Timezone mismatch: The agentTZRegion value (US/Pacific) in

/home/oracle/oracle/product/10.2.0/db_1/localhost.localdomain_orclsid/sysman/config/emd.properties

does not match the current environment TZ setting(PRC).

The dbconsole cannot run with this mismatch.

If US/Pacific is the correct timezone, set your timezone environment variable to US/Pacific and repeat the 'emctl start dbconsole' operation.

If US/Pacific is not the correct timezone, make sure that the timezone in your environment is correct, and then run the following command in your local Oracle Home: 'emctl resetTZ agent'

The output of this command will include detailed instructions to follow, to correct the mismatch.
