All - Please don't misinterpret my prior post. It was strictly a comment about the non mainframe community's lack of knowledge about mainframe systems. I have seen many large scale (5,000+ TPS full financial transaction) systems on Unix using Java. These are 7/24 systems processing Credit Card transactions. The application developers, operating systems programming languages are all working just fine. These are 'raised floor' environments just like a typical z system would have. The other way to look at it is my lack of knowledge about Robotic and Device control operating system and software. Those programmers are in the same boat as us. "No one understand what we have and how good it is." Unless and until people have worked in both (or more) sides of a field it is tough to understand the related nuances. When working with colleagues from a different branch of the field it will always take longer to get an idea across. It is just not possible to communicate decades of experience in a few short meetings or during the length of a single project. It takes years.
