Error description
Transaction routing from non CICS/TS to CICS/TS, flow a capability exchange which specifies ISCE_PREFERRED_RECOVERY of ISCE_RECOV_XA. Then a transaction routing from non CICS/TS to CICS/TS over IPIC always fails because non CICS/TS gets an IS07 from CICS/TS with a Sense code (X'08640001'). The problem appears to be with the way CICS handles XA sync-points with IPIC. APAR PM87755 raised to route RET APAR PM27349 fix from CICS/TS 4.1 to CICS/TS 4.2.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Transaction Routing from a non-CICS/TS * * partner to CICS/TS over an IPIC * * connection fails when the partner * * receives an IS7 error flow at * * end-of-task. * **************************************************************** * RECOMMENDATION: * **************************************************************** A non-CICS/TS partner has an IPIC connection to CICS/TS 4.2. The capability exchange between the two partners specifies isce_recov_xa for the XA recovery manager, rather than isce_recov_cics for the CICS recovery manager as would be the case when both partners were CICS/TS. A transaction is routed from the non-CICS/TS partner to CICS/TS where it runs as expected. However a failure occurs during end-of-task syncpoint processing when CICS/TS attempts to free the IPIC session which is still in send state and in-use. CICS/TS sends an IS7 error flow to the TOR carrying SENSE(08640001) to inform it of the error. The error occurs because CICS/TS does not release the surrogate terminal on the AOR during end-of-task processing. Additional keywords: PM27349
Problem conclusion
CICS Transaction Routing over IPIC support has been changed for the reported problem with a non-CICS/TS TOR. During end-of-task syncpoint processing CICS will now attempt to free the surrogate terminal on the AOR before attempting to free the IPIC session to the TOR. If the attempt to free the surrogate terminal fails a new exception trace point, tid_isju_tfrf_failed, will be issued. The CICS Transaction Server for z/OS V4.2 Trace Entries manual, SC34-7187-01, will be changed to add a new 'IS 130B' exception trace point after the existing 'IS 1302' entry. The new trace point has the following characteristics: Point ID ....... IS 130B Module ......... DFHISJU Level .......... EXC Type ........... RELEASE_FACILITY_FAILED Data ........... 1 DFHRMLKM parameter list 2 DFHTFRF parameter list
