OEM Scheduled Jobs

I am not able to run any jobs through OEM 2.2. Everything seems configured correctly. I am using a management server and all nodes and databases are recognized. I am trying to run a simple SQL*Plus test script through OEM Jobs but I am getting this error:

SP-0306: Invalid option.

It seems that there is a problem with the SQL*Plus logon. Any advice would be appreciated. Thanks.

unix or nt

check logs

try run the script from a sqlplus session to make sure the script is correct

It is not the script. It seems to be a problem with getting connected through SQL*Plus by the way of OEM. I can't even use this: select sysdate from dual;

I am using win2000, the management server is on the same machine, and I am connected to a UNIX (DYNIX/PTX)database that is version 8.1.6

thanks

have you checked the logs?
