I want to learn as quickly as possible as much as I can about z/OS and products in this operating system's environment (ISPF, TSO, etc.) Can anyone recommend a book(s) and/or training tools? I realize I'm trying to shortcut what takes professionals years to learn but, I need to be an effective support person in my new position supporting IBM z/OS. I need to become capable of supporting z/OS as a level 2 support person as rapidly as possible.
Thank you for your recommendations in advance!!
