History Jobs File

During New Day processing, jobs that have ended OK or whose retention period has expired according to job scheduling definition parameters are deleted from the Active Jobs file.

These jobs can be placed in the History Jobs file during New Day processing. This is an optional feature that can be activated by the INCONTROL administrator. Activation of this feature is described under the HIST parameter in the INCONTROL for z/OS Administrator Guide.

Jobs in the History Jobs file can, by request, be restored to the Active Jobs file, for subsequent restart.

Jobs remain in the History Jobs file until they are deleted according to criteria defined in the job scheduling definition.

The contents of the History Jobs file can be viewed from the History Environment screen, which is described in Online Facilities.

Note: Starting with version 9.0.18, the History Jobs File (HST) can be allocated with up to 10 million records (High Capacity file).
