UNIX machine.

dont know , how these errors are coming, May be some expert can help me out.

Thanks,
Madhu
