Enterprise Manager Control (EMCTL) is a command line utility installed with EM to administer or control the core components of Enterprise Manager Cloud Control, particularly Oracle Management Service (OMS) and Oracle Management Agent (Management Agent). The utility is available by default with every Enterprise Manager installation. To access the Oracle Enterprise Manager Console from a client browser, the dbconsole process needs to be running on the server. The dbconsole process is automatically started after installation.

 

Before Starting DBCONSOLE, Make sure to check your location. If your COUNTRY LOCATION is listed under TZAgentlist then you can directly start emctl start dbconsole but if your country is not listed under TZAgentlist then you need to follow the following steps. Before starting check the TZAgentlist name from following. My current location is ASIA/NEPAL which is not listed under TZAgenlist. Here is the command to check the TZAgent name list :-
