Correct use of JCL parameters (especially the DISP parameter in DD statements) allows parallel, asynchronous execution of jobs that may need access to […]
The following are the three possible JES2 start methods: 1. WARM – This is the default start method. – WARM specifies that JES2 is to continue processing jobs from where they were stopped. – If the FORMAT option was also coded, then JES2 will ignore the WARM specification and perform […]
