Application Express comes packaged with the OracleXE and Oracle11g database versions. In XE you can get started with APEX right away. In 11g the embedded PL/SQL gateway has to be configured first. These steps take you through the process of running the configuration script apxconf.sql.
Running this script enables you to configure the port for the Oracle XML DB HTTP server and to specify a password for the Oracle Application Express ADMIN account. Then you unlock the ANONYMOUS account.
Perform the following steps:
1. Open a terminal window and enter the following commands:
2. Enter an administrator password for the Application Express Administrator account and press Enter.
3. Enter 8080 for the port for the XDB HTTP server and press Enter. This is also the default port. Change this number when another application (eg. Tomcat) is running on the same port. Keep in mind that ports below 1024 are not advisable when running Linux/Unix.
(The embedded PL/SQL gateway has now been configured.)
4. Unlock the anonymous user. From your terminal window, enter the following command:
ALTER USER ANONYMOUS ACCOUNT UNLOCK;
And now you’re all set to start developing APEX applications in 11g.
When you later want to change the port on which APEX is configured, you can run the following command:
If you want to check what the current port is, use the following query:
select dbms_xdb.gethttpport from dual;
