New WebLogic feature: one deployment to rule them all by Maarten Droogendijk


clip_image002 The release of WebLogic 12.2.1 has introduced some cool features. One of them: the domain partition exports. Could this feature really reduce all the deployments to just one deployment? Let’s find out!

To fully grasp the idea of just needing one deployment, we need to explain Domain Partitions first. As Oracle states: “A domain partition (partition for short) is an administrative and runtime slice of a WebLogic domain. In many ways you can think of a partition as a WebLogic micro-container.” A Domain Partition can be assigned as micro-containers called Resource Groups. Resource Groups can contain WebLogic components such as applications, libraries, JMS Servers and Data Sources.

Resource Groups and Templates

In previous WebLogic versions you would deploy WebLogic components to the whole domain (global) and have it targeted to servers or clusters. Starting from 12.2.1, you can now also deploy these WebLogic components to specific Resource Groups and Resource Groups Templates. Resource Groups can be used to group every component needed in a business flow to one container.

Using Virtual Targets, Administrators can specify on which servers or clusters the Domain Partition is available. Read the complete article here.
