So rather than just borrowing characters from an 8 character CICS resource definition name , it was now... [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 . Requirements To follow the setup in this article you will require the following minimum software requirements: CICS TS for z/OS V4.2 or later IBM Java SDK for z/OS V7 .0 for SR6 (or... [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 to...

Click the links to the specific SupportPacs to find further detail and API documentation. CA5F: IBM CICS TG 'gateway' intercept plug-in support... [More]
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 now then...

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 the need... [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”.

Immediately, it dawned on me how Mom would pull out paint brushes when I was a small lad to teach and discipline me to pay attention to details. Well, not this time, I went to the local... [More]
In the fall of 2012, I had the opportunity to return to the United Kingdom after 36 years. My initial visits were very quick, since the United States Navy would only allow you on shore for a short period. Nevertheless, my thoughts of the UK were still centered around the days of King Arthur ...leading up to the James Bond 007 era. Then there was my remembrance of William Shakespeare, the greatest poet and playwright ever and William Wilberforce, an English politician and philanthropist that led the movement to abolish the slave trade and most...
