The development, release, and timing of any future features or functionality described for our products remains at our sole discretion.

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.

Mobile scenarioConnect directly to CICS from Worklight using end-to-end JSON

A B C

DFHLS2JS to generate the JSON artefacts for the target

CICS service.

Mobile developer uses JSON schema to build a

Worklight adapter.

Frontend mobile developer calls the Worklight adapter which calls

the service hosted in CICS.


Liberty profile scenario

WebSphere Application Server Liberty profileIntroduced in CICS TS V5.1Light weight web container

• Provides Servlets and JSPs support for CICS

• Runs in a JVM server in the CICS address space

• Access to CICS functionality through the JCICS API

Existing web interfaces

developed using JSPs and

Servlets can be easily moved into

CICS

Direct access to DB2, providing

application developers with two routes to the

data

Policy scenarioDefine a policy to trigger an event when an application consumes too much total elapsed CPU time

A B CDefine the policy thresholds and trigger action that CICS

should take

Associate the policy with the appropriate platform or application and deploy

When the threshold is breached, CICS triggers an event, updating

an operations dashboard


SAML security scenario

A B C

Client requests SAML assertion from Tivoli Federated Identity

Manager or Datapower

CICS COBOL application extracts SAML containers from DFHSAML

channel

The application can add additional attributes to the assertion for

downstream components


CICS TS

Cloud application multi-version scenario

Rolling back to an older version of an

application is a simple operation - mark the version as

‘unavailable”

Versioning provides support for the

“major.minor.micro” system

Transition to newer (or older) version

Version 1.0.0

Version 1.0.1

Version 1.2.0

Version 2.0.0

Install, enable, make available

make unavailable


Cloud application multi-version scenarioA bug has been found and an urgent fix is required immediately

A B C

After fixing the bug in the code, repackage it with a new micro

version number

Once installed, switching to a new version of the application is simply a

case of making it “available”

CICS takes care of moving clients to the new version of the

application across all regions within a platform

Also available in CICS TS V5.2 via APAR PI25503

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







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

Example of Java 8 and z13 benefits


Statement of Direction: 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 insight

Additional security options

CICS TS V5.3 open betaPerformance optimizations, enhanced metrics, and additional security

Flow control to prevent HTTP requests flooding a CICS regionTCP/IP can efficiently route new work elsewhere

Pipeline processing of HTTP requests has been improvedRemoves 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 overheadThe 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

New non-Java JSON processing infrastructureProvides greater throughput with less overall CPU


HTTPRequests

Enhanced insight



Internal performance improvements in many other areas: 30 additional SPI commands have been made threadsafeExploits some of the hardware instructions introduced with IBM z9, such as STCKFCache alignment for key CICS control blocksReduced lock contention within monitoring algorithmsImprovements to MRO session management algorithms

Noticeable improvementsCICS trace facilityCICS monitoring facilityMRO connections with high session counts




Enhanced insight



Transaction tracking supports transactions star ted by the CICS-WebSphere MQ bridge

Transaction tracking identifies relationships between application tasks as they flow across CICS systemsAids problem determination, reporting and auditing

Metrics have been added to global CICS statisticsTransaction CPU time measurements captured without needing CICS monitoring to be active - allows greater insight into CPU resource usage without the overhead of collecting and processing SMF 110 monitoring records




Enhanced insight



Support for the Enhanced Password AlgorithmUses RACF APAR OA43999 for stronger encryption

Enhanced support for KerberosEXEC 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 APIcan 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
