Error description
After an webservices task suffered an abend (in this case an abendAUEP, and U4087 accompanied with message DFHPI0500), the associated Pipeline resource (EXPIPE01) get stuck with 'being disable' after a subsequent SET Disable cmd. The problem is exposed by an abend within a pipeline message handler. This causes the PIPM START_PIPELINE to complete with EXCEPTION REASON(UNHANDLED_ERROR) and this means that we fail to issue a RELINQUISH_PIPELINE call which would drop the usecount of the pipeline to 0. The non-zero usecount stops the pipeline from being disabled or re-installed.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: A PIPELINE resource cannot be disabled * * even if it is not currently in use. * **************************************************************** * RECOMMENDATION: * **************************************************************** A PIPELINE resource cannot be disabled whilst it is in use. DFHPIPM calls ESTABLISH_PIPELINE to indicate that the pipeline is currently being used for a given task. It should always call RELINQUISH_PIPELINE when the pipeline is finished with, but there are some error scenarios where the pipeline resource is not relinquished. This blocks the resource from being disabled as CICS incorrectly thinks that it is still in use.
Problem conclusion
Temporary fix
FIX AVAILABLE BY PTF ONLY
Comments
DFHPIPM has been changed to relinquish the pipeline in all scenarios where it has been previously established.
