Data store address space – EQQFARCH

The HCL Workload Automation for Z data store is a z/OS® started task that is implemented by the EQQFARCH load module. To run successfully, this load module must reside in an APF-authorized library. It is link-edited with the AC(1) and AMODE(31) attributes.

EQQFARCH is the top module of the Data Store Started Task Control. It basically loads and calls the EQQFARMJ module, that performs the following tasks:
  • Initialization of Data Store parameters
  • Initialization, synchronization, and termination of all Data Store subtasks. In particular for the synchronization function, EQQFARMJ builds an event table to manage wait/post requests which synchronize the different subtask activity.

For more information about the subtask functions and their interaction, see HCL Workload Automation for Z data store task structure and HCL Workload Automation for Z data store subtasks.
