Hi all

I have done no changes, and until yesterday EM worked just fine on my 10g install on XP, but now it refuses to service users...

When I start the service everything seems ok:
D:\Documents and Settings\XXXXXXXX>emctl start dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.2.0.1.0

Starting Oracle Enterprise Manager 10g Database Control ...The OracleDBConsoleocp10g service is starting....
..............................................................................
The OracleDBConsoleocp10g service was started successfully.

Cannot connect, so I check emagent.trc. The last lines look like this:

You trying to connect as NORMAL user?
Do you have ENABLE PROFILES?
Check the SESSIONS_PER_USER limit parameter of profile.
How many sessions you can open as a NORMAL user through SQL PLUS?
Post EMCTL STATUS?

Yes.

I tried connecting with system a second time through sqlplus, and it failed. Too many concurrent users. So I set resource_limit=false, and now I could connect a second sqlplus with the same user. This did not solve the problem with enterprise manager, though.

Don't know. This is just a testserver I use for certification tracks.

Hi,
Reconfigure your em repository.

1. 

E:\>set oracle_sid=db01

2.  

 DECLARE
 CURSOR c1 IS
 SELECT owner, synonym_name name
 FROM dba_synonyms
 WHERE table_owner = 'SYSMAN';

 BEGIN
 FOR r1 IN c1
 LOOP
 IF r1.owner = 'PUBLIC' THEN
 EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
 ELSE
 EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
 END IF;
 END LOOP;
 END;


PL/SQL procedure successfully completed.

DROP ROLE mgmt_user;

Role dropped.

DROP user mgmt_view cascade;

User dropped.

DROP user sysman cascade;

User dropped.

3. 

E:\>emca

I restarted the services again, and now it worked!

Thanks for the help.
