OEM stopped working

Hi,

I have a Test-RAC-Sytem (release 11.2.0.3 ) on 2 Linux RH 5.4/X86-64 and managed is until one week ago with a working Oracle Enterprise Manager (OEM/IE9),
Today I tried to start the OEM again! It worked no more! No information of the cluster and database were shown (no host, nothing)

At the top right corner of the browser the notification :"certificate error" is displayed.

The EM Daemon is running!
[oracle@stb ~]$ emctl status dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0
Copyright (c) 1996, 2011 Oracle Corporation.  All rights reserved.
https://dwh:1158/em/console/aboutApplication
EM Daemon is running.
------------------------------------------------------------------
Logs are generated in directory /u01/app/oracle/product/11.2.0.3/dbhome_1/stb_rac/sysman/log
I am clueless! Can anyone help me?

regards

Notes:
I have a standalone DB on one node of this RAC-Systen and can control this database with the OEM, although the error "certiface error" is shown.

    did you allow the certificate in your browser? maybe something on your security has changed.,

    My answer: I changed nothing! the system was in the last days down!

    Now I can connect securely the oem over port 1158, but no details were displayed! It showed only:
    Cluster Database : rac 
    
    The database status is currently unavailable. It is possible that the database is in mount or nomount state. 
    Click 'Startup' to obtain the current status and open the database. If the database cannot be opened, click 'Perform Recovery' to perform an appropriate recovery operation. 
    I tried to start the database "rac" up. But it ran already !

    In "cluster"-part I cannot open the tabs "home", "Targets", "Interconnects" and "Topology"

    try changing to the directory where you run the[url http://docs.oracle.com/cd/E11857_01/em.111/e16790/emctl.htm#BABEFBDI] agent, then:
    ./emctl status agent
    Look at the dates of the log files in all directories you can find with log files in them. You probably have errors in there.

    Be careful about blindly following MOS notes, they can lead you down the garden path to insanity. At least understand the commands they say before you run them.
