14 z/os Predictive Failure Analysis and Runtime Diagnostics SMART! PFA enables z/os system to learn from its own environment and is able to anticipate and report on potential system issues (however rare) before they can impact your business. PFA can help you avoid soft failures - multiple atypical, but legal actions can cause soft failures. PFA tracks: Common storage usage (R10), LOGREC arrival rate (R10), Frame and slot usage (R11), Message arrival rate (with z/os R11), SMF Message Arrival rate (R12), ENQ and SPOOL utilization (R13)* PFA can be customized - Ability to exclude atypical jobs from learning algorithms (R12) Autonomics PFA can automatically invoke RTD. RTD can help you reduce the time spent deciding what actions to take to resolve a problem quickly. RTD is like an experienced sysprog - can identify potentially related symptoms and causes when it appears a problem might affect the system's ability to process your workloads. RTD analyses: Critical messages, system messages, address spaces, locks and ENQ(R12), GRS and z/os UNIX System Services file system latch contention (R13*) RTD is fast delivering an assessment in under a minute, where an experienced sysprog may take up to 20 minutes. 14

15 The foundation for modern batch Function planned for z/os R13* According to IBM research, about 90% of respondents consider batch to be mission critical with the majority choosing to run it on System z. Central to batch processing is COBOL, with hundreds of billions of lines of code, COBOL assets are almost everywhere and capable of supporting billions of transactions a day. Challenge with batch: maintaining 24x7 uptime for on-line processing systems coupled with processing ever increasing data volumes in an ever diminishing batch window Function planned for z/os R13* is intended to be the foundation for developing "realtime batch" applications that enable concurrent batch and online data access. A new z/os base component, the z/os Batch Runtime environment, provides the framework for Java-to-COBOL interoperability, for transactional updates to DB2, and for sharing database connections between Java and COBOL. New Java-COBOL interoperability capabilities are designed to enable you to re-use valuable COBOL assets by developing new and/or enhancing existing batch applications with Java For example, use Java subroutines directly in lieu of Java stored procedures. Take advantage of System z specialty engines JES2 JCL enhancements are designed to make programming JCL easier, and give you more performance and more control of your batch applications. In-stream data in catalogue procedures, more options on reporting the return code for jobs, and the ability to stop and hold a job at the end of a step (not just at the end of the job) give much more granularity and control. 15

16 Simplified FICON I/O configuration NEW! z/os FICON discovery and auto-configuration (zdac) Automatic discovery and configuration for FICON disk and tape devices Reduces level of IT skill and time required to configure new devices Uses intelligent analysis to help validate server and storage definitions are compatible with each other Uses built-in best practices to help configure for high availability, helps avoid single points of failure Transparent to existing configurations and settings Invoked through, integrated with z/os Hardware Configuration Definition (HCD) and z/os Hardware Configuration Manager (HCM) Use with single systems or sysplexes No migration actions required 16

17 Addressing usability and skills Additional function planned for z/os and z/osmf R13* z/osmf support for context sensitive application launching Allow z/osmf applications to link directly to other z/osmf or Web-based apps First phase of a more seamless experience in managing z/os systems z/os Health Checker More control over scheduling. Ability to write checks / have messages that increase with severity. New checks: for zfs, also report on tape library devices that had initialization errors at IPL time DFSMSrmm - Ability to automatically correct the volume list for multivolume tape data sets New DFSMSdfp messages real-time lookup of DFSMSdfp Open, Close and End of Volume error messages SDSF JES2 no longer to requires WebSphere MQ JES2 JCL improvements - Intended to simplify the writing and reuse of, and improve the performance of JCL Additional usability enhancements planned for: DFSMSrmm, DFSMSdfp, DFSMSdss, DFSMShsm, IDCAMS, SMF, ISPF, z/os CIM Server, SDSF, IBM Tivoli Directory Server, and more 17

