Summary of changes for z/OS RMF User's Guide for Version 2 Release 1, as updated February 2015

RMF support for multithreading: If enabled, multithreading uses CPU resources more efficiently when a unit of work (thread) running on a core encounters a cache miss. When one thread takes a cache miss and can no longer make progress, the core will be able to switch to running a different thread that is ready to execute.

RMF support for real storage configurations of up to 4 TB in a single LPAR: RMF has enhanced SMF records 71 and 75 to enable the Paging Activity (PAGING) and Page Data Set Activity (PAGESP) reports to support real storage configurations of up to 4 TB in a single LPAR.

RMF support for new CHPID type CS5: RMF has enhanced the RMF Postprocessor CF Activity report (Subchannel Activity section and CF to CF Activity section) and the Monitor III CFSYS Report to provide extended path attributes, which include latency and degraded mode, for the CS5 CHPID type when the enhanced-reporting-of-channel-path-characteristics (ERCPC) facility is active. Physical information, such as how the CHPID maps to a physical link, adapter and port information, and the CHPID's SAP affinity, are also provided for the new CS5 CHPID type.

Data related to CHPID type CS5 is stored in SMF record 74-4.

Enhanced Crypto Hardware Activity report : RMF has enhanced the Postprocessor Crypto Hardware Activity report to provide activity measurements from the Crypto Express5S (CEX5) card configured in one of these ways:

• Cryptographic CCA coprocessor
• Cryptographic PKCS11 coprocessor
• Cryptographic accelerator

In addition, new ICSF service measurements are provided for:

• RSA (Ron Rivest, Adi Shamir and Leonard Adleman) Digital Signature Generate and Verify callable services
• ECC (Elliptic Curve Cryptography) Digital Signature Generate and Verify callable services
• AES (Advanced Encryption Standard ) MAC (Message Authentication Code) Generate and Verify callable services
• FPE (Format Preserving Encryption) Encipher, Decipher and Translate callable services

New overview conditions are provided for the Postprocessor, based on the enhanced SMF record 70-2.
