Possible to reinstall Enterprise Manager 11gr2 ?

[Audrey A Lee]

Hello people,

I downloaded 11gr2 and installed it on my ubuntu box.

The install was smooth.

At the end I connected to Enterprise Manager (EM) and it seemed to be
working okay.

Then I bounced the database.

EM went haywire.

I shutdown EM.

I tried to start it up.

It seems sick.

I see a lot of errors in the sysman log.

This is just a training DB. I don't care about any of the data in
it.

So I'm willing to tinker with it quite a bit and toss it in the trash
if need-be.

Here is my question:

-Does EM (11gr2) have a reset-button or recipe to reinstall it or re-
initialize it?
