Updating IEASYSxx (CMAS)

In every MVS/ESA image that contains a CMAS, you need to verify that the IEASYSxx member of the SYS1.PARMLIB library that you use for MVS™ initialization includes the parameters:

MAXCAD=nnn
Set or increase the value to include the number of common MVS data spaces that are needed for each CMAS. Each CMAS needs a minimum of 6 common MVS data spaces. When setting the MAXCAD limit, allow for 6 common MVS data spaces per CMAS, in addition to any common data spaces that may be in use by other products.
NSYSLX=nnn
Set or increase the value to include the minimum number of linkage indexes (LXs) that are required by CICSPlex® SM. Because two LXs are required for the CAS and one LX is needed for the Environment Services System Services (ESSS), the minimum number of LXs required for use by CICSPlex SM is 3.
Note:
This parameter may already have been defined when you set up the CAS. (See Updating IEASYSxx (CAS).)

For additional information about these parameters, see the MVS Initialization and Tuning Reference manual.
