The zIIP Exploitation Feature (ZEF) is designed to offload CPUtime to the System z Integrated Information Processor (zIIP), a special-purposeprocessor integrated into the System z server platform infrastructure. By freeing up the general purpose processor (CP), the efficiency ofenvironments where CPU-intensive activities are being performed, …
• z/OS Communications Server exploits the zIIP for portions of internet protocol security (IPSec) network encryption and decryption. z/OS Communications Server also exploits zIIP for select HiperSockets ™ large message traffic. z/OS Global Mirror enables DFSM S.
Answer : Customers who have installed the z/OS and DB2 V8 zIIP support software can set the SYS1.PARMLIB(IEAOPTxx) parm PROJECTCPU=YES. With this setting the RMF Workload activity report and DB2PE Accounting report IIPCP field will show the projected zIIP eligible CPU information.
PK18454: DB2 Z / OS EXPLOITATION OF THE IBM SYSTEM Z9 INTEGRATED D/T2094 INFORMATION PROCESSOR (IBM ZIIP ) FOR DRDA THREADS. A fix is available. Obtain the fix for this APAR. … For more details on the use of the z / OS zIIP related parameters, refer to the z / OS MVS Initialization and Tuning Reference. DDF server threads processing SQL requests can …
1/30/2019 · Many z / OS -provided functions cannot run on a zIIP . There is a very significant overhead cost associated with switching back and forth between zIIP and non- zIIP processing. In initial tests cases run by Alebra, we found that the overhead to switch between general purpose engines and zIIP engines was larger than we anticipated, even when using …

z / OS XML System Services exploitation of zIIP z / OS XML System Services (a high speed, low latency XML parser in the base of z / OS ) is enhanced to take additional advantage of zIIPs. Specifically, all validating and non-validating parsing conducted by z / OS XML System Services executed in enclave SRB mode can be eligible to run on the zIIP .
