Secure and fast CICS transactions

IBM® CICS® Transaction Gateway is a connector for enterprise modernization of CICS assets. It empowers various application platforms to incorporate CICS, including Java® servlets, applets, Microsoft™ .NET framework based applications, C and COBOL applications. CICS Transaction Gateway furnishes application programmers with APIs and offers the best characteristics of administration with JEE application servers.

IBM CICS Transaction Gateway (CICS TG) includes these three offerings:

  • CICS TG Desktop Edition
  • CICS TG for Multiplatforms
  • CICS TG for z/OS®

CICS TG for Multiplatforms v9.3 provides readily deployable CICS TG containers based on Red Hat® Universal Base Image which can be deployed across cloud platforms.

Deploy on cloud

Deploy and manage dockerized CICS TG Multiplatforms instances on the cloud of your choice, using a consistent deployment toolchain, and improve DevOps efficiency.

Reduce mobile enablement costs

Use JavaScript Object Notation (JSON) web services without modifying existing environments to minimize risk and cost and retain high availability and scalability.

Connect valuable CICS assets

Connect virtually everything to CICS applications and servers with programming and deployment features for distributed platforms, including Java, Microsoft .NET, C/C++, C#, Visual Basic and COBOL.

Security and availability

Exploit CICS high availability infrastructure and increased security with JSON Web Tokens (JWT), Secure Sockets Layer (SSL), identity propagation and user authentication security.

Optimize performance

Achieve end-to-end transaction tracking and performance monitoring with IBM Z Application Performance Management Connect (zAPM). Gain insight into active workloads and improve statistical proficiency.

Match today’s skills

Bridge the skill gap between UNIX/Linux, Microsoft Windows, Java-based application development platforms and IBM Z® systems.

Non-invasive connectivity

No changes to CICS applications and minimal CICS definitions are needed to achieve greater CICS connectivity.

CICS Transaction Gateway details
Fast, simple mobile enablement

Enables simple and rapid mobile integration of your enterprise IBM® CICS® Transaction Server, CICS TX or IBM TXSeries® environment. You can build on your existing architecture to quickly provide mobile connectivity to back-end systems with JSON web services.

Availability and scalability

Uses a highly available gateway with policy-based, sysplex-wide dynamic server selection. Workload Partitioning, XA transactions and 64-bit Java® 8 enable remote client applications to exploit a CICS high availability infrastructure.

Transaction tracking across IBM CICSplex

Tracks user requests from point of origin across the CICSplex® with support for problem determination and performance optimization. Performance management, monitoring and troubleshooting can be provided by IBM Tivoli® OMEGAMON® XE for CICS on z/OS®.

Containerized instance

Provides readily deployable CICS TG container based on Red Hat® Universal Base Image which can be deployed across cloud platforms. This enables simplified DevOps pipeline and ease of maintenance through rolling updates ensuring zero downtime.

64-bit support

Operates as a 32-bit or 64-bit address space. With 64-bit address space, the Gateway daemon can process workloads with larger channels and can use more connection manager and worker threads without exhausting address space resources.

Instrumented administration

Features monitoring and statistical facilities, giving planners and systems administrators insight into active workload patterns. Usage statistics are written in SMF type-111 record for offline analysis using IBM CICS Performance Analyzer for z/OS and are available in XML format for easy consumption and analysis.
