The Cross-Platform Scheduling Checkpoint data set contains checkpoint information that the Cross-Platform Tracking System (XTRK) uses to coordinate tracking functions with non-MVS platforms. For the sample JCL to allocate this file, see member AL2XPSCK in the JCL library (CAL2JCL).
Note: Each copy of XTRK requires its own checkpoint file.
