Timezone mismatch: The agenttzregion value (US/Eastern) in
/U01/APP/Oracle/product/10.2.0/db_1/localhost. localdomain_shym/sysman/config/EMD. Properties
Does not match the current environment TZ setting (PRC ).
The dbconsole cannot run with this mismatch.

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

[Solution to incorrect time zone error prompt]

[Oracle @ localhost bin] $ emctl config agent gettz
[Oracle @ localhost bin] $ emctl config agent updatetz
[Oracle @ localhost bin] $ emctl start agent
[Oracle @ localhost bin] $ emctl start dbconsole
