IBM TXSeries for Multiplatforms is a distributed CICS (Customer Information Control System) online transaction processing (OLTP) environment for mixed language applications.

TXSeries was introduced by IBM's Transarc subsidiary in 1997 and bundled CICS version 2.1.2 with Encina, MQSeries middleware, Lotus Domino Go web server, and other software.[1]

TXSeries is a transaction server available on AIX, Linux x86, Windows Server. It shares similar design principles and some functions with CICS on mainframe. End of 2006 saw a major release of TXSeries V6.1, with DCE and Encina components removed. This brought huge simplification to the product. There is also a new graphical web-based administration console.

IBM TXSeries V9.1 allows clients to:
   1. Create RESTful APIs to extend existing applications for mobile and cloud.
   2. Extend traditional applications in Java™ Enterprise Edition (EE) and deploy them on IBM WebSphere Application Server.

TXSeries for Multiplatforms V9.1 extends the capabilities for TXSeries for Multiplatforms V8.2 and 8.1 and folds in the benefit from earlier releases along with the new capabilities listed above.

Features and benefits[edit]

• First class integration with a Java EE environment, such as WebSphere Application Server, to allow the extension of application assets in Java while retaining proven CICS assets • Ability to integrate easily into a mixed-language, hybrid cloud solution with support for RESTful APIs • Cost-effective distributed transaction processing offering for traditional language workload. • TXSeries can be scaled up to CICS TS on the mainframe, if the needs of the business grow. • Integrates data and applications in distributed solutions and enterprise systems, such as IBM CICS, IBM IMS™, IBM DB2®, IBM MQ. • Extends CICS applications to the web using CICS TG and WebSphere Application Server. • Extends traditional language applications to mobile using IBM MobileFirst platform (formerly IBM Worklight) and CICS TG • Allows applications to be hosted in a traditional datacenter, as well as hosted in cloud.

The main enhancements in TXSeries for Multiplatforms V9.1, V8.1 & V8.2 are: Modernize

  • Create RESTful APIs to extend existing applications for mobile and cloud.
  • Extend traditional applications in Java™ Enterprise Edition (EE) and deploy them on IBM WebSphere Application Server.

Improved performance

The performance of TXSeries for Multiplatforms V8.2 is improved in all areas. For example:

  • Up to five times improvement in response time, and up to 50% reduction in memory footprint while processing large data, using channels and containers over IP interconnectivity (IPIC) protocol.
  • Up to 40% improvement in transaction response time for CICS® applications written using Micro Focus COBOL.
  • Improvement in transaction throughput and multifold reduction in memory footprint for CICS applications written in Java by leveraging shared class caching in JVM.
  • Up to 40% improvement in performance for batch applications accessing VSAM files in Structured File Server (SFS).
  • Overall improvement in transaction throughput compared to previous releases of TXSeries.

These performance improvements may vary, subject to application, system configuration, and operating environment.

Enhanced application development

  • TXSeries for Multiplatforms V8.2 introduces support for COBOL-IT, for Linux™ on x86 architecture.
  • This release of TXSeries extends Micro Focus COBOL support to include Visual COBOL.
  • IBM COBOL application developers can now simultaneously debug their online CICS Applications.
  • With TXSeries for Multiplatforms V8.2, Temporary Storage Queue (TSQ) names can now be up to 16 characters.
  • Enhanced IP Sockets interface to support COBOL.
  • Support for External Call Interface (EXCI) facility.
  • Support for concurrent TCP/IP Listener programs with the implementation of the CSKL transaction.

Enhanced platform coverage

  • Support for Linux™ on x86 architecture

Improved operational efficiency

  • Real-time monitoring capability with IBM Tivoli® Monitoring infrastructure
  • Simplified administration on UNIX™ platforms by allowing non-root users to perform TXSeries administrative tasks
  • Support for passwords of greater than eight-character length for better alignment with new security policies
  • TRANCLASS feature for improved management of resources
  • Extension to networking support with Internet Protocol version 6
  • Better handling of stored XA passwords to reduce security exposures
  • Improved transaction co-relation capabilities across TXSeries regions
  • Provision of user exit chaining for better customization capability
  • Enhanced Workload Manager with simplified configuration and improved health monitoring
  • WebSphere® Liberty as a backbone for web-based infrastructure in TXSeries for better scalability

Enhanced enterprise integration

  • Improved integration with WebSphere MQ with support for CKTI and CKQC transactions
  • In-bound SOAP support with addition of PL/I as a supported language

In addition, TXSeries serviceability is improved with additional problem determination tools.

Common integration server deployment scenarios

  • As a mid-tier terminal server, which can cohost applications in Java EE and COBOL seamlessly
  • As a consolidating mid-tier terminal server, between internal customer service representatives at end-user terminals, using industry-specific graphical or screen-based interfaces to access applications and data from more than one EIS
  • As an intelligent mid-tier gateway between a Java EE application server that delivers web content to Internet users who are unknowingly accessing applications and data from more than one EIS
  • As a mid-tier integration server for applications and data residing on more than one heterogeneous EIS, as a result of consolidation within a corporation, or after a merger or acquisition, for example.
