DBMS_EPG – The Embedded PL/SQL Gateway in Oracle 10g Database R2

 

I’ve been playing around with the DBMS_EPG package in Oracle 10g Database Release 2. This allows you to configure Database Access Descriptors (DADs) to run mod_plsql applications directly from the database without using an application server or the HTTP server from the companion CD. Instead it uses the XML DB HTTP server. I’ve written an article on it on my website:

DBMS_EPG – The Embedded PL/SQL Gateway in Oracle 10g Database R2

It definitely works, but I’ve tried it on both RHEL4 and Windows and it feels a little dodgy. I think I’ve already found one bug, mentioned in the article, but it might just be me doing something wrong. I’m not sure if it’s ready for a production application, but it’s certainly a nice idea.

  2. Jeff: Haven’t you done any PL/SQL web applications?

    I often write internal utility/support websites using mod_plsql because it’s so simple. I guess I should start messing with HTML DB 🙂

  4. Hello, is there a way to prevent the EPG HTTP server to ask database username and password at the first connect with the browser?

    With mod_plsql we could store database credential in the DAD but with EPG this doesn’t seem to be possible.

    Thank you. Kind regards, cris119@operamail.com

  6. Hi all!

    Yes, you can orevent the EPG HTTP server to ask the username and password. For it,you need
    to do this steps:

    1. Create dad with dbms_epg.create_dad
    2. Authorize user to created dad with dbms_epg.authorize_dad
    3. Set database username to created dad with dbms_epg.set_dad_attribute

    For steps 2 and 3, use the same user.

    Regards,
