Cold start

On a restart of a JES2 member, you should implement a cold start with some caution, because all job data previously on the spool volumes is lost. No other member in a multi-access spool configuration can be active during a cold start, or JES2 will end with an error message.

If you request a cold start of JES2 or have specified the FORMAT start option, an IPL must precede the execution of the MVS™ START(S JES2) command. However, an IPL is not required if JES2 was stopped by a $P JES2 operator command.
