DFHSIP

DFHSIP is the CICS system initialization program called by the operating system. The DFHSIP task is active during CICS/ESA initialization and termination. It has no active code while CICS/ESA is accepting logons and performing user tasks.

Hints

DFHSIP is the CICS program that appears on the Measurement Session Data report, if your installation uses the standard IBM-supplied name.

In later version of CICS, DFHSIP initializes CICS and contains code for a number of CICS domains. In CICS 4.1, code for the following domains are included in DFHSIP:

  • kernal (KE)
  • domain manager (DM)
  • dispatcher (DS)
  • dump (DU)
  • global catalog (GC)
  • local catalog (LC)
  • loader (LD)
  • lock manager (LM)
  • message (ME)
  • parameter manager (PA)
  • storage manager (SM)
  • trace (TR)

With these additional modules included in DFHSIP, the CPU time will increase considerably when upgrading to CICS 4.1.
