z/OS R13 The foundation for modern batch

Interactive is manual. Batch is automatic. Gary Puchkoff, IBM Senior Technical Staff Member

Shorter batch windows! New function in z/OS helps make

batch processing more efficient Pipe data between two batch jobs

to enable these jobs to perform concurrent reads and writes

Real time batch! WebSphere Compute Grid delivers a

batch environment capable of supporting 24x7 batch and OLTP processing, and parallel computing

Expand existing COBOL applications with Java! More choice for application

development skills Leverage specialty engines!

Simplified programming! Enhancements in z/OS simplify the

development and maintenance of existing batch applications.

Enable distributed applications to access the power of z/OS batch

About 90% of customers consider batch mission critical* Challenge: Greater volumes of data and larger batch and on-line processing

windows. Solution: Need to make batch more efficient.

* IBM Market Research



z/OS R13 The foundation for modern batch Expand existing COBOL applications!

The z/OS Batch Runtime environment, provides Java-to-COBOL interoperability, for transactional updates to DB2, and for sharing database connections between Java and COBOLIdeal for processing for computationally intensive programs and extensions

Use JZOS Batch Toolkit for z/OS for efficient use of z/OS System interfaces for Java batch (IBM Java SDKs for z/OS)

Leverage specialty engines! Simplified programming!

JES2 JCL enhancements provide in-stream data in catalogue procedures, more options on setting job return codes, 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

An new REST API allows you to submit z/OS batch jobs and retrieve z/OS batch job information from distributed systems as well as z/OS systems; and is intended to make z/OS batch processing much more accessible to distributed systems and web-based processes

Shorter batch windows Allow overlapping processing for multi-volume data sets (FREEVOL=EOV) Pipe data between two batch jobs to enable these jobs to perform reads and writes

concurrently (BatchPipes, 5655-D45) Real time batch

WebSphere Compute Grid delivers a resilient, highly available, secure, and scalable runtime with container-managed services for batch applications

Capable of supporting 24x7 batch and OLTP processing, and parallel computing

* Prerequisites: IBM 31-bit SDK for z/OS, Java Technology Edition, Version 6.0.1 (5655-R31); DB2 V9.1 for z/OS (5635-DB2) or later with PTFs; IBM Enterprise COBOL for z/OS V4.1 (5655-S71) or later



Additional z/OS R13 simplification enhancements Health Checker Framework, updates

Greater ability to schedule health checks Ability for checks to raise message severity as conditions change

New health checks: Two new checks for Allocation intended to warn about potential Allocation

deadlock conditions Detects tape library initialization errors with suggestions on how to resolve.

New Migration checks for: zFS configuration options, new symbolic links, z/OS console mode of operation

DFSMSrmm, updates: New automatic recovery for missing our out-of-sequence tape volumes. For

multivolume data sets, DFSMSrmm will attempt to return the corrected list New ability to specify data sets by expiration date or VRS policy management.

Help simplify retention policies, avoid batch VRS policy management, and enable you to determine how long a tape data set will be retained

DFSMSdfp updates: New includes the explanatory text for Open, Close, and End of Volume error

conditions along with the error message. SMF dump improvement for log streams

SMF dump to log stream introduced with z/OS R9



z/OS availability enhancements

Avoid JES2 re-starts with JES2 dynamic spool migration, rapidly discontinue and drain spool volumes quickly Avoid JES3 re-starts with JES3 dynamic spool add Improved channel recovery track errors and automatically remove

failing paths (on a controller level) faster zFS internal restart automatically recover disabled aggregates in

Sysplex aware mode avoiding lengthy manual system recovery process. Automatic rerouting and recovery of z/OS system name server

resolver Concurrent service for DADSM and CVAF and DADSM dynamic exits

avoid planned outages



* I/O performance improvements measured for fully shared zFS ranged from very small to 900%, with the majority of workload conditions tested falling between 50% and 150%. The actual amount of improvement will depend on the environment (monoplex or Parallel Sysplex) and the type of file processing being done.

