Question
Which command is used to start IPL procees
A. ?killer
B. ?Shutdown
C. ?Kill
D. None
Answer
A. ?killer
Explanation
The “?killer” command is used to initiate the Initial Program Load (IPL) process on a mainframe system. IPL is essentially a bootup process that loads the operating system and prepares the mainframe for use.
The “?killer” command signals to the mainframe’s hardware to begin the IPL sequence. This involves loading critical system software from designated disk volumes into memory. Key components loaded during IPL include the system control program, I/O subsystems, and the master scheduler.
It’s important to note that “?killer” starts the IPL, in contrast to commands like “?shutdown” which are used to properly shut down the mainframe operating system. The “?kill” command mentioned in the options is not a valid mainframe command.
So in summary, to kick off the bootup process on a mainframe, the correct command to use is “?killer” which will initiate the IPL and load the operating system and key subsystems. The other command options listed relate to shutting down rather than starting up the system.
