From time to time, people on the OTN XMLDB forum, ask if it is possible to connect via the Oracle Protocol Server (aka the Oracle Listener), for instance in combination with APEX and DBMS_EPG. I am not sure if it is an already official supported environment, but the following works as demonstrated in this step-by-step manual
- Oracle RDBMS 10.2.0.3.0 (Enterprise Edition) and/of higher version
- APEX 2.2.1
- Windows 2003 / XP
The following list is the shortlist regarding installing APEX via the Oracle Protocol Server ….
1. Install the Oracle database software and apply the 10.2.0.3 patch
2. Create a database with (among others) XML DB installed
3. Download the APEX software
4. Copy the APEX directory into the %ORACLE_HOME% software path
5. Enable the HTTP (or HTTPS and/or FTP) Oracle Protocol Server (aka the Oracle Listener)
6. Install the APEX packages in the database
7. Install/enable the DBMS_EPG and DAD procedures
8. Allow anonymous access on the database HTTP port
9. Create extra shared server processes
Be-aware that if you enable access via port numbers beneath port 1024; that the user under which the process is started, needs superuser privileges. In my case the software is installed under a Oracle Windows OS user, that also has Windows local administrator privileges. If this is not the case (or you don’t want this because of security reasons) then you will have to connect on a port higher then 1024 (for instance the default 8080 HTTP XML DB port).
Create your database instance (mine has been called “LAB”) and start database and the listener service. As said, download the APEX 2.2.1 software via http://www.oracle.com/technology/products/database/application_express/download.html and unzip the file to a temporary directory. This temporary directory now holds a “core” directory which contains the APEX software.
Copy this software to the ORACLE_HOME directory (in my case %ORACLE_HOME%=F:\oracle\product\10.2.0\db_1).
Go to the created F:\oracle\product\10.2.0\db_1\core directory and set your ORACLE_HOME and ORACLE_SID (in my case this ORACLE_SID=LAB) in a command window (start=>run=>CMD)
F:\oracle\product\10.2.0\db_1>cd apex F:\oracle\product\10.2.0\db_1\apex>set ORACLE_HOME=F:\oracle\product\10.2.0\db_1 F:\oracle\product\10.2.0\db_1\apex>set ORACLE_SID=LAB
Open a SQL*Plus session and set the HTTP (and/or FTP) port you want for the APEX software (for instance default port 80 for HTTP data traffic and default port 21 for FTP data traffic).

You can check if the listener has picked up the HTTP and FTP settings by executing the following in a windows command box.

Install the APEX software by (while starting from the APEX directory) executing the following statements in SQL*Plus and executing the APEX installation script apexins.sql.
The apexins.sql has to be executed via the SYS database account and it has the following parameters:

Now login and execute the install script:

Grant anonymous access on the database / HTTP port by unlocking the anonymous account and (regarding performance reasons) increase the amount of share servers.

Now you can connect to APEX via http://yourserver:port/apex and http://yourserver:port/apex/apex_admin.
In my case this will be http://vamisnt02/apex/ and http://vamisnt02/apex/apex_admin.
Because I used “admin” as a password during the apexins.sql script you can now login into the http://vamisnt02/apex/apex_admin page with the username/password combination: admin/admin
I hope I have been of help.
Extra info on the XML DB Protocol Server can be found in the Oracle XML DB Developers Guide, among others here: http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#sthref2258
In certain cases, it may be useful to log the requests received and responses sent by a protocol server. This can be achieved by setting event number 31098 to level 2. To set this event, add the following line to your init.ora file and restart the database:
event="31098 trace name context forever, level 2"
To use HTTP(S) on the standard port, such as 80, your DBA must chown (on linux, unix) the TNS listener to setuid ROOT rather than setuid ORACLE, and configure the port number in the Oracle XML DB configuration file /xdbconfig.xml.
