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...

The following steps will enable you to create a CSV extract using CICS PA and then use the supplied sample JCL and REXX exec to convert the CSV to a format that can be used with the Mobile/zCAP Workload Reporting Tool (MWRT). Note that this version of the solution only supports CICS TS V5.1 and above because it relies on the presence of the CPUTONCP CMF field, introduced in CICS TS V5.1. Step 1: Use a CICS PA FORM as below to generate the report JCL for the CICS PA CSV extract.... [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]
It's a well documented fact that the earlier a bug is discovered the easier it is to fix. One of the challenges of writing applications to run in CICS is that you have to have a region available for running the applications in. If this is then shared with other developers you can run into issues as only one remote debugger can be attached to a JVM server at any one time. A potential solution is to write automated unit tests that run inside the development environment, but before we can do that we need to be able to use the JCICS APIs... [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.
