2012

CICS Transaction Server (CICS TS) V5.1 satisfies over one hundred user requirements that help drive operational efficiencies while increasing service agility, moving you towards a service delivery platform for cloud computing.
  • Driving operational efficiencies:
    • Greater capacity is delivered through significant vertical and horizontal scalability enhancements.
    • Managed operations are provided through the introduction of policies, that deliver automated control over critical system resources.
    • Increased availability enhancements reduce the need for planned outages.
    • Deeper insight into performance and compliance information can help to tune and audit system usage.
  • Increasing service agility:
    • First-class applications enable the creation of agile services from existing assets by using a new declarative application resource.
    • First-class platforms enable the creation of agile service delivery runtimes by using a new declarative platform resource.
    • Modern interfaces enable you to build rich web experiences for critical applications. A new production-ready web container in CICS provides CICS qualities of service, and is built on the WebSphere Application Server Liberty profile for compatibility.
    • Foundational enhancements extend the core CICS capabilities.
CICS TS V5.1 also introduces a wide range of other technical and operational capabilities.

In January of 2012, IBM also introduced CICS Transaction Server for z/OS Developer Trial V4.2. This is a 'try-before-you-buy' edition of CICS Transaction Server for z/OS.


2014
CICS Transaction Server (CICS TS) V5.2 satisfies over one hundred user requirements that help drive operational efficiencies while increasing service agility, moving you towards a service delivery platform for cloud computing.
  • Service agility:
    • CICS TS V5.2 significantly enhances the portability of web applications into CICS, by upgrading IBM WebSphere Application Server Liberty Profile to Version 8.5.5 and supporting a broader set of its features.
    • Service oriented architecture (SOA) support is extended by integrating the JavaScript Object Notation (JSON) and Representational State Transfer (REST) capabilities, introduced in the CICS TS Feature Pack for Mobile Extensions, into CICS TS V5.2. This makes it easier to interact with mobile devices and mobile-optimized gateways, such as IBM Worklight Server.
  • Operational efficiency:
    • The number of supported policy thresholds is expanded to cover an increased number of threshold types, safeguarding critical runtime resources. This enables a wider range of service-level agreement thresholds to trigger automatic actions.
    • The integration of CICS applications with distributed security standards has been simplified by incorporating the Security Assertion Markup Language (SAML) support, introduced in the CICS TS Feature Pack for Security Extensions, into CICS TS V5.2. Also introduced is support for Kerberos security tokens and stronger cryptographic ciphers. SAML support is provided for both inbound and outbound use of SAML tokens, and SAML tokens can now be augmented by adding new attributes.
    • A transaction channel allows applications to be able to use containers throughout the transaction without the need to restructure COMMAREA-based programs. Performance enhancements include a reduction in 31-bit storage usage for web services and an increase in threadsafe support.
  • Cloud enablement:
    • Major advances are made in the area of cloud enablement, to enhance application lifecycle management by allowing different versions of a multi-program application to run concurrently, and simplify deployment of application updates or to easily rollback to an earlier version if required.
    • Application versioning assists with the consolidation of applications onto fewer CICS regions.
    • Platforms are enhanced to define and create new 'top down' topologies, and to add and remove regions from installed platforms.
    • Twice as many traditional CICS resources can be defined and managed in CICS bundles, compared to previous CICS TS releases.

CICS Explorer V5.2 also adds support for the new and enhanced capabilities of CICS TS V5.2.

IBM also introduced CICS TS Developer Trial V5.2 (a 'try-before-you-buy' edition of CICS TS) and CICS TS Value Unit Edition (VUE) V5.2 that offers a one-time-charge (OTC) price metric for eligible workloads that are deployed in qualified System z New Application License Charge (zNALC) logical partitions (LPARs).

IBM also updated five core foundational CICS tools (and the Optimization Solution Pack): CICS Configuration Manager for z/OS V5.2, CICS Deployment Assistant for z/OS V5.2, CICS Interdependency Analyzer for z/OS V5.2, CICS Performance Analyzer for z/OS V5.2, CICS VSAM Recovery for z/OS V5.2, CICS Optimization Solution Pack for z/OS V5.2
