Timezone mismatch: The agentTZRegion value (Africa/Khartoum) in
does not match the current environment TZ setting(Africa/Khartoum).
The dbconsole cannot run with this mismatch.
If Africa/Khartoum is the correct timezone, set your timezone environment variable to Africa/Khartoum and repeat the 'emctl start dbconsole' operation.
If Africa/Khartoum 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.
