IEBPTPCH includes a module IEBPPCH1 which includes SIIS coding and it causes increase CPU TIME under z15 or z16.

This client migrated hardware from zEC12 to z15 and z16 with z/OS V2R1 to V2R5. IEBPTPCH CPU time increased four times after migration of hardware and z/OS. We opened a case as TS019579686 and SME recommended us to open IBM ideas as follows. From ...

Clarify and Enhance zIIP Boost Behavior Under System Recovery Boost

The System Recovery Boost (SRB) feature, introduced with IBM z15, is designed to provide additional CPU capacity during recovery operations, such as IPLs or middleware restarts. One of the core capabilities of SRB is the zIIP Boost, which is descr...

Avoid Remote VL CP Penalties By Utilizing Local Resources When Drawer Fit Fails

On IBM z16 servers, we have observed a significant increase in the cost of accessing data/memory located in a remote drawer. In certain scenarios, this can result in a notable increase in CPI, leading to an LPAR’s CPU utilization doubling -or even...

Optimize DMR to Minimize Performance Impact During Drawer Swaps

On IBM z16 servers, we have observed a significant increase in the cost of accessing data/memory located in a remote drawer. In certain scenarios, this can result in a notable increase in CPI, leading to an LPAR’s CPU utilization doubling -or even...

Enable System Recovery Boost for DMR Events Triggered By Drawer Swaps

On IBM z16 servers, we have observed a significant increase in the cost of accessing data/memory located in a remote drawer. In certain scenarios, this can result in a notable increase in CPI, leading to an LPAR’s CPU utilization doubling -or even...

Allow System Symbols in PAGENT Konfiguration files

Currently, it is not possible to use system symbols in the PAGENT configuration files. It would be advantageous if it were possible to use system symbols in the configuration to identify system specific configuration files. This is important when ...
