Configure Oracle EM dbcontrol

1 Definition

Oracle10G EM adopts the web method and is divided into two products: database control and grid control. This section describes how to create a single data dbcontrol. To install Grid control, download a separate CD.

When using DBCA to create a database, you can choose whether to enable dbcontrol. To enable dbcontrol, you need to create a sysman schema in the database to save some data of EM, this is the repository of EM ).

You can use the command line tool emca to create, modify, recreate, or delete dbcontrol configurations.

2. Syntax of Common commands

Emca-repos create creates an EM Database

Emca-repos recreate re-creates an EM Database

Emca-repos drop delete an EM Database

Emca-config dbcontrol db configure Database Control of the Database

Emca-deconfig dbcontrol db deletes the Database Control Configuration of a Database

Emca-reconfig ports reconfigure db control and agent ports

Emctl start console to start the EM console service. You need to set the ORACLE_SID environment variable before use.

Emctl stop console to stop the EM console service. You need to set the ORACLE_SID environment variable before use.

 

Note: You can check the $ ORACLE_HOME/install/portlist. ini file to find the port currently in use by dbcontrol. The default port is dbcontrol http port 1158 and agent port 3938. To reconfigure the port, run the following command:

Emca-reconfig ports-dbcontrol_http_port 1159(This command experiment failed. After running, it was still 1158. The reason is not found .)

Emca-reconfig ports-agent_port 3939
