We’ve blogged before about starting the CLM components on Linux/Unix. Now let’s talk about staring it (and stopping it) on Windows platforms. The vast majority of the servers we deploy to are Linux. It’s just plain easy to install and configure everything via command line (certainly after many years of experience). However, Windows is (are?) … Read more

They can also be configured to have multiple filter strings such that they can display datasets or portions of datasets … Read more
During some courseware authoring I discovered a poorly known (but sufficiently documented) feature in Rational Developer for IBM i (and also available in IBM Developer for System z). Both tools use the LPEX editor as the default editor for source (although IDz has dedicated editors for COBOL, JCL, PL/I, and C/C++). The LPEX editor has … Read more

There is a strong desire to modernize the development and operations of mainframe systems (zDevOps), to increase business agility, improve customer satisfaction, accelerate business value delivery, and to improve developer job satisfaction. One of the areas to … Read more
In a recent project for a z/OS customer, we had to create some custom scripts to kick off a Rational Team Concert Promotion definition. This is a special type of build definition found in the RTC Enterprise Extensions, and is used for promoting change sets from one stream to another, by their attachments to work … Read more