18 z/os R13* - Performance Improved I/O performance for z/os UNIX workloads in a Parallel Sysplex Using direct I/O with fully shared zfs file systems, true cross-system sharing of zfs across a Parallel Sysplex Direct I/O from all sharing systems, no more function-shipping Performance improvements expected for what were non-owning systems before ALSO, improved zfs availability with a new zfs internal restart function. Improved performance for any workload that copies partitioned data sets IEBCOPY updated to improve the copying of partitioned data sets (PDS to PDS only ) Constraint relief can enable you to get more work done Improved Message Flood automation Increase in scope and improved usability Get improved performance and avoid splitting catalogs with: More aliases defined to a user catalog for R13* Support for larger than 4GB catalogs with z/os R12 Additional constraint relief in DFSMSdfp, z/os Communications Server, VSAM Record Level Sharing, longer data set retention periods, extended I/O task tables, BSAM 18

19 z/os R12 - Performance for Many Key Workloads Up to 44% improvement for VSAM-based workloads (batch and online)* Up to 30-50% improvement for z/os XML System Services validating parsing* Up to 50-90% for SVC dump capture time* Up to 80% shorter DB2 9 for z/os restart time* Up to 11% performance improvement for z/os R12 XL C/C++ workloads* Processing overhead for Application Transparent -- Transport Layer Security (AT-TLS) can be improved by 30%*. Network throughput for interactive workloads can be improved by 30-50%* using the new Inbound Workload Queuing (IWQ) function, which is exclusive to OSA-Express3 on IBM zenterprise 196 (z196) and IBM System z10 servers. * Based on IBM Lab results, your results will vary. VSAM performance improvement is through the use of VSAM CA Reclaim; actual benefit may be more or less and will depend on the degree of VSAM data fragmentation and how the data is accessed. It is anticipated that VSAM key sequenced data sets (KSDS) that are severely fragmented or rarely reorganized will see the most benefit. For applications that delete a large number of records from a narrow key range and then immediately re-insert them, CA Reclaim could result in some performance degradation. z/os XML System Services validation parsing performance will depend on the amount of data being parsed and the degree of complexity of the schema. Actual SVC dump time will depend on amount of data being captured and the amount of that data dumped from auxiliary storage. DB2 9 for z/os startup time reduction is through z/os Allocation, DFSMSdfp, and GRS improvements; actual benefit will depend on number of data sets opened. It is anticipated that address spaces opening up many thousands of data sets will see more benefit. Performance improvements are based on internal IBM lab measurements, and the performance improvement of over 11% was observed using compute-intensive integer workload code generated by the z/os R12 XL C/C++ compiler with high optimization when compared to code generated using the z/os R11 XL C/C++ compiler, on a IBM zenterprise 196 server. The AT-TLS CPU consumption results were obtained on System z10, model 2097-E64. Actual AT-TLS CPU consumption improvement will depend on the amount of data being transmitted and whether the workload is interactive or streaming. Throughput gain due to this improvement in CPU consumption is likely, but would vary depending on overall utilization of the z/os image. The interactive networking throughput measurements were obtained on System z10, model 2097-E64 with OSA Express 3 Inbound Workload Queuing function. Actual benefit will depend on amount of data being transferred, presence of bulk-data traffic in the mix, and whether communication is z/os to z/os, or z/os to distributed system. 19

20 z/os Availability Enhancements VSAM Control Area (CA) Reclaim (R12) Improve application performance, storage utilization, and availability by avoiding the planned outages used for defragmenting and reorganizing VSAM KSDSs to eliminate empty Control Areas. Smart! Smart components GRS and XCF have the ability / option to automatically preserve sysplex availability by taking themselves off line before small problems can turn in to big ones. (R12) Timed Auto Reply Gives z/os the option to respond automatically to certain messages when you cannot, preventing small incidents from cascading to larger ones. (R12) Avoid JES3 re-starts with JES3 dynamic spool add (R13*) Improved channel recovery - track errors and automatically remove failing paths (R13*) zfs internal restart - automatically recover disabled aggregates in Sysplex aware mode avoiding lengthy manual system recovery process. (R13*) Concurrent service for DADSM and CVAF avoid planned outages (R13*) DADSM Dynamic exit (R13*) 20
