Weblogic Fun Times - Part 1

So part of my BAU work I dabble in the world of Oracle Weblogic Server .... like a little bit... like dip my toe in now and again...

Anyway I thought I would share some high level bite size info with you all for giggles :)

So weblogic, is the middle tier that can sit between a back-end database e.g. oracle and  services front end web applications and web services.

Here is a nice picture with stick people to show who looks after to which bit normally.

Oracle official definition: A WebLogic Server administration domain is a logically related group of WebLogic Server resources.

When you install your domain what you will have first of all is your Admin Server, this will manage your domain config.

You can administer the weblogic via its web interface known as the console. Usually a url something like http://MyDomain:7001/console/

you can also administer directly on your host server. A lot of occasions this may be a Unix/Linux platform.

You will also have an instance of the weblogic server which is your Managed Server. This is where we would deploy the applications to.

You can also utilise a weblogic cluster to provide high availability and scalability for your applications.

Weblogic also uses a utility called NodeManager that enables you to start, shut down, and restart Administration Server and Managed Server instances. As part of the start/stop process it does crash recovery checks on your Admin and managed servers to make sure we can start them backup up cleanly.

Weblogic has its own scripting tool known as WLST (WebLogic Scripting Tool) which you can script out and automate features related to the setup and configuration of your domain.

So that is our high level components in bite sized chunks.....coming up we may delve into install and high level checks.
