LABEL QUI040 NEEDS TO MAKE SURE THAT QSAPUEHB IS VALID
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: ALL IMS V12 Users of AOI exit DFSAOUE0. * **************************************************************** * PROBLEM DESCRIPTION: When running on z/OS 2.1 with the z/OS * * IGVDGNPP diagnostic tool active, IMS * * messages may not be sent to AOI exit as * * expected or abend 0C4 in DFSQUEI0. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** The AOI exit interface uses the user exit header buffer address without checking if the address is zero or not. When the address is zero and depending on what value at location 0, the next processing outcome is unpredictable. When the diagnostic tool IGVDGNPP is running, the value at location 0, that is normally zero, may be set to 55555555 or FFFFFFFF instead. In one instance, a value causes the exit to think it needs to free the user exit header block, when in fact it should not. As a result, IMS messages are not sent to the AOI exit.
Problem conclusion
GEN: KEYWORDS: ABEND0C4 S0C4 0C4 *** END IMS KEYWORDS *** DFSQUEI0 - AOI exit interface At label QUI040, validate the UEHB (user exit header buffer) address is valid to ensure it is not zero before use.
