please help me to overcome this error.
Thanks in advance.

I just issued the below command to recreate the repository and everything seems to be working fine

Thanks for your help.

emca -config dbcontrol db -repos recreate

(Please correct me if I’m wrong,) I think if you use the above command, you don’t need to issue the drop repository command as Oracle will erase all the settings and recreate them for you.

E.g.

C:\>emca -config dbcontrol db -repos recreate

Cheers,

Thank you for the information and instructions. However, since I am a newbie at this, I’d like to ask you a silly question. By dropping the repository, is there any chance that it will affect the database itself? I.e. I have a few databases that I cannot afford to lose, and it seems that I have set up some parameters in the OEM incorrectly. I’d like to reconfigure the OEM without affecting the database itself, and I hope the steps that you posted above is the solution (please correct me if I’m wrong). Thanks a lot for your help and looking forward to hear from you soon. Once again, nice website Andre, and thanks for sharing all the very informative knowledge
