IBM Knowledge Center will soon become the central location for online documentation about IBM products, replacing all the separate information centers. You do not need to take any action, links to the existing CICS information centers will be automatically redirected to IBM Knowledge Center from May onwards, but you will notice some changes in the look and function of the CICS online documentation.
You can find the IBM Knowledge Center here: www.ibm.com/support/knowledgecenter/.
Why are information centers changing?
Abstract: CICS CMCI connections can only be defined manually in CICS Explorer. This is suitable if you have to create a small number of connections but does not fit if you have to define a large number of connections. This document will show you how to generate Connections.pref from an Open Office spread sheet. This article is based on CICS Explorer 5.1.1
Objective: Generate Connections.pref from Open Office spread sheet (See picture below)
How you will reach your objective: By following this guide you will define an XML... [More]
In my previous article “What is CICS Application Multi-versioning?” I described how the new multi-versioning capability in the CICS TS V5.2 open beta could be used to eliminate name clashes when hosting independently developed applications on the same CICS platform. This allows you to take advantage of the increased operational efficiency and reduce the number of regions required. In this article I will explain how use to the multi-versioning capability to increase service agility.
[7/Oct - article updated to refer to CICS TS V5.2 and some WASDev links updated]
CICS TS V5.2 includes the latest WebSphere Application Server Liberty Profile (WLP) V8.5.5 that provides features for the Java API for XML Web Services ( JAX-WS ) and the Java Architecture for XML Binding ( JAXB ). Together these technologies enable you to write SOAP web services in Java as part of a CICS application.
You may be thinking, why not use the CICS TS native web services stack as it is fast, efficient and... [More]
The Announcement Letter for the CICS TS V5.2 open beta says that “Lifecycle management of first-class applications, introduced in CICS TS V5.1, now supports multiple installed versions of applications.” What is this new capability, how does it work , and why should you be interested?
In CICS TS V5.1 we introduced the application resource with a nice long 64-character name and a proper version. So rather than just borrowing characters from an 8 character CICS resource definition name , it was... [More]
This article shows how the IBM Health Center can be easily installed into the CICS Explorer and used to create customized perspectives for monitoring CICS JVM servers. Together these two tools provide a powerful platform for profiling CICS Java applications, monitoring memory usage and garbage collection, and performing further diagnostic commands .
To follow the setup in this article you will require the following minimum software requirements:
CICS TS for z/OS V4.2 or later

A number of our users create special perspectives tailored to their company, or workflow, pulling together the critical set of views for their situation. For a single user, it's simple enough to customize the perspective and save it using the Window > Save Perspective As... menu, but it's difficult to share these between users. The correct way to share perspectives between users is by Eclipse's extensibility features.
As an example, we're going to create a CICS Web Hosting Perspective that shows the information needed... [More]
Over the past five years the CICS Transaction Gateway team have released a number of SupportPacs to support the development of applications calling CICS using CICS TG APIs. This post provides a summary of these SupportPacs, including detail on the evolution of the API for .NET Framework-based applications.
Click the links to the specific SupportPacs to find further detail and API documentation.
CA5F: IBM CICS TG 'gateway' intercept plug-in support
When we talk to customers about z/OS Explorer and CICS Explorer we get a lot of positive vibes. There's talk of how it can help their teams, how it can simplify some of their tasks, and sometimes how they want to extend it with plug-ins they already use.
When we get onto discussing how it can be deployed to their teams, the concepts sound good in theory but we've seen that people of get confused, in practice. This is compounded because of the large number of ways it can be installed (to cater for the difference needs of different... [More]
Some of you will have seen me present this picture as part of how I explain our objectives for the new Application and Platform capabilities being created in Version 5 of CICS TS. These two concepts are major foundations for our move to enable to faster and simpler deployments - as valuable outcomes in the strategic Cloud initiative.
I typically start by explaining that this is definitely a vision of the future - we're at the start of a journey to a time when this sort of scenario may be business-as-usual, but it we don't start... [More]
Electronic mail has become an effective form of communication widely used in our private lives and dealings with businesses, governments, and other organizations. For example customers now expect confirmation and status of orders, account alerts, and availability of statements to be sent within minutes via email. Email strikes a balance between the expense and delay of physical post, and the more immediate but temporary nature of SMS.
As many of today's transactions are hosted in CICS Transaction Server (CICS), it is not surprising... [More]
In CICS TS V5.1 we introduced Policy . This is a set of one or more rules each setting a threshold for resource consumption and specifying an action to be taken when it’s exceeded. You can set limits on CPU consumption and storage use as well as DB2 and VSAM file accesses. The actions CICS can take are to issue a message, abend the task or emit a system event . The last action allows you create or extend automation to perhaps send an email or SMS when an application starts behaving badly.
Hidden in the release notes for the latest CICS Explorer V5.1.1 you will see an enhancement that provides the “Ability to edit a CICS Platform project, CICS Application project, or CICS Application Binding project”. The required server-side APAR PM81540 is now available.
These new editors are a significant improvement to the user experience of working with CICS Applications, CICS Bindings and CICS Platforms so if you are interesting in the cloud enablement capability in CICS TS V5.1 please try out... [More]
Writing RESTful web services using a CICS Liberty JVM server - Part 2
My name is Daniel Fitzgerald, I'm a trainee software developer in the CICS team based at IBM Hursley UK. I've been working for the last six months on the Mobile Extensions Feature Pack V1.0 for CICS Transaction Server. As part of the project we looked at using JAX-RS, JSON and RESTful designs within Liberty.
