Web service optimizations

Performance improvements

Enhanced insight

Additional security options

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

Flow control to prevent HTTP requests flooding a CICS regionTCP/IP port sharing/SD can efficiently route new connections

elsewhere when regions are at capacity

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 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

Native CICS JSON processing infrastructureProvides greater throughput with less overall CPU than Java parserSupported with z/OS Connect pipeline and DFHJSON linkable

interfaceAPAR PI54841 provides EXEC CICS TRANSFORM API for JSONAPAR PI55897 planned to provide support for native parser with CICS

JSON web services pipeline


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

Application processing run as before

CWXN

Only run whenunable toestablishcontextin SOLS

User Transactioni.e. CWBA, CPIH

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

CICS TS V5.3 – Removing need for CWXN




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

Enhanced insight



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

Transaction tracking identifies relationships between application tasks as they flow across CICS systems

Aids 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: 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

Policing SSL levelsNew System Initialization Table (SIT) option, MINTLSLEVEL, allows

installations to specify the minimum level of Transport Layer Security (TLS) supported by CICS.

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

CICS TS V5.3New cloud and DevOps support to automate CICS deployments

Applications and bundles provide a convenient way to package and manage components, resources, and dependencies in CICS

CICS Build ToolkitCommand-line tool for automating the building of CICS projects

from Eclipse source projects created using CICS Explorer• Cloud applications and bundles• OSGi Java and Liberty profile componentsRuns on z/OS, Linux and Microsoft WindowsBundles can be built for CICS TS V4.1 and later

Variables can be used in CICS bundle partsVariables substituted using values in properties files by the CICS

Build Toolkit or the CICS Explorer when exporting manuallyEnables deployment of the same bundle to target systems that

require different resource attributes

application– Copy to staging

• Test, and run from continuous integration build server, such as Jenkins or RTC

New threshold policiesElapsed time, number of IBM MQ requests, DL/I requests, named

counter requests, and shared temporary storage requests issued by a CICS task

Total number of policy types is now 14, containing more than 40 items that triggers can be set against

A transaction ID can be set as an application entry pointDifferentiate and control users by tranid, program, or URIMAP

A transaction ID can be set as the scope for a policy

Recovery of the application infrastructure enhancedThe available or unavailable state of an application is automatically

recovered across CICS restarts

CICS TS V5.3 – Statement of DirectionJEE7 and WebSphere Liberty Profile support

IBM intends to deliver support for Java applications that exploit Java EE 7 Full Platform features when running in the WebSphere Liberty profile that is integrated with IBM CICS Transaction Server for z/OS (CICS TS).

IBM intends to deliver additional Java EE 7 components and technologies for the CICS TS hosted WebSphere Liberty profile through continuous delivery of new features in the coming months. These additional components and technologies are intended to include support for Java EE 7 Web Profile features, support for JMS 2.0 with IBM MQ for z/OS, and the ability to LINK from a CICS TS COBOL program to a CICS TS hosted Liberty application.
