The CICS® IA control file is a recoverable VSAM KSDS file that holds a single header record that holds global options that apply to all the CICS regions, a single DEFAULT control record that contains the default values for all regions and one control record for each CICS region being monitored that contains options that overrides the default record.
The record is updated whenever any of the above information changes, when the Collector options or statistics for this region change, or, the Collector state changes to STOPPED on this region.
The CICS IA control file also holds a USER control record that is used by the CINC transaction and contains individual user's Command Flow options and regions configurations.
The CICS IA
User Command Flow Utility uses the control file for regions configuration
data, global options and user's control data. The administration
functions for these types of information are supported by the CINT
transaction, which supplies options to add, copy, delete
and detail user's control data
. The initial values of user's
control data are default values.
To control the operation of multiple instances of the Command Flow Utility, running on different CICS regions, from a single CICS terminal, it shares the Control record file across all the regions being monitored. To do so, you can use either a VSAM record-level sharing (RLS) or a function shipping to a file-owning region.
