Mike, Every shop is unique and the memory usage may depend on the workload. IBM provides a tool(zBNA) to estimate the z15 benefits of your system. If you are already collecting SMF type-16 records(SMF=FULL) then you can use zBNA tool to evaluate the benefits.
The IBM Z Batch Network Analyzer (zBNA) provides support for the Integrated Accelerator for Z Sort. zBNA has a new application, DFSORT Z Sort, which uniquely identifies DFSORT-eligible candidates and estimates the z15 benefits, using data from the current environment and does not require a z15. The new information integrates with the traditional batch information already available in zBNA. This no-charge tool is available for download from the IBM Techdocs Library web page. https://www.ibm.com/support/pages/ibm-z-batch-network-analyzer-zbna-tool-0 Thanks, Sri Hari Kolusu DFSORT Development IBM Corporation -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Ward, Mike S Sent: Wednesday, March 9, 2022 1:26 PM To: [email protected] Subject: [EXTERNAL] z15 DFSORT exploit Hello all, we are planning to apply maintenance to our z/OS 2.4 system because we are moving to a z15. DFSORT exploits the IBM Integrated Accelerator for Z Sort on z15. This PTF,provides,support for the DFSORT exploitation for the IBM Integrated Accelerator for Z Sort on z15. In order to enable the new function you must enable the new function as described in the documentation provided for this support. Even though the new function is shipped disabled, the enhancements may affect your existing DFSORT workloads. For example, the load module growth in SORTLPA and related infrastructure changes affected below-the-line storage usage which may affect your existing DFSORT workloads. If your DFSORT workloads restrict below-the-bar storage, you may encounter ICE039A conditions. This means that you will have to increase the values of parameters limiting the storage. SIZE/MAINSIZE and REGION are only examples of some but not all of the possible ways below-the-bar storage can be limited. With the installation of this PTF there may be a slight increase in the usage of memory objects, hiperspaces, data spaces, and sort work space even though the new function is disabled. My question is: Has anyone applied this maintenance, and if so did you experience any memory problems after doing so?
