If a customer finds a bug in your application, wouldn't it be great if you could build, test and deploy a fix in hours or days, rather than in weeks or months? Reducing turn-around time and aiming for continuous delivery allows your organization to constantly improve and evolve the applications and services provided to customers. There's no reason why your CICS-based applications and services shouldn't be included in the continuous delivery model.
Continuous integration and CICS
Let's say you have two... [More]
In our recent blog post about the new mobile support in CICS Transaction Gateway (CICS TG) we discussed how easy it was to create a new application to access existing CICS resources. In this blog post I'll show you how I put together a sample application which makes use of the programs and data provided by the the GENAPP support pac .
The architecture of the completed solution looks like
Setting up CICS TG
Configuring the Gateway daemon for http requests
To allow the Gateway daemon to receive and process http... [More]
One of the frequent questions we receive from customers is "How can I customize the CICS Explorer GUI, for instance by removing items that confuse my internal users?"
While removing GUI items is not something we provide support for, because CICS Explorer is built on top of Eclipse technology there is an Eclipse technique you can use to hide some elements of the GUI.
In this blog post I'll walk you through some using an activity to hide a GUI item, techniques for establishing whether a GUI item might be hideable, and... [More]
It's been a busy 18 months for the IBM CICS and Problem Determination Tools development teams, keeping pace with the latest and greatest in CICS TS for z/OS V5.2 and adding lots of new capabilities as well. New releases of five core CICS Tools plus an updated Solution Pack, together with enabling PTFs (where required) for PD Tools will help you to maximize the benefits from the latest run-time release. Don't worry if you are running an earlier release of CICS - most of the new capabilities will help you too.
Here's a... [More]
The CICS Transaction Gateway for z/OS V9.1 open beta includes new capabilities enabling HTTP clients to invoke COMMAREA or Channel-based CICS programs using JSON data, while benefiting from the established high availability and instrumentation features which CICS Transaction Gateway customers already rely upon.
Based upon the WS BIND data transformation technology and tooling already used for CICS Transaction Server web services, the proven reliability and scalability of CICS TG delivers further options for robust... [More]
Using JCA with the CICS TG in WebSphere Liberty Profile
The April betas of the WebSphere Liberty Profile provide an optional feature which enables support for the Java Connector Architecture (JCA) part of the Java Enterprise Edition (JEE) specification. As this has been one of the primary methods for connecting to CICS with the CICS TG, it made sense for me to check not only that it works in Liberty, but also how to make use of the CICS TG resource adapters from applications in a remote mode topology.
Getting the beta
Many of us have used CICS Explorer to manage CICS. But did you know that you can use the underlying CICS Management Client Interface (CMCI) from your browser (or any other HTTP client)? The CMCI request structure consists of
an HTTP header with a method (GET, PUT, POST, DELETE)
followed by a URI (Universal Resource Identifier) and
an optional XML body containing details of any changes to be made to CICS or CICSPlex SM resources
To try out the examples you need to know the hostname (called yourHostName in this... [More]
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]
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.

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]
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]
