Error description
You are running CICS TS 5.5 and receive the following Console error messages: DFHPI0001 An abend (code ---/AKEC) has occurred at offset X'7A76' in module DFHPISN. DFHPG0002 A severe error(code X'1920') has occurred in module DFHPGCR DFHPG0002 A severe error(code X'1920') has occurred in module DFHPGCR. DFHPI0002 A severe error(code X'0508') has occurred in module DFHPITH. In MSGUSR you may see: DFHDU0203I A transaction dump was taken for dumpcode: APIL, Dumpid: 1/0016, Tranid: tran, Tranum:nnnnn, Program: DFHPISN1. DFHPI0500 tran The CICS Pipeline Manager DFHPIPM encountered an error while trying to link to program DFHPISN1. The program abended. PIPELINE: program. DFHPI0503 tran The CICS Pipeline Manager has failed to send a response on the underlying transport. TRANSPORT: HTTP, PIPELINE: program. DFHDU0203I A transaction dump was taken for dumpcode: AXMZ, Dumpid: 1/0022, Tranid: tran, Tranum:nnnnn, Program: DFHXMAB. DFHAC2236 Transaction tran transaction number nnnnn abend AXMZ in program DFHPISN1 term ????. CICS region has a runaway time ICVR of 1 second. DFHPISN had reserved the DFHRESPONSE container and was in the process of populating the container when the ICVR timer popped and the task abended AKEC. The problem is, it never did the undo of the RESERVE_CONTAINER, which lead to the subsequent PG0002 and PI0002 errors. Additional symptoms: KIXREVDAM ABENDAKEC ABENDAPIL ABENDAXMZ
Local fix
To prevent the AKEC, increase ICVR value or specify a larger RUNAWAY value on the affected transaction definition
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Multiple errors and system dumps occur * * when a pipeline task abends during * * processing of the DFHRESPONSE * * container. * **************************************************************** If a pipeline task is abended due to the CICS runaway interval being exceeded and this takes place while the DFHRESPONSE container is being created multiple PI0002 and PG0002 errors together with system dumps occur. These occur because the reserve placed on the DFHRESPONSE container is not released in the DFHPISN recovery routine.
Problem conclusion
Code has been added to the recovery routine in DFHPISN to release the reserve.
