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

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

CPU Measurement Facility (MF) countersVM64961

CPU MF counters are a System z hardware facility that characterizes the performance of the CPU and nest–Instructions, 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 hardware–Counters are put in new z/VM monitor record
