DB Version:10.2.0.4


Hi,

I have recently upgraded a 9.2.0.7 database to 10.2.4. and OEM was configured manullay using emca. The installation went without any problem.
Now I am facing a problem with starting up DBconsole although the agent starts up successfully . Below are some evidences and logs.

Now when emdctl.trc is viewed the entire contains the two lines given above multiple times.
It does not contain anything different from the two lines given below which appears multiple times.

Please note that agentTZRegion in /oracle/M30/102_64/sapm30_M30/sysman/config/emd.properties is GMT which is supported in /oracle/M30/102_64/sysman/admin/nsupportedtzs.lst and env settings for TZ is also the same.

Moreover when I try to start the agent it starts up successfully

sapm30ram30 39> emctl start agent
Oracle Enterprise Manager 10g Database Control Release 10.2.0.4.0
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
Starting agent ... started.

But still Dbconsole fails to start .

TZ=GMT0
The above timezone is supported in /oracle/M30/102_64/sysman/admin/nsupportedtzs.lst and present in /oracle/M30/102_64/sapm30_M30/sysman/config/emd.properties as the value of agentTZRegion.


Please advice what needs to be done to resolve this.


Thanks and Regards
