Each module of a deployed application must be mapped to one or
more target servers. The target server can be an application server or Web server.
Before you begin
You can map modules of an application or stand-alone Web module to
one or more target servers during or after
application installation using the console. This topic
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.
About this task
During application installation, different deployment targets might
have been specified.
You use the Manage modules 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 Manage modules 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.
Attention: 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.
Procedure
- Click Applications > Enterprise Applications > application_name > Manage modules in the console
navigation tree. The Manage modules panel is
displayed.
- Examine the list of mappings. Ensure that each Module entry
is mapped to the desired target(s), identified under Server.
- Change a mapping as needed.
- Select each module that you want mapped to the same target(s).
In the list of mappings, place a check mark in the Select check
boxes beside the modules.
- From the Clusters and Servers drop-down list, select
one or more targets. Use the Ctrl key to select multiple
targets. For example, to have a Web server serve your application, use the Ctrl key
to select an application server and the Web server together in order to have the plug-in configuration
file plugin-cfg.xml for that Web server generated based on the applications
which are routed through it.
- Click Apply.
- Repeat steps 2 and 3 until each module maps to the desired target(s).
- Click OK.
Results
The application or module configurations are changed. The application
or stand-alone Web module is restarted so the changes take effect.
What to do next
Save changes to your administrative
configuration.
