Types of exits

ICSF provides several types of exit points:
  • Exits that are called during initialization, stopping, and modification of ICSF itself, which are known as the mainline exits
  • Exits that are called from the services
  • An exit called when a record is read from or written to a fixed length record CKDS.
  • An exit called when you update the CKDS with a key that is entered through the key entry hardware or during conversion program processing
  • An exit called when records are retrieved from the in-storage CKDS
  • Security exits that are called during initialization and stopping of ICSF, during a call to a service, and when accessing a CKDS entry
  • An exit called at various points during KGUP processing

These topics briefly describe the different types of exits available in ICSF.

Note: Although IBM no longer supplies security exit routines, the exit points still remain.
