Error description
After RRS failure, application thread (WMB in this case) didn't become INDOUBT even though it terminated at between commit ph1 and ph2 (the thread completed ph1 prepare process and don't start ph2 commit process yet). Next, RRS restarted but resync process didn't take place. After that, we restarted QMGR, then the thread was detected as INDOUBT. This caused the thread remains as INDOUBT unless RRS is recycled again.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1 and Release 1 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Indoubt tasks remain indoubt following * * RRS failure, and require the queue * * manager to be restarted to resolve. * **************************************************************** * RECOMMENDATION: * **************************************************************** While an RRSBATCH application is performing Phase 1 Commit, an RRS failure occurs. The UR being committed is logged as indoubt by MQ, however the RRS failure prevents the UR being recorded as indoubt in RRS. When RRS restarts CSQ3RRSR is called to resync with RRS, however as RRS has no knowledge of the indoubt UR, MQ does not process it. The UR remains indoubt until the queue manager is restarted, at which point it is backed out.
Problem conclusion
CSQ3RRSR is changed to backout any indoubt RRS UR's which are not known about by RRS. 010Y 100Y CSQARIB CSQ3RRSR CSQ3RRSX
