In the context of IMS log records and system monitoring, this code is a hexadecimal representation used by mainframe performance management tools to identify a particular type of system checkpoint. Technical Definition

: In the event of a system failure, these log records provide the "snapshot" necessary for the system to restart and restore data integrity.

Specifically, is the identifier for a Checkpoint ADSC (Active Dataset Control) record. This record is part of the system's logging mechanism that tracks the state of active datasets during a checkpoint process. Functional Role in Mainframe Systems
