For an individual CICS region, resources are available in CSD file and during region startup they will be installed by the list mentioned in GRPLIST SIP parameter. How the same is accomplished in CICSPlex?
I heard (from a training center) that any resource definition updates/alteration in CICSPlex update only CMAS and it will be stored in the data repository and not install in the CSD of regions in CICSPlex. During region startup, how the individual regions in CICSPlex knows whether it has to install the resources from GRPLIST or CMAS?
Kindly bear me if my question or words usage is confusing. I am very new to CICS admin.
