Problem summary
**************************************************************** * USERS AFFECTED: * * All users of IBM MQ for z/OS Version 9 Release 0 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: * * Incorrect configuration event messages are written, and/or * * abend 0C4 occurs when issuing SET CHLAUTH(x) TYPE(BLOCKUSER) * * to create or delete chlauth rules when the USERLIST * * parameter contains multiple userids. * **************************************************************** * RECOMMENDATION: * * None * **************************************************************** When issuing the SET CHLAUTH(x) TYPE(BLOCKUSER) command, rsiAddUserBlockList and rsiRemoveUserBlockList are called to add/remove control blocks for each specified userid. If configuration events are enabled, the code responsible for generating event messages recording the commands does not correctly account for multiple users being specified. In the case of rsiAddUserBlockList this results in configuration event messages with Reason=MQRC_CONFIG_CHANGE_OBJECT with incorrect values in the MQCACH_MCA_USER_ID_LIST parameter being written when a new rule is created, instead of a message with Reason=MQRC_CONFIG_CREATE_OBJECT. In the case of rsiRemoveUserBlockList, an attempt is made to write event messages with Reason=MQRC_CONFIG_CHANGE_OBJECT instead of the expected event message with Reason=MQRC_CONFIG_DELETE_OBJECT, however an invalid memory reference results in the command abending S0C4.
Problem conclusion
rsiAddUserBlockList and rsiRemoveUserBLockList are changed to correctly generate event messages whene creating/deleting rules with multiple users specified in the USERLIST paramater.
