Approximately 30 minutes
Oracle Enterprise Manager Express enables you to perform administrative tasks such as managing user security and managing database memory and storage. You can also view performance and status information about your database. In this tutorial you will perform configuration steps to enable you to access Enterprise Manager Express and view the Database Home page.
The following is a list of software requirements:
- Oracle Database 12c
Before starting this tutorial, you should:
- Have installed Oracle Database 12c.
Configuring the HTTP Port
You can access Enterprise Manager Database Express using the URL that was displayed during installation. The default port used is 5011. In case you want to use a different port, you need to configure the port using the dynamic protocol registration method. After the HTTP port is configured, you use it to access Enterprise Manager Express. In this tutorial, you will configure Enterprise Manager Database Express to run on port 8080.
Open a terminal window and execute the oraenv command to set the environment variables.
Verify that the listener is started by executing the lsnrctl
Log in to SQL*Plus as the SYSDBA user and verify that the DISPATCHERS parameter in the initialization parameter file includes the PROTOCOL=TCP attribute.
Execute the DBMS_XDB.setHTTPPort procedure to set the HTTP port for Enterprise Manager Express.
Accessing the Database Home Page
The Database Home page is the main database management page in Enterprise Manager Database Express. To access the Database Home page, perform the following steps:
In your Web browser enter the URL to access Enterprise Manager: http://database-hostname:portnumber/em. In this case, since the database is installed in the local machine, localhost is used for database-hostname.
Log in to Enterprise Manager Database Express with an authorized user account such as SYSTEM. Enter the username and password in the appropriate fields. Click Login.
The Database Home page is displayed. Continue with other tutorials in the series or log out of Enterprise Manager Database Express.
