Setting up a CICS managed application system (MAS)
There are a number of steps you must perform so that a CICS® system can be known as a managed application system (MAS) to CICSPlex® SM.
Note: If a MAS specifies a CMASSYSID and the CMAS is active
but does not manage the CICSplex, the MAS waits until the specified
CMAS is managing the CICSplex before it joins the CICSplex. This behavior
is the same as when CMASSYSID is not specified.
