IllegalResourceIn2PCTransactionException using JMS with ADM

SA-26053

Summary



Adaptive Decision Manager (ADM) is configured with JMS running on WebSphere. When trying to complete tasks within Pega, which involve updating a database table content, saving changes fails sporadically.

Error Messages



[Date, time, and timezone] 00000044 RegisteredRes E WTRN0062E: An illegal attempt to use multiple resources that have only one-phase
capability has occurred within a global transaction.

Steps to Reproduce



Unknown

Root Cause



A defect or configuration issue in the operating environment:
WebSphere groups Java database connectivity (JDBC) of jdbc/PegaRULES with the container-managed persistence (CMP) activity of JMS into a global transaction. With multiple resources in the same transaction, an XA driver is needed or configure ADM to use HTTP instead of JMS.

Resolution



Use an XA driver or apply HFix-28496.
