Any application server need to provide a requirement to isolate the projects, contents, resources among the development teams in the dev-phase and for managability while in production stage.

Oracle iAS / OC4J allows the user to create a new instance of container and running them parallely (this can be done using command line as well from the Enterprise manager - will create a entry for this soon).

Similarly, BEA Weblogic (Oracle Weblogic I mean :) ) also provides us with a way of creating a new instance of container for managability of the code/projects/content/resources. The concept is same but the terminology is different. Weblogic calls it as domain.

Creating a new domain helps to isolate all the resources allocated to that new domain which also includes development environment (Weblogic calls it as Weblogic Workshop), JVM settings, physical directories, ports, projects and what not. One domain doesnt interfere with another and can parallely. Users have a choice of deploying their projects to one of the domains, except that they need to configure the settings accordingly.

I have an application to test on Weblogic and I have created 8 domains, and was testing my project in each of the domain with different settings. Ofcourse, my RAM is small, so I need to switch on and off the domains accordingly and at a time, 3 of them were running parallely. It really helped me to test my application in a better and faster way.

For the beginners or for those who are new to Weblogic, I guess this writing would help in creating a Weblogic domain as a quick reference. Also, included few issues which I encountered while running my application.
