The IBM Processor Capacity Reference for z Systems (zPCR) tool has been changed to support the new z/OS workload categories. Note: Capacity Planning Tool (GA Level) for z13 and zBX Model 4 include zPCR, zTPM, zCP3000, zBNA, zSoftCap, zTPM, zSCON.Incorrect Answers:B: The zCP3000 VM Extract Utility (CP3KVMXT) reads CP Monitor data and generates an Enterprise Data File (EDF) of system and workload related measurements for input into zCP3000. It supports VM running as native or in a partition. It can be used to model interactive VM workloads or workloads under guest operating systems such as Linux.C: IBM z Systems Batch Network Analyzer (zNBA) can be used to analyze client-provided System Management Facilities (SMF) records to identify jobs and data sets that are candidates for zEDC compression, across a specified time window, typically a batch window.D: zSCON is used for OEM Server Consolidation onto System z.

With SMC-R, System z network capability takes a new leap, strengthening performance for sharing data and reducing data transmission network overhead. The new System z® RDMA over Converged Ethernet (RoCE) feature — 10GbE RoCE Express—enables industry-standard RDMA capability on the System z platform. As an RDMA-capable network interface card (RNIC), it can transfer data using direct memory-to-memory communication, reducing the CPU overhead of the networking software stack. SMC-R provides application transparent exploitation of this new RoCE feature reducing the network overhead and latency of data transfers, effectively offering the benefits of optimized network performance across processors. This breakthrough also lowers the CPU cost associated when moving large amounts of data. Incorrect Answers:B: Using the zEnterprise Data Compression (zEDC) enhancements.This enhancement allows storage administrations to exploit zEnterprise data compression (zEDC) for non-VSAM compressed format data sets. Unlike previous compression types, no separate dictionary needs to be created, as zEDC compression hides the dictionary in the data stream. A new dictionary starts in each compression unit. The system can decompress the segment as is. C: OSA-Express is an integrated hardware feature that provides direct connection to clients on local area networks (LANs). The OSA-Express feature plugs into an I/O slot just like a channel card. Fiber-optic cable connects the OSA-Express feature to the network.References: https://www-01.ibm.com/software/network/commserver/SMC/

Storage protection keys cannot be altered by application programs. There is no way, using the storage protection function, for a normal application program (not an authorized program) to protect part of its virtual memory from other parts of the application in the same address space. Note: Mainframe hardware has a storage protection function, which is normally used to prevent unauthorized alteration of storage. Storage protection is also used to prevent unauthorized reading of storage areas, although z/OS protects only small areas of storage this way.Storage protection works on 4K pages. It deals only with real memory, not virtual memory. When a page of virtual memory is copied from disk to a free page in main storage, z/OS also sets an appropriate storage protection key in that page of main storage. Storage protection was much more significant before multiple address spaces came into use. When multiple users and jobs were in a single address space (or in real memory in the days before virtual memory), protecting a user's memory from corruption (or inappropriate data peeking) was critical. With z/OS, the primary protection for each user's memory is the isolation provided by multiple address spaces. References: https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.zsecurity/zsecc_066.htm

GDPS/PPRC has the following attributes:Continuous Availability solution for planned and unplanned outages Near transparent Disaster Recovery solution Recovery Time Objective (RTO) less than an hour Recovery Point Objective (RPO) of zero (optional) Protects against localized area disasters (distance between sites are limited to 175 km fiber) Incorrect Answers:A: GDPS/Active-Active is capable of: Disaster recovery solution forDB2 and IMS data  Application level granularity  Site switch in seconds (once the event was detected)  RPO in seconds (with the ability to issue reports that can be generated showing orphaned data) B: GDPS/Global Mirror can provide: An end-to-end business continuity and recovery solution  Recovery Point Objective (RPO) is designed to be as low as five seconds  Recovery Time Objective (RTO) is designed to be under two hours C: GDPS/XRC has the following attributes: Disaster recovery solution  Recovery Time Objective (RTO) between an hour to two hours  Recovery Point Objective (RPO) less than two minutes, typically 3-5 seconds Etc. References: https://www-03.ibm.com/systems/z/advantages/gdps/offerings/

zSCON is used for OEM Server Consolidation onto System z. Incorrect Answers:B: zBNA is an IBM System z Batch Network Analyzer Tool.zBNA is a PC-based productivity tool designed to provide a means of estimating the elapsed time for batch jobs solely based on the differences in CPU speeds for a base processor and a target processor, the number of engines on each system, and system capacities; data sharing is not considered. zBNA provides powerful, graphic demonstration of the z/OS batch window. C: The zCP3000 VM Extract Utility (CP3KVMXT) reads CP Monitor data and generates an Enterprise Data File (EDF) of system and workload related measurements for input into zCP3000. It supports VM running as native or in a partition. It can be used to model interactive VM workloads or workloads under guest operating systems such as Linux.D: zPCR is a processor Capacity Reference for IBM System z.zPCR is a PC-based productivity tool under Windows. It is designed to provide capacity planning insight for IBM Z and LinuxONE processors running LPAR configurations with various workload environments under z/OS, z/VM, z/VSE, KVM, Linux, zAware, zACI, SSC, and CFCC. Capacity results are based on IBM's LSPR data supporting all IBM Z and LinuxONE processors including the new IBM z14 and LinuxONE Emperor (3906) processor families. References: https://www-03.ibm.com/systems/data/flash/dk/resources/LSU/LSU_2014_CPS_Tools_Overview.pdfhttps://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS1381

RoCE Express provides an RDMA capable network adapter providing access to RDMA over Converged Ethernet (RoCE). RoCE provides an optimized network interconnect for System z communications. Along with RoCE Express, z/OS provided a new RDMA based solution called Shared Memory Communications over RDMA (SMC-R). SMC-R is a sockets based solution providing transparent access to RoCE for TCP sockets applications over standard Ethernet.   The IBM System z13 introduces the capability to share (virtualize) the 10GbE RoCE Express feature among multiple (up to 31) LPARs (or z/VM guest virtual machines) using standardized PCIe virtualization (SR-IOV) technology. When RoCE Express is exploited by z/OS with SMC-R, the combined solutions provide two key value points: Improved latency that can provide improved transaction rates for latency sensitive transactional based workloads, and  Lower CPU cost for workloads that transfer larger payloads (i.e. analytics, streaming, FTP, big data, data replication, web services, etc.) References: https://www.ibm.com/developerworks/community/blogs/IBMCommserver/entry/ibm_system_z_10gbe_roce_express_virtualization?lang=en

The capabilities of running heterogeneous environments on a System z platform and the IBM MobileFirst framework enable an organization to fully support a mobile strategy. The mobile environment, representing the System of Engagement, can integrate with existing back-end core transactional services and data on the System z platform, representing the Systems of Records. The products that are available within the MobileFirst framework can deliver the runtime environment, mobile device management, security, analytics, and development of the application and data platforms in a mobile environment on the System z platform. Figure: End-to-end security checkpoints    MEAP server is protected by a security gateway. The mobile client must authenticate and validate credentials upon encountering the gateway. Note: CICS stands for "Customer Information Control System." It is a general-purpose transaction processing subsystem for the z/OS operating system. CICS provides services for running an application online, by request, at the same time as many other users are submitting requests to run the same applications, using the same files and programs.References: http://www.redbooks.ibm.com/abstracts/tips1162.html?Open
