Tags: Proceedings, 2018, SHARE St. Louis 2018

Is trying to debug in a cross memory environment making you cross-eyed, crossed-up, or just plain cross? We can help!! We'll start with the basics: What is cross memory? Why do I need it? What instructions can be used by a program to exploit a cross memory environment? We'll step you though some examples to firm up these abstract concepts. Then we'll apply this knowledge to debugging: How do I recognize that I am running in a cross memory environment in a dump? Why is this important to know as a debugger? Come join experienced z/OS L2 support representatives for a presentation that will take the cross out of cross memory!-John C. Shebey-IBM Corporation; Patty Little-IBM Corporation
