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:

Ingredients

  • Oracle RDBMS 10.2.0.3.0 (Enterprise Edition) and/of higher version
  • APEX 2.2.1
  • Windows 2003 / XP

Shortlist

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 (http://www.oracle.com/technology/products/database/application_express/download.html)
  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).

Step-by-step example

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).

F:\oracle\product\10.2.0\db_1\apex>sqlplus /nolog

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.

PS.

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.

Extra very useful information and examples about DBMS_EPG can be found here: http://www.oracle-base.com/articles/10g/dbms_epg_10gR2.php

  1. Sounds like or you didn’t have all the privileges granted to execute and/or select DBMS_EPQ or you didn’t install all the needed functionality in the database or you database has invalid packages.

  2. I got following thing at the end of of Oracle Apex installation.

  4. I had the same problems that many here had. Specifically, the problems with logging into to APEX using an Oracle 10.2.0.3 database with the PL/SQL gateway and subsequently NOT being able to login into the http://host:port/pls/apex/apex_admin…..

    This looks as though it applies.

    Metalink Note 422680.1
    Is it possible to have Apex 3.0 installation on 10g databases with Embeded PL/SQL Gateway?

    Short Story is that it wasn’t meant to.

    Long Story:

    Applies to:
    Oracle Application Express (formerly HTML DB) – Version: 3.0
    Information in this document applies to any platform.

    Goal
    Can we install the Apex 3.0 using the Embedded PL/SQL Gateway on 10g Databases as described on the installation guide ?

    Reference 4.2 Configuring the Embedded PL/SQL Gateway of Apex 3.0 Install Documentation.

    http://download-east.oracle.com/docs/cd/B32472_01/doc/install.300/b32468/post_inst.htm#CHDEIGGI

    Solution
    Embedded PL/SQL Gateway implementation of the Apex installation will be introduced when the 11g
    databases are rolled out for productions.
    Currently it is not possible for installation of the Embedded PL/SQL Gateway on 10g databases.

    You need to install the Apex following the 4.3 Configuring Oracle HTTP Server of the installation guide.

    http://download-east.oracle.com/docs/cd/B32472_01/doc/install.300/b32468/post_inst.htm#BHAGICFJ

    The HTTP server can be installed either from a Database companion CD or if an Application server already exists then that can be used for configuring.

    At the time of writing the Note the 11g database wasnt released for Production and also there wasnt any information on using 10g database for the same problem.

    Hi,

    I refer to my email posted on 24 May. Just to add that I tried typing in password given during APEX installation, passwords for Oracle superuser account sys and system but all failed. I also unlocked anonymous account. Can anyone tell me what else whould I try ?

    Thanks in advance for any help.

    I had the same problem, what worked for me was the unlocking of the anyonymous account (as mentioned in the article).

    My problem… access to the images that are loaded onto the XML DB. i.e. “XDB requires userid and password”.
    I have typed system/******** and remember password enough to get everything working. However, when I imported in an application… I now get “XDB requires userid and password” on all the images for the new application.
    Has anyone sucessfully setup the ACL security for the /i/ or /images/ folder on the XML DB?

    following the steps in this guide (because this solution didn’t work when I ran the 11g script.
    When I was asked for the xdb password I enter the password of an Oracle dba user, it logged on and it worked ok.
    Some times appears for the apex password and I didn’t found a solution.
    The other problem I foudn is always I went to admin logon, but logging out I found I could log in a specific workspace.
    Hope this help.

    Hello, I am getting exactly the same problem as Liam and cool_techie ie. a Windows dialog box is not letting me proceed. Has anyone got a resolution for this? Thanks, Jaideep

  17. Hi,

    I would like to know how can I implement windows authentication in APPEX (HTMLDB). I mean once the user is logged in windows and when he starts HTMLDB, he should be authenticated with the login-password used for windows.

    Thanks
    ARvind

  18. Hi cool_techie,
    I had the same issue regaring path issue. I followed the install guide for Window which asked me to run the following @apex_epg_config11 C:\TEMP , I did this but forgot to replace the path to the path were I extracted the files. I got an error, I ran again with the correct path (below)and it worked fine. Now I am having a problem logging in with the admin username and the password created during installation. Did you manage to resolve this?

    @apex_epg_config11 C:\oracle\TMP

  19. cool_techie on

    A very helpful step by step guide for installing APEX.
    I have been trying to install the same… but am stuck for last few hours. It would be great if you can help me point where I might be getting wrong:-
    1. Installed APEX.
    One error while running the apex_epg_config11: ORA-22288: file or LOB operation failed. The system cannot find the path specified.
    ORA-06512: at sys.DBMS_LOB,line 523
    ORA-06512: at sys.xmltyp,line 287

    2. After a not-so-clean install trying to open the apex_admin page, but a windows username/password dialgbox appears saying the server at XDB reuires the username and password. Am giving the username as admin and the apex password given during the installtion, but not getting thru. Am i doing the right thing.
    I seem to have been stuck (maybe stupid) and would really appreciate any help.

    Thanx.

  20. Two things come to mind, protecting the root folder.

    – One could place a index.htm(l) file which refreshes immediately to the wanted URL.via the META tag (http://www.w3.org/QA/Tips/reback). But this is more or less a workaround.
    – One could protect the folders via ACL’s. See the XMLDB Developers Guide how to implement this.
