Although I am busy moving to Oracle VM I needed to access one of my systems on VMWare on my laptop which I had not used for a while.
The console of VMWare did not load. Ok - I though his might be due to some networks which I had disabled on Windows. Enabled them - no result. Checking the VMWare services I found out that the VMWare Host Agent was not running. So I restarted it. Crashed again.
Obviously the next step is to check the Windows event viewer. To my surprise the System Log could not be displayed.
It’s coming on 4 years now that I’ve been running NServiceBus. How the time flies. As it has worked its way into the critical infrastructure of many organizations, more and more managers have been asking me questions about how this .NET OSS thing works.

I was worried as I ran into a problem with the Database Vault security. I configured a new realm in a database where the Oracle E-Business Suite is running. The main idea was to have a user for the OBIEE that should have only limited access.
Yesterday I attended a Lessons Learned session for a Software Development project where I’ll be involved in the upcoming phase. All participants shared their opinion on the negative and positive experiences. What went well and what needed improvement.

When you are working with Weblogic JDBC Datasources for example in a Web Application, EJB or in an AQ or Database resource adapter then there is a possibility that the database sessions are in an invalid state when you change something like a package or object type in the database. This can be solved by restarting all the managed servers, reset all the Datasources in the Weblogic console or use this ANT or WLST script. This script is an ANT file where I use the WLST ANT task to fire some wlst and phyton commandos.
Almost at every conference, event, training, or consulting engagement someone asks for my opinion on the whole design for testability thing. I’m not quite sure why I haven’t blogged on this topic, especially at the time that a lot of the other bloggers were weighing in, but better late than never.
Before getting into that, I [...]
Oracle Weblogic Application Server has a lot of features to make your Web Applications or Web Services Scalable and High Available. To achieve Scalability you can add managed servers to a WLS cluster and High Availability can be achieved by Server and Service migration. The only thing Weblogic does not provide for you is a one shared IP address for the outside HTTP world. You don't want the user or application connect to one specific managed server of the cluster.
