CA7 not at fault
CA7 has been around for many years - i was using it in the 90's. It works and performs very well, provided you know the tool and you know the environment. it is uniquely mainframe.
Not only did they give it to people who dont know how to use it nor do they know what their environment is, but they scheduled this upgrade on a tuesday. Had they done this on a saturday after midnight they would have at least had the sunday to back it out.
This is incompetence at its grandest.
It also proves... you get what you pay for.
