A number of our users create special perspectives tailored to their company, or workflow, pulling together the critical set of views for their situation.

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.

Electronic mail has become an effective form of communication widely used in our private lives and dealings with businesses, governments, and other organizations.

As many of today's transactions are hosted in CICS Transaction Server (CICS), it is not surprising the need... [More]

This particular weekend, Mom required her house to be painted and as a good son should, I responded ,"Let's Git-R-Done " ...as Larry the Cable Guy would say.

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...

The first problem is identifying a memory leak and the second problem is locating the class responsible. This post will show you, how to identify and locate a memory leak in a Java program running in the JVM server in CICS. Overview One of the advantages of using Java as a programming language is that... [More]
