Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: When performing XA work over an IPIC * * connection an attempt to complete a * * unit of work that didn't exist was * * made. All subsequent calls to * * transaction CISX terminated with an * * abendAIPJ. * **************************************************************** * RECOMMENDATION: * **************************************************************** A CICS Transaction Gateway (CTG) XA client requests completion of a non-existent unit of work. The CICS 'Resync Recovery' transaction CISX returns an IS7 flow to inform the client of the error. The CTG client subsequently attempts to recover all the in-doubt XA transactions by sending an HTTP POST request with a CONTENT-LENGTH of 0. The request is handled on the server by the CISR transaction which in turn invokes DFHISZA receive processing. DFHISZA calls DFHISSR to receive the data, as part of this processing issb_data_length is updated to 0. DFHISZA then attempts to check the received data for an IS type 7 field, even though no data was received. The check_for_is7 procedure references issb_buffer which has not been updated and contains residual data. Invalid processing of this residual data causes the reported messages DFHIS4000 and DFHIS0002. The server transaction CISX ABENDs AIPJ. The symptoms of the problem may vary dependent on the residual data in issb_buffer. Additional keywords: MSGDFHIS4000 MSGDFHIS0002 ABENDAIPJ
Problem conclusion
DFHISZA receive processing has been changed to check if any data was received before driving the check for the IS7 header.
