Hardware requirements

HCL Workload Automation for Z operates on any IBM® hardware configuration supported by z/OS Version 2.2 (program number 5650-ZOS), or later.

HCL Workload Automation for Z needs a minimum region of 8 MB below the 16 MB line; at least 32 MB must be available above the 16 MB line. The region value depends strictly on the HCL Workload Automation for Z customization and workload. For HCL Workload Automation for Z to work correctly, you might need to specify a region value of 64 MB, which gives you all the available space below the 16 MB line plus 64 MB above the 16 MB line.

In particular, a region value of 64 MB is strongly recommended when the HCL Workload Automation for Z TCP/IP or APPC server is used for remote interfaces, such as the Dynamic Workload Console, PIF, and ISPF.

Consider to increase the region size specification if the server task will normally run for a long time (several weeks or months). Also make sure that the IEFUSI exit is not limiting the region size to a value less than the one coded in the JCL.

An HCL Workload Automation for Z dialog user needs a region of 3 MB below the 16 MB line; if you want to run EQQAUDIT interactively (option 9.10 of the main menu), this number then increases to 4 MB. HCL Workload Automation for Z report programs need a region of 3 MB below the 16 MB line.

HCL Workload Automation for Z uses less than 1 KB of 24-bit Common Service Area (CSA) storage. The amount of 31-bit Extended Common Service Area (ECSA) used is approximately 30 KB, plus 2 KB per active dialog user.

A display terminal supported by ISPF Version 6.1 or later is required to invoke and run the HCL Workload Automation for Z host dialogs.

The graphic function requires a terminal supporting Graphic Data Display Manager (GDDM/MVS) Version 3 Release 2 or later.
