CICS IA controlling region

CICS® IA stores all the information about which collections and what data you want to collect, and so on, in a VSAM file. This file is known as the CONTROL file.

The IA Dependency and Affinity Collectors save the data collected into VSAM files. These files are called COLLECTOR files. The command flow collector saves the data into CICS User journals, (logstreams).

CICS IA is designed to share these VSAM files and logstreams across CICS regions, so you can administer and operate CICS IA from one region. This region is called the CICS IA controlling region. From this controlling region you can administer the CICS IA options and operate, start and stop, the CICS IA collectors.To operate the CICS IA collector the controlling region needs a connection to the regions that you want it to start or stop.
