Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Various restart and recovery problems * * when using WS-AT. * **************************************************************** * RECOMMENDATION: * **************************************************************** This APAR addresses a number of issues relating to Web Services Atomic Transactions (WS-AT) resync work within CICS TS 3.1. It also addresses some further problems when interoperating with WebSphere Application Server. These problems include: - The <wsa:ReferenceProperties> element sent out by CICS contains a token to enable the correct task to be identified when future WS-AT messages are received. CICS is unable to distinguish between tokens issued for this run of CICS and tokens relating to tasks from previous runs of CICS which have been restored from the log and are undergoing resync processing. - The pipeline resync task (CPIS) was being attached at startup once for every task recovered from the log that had PIRS links. However the first CPIS task processed all PIRS links in the system making the other tasks redundant. - CICS was not sending <wsa:Replay> messages to the correct endpoint in this customer's case. This was because CICS was using the endpoint from the original Web service request which is for the registration service instead of using the endpoint from the RegisterResponse message which is for the coordination service. - WebSphere Application Server 6.0.2.15 onwards supplies both <wsa:ReferenceProperties> and <wsa:ReferenceParameters> elements. CICS was not able to return these correctly when both were in the same message leading to XML parsing errors in WebSphere. - CICS as a WS-AT participant did not handle WS-AT transaction timeout correctly when waiting for the next protocol message. - CICS did not issue any informational messages when backing out the unit of work as a WS-AT participant. The unit of work was still backed out correctly though. - If a <wsa:Replay> message was received by CICS it sent the required reply to the specified endpoint address and then returned an HTTP 200 OK response to the original message. This ordering caused locking problems in WebSphere and the first message, which the transaction in WebSphere needs to continue processing, gets discarded. Additional Keywords: ReferenceProperties ReferenceParameters Replay
Problem conclusion
The CICS WS-AT support has been enhanced to correct these issues. The CICS Transaction Server for z/OS Version 3 Release 1 CICS Trace Entries manual (SC34-6443-03) will be updated as follows: Add the following new trace entries to the end of Chapter 28 'Pipeline manager domain trace points' Point ID Module Lvl Type Data PI 1804 DFHPIIM PI 2 Recreate token 1 - Token 2 - Object Address PI 1805 DFHPIIM PI 2 Create CTX token 1 - Token 2 - Object Address PI 1806 DFHPIIM PI 2 Lookup CTX token 1 - Token 2 - Object Address PI 1807 DFHPIIM PI 2 Update CTX token 1 - Token 2 - Object Address PI 1808 DFHPIIM PI Exc CTX Function Fail 1 - Function Name 2 - Token PI 1809 DFHPIIM PI 2 Destroy CTX token 1 - Token PI 1810 DFHPIIM PI 2 Recreate CTX token 1 - Token 2 - Object Address The CICS Transaction Server for z/OS Version 3 release 1 CICS Messages and Codes manual (GC34-6442-03) will be updated as follows: Add the following two new messages at the appropriate place in chapter 1 'DFH messages', section 'DFHPIxxxx messages'. DFHPI0732 DATE TIME APPLID A REQUEST TO ROLLBACK UNIT OF WORK - X'UOWID' HAS BEEN RECEIVED FROM A REMOTE WS-AT COORDINATING TRANSACTION.
