Abstract:  Enable use of 1PC Resource with 2PC Resources if 2PC are read only

Description/symptom of problem:  

It is valid to enlist a 1 Phase Commit resource into a global
transaction with other 2 Phase Commit (XA) resources and to have the
1PC resource successfully commit as long as all of the 2PC resources
are used as read only resources.

This Interim Fix corrects the situation where the enlistment of the
1PC resource is rejected if 2PC resources are already in the transaction.

A 1PC resource can now be enlisted with 2PC resources, if however any
2PC resource is not used for read only the WTRN0063 message is given at
transaction prepare time and the transaction rolled back.

If update capability is required to both the 1PC and 2PC resources
then Last Participant Support of the WebSphere Enterprise product
should be used.
