...we run a mainframe (currently a z890) here for supporting large datasets on either DB2 or IMS. We have an on-call staff, who handles production support during night and weekend hours. (The mainframe is - of course 24/7/365.) The few times they asked me to do on-call, I responded by telling them that - whatever the problem is - the solution is to IPL.
They haven't asked me to be on-call again.
What's IPL?
Initial Program Load. "Control-Alt-Delete" for mainframes. Of course on big systems, you could boot from any of a variety of devices, including disk packs, tape drives etc. Generally, it would get a block of data from the selected device and then execute that data, which would then load in the rest of the app or loader.
