I have a question, does CICS4.2 with MQCONN set to connect to a QSG need to have WMQ on the same LPAR?

Well, there is no MQ Client for z!
Yes, it must connect to a Qmgr on the same LPAR. |

There is client for z\OS just expensive to run. I am confused as if the CICS AOR has a connection to the QSG with the MQCONN, then how is it going to connect to the QMGR that is on the same LPAR? I might be getting senile, but I am having the hardest time wrapping my mind around this.

The CKQC CICS transaction starts the CICS-MQ adapter. CKQC panels allow you to identify the qmgr name. The adapter MQCONNects to the named qmgr. MQCONN calls in a CICS application are ignored.

A Qmgr on z/OS can allow client connections to it via the Client Attachment feature and it is now free.
No applications on z can use an MQ Client except possibly Java (but why would you?). |

Just to give you an idea of what I am trying to analyze for a possible messaging infrastructure:
In a sysplex of 4 z\OS LPARs with CICS on each LPAR with WMQ (QSG) on 2 LPARs. Can CICS communicate to the QSG from the LPARs without WMQ configured to it using the MQCONN to connect to the QSG? Or does WMQ and CICS have to be painted on the same LPAR?
Please advise,
