Configure enterprise application files

We can change the configuration of a Java EE application or module deployed on a server.

We can change the contents and deployment descriptors of an application or module before deployment, such as in an assembly tool. However, it is assumed that the module is already deployed on a server.

Change an application or module configuration consists of one or more of the following:

If an application is running, changing an application setting causes the application to restart. On stand-alone servers, the application restarts after you save the change. On multiple-server products, the application restarts after you save the change and files synchronize on the node where the application is installed.

To control when synchronization occurs on multiple-server products, On the Console preferences page, deselect...

Complete the following procedure to change the settings of an application or module using the admin console.


Procedure


Results

The application or module configuration is changed. The application or standalone web module is restarted so the changes take effect.

New feature: If you updated module metadata while the application was running, restarting the application might not be sufficient for the changes to take effect. For example, if you changed descriptors in running Java EE 6 applications that use annotations, reinstall the application. If you changed classes that introduce, remove, or alter class hierarchies within an application, and those changes impact annotated classes, you also must reinstall the application.


What to do next

If the application or module is deployed on a cluster and we have no more configuration changes to make, click Rollout Update on the Enterprise applications page to propagate the changed configuration on all cluster members of the cluster on which the application or module is deployed. Rollout Update sequentially updates the configuration on the nodes that contain cluster members.

Save changes to your administrative configuration.

On multiple-server products, the application binaries are transferred to nodes when the configuration changes on the dmgr synchronize with configurations for individual nodes on which the application will run.
