Programming model extension migration

 

WAS edition contains several programming model extensions (PMEs) that previously were available only by obtaining a different product edition. This article describes the movement of a subset of PMEs to WebSphere Application Server V6.1 from the following products:

 

Overview of PME migration

The migration of PME services to WAS V6.1 is handled on an individual basis. For PME services that are not supported in WAS Version 6.1, all configuration information is removed. For PME services that are supported in WAS V6.1, the configuration from the previous release environment overwrites the values in the new release.

 

Validating PMEs

As part of application installation, both during migration and outside of migration, applications are validated to ensure that they only use resources for services that are supported by WAS V6.1. Any application that uses a resource for a service that is not supported by WAS Version 6.1 will not work correctly, and an error will be issued indicating that the application cannot be installed.

 

Running a mixed-node environment

When running in a mixed-node environment such as a WAS V6.1 deployment manager managing WebSphere Business Integration Server Foundation V5.1.x nodes, the first syncNode performed by the system downloads a configuration from the WAS V6.1 deployment manager to the WebSphere Business Integration Server Foundation V5.1.x nodes. Therefore, any PME service that is not supported by WebSphere Application Server V6.1 will be rendered inoperable on the WebSphere Business Integration Server Foundation V5.1.x node.
