EM Console

1. Enterprise Manager console can be configured for single database i.e DB Console
This is used to manage single alone database.
2. EM Grid control is used to manage multiple databases centrally.

Starting and Stopping the Management Service

The relevant emctl commands for Linux are listed in the following table.

You must be in the OMS_HOME/bin directory to issue the emctl commands, where OMS_HOME is the Oracle Application Server home directory in which the Oracle Management Service is installed and deployed.

Note: To execute the opmnctl commands, you must be in the OMS_HOME/opmn/bin directory.

Table 7-1 Commands to Start and Stop Management Service

If you want to	Enter the following Command
Start the Management Service	emctl start oms
Stop the Management Service	emctl stop oms
Verify status of the Management Service	emctl status oms
Start all components of the Application Server, including the Management Service and WebCache	opmnctl startall
Stop all components of the Application Server, including the Management Service and WebCache	opmnctl stopall

Starting and Stopping the Management Agent

The relevant emctl commands for Linux are listed in the following table.

You must be in the AGENT_HOME/bin directory to issue the emctl commands, where AGENT_HOME is the Oracle home directory for your Management Agent. Note that this directory is different than theAS_HOME/bin directory, which is for the Oracle Application Server Control Agent.

Table 7-2 Commands to Start and Stop Management Agent

If you want to	Enter the following Command
Start the Management Agent	emctl start agent
Stop the Management Agent	emctl stop agent
Verify status of the Management Agent	emctl status agent

IMPORTANT: During a reboot of a machine, the agent startup script runs automatically to start the Management Agent. You do not have to manually start the agent in this release of Enterprise Manager.

3. EM configured to managed IAS

Application Server Control : is application used to maintain Oracle Application Server. Using Application Server Control, you can
- Start/Stop Services of Oracle Application Server (OC4J, HTTP, Web Cache, OID, SSO..)
- Configure components of OAS (Oracle Application Server)
- Manage/edit users credentials, configuration file, port number
- Monitor performance & Usages …

Start/Stop Application Server Control :
Prior to Oracle Application Server 10.1.3.X, Application Server Control used to start/stop using
emctl start¦stop iasconsole

From OAS 10.1.3.X and higher, Application Server control is controlled using opmnctl like
opmnctl startproc¦stopproc application=ascontrol 

(From 10.1.3.X and higher instead of emctl; use opmnctl to start/stop iasconsole. iasconsole will not start by default when you execute opmnctl startall)

URL to access Application Server Control
1. Prior to OAS 10.1.3.X (i.e. 9.0.2, 9.0.4, 10.1.2.X) URL to access AS Control is
http:// {hostname}.{domainname}:{em_port}/emd
Note* EM Port (usually 1156, 1810) is different from HTTP Server port)2. From 10.1.3.X URL to access  AS Control is

http:// {hostname}.{domainname}:{http_port}/em

Starting the Oracle Application Server Console

Oracle Application Server Control Console (iAS) is the Web-based management tool for Oracle Application Server and is used to monitor the Enterprise Manager targets.

After successful Enterprise Manager installation, you must manually start the iAS console before starting the Enterprise Manager console.

To start the iAS console, go to the OMS Oracle home and execute the start iasconsole command. The usage is as follows:

<OMS_Oracle_home> emctl start iasconsole

Accessing Enterprise Manager Grid Control

The Enterprise Manager Grid Control Console is the primary tool for managing your Oracle environment.

Use the following URL to log in to the Grid Control Console:

http://<oms_hostname>.<domain>:<port>/em

or

https://<oms_hostname>.<domain>:<port>/em

If you are uncertain about the port number, you can refer to one of the following files:

• ORACLE_HOME/install/setupinfo.txt as displayed by the Oracle Universal Installer at the end of the install
• ORACLE_HOME/install/portlist.ini on the Management Service machine

When the login dialog appears, enter the user name and password for the Super Administrator SYSMAN.
