Configure Oracle Application Express (APEX) in Oracle 11gR2

In order to access the APEX application, either the embedded PL/SQL gateway or Oracle HTTP server with mod_plsql is needed. For simplicity, I’ve decided to go with the former. By using the embedded PL/SQL gateway, it will run using the Oracle XML DB HTTP server which is already in Oracle database, so there is no need to install a separate HTTP server. The Oracle’s document here explains about this as well as provides the detailed information on the post-installation.

1. To configure the embedded PL/SQL gateway:

Go to the $ORACLE_HOME/apex directory.

2. Use SQL/Plus to connect as SYS to 11g database where APEX is installed.

SYS AS SYSDBA@DB11G> @apxconf

PORT———-8080

Enter values below for the XDB HTTP listener port and the password for the Application Express ADMIN user.

Default values are in brackets [ ].

Press Enter to accept the default value

Enter a password for the ADMIN user [] admin_password

Enter a port for the XDB HTTP listener [ 8080]

…changing HTTP Port

PL/SQL procedure successfully completed.

PL/SQL procedure successfully completed.

Session altered.

…changing password for ADMIN

PL/SQL procedure successfully completed.

Commit complete.

3. Unlock the ANONYMOUS account.

SYS AS SYSDBA@ DB11G > ALTER USER ANONYMOUS ACCOUNT UNLOCK;

User altered.

4. Enable Oracle XML DB HTTP server

SYS AS SYSDBA@ DB11G > EXEC DBMS_XDB.SETHTTPPORT(8080);

PL/SQL procedure successfully completed.

SYS AS SYSDBA@ DB11G > COMMIT;

Commit complete.

5. We’re now ready to access APEX.

http://host:port/apex

http://host:port/apex/apex_admin — for admin page

Port in this case is 8080 which is the default.
