OEM dbconsole Start Failed

Problem The dbconsole was working fine before the timezone setting (DST) was changed, but after the timezone was changed it stopped working.

solution When OEM dbconsole is started the agent timezone setting is recorded in the emd.properties. Everytime you start the dbconsole it will check the current timezone setting with the value in the emd.properties. When the two values mismatch the dbconsole will not start. We have to update the setting for the agent timezone.

To update follow the steps given below.

Check the timezone setting in /etc/environment.
The setting for TZ must be one of the supported timezone setting listed in the ORACLE_HOME/sysman/admin/supportedtzs.lst file


$ export ORACLE_SID=gcprod1
$ emctl config agent updateTZ
The output could be a different setting from the TZ in /etc/environment.

$ emctl stop dbconsole

$ emctl config agent updateTZ

$ emctl start dbconsole

Starting and Stopping Database Control

Database control is the standalone management console. Each database has its own database control console. It requires the dbconsole process to be started prior to use.

To start the dbconsole process

$ emctl start dbconsole

To stop the dbconsole process

$ emctl stop dbconsole

To view the dbconsole process status

$ emctl status dbconsole

Thanks
