The Business Scenario We recently had a challenge where a customer needed full end-to-end SSL/TLS encryption for communcation between IBM Team Concert, and Urbancode Deploy. They are a z/OS Mainframe customer implementing these tools for continuous Integration / continuous deployment operations. Team Concert in this case, handles dependency build (compilation) of z/OS source code (COBOL, … Read more
We have worked with several customers in the past few years, and have come to a general consensus on the minimum operation behaviors that should be enabled in your Team Concert project. These that we have listed are in additional to any you may already have (rather than a replacement of them). These also do … Read more
