Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4 occurs in CSQMDCKW when * * processing a PTF command containing * * parameters represented internally by an * * mqcharv structure (for example * * MQCA_TOPIC_STRING), or containing a * * filter on such parameters. * **************************************************************** * RECOMMENDATION: * **************************************************************** While parsing affected PCF commands, CSQ9SCN3 detects parameters that need an mqcharv structure to be built, and adds this to the TCS. This mqcharv contains a pointer to the string token that was parsed from the input PCF message. However, the storage containing the token is freed before the TCS is passed to the appropriate command processor routine, leading to the reported abend 0C4 when the value is referenced.
Problem conclusion
CSQ9SCN3 is changed to allocate a new area of storage that will not be freed until the command completes, and to reference this in the mqcharv structures used internally. 000Y CSQ9SCN3
