Each module of a deployed application must be mapped to one or more target servers. The target server can be an application server, cluster of application servers or Web server.
Before you begin
You can map modules of an application or standalone Web module to one or more target servers during or after application installation using the console. This article assumes that the module is already installed on a server and that you want to change the mappings.Before you change a mapping, check the deployment targets. You must specify an appropriate deployment target for a module. Modules that use Version 6.x features cannot be installed onto a Version 5.x target server.
Why and when to perform this task
During application installation, different deployment targets might have been specified.You use the Map modules to servers panel of the administrative console to view and change mappings. This panel is displayed during application installation using the console and, after the application is installed, can be accessed from the settings page for an enterprise application.
On the Map modules to servers panel, specify target servers where you want to install the modules contained in your application. Modules can be installed on the same application server or dispersed among several application servers. Also, specify the Web servers as targets that will serve as routers for requests to your application. The plug-in configuration file plugin-cfg.xml for each Web server is generated based on the applications which are routed through it.
Steps for this task
Result
The application or module configurations are changed. The application or standalone Web module is restarted so the changes take effect.What to do next
If the application or module is deployed on a cluster and you 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.
In the Network Deployment product, the application binaries are transferred to nodes when the configuration changes on the deployment manager synchronize with configurations for individual nodes on which the application will run.
