Single-record, Read-write installation exit

ICSF provides an exit that is called when a record is read from or written to a CKDS. ICSF calls the single-record, read-write (CSFSRRW) exit under these conditions:
  • The PCF conversion program converts a record into ICSF CKDS format. The conversion program calls the exit before it writes a converted record to the ICSF CKDS.
  • ICSF reenciphers a disk copy of a CKDS under a new master key. ICSF calls the exit two times during this processing; after ICSF reads a record to reencipher it and before ICSF writes the reenciphered record.
  • ICSF refreshes the in-storage copy of a CKDS. ICSF calls this exit after reading a record from the disk copy to place into storage.

Using the exit, you can do such things as prevent the record from being processed, or add user information to the record.

Note: This exit is given control only for a fixed-length record CKDS. The exit does not work with the variable-length record format of the CKDS.
