Error description
Customer use the TLIM= parm to control the number of application program abends. But the dependent region terminated as result of some abend u0243. Problem is the TLIM counter (RCTCTR) increments incorrectly by the pseudo-abend U0243 in DFSPCC20.

Problem summary
**************************************************************** * USERS AFFECTED: All IMS V11 MPP and/or JMP region users that * * specify a Termination Limit count * * (parameter TLIM= ) on their DFSMPR and/or * * DFSJMP procedures. * **************************************************************** * PROBLEM DESCRIPTION: The Termination Limit count (TLIM) * * value for an MPP or JMP region is * * incorrectly incremented after an * * ABENDU0243 condition. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** If an OTMA or APPC message expires after it is enqueued but before the application message GU to the IOPCB has completed, an ABENDU0243 is produced. As this U243 abend is a pseudo-abend, it should not affect the termination limit option value (TLIM=) specified on the IMS MPR or JPM procedure. However, this is not the case if the GU to the IOPCB is the "Prime GU" which is issued by IMS prior to the scheduling of the application program. The reason this occurs is because module DFSPCC20, when issuing the abend in this instance, is updating a different PARMBLK field from which module DFSRRC10 is checking when determining if TLIM incrementation should be bypassed. Hence, the termination limit counter becomes incorrectly incremented. This action could result in the MPP and/or JMP region being terminated inappropriately due to its specified TLIM value having been reached. When the U0243 abend is issued from DFSPCC20, the PARMBLK field that DFSRRC10 should be checking is PCECB.
Problem conclusion
GEN: KEYWORDS: *** END IMS KEYWORDS *** Code in modules DFSRCJM0 and DFSRRC10 has been added to also interrogate the contents of PARMBLK field PCECB when determining whether or not the TLIM count for an MPR and/or JMP region should be incremented.
