Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The

actual throughput or performance that any user will experience will vary depending upon many factors, including

considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage

configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results

similar to those stated here.

Manage and monitor applications and system objects locally using JMX client API, or remotely using JConsole monitoring tool.

Also, simplified process for managing log files: control maximum number of zFS logs, redirect log files to the MVS log, standardized timestamps.

* Also available in CICS TS V5.2 via APAR PI25503.

JMS (Java Message Service) support: Java SE programs in CICS OSGi JVM server can use WebSphere MQ classes for JMS, as an alternative to the proprietary WebSphere MQ classes for Java. (Not supported for Liberty JVM servers)

Easy access to WebSphere MQ for developers familiar with JMS API, CICS MQ attach has been enhanced in support.

Supported in WebSphere MQ for z/OS V7.1 and V8, with:•V7.1 with APAR PI29770 (built on fix pack 7.1.0.6) or later•V8.0 with base APAR PI28482 and fix pack 8.0.0.2 or later

•CICS TS V5.2 also supported with APAR PI32151

IBM intends that a future release of IBM CICS Transaction Server for z/OS will support 64-bit SDK for z/OS, Java Technology Edition, Version 8 (Java 8). This support will enable the use of new facilities delivered by IBM z13 which are exploited by Java 8, including 'Single Instruction Multiple Data' (SIMD) instructions for vector operations and simultaneous multithreading (SMT).

Web service optimizations

Performance improvements

Enhanced metrics

Additional security options

CICS TS V5.3 open beta : Operational Efficiency

Performance optimizations, enhanced metrics, and additional security

CICS TS V5.3 open beta delivers optimizations to the CICS Web service infrastructure

Pipeline processing of HTTP requests has been improved, removing the need for an intermediate web attach task (CWXN transaction) for most types of SOAP and JSON based HTTP CICS Web services, reducing CPU and memory overhead

The optimization can also be used for inbound HTTPS requests using AT-TLS for SSL support (by configuring TCPIPSERVICEs as AT-TLS aware)

Even for HTTPS using CICS-provided SSL, improvements have been made by removing a number of TCB switches



HTTP in CICS TS V5.3 Open Beta

HTTPRequests

Long running task on its own TCB. Must not be blocked by an individual request.

If CICS SSL* OR Web analyser program ORStatic response ORNot enough data => CWXN

Gets tran ID and user ID from URIMAP and/or AT-TLS

Start application transaction with the specific tranid and userid

Process next piece of work

SOLS

Synchronously receive body data and pass to next step in application

CWXN

User Transactioni.e. CWBA, CPIH

* But using AT-TLS for secure connection will also bypass CWXN

Enhanced Metrics


CICS TS V5.3 open beta: Operational Efficiency

Internal performance improvements in many other areas:

•Exploits some of the hardware instructions introduced with IBM z9, such as STCKF•Cache alignment for key CICS control blocks•Use of prefetch•Reduced lock contention within monitoring algorithms•Improvements to MRO session management algorithms•Further tuning of internal procedures

Improvements in efficiency give noticeable improvements in the CICS trace facility, the CICS monitoring facility, and for MRO connections with high session counts

Enhanced metrics


Transaction tracking identifies relationships between application tasks as they flow across CICS systems, and has been extended to transactions started by the CICS-WebSphere MQ bridge. This expands the scope of transactions that can use transaction tracking, to help with problem determination, reporting and auditing

Metrics have been added to global CICS statistics, including transaction CPU time measurements captured without needing CICS monitoring to be active - allows greater insight into CPU resource usage of CICS TS V5.3 open beta regions without the overhead of collecting and processing SMF 110 monitoring records





15



Enhanced metrics


New and enhanced security options:•Support for the Enhanced Password Algorithm implemented in RACF APAR OA43999 – for stronger encryption•Enhanced support for Kerberos via EXEC CICS SIGNON TOKEN command: avoids need to flow a password – applications can validate a Kerberos security token and associate a new user ID with the terminal•New EXEC CICS REQUEST PASSTICKET API can be used for outbound requests from the current task where basic authentication is required – requests an external security manager, such as RACF, to build a PassTicket

Further off-load of authentication requests to open TCBs – reduces contention on RO TCB

Automated builds

Scripted deployments

UrbanCode Deploy support

Enhanced cloud enablement

CICS TS V5.3 open beta:Cloud with DevOps

Cloud applications and bundles: a convenient way to package and manage components, resources, and dependencies in CICS

CICS TS V5.3 open beta introduces the CICS Build Toolkit – provides a command-line interface for automating the building of CICS projects created using CICS Explorer. CICS cloud applications and bundles, as well as OSGi Java components, can be automatically built from source code

Could be called as part of a script to automatically rebuild an application when a developer makes updates

CICS build toolkit supported on z/OS, Linux and Microsoft Windows; supports CICS TS V4.1 and later




CICS Build Toolkit build script example

18

Automated builds




• A built CICS project in zFS can be programmatically deployed across CICS systems using a set of scripting commands

• DFHDPLOY – new batch utility to support automated provisioning of CICS bundles, OSGi bundles within CICS bundles, and CICS applications

• DFHDPLOY commands can be used to deploy CICS bundles and CICS applications into a desired state, such as ‘enabled’ or ‘available’ as well as undeploy and remove them





19

Automated builds




• IBM UrbanCode Deploy orchestrates and automates deployment of applications, middleware configurations, and database changes. CICS TS beta plug-in for UrbanCode Deploy supports the deployment of CICS applications as part of these orchestrations

• CICS TS beta plug-in provides functions for installing and removing resources, NEWCOPY and PHASEIN for programs, and performing a pipeline scan

• Updated UrbanCode Deploy plug-in for CICS TS V4.1 and later at

• https://developer.ibm.com/urbancode/plugin/cics-ts/





20

Automated builds




Enhancements to core CICS cloud capabilities:

New threshold policies for number of WebSphere MQ requests, DL/I requests, named counter requests, and shared temporary storage requests issued by a CICS task – there are now 14 types of thresholds against which an action can be triggered

Support for transaction entry points added for CICS cloud applications (in addition to program and URIMAP entry points already provided) – scope policies to be specific to a particular transaction ID

Recovery of the application infrastructure enhanced – the available or unavailable state of an application is automatically recovered across CICS restarts
