what are the pros and cons of having MQ on the mainframe? how can one defend MQ on mainframe with respect to web services?
Thanks |

Well, for one thing, that is the only place that supports queue sharing groups. That would allow two different queue managers to actually reference that same queue. That way, if one QMGR dies, the other keeps processing the messages without waiting for an HA LPAR to take over, start up, recover and do other stuff before processing again.
There are many other reasons.

For one thing, midrange and distributed systems have yet to match the availability figures for the mainframe, at least in every shop I have seen.

IMHO the only con is if you don't have a mainframe...
otherwise, the choice is obvious for many reasons: availability, availability, availability

| And, a single mainframe can support dozens or hundreds of qmgr instances. Reduce the infrastructure. |

normally, you put WMQ on the mainframe because you have mainframe applications that want/need to use WMQ.
