This section describes the compatibility issues if you have applications coded for WebSphere® Extended Deployment Version 5.1 or Version 6.0.
WebSphere Extended Deployment Version
5.1 partitioned applications are not supported on WebSphere Extended Deployment for z/OS Version 6.0.1.
If you have applications coded for WebSphere Extended Deployment Version 5.1, the alias partitioning feature can be run in WebSphere Extended Deployment Version 6.0 without affecting those applications. Applications coded for WebSphere Extended Deployment Version 6.0 with partition alias will fail in Version 5.1 with a NO_IMPLEMENT exception.
Clients can still be routed according to partition name, though. Partition alias is just another way to route, also allowing for customer grouping of partitions.
A sample WPFPartitionAliasSample.ear is provided to show how the partition alias works. Another sample, WPFMixedPartitionSample.ear, is provided to show how an application can work in partitions without an alias and partitions with aliases at the same time.