z/OS availability enhancementsParallel Sysplex updates

Fully shared zFS in a sysplex! Between 50% (1.5x) and 150% (2.5x)* I/O performance improvement for any z/OS UNIX

workload using shared zFS in a Parallel Sysplex Applications that use zFS, such as z/OS UNIX System Services and WebSphere

Application Server for z/OS, are expected to benefit Also: Less-disruptive recovery from most internal zFS problems (for both single system

and sysplex-aware systems) Also: A new health check for zFS configuration files

Simplified software deployment clone z/OS and software in a sysplex Eliminate the need for WebSphere MQ for SDSF Sysplex environments Automatic monitoring, takeover, and recovery to prevent CSM-constrained conditions NEW Easier to use XCF signaling protocol Updated volume information on all systems in the sysplex when DFSMSdss or

DFSMShsm Fast Replication Backup and Recovery processing complete More responsive to VIPA changes Workload balancing of IPsec IKEv2 and IPv4



1. Active Standby is the first configuration available under the GDPS/Active-Active family of solutions. Additional IBM software prerequisites required2. Recovery Time Objective (RTO) is a definition of the amount of time it takes from the initial disaster declaration to having critical business

processes available to users. Less than one hour RTO is based on use of IBM best practices and includes the time it takes to: IPL an LPAR, reconfigure disk, reconfigure coupling facility and CF structure, apply System z Capacity Back Up, as well as switching network connections.

3. All statements regarding IBM future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

Between 50% and 150%1 I/O performance improvement for any z/OS UNIX workload using shared zFS in a Parallel Sysplex

Applications that use zFS, such as z/OS UNIX System Services and WebSphere Application Server for z/OS, are expected to benefit

Between 15% and 55%2 IEBCOPY performance improvement for traditional workloads Workloads copying PDS to PDS, copying PDS to sequential, or compressing a PDS are

expected to benefit Potential for shorter batch windows*

New JCL FREEVOL=EOV parameter frees up a tape volume when the batch job is done with it

Network throughput Enterprise Extender can be improved Using Inbound Workload Queuing (IWQ), available on OSA-Express3 and OSA-

Express4S Foundation for extreme data handling and simplified storage management

Potentially improved I/O performance without the need for application changes for QSAM, BPAM, and BSAM-based workloads by leveraging High Performance FICON

Also, existing EAV functionality is enhanced with support for larger, 1 TB Extended Address Volumes (EAVs)

* Based on IBM Lab results, your results will vary.1. I/O performance improvements measured for fully shared zFS ranged from very small to 900%, with the majority of workload conditions tested falling

between 50% and 150%. The actual amount of improvement will depend on the environment (monoplex or Parallel Sysplex) and the type of file processing being done.

2. IEBCOPY improvement will depend on conditions such as: the amount of data being copied, block size, and type of IEBCOPY operationBatch concurrency for multi volume tape datasets and will depend on the amount of data being processed

CPU Measurement Facility (MF) countersVM64961

CPU MF counters are a System z hardware facility that characterizes the performance of the CPU and nestInstructions, cycles, cache misses, and other processor related

information Available on z10 EC/BC, z196, and z114 The CPU MF counter values:

Help IBM to understand how your workload stresses a CEC for future design

Help IBM to map your workload into the LSPR curves for better sizing results

Help IBM better understand your system when there is a processorperformance related problem.

z/VM 6.2, 6.1, and 5.4 can all collect the CPU MF counters from the hardwareCounters are put in new z/VM monitor record



IBM wants your CPU Measurement Facility counter data

Your data will help IBM to build a library of customer workloads Collect an hours worth of MONWRITE data

From a peak period,With CPU MF counters enabled,With one-minute sample intervals

Contact Richard Lewis at [email protected] Richard will send you instructions on how to transmit the data to IBM No deliverable will be returned to youWe will be ever grateful for your contribution
