oracle database control

I just upgraded my OS to Windows 10. Now my Database Control doesn't "see" the database and won't allow me to login. It "thinks" the database is down and needs to be started. However, I can login to the database with SQL*Plus. The database is up and running.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Which Oracle database version is this about?

Unless there is some data in the repository that you cannot live without:  drop and recreate the repository.

emca -deconfig dbcontrol db -repos drop
emca -config dbcontrol db -repos create

I am on Windows 10 running  I had never gone to dbConsole since I upgraded to Windows 10.

It didn't let me get as far as you seem to have gotten.  I had to manually drop a few database things before the deconfig/drop worked:
drop user mgmt_view cascade;
drop user sysman cascade;
drop role mgmt_user;

Then I could use emca to drop the rest.

Even after the create I got an "unspecified" error the first time in.  I clicked on database (or whatever link was presented to me) and everything now looks fine.  I cannot reproduce the initial error so I cannot say what link was presented to me.

What about dropping and re-creating the repository?
JEBORKLUNDAuthor Commented:
I've solved the problem. Apparently, one or more of the users sys, system, sysman, and dbsnmp password had expired. I simply reset all of these users' password using SQL*Plus and the Database Control GUI interface now allows me in and I have full access again. I suspect that it was SYSMAN password was at the heart of the problem  but I reset all four.

Thank you to all who provided suggestions.
