Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 0 Modification 0 and Release 1 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: System topics are defined with an * * incorrect topic string ' ' when using * * commands generated by the MAKEDEF * * option of CSQUTIL. * * This can lead to topic strings * * generated based on these objects being * * unexpectedly prefixed with '/'. * **************************************************************** When CSQUTIL is used with the MAKEDEF option, the utility creates the DEFINE TOPIC command assuming a minimum length of 1 for the topic string attribute, resulting in topics with the null topic string '' replaced with a blank topic string ' '. However there are system topics (SYSTEM.BASE.TOPIC, SYSTEM.BROKER.DEFAULT.STREAM and SYSTEM.BROKER.DEFAULT.STREAM) which can validly contain a null topicstr. If this output is subsequently used to redefine the topics, this results in these system topics being defined with the wrong topic string.
Problem conclusion
CSQUCMDS is changed to correctly handle topics with a null topic string.
