When used with DC/UCF, the CICS operating environment contains the components listed below and shown in the following diagram.
When CICS is used with DC/UCF, the CICS operating environment contains the following:
  • CICS application programs
  • CICS program interface module (IDMSCINT). IDMSCINT provides the necessary communication between the CICS user program and the CICS TP-monitor interface module IDMSINTC (described below).
  • CICS nucleus
  • CICS common system area (CSA). The CSA includes a common work area (CWA) that contains a fullword pointing to a table of addresses within IDMSINTC; the addresses in the table point to three entry points within IDMSINTC (described below).
  • CICS TP-monitor interface module (IDMSINTC). IDMSINTC allows CICS and DC/UCF to communicate at runtime.
  • IDMSTRUE, the task termination exit
