In earlier blog entries I informed you that WebSphere MQ for z/VSE was withdrawn from service September 30, 2015. Service extensions are possible. As an alternative you may use the WebSphere MQ Client for VSE . The most important function, that is required for the client - the MQ Trigger Monitor , is available for z/VSE 5.1, 5.2 and 6.1 since last year. See my related blog entry . The WebSphere MQ Client for VSE web page was just updated, see here .
