WebSphere MQ is also a (most excellent) Java Message Service provider for z/OS, which is probably why the vendor recommended it. WebSphere Application Server for z/OS also provides JMS support, but then you'd have to figure out how to interface WAS to whatever else you want (i.e. your mainframe applications). One popular way would be via.... WebSphere MQ. :-)
Conceivably you could cobble something JMS together and run it on Java on z/OS, but then you'd be responsible for the stream of costs associated with creating, maintaining, and managing it, plus you'd have to figure out how to connect it. (You could write your own operating system, too, if you really want.) Considering that you're asking about a vendor application that you're buying instead of building, you've probably already ruled out building. Microsoft Message Queuing runs only on Windows (last I checked), so if you want to connect Windows systems to this vendor application, that's an option. You can't run it on z/OS (or on several other operating systems), so you'd need something else to bridge between Microsoft and any other platform (including z/OS), and that bridge would have to be a Windows system. And then you'd need to buy, maintain, and manage that, plus figure out how to connect it. Other bridge approaches are possible, with the same issue. Note that WebSphere MQ for z/OS is sub-capacity licensed. Maybe the vendor is correct. -------------------------------------------------------------------------------------------------------- Timothy Sipples Resident Enterprise Architect (Based in Singapore) E-Mail: timothy.sipp...@us.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
