A hot start is a warm start of an abnormally terminated JES2 member without an intervening IPL. JES2 performs a hot start when a particular JES2 member has stopped but other systems have continued to function and have not experienced problems. When JES2 hot starts, all address spaces continue to execute as if JES2 had never terminated. Jobs that were processing on output devices are re-queued as if a $I command had been issued. Jobs on input devices must be resubmitted and lines must be restarted. Hot starts have no affect on other members in a MAS configuration.
