BIP11g Users and Roles

Did some work on a 11g BI publisher only install recently. Opposite to OBIEE11g you can still add users directly into BIP. Be sure to give them the right roles and sync it with your weblogic security realm.

WebLogic 12c: For Admins and Java-heads, Not for Me (Yet)

Oracle lists more than 200 new features in WebLogic 12c – unfortunately, I don’t get to use them.

Installing the OSB 11.1.1.4 without using a database

It is not required to use a database when installing the OSB if you do not use the OSB Reporting or the OWSM. This is stated in the 11.1.1.3 documentation. I cannot find the same statement in the 11.1.1.4 documentation but it is still (more...)

Using encrypted credentials in WLST

Welcome to my blog. It has been underway in several years but now it is finally here :-)

Loosely typed interfaces – The Normalizer Pattern and Oracle SOA Suite

When getting two or more systems working together, the making a connection part is generally the easiest, identity propagation is a bit trickier, but many times, the syntax and semantics of one system is at odds with another one. Over the decades this has been manifest in many ways and (more...)

Set up a Weblogic Server 11g (10.3.1) JMS Store and Forward demo

Weblogic Server (supported from 9.x) contains JMS Store-and-Forward (JMS SAF) functionality.

WebLogic Server and APEX

A good friend and colleague of mine at Oracle, Mark Greynolds, shared with me his work with WebLogic and APEX and getting them to work together. I thought it was something that everyone would be interested in and asked him if he would be willing to document the steps and allow me to post them here on my blog. He was and so here it is.
