To my knowledge, CICS connects to local MQ subsystems using an adaptor which is
essentially a program running in CICS to handle direct MQ calls from programs
in several languages. The MQ API for CICS is the same as it is for batch.
Before the implementation of TCP/IP support within MQ, the method was to go
from MQ through the CICS adaptor to CICS, then from CICS on SYSTEM-A to CICS on
SYSTEMB, then from CICS to MQ. No cross-memory services are used. AFAIK, the
methodology is very similar to the DB2 API implementation for CICS. Each CICS
region only connects to one MQ subsystem through a Resource Manager Interface,
so logistics might get more complicated with multiple CICS and MQs on the same
system.

Subject: Re: MQ/CICS and LU6.2
June,
CICS accesses MQ messages using cross-memory services. It doesn't use
LU6.2. The decision to use LU6.2 (or TCP/IP) affects how remote queue
managers and/or clients talk to each other.
The SIP override specifies the queue manager name the region connects to,
plus the initq used by CKTI on CICS.

Can someone give me the steps for the following?
On the OS/390 I want to set up an LU6.2 connection between the queue
manager and one of our CICS regions. I am reading the Intercomminication
and
System Setup Guide, but I am getting a little confused.
I am assuming that I have to define an applid for the channel initiator in
SYS1.VTAMLST in addition to a conn/sess in CICS. Is this correct?
