A customer is running a Java workload in a z/OS LPAR on a z14. Which specialty processor can help reduce the general-purpose central processor (CP) consumption of this LPAR?

Question

Options

• AzIIP
• BSSC
• CICF
• DIFL

• A
  92% (24)
• B
  4% (1)
• C
  4% (1)

Explanation

zIIP (z Integrated Information Processor) is correct because it is specifically designed to offload eligible z/OS workloads - including Java applications running under the IBM SDK for z/OS - from general-purpose CPs, reducing software licensing costs and CP utilization without changing application behavior.

Why the distractors are wrong:

• B. SSC (System Support Controller) is a hardware support controller that manages system infrastructure functions, not a workload-offload specialty processor.
• C. ICF (Internal Coupling Facility) processors handle Parallel Sysplex coupling facility operations (sharing data/locks between LPARs), not application workloads like Java.
• D. IFL (Integrated Facility for Linux) processors are dedicated to running Linux workloads - they cannot run z/OS or its Java workloads at all.

Memory tip: Think "zIIP = z/OS Information Processing" - it offloads data-intensive z/OS tasks like Java, XML, database utilities (Db2, IMS), and encryption. If the question mentions z/OS + Java + cost/CP reduction, the answer is almost always zIIP.
