Data sets used for planning, tracking, and recovery

IBM Z Workload Scheduler maintains two plans, the long-term plan and the current plan. The event-tracking functions collect status information about the work in progress, store this information in event data sets, and amend the current plan to reflect the status of operations. These planning and event data sets, as well as the data sets that are used for recovery, are described here.

When the end-to-end scheduling with fault tolerance capabilities feature is installed, IBM Z Workload Scheduler maintains the following additional data sets:

Input events data set (EQQTWSIN)
Output events data set (EQQTWSOU)
Script library (EQQSCLIB)
Current® plan backup (EQQSCPDS)
Centralized script data set (EQQTWSCS)

For details, see Tasks and data sets used for end-to-end scheduling with fault tolerance capabilities.

Every IBM Z Workload Scheduler address space that uses the Restart and Clean up feature requires the allocation of a local VSAM repository for the structured information related to each job run.
