Redeploying Applications in a Production Environment 8-17
The Administration Console enables you to interactively modify individual deployment configuration properties, while weblogic.Deployer only allows you to
specify an updated deployment plan file to use for reconfiguring the application.
8.8.1 Modifying a Configuration Using the Administration Console
The Administration Console enables you to reconfigure all deployment configuration properties for an application, including properties that were not included in the
applications deployment plan. If an application was deployed with a deployment plan, the Console displays any deployment plan configuration properties in the plan
in the Deployment Plan tab for the application.
The remaining configuration tabs for an application enable you to change other WebLogic Server configuration properties. The exact properties that are available for
configuration depend on the type of application or J2EE module that is deployed. These tabs are available regardless of whether or not the application was deployed
with an deployment plan.
Note that certain configuration changes are safe to apply to running production applications, while other changes require you to shut down and restart the application.
See Section 8.8.4, Understanding Redeployment Behavior for Deployment
Configuration Changes .
8.8.2 How Configuration Changes Are Stored
When you use the Administration Console to make changes to properties that were defined in a deployment plan, the Console generates a new deployment plan that
containing variable definitions for the new properties you modified, as well as any existing variables defined in the plan. You can select where to save the new
deployment plan.
8.8.3 Updating an Application to Use a Different Deployment Plan
The weblogic.Deployer utility enables you to update an applications deployment configuration by providing a new deployment plan to use with the application.
To reconfigure an application with a different and valid deployment plan, use the -update
command and specify the new deployment plan file, as in: java weblogic.Deployer -adminurl http:localhost:7001 -user weblogic
-password weblogic -update -name myTestDeployment -plan myDeploymentsmyNewPlan.xml
Note: The updated deployment plan must be valid for the applications
current target servers, or the configuration update will fail.
Note:
Certain configuration changes are safe to apply to running production applications, while other changes require you to shut down and restart the
application. See Section 8.8.4, Understanding Redeployment Behavior for
Deployment Configuration Changes .
