Redeployment of a connector module maintains all connector connection pools, connector resources, and administered objects defined for the previously deployed connector module. You need not reconfigure any of these resources.
However, you should redeploy any dependent modules. A dependent module uses or refers to a connector resource of the redeployed connector module. Redeployment of a connector module results in the shared class loader reloading the new classes. Other modules that refer to the old resource adapter classes must be redeployed to gain access to the new classes. For more information about classloaders, see Classloaders.
During connector module redeployment, the server log provides a warning indicating that all dependent applications should be redeployed. Client applications or application components using the connector module’s resources may throw class cast exceptions if dependent applications are not redeployed after connector module redeployment.
To disable automatic redeployment, set the --force option to false. In this case, if the connector module has already been deployed, the Application Server provides an error message.
