Issue/Introduction
Is there any documentation dealing with zHPF (High Performance FICON) activation for Datacom 15.1 EXCP datasets?
The parameter X_TEST_QA_EXCP_ZHPF cannot be found on Datacom 15.1 documentation.
Environment
z/OS
Resolution
The X_TEST_QA_EXCP_ZHPF card is obsolete and it was used for testing High Performance FICON (zHPF) in Datacom 14.0 and 15.0.
For Datacom 15.1, refer to the following page on the Datacom 15.1 documentation:
where one can read that the MUF SYSIN card for 15.1 to activate zHPF support is IO_STYLE_NEWER (it can be also issued as a console command when MUF is up).
Additional Information
As of July 2022, besides product enhancement PTF SO10697 (ENHANCEMENT IMPROVED I/O PERFORMANCE), there are other Datacom 15.1 PTFs dealing with zHPF that should be applied as well:
LU02919 - DBUTLTY LOAD FAILS WITH DB13010C I/O ERROR AFTER A DB RC
SO14100 - ENHANCEMENT IMPROVED I/O PERFORMANCE FOR DBUTLTY
SO12809 - DBUTLTY DB00817E I/O ERR - RETRY ZHPF DISABLED BUT COMPLETES
