I have inherited an instance of Oracle 8.1.7 on Sun Ultra II runnin Solaris 5.8.

when I try to run sqlplus from the unix prompt (the server) I get the ORA-00600 internal error code with a bunch of %s arguments.
But when I access the database from sqlplus on my client (Win 98 m/c) I am able to connect and work.

when I run the status command in lsnrctl, I get "TNS-01150- address of listner is incorrect" and "NL-00305 - the specified path does not exist "errors.

Any help would be very appreciated.

Thanks,
Ashu
