Thanks Jayaseelan and Sambavan: I am explaining my situation once again. Please let me know if you know more details..

Yes.. I did create the OMS on the client side, since when the OEM installer created it had the host name as "my computer name" and also I saw the service on the NT services.

The Installer identified the db on Aix and created a TS on the box. A new user is created "sysman/oem_temp" on the db as well. On the workstation I have only the client. I configured my tnsnames.ora, mimiced the connection from client to server and as well started lsnrctl dbsnmp. I was able to discover the node successfully when I gave the IP address. I tried accessing the box after I enter the GUI where it shows me the names of the databases within categories like listeners, instances etc., and over there it gives me ora-12545 error..

When I did a reboot, even the services failed to start and now it gives vtk-1000 error. Either I resolve or install again my OEM on the workstation..

Where am I going wrong ??

What else can I do ??

My goal is to have OEM setup and usable by users without having to have local databases.. But obviously it implies they should have OMS on their workstations, right??

Thanks, ST
