The phrase alternate sysres is a part of my culture, or at least was up to March 1999. The maintenance philosophy dictated that our main system volumes operated in pairs. The active set and a maintenance set. The maintenance set would receive all changes, which required an IPL to be implemented, and once a month the IPL would occur off the maintenance set. If the IPL ran smoothly the maintenance volumes became the active set, and the previous active set became the new maintenance set. The next maintenance cycle beginning with a clone to refresh the new maintenance set from the current active set. This technique was employed to provide push button recovery should an IPL fail, there being no time to investigate failures given the number of systems being IPLed in any given night (usually into double figures), let alone the Service Level commitment to customers. I am not sure precisely if the term was directly quoted in documentation, but the process was aided by references to Alternate Master Catalogues, the use of symbols at IPL, and the splitting of Parmlib information into Common and System Dependent stuff. I hope this is of some use.
