That is no longer true. There is an option to run duplicate batch as of z/OS 2.1(?). Might be earlier.

The SYSTEM will NEVER allow you to run 2 or more batch jobs with the same name. That lock/prohibition has been There since JES was written. It been a convenient way to single thread multiple jobs with the same name. That being said you can have MULTIPLE STC's with the same name but you best be very, very careful -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Lizette Koehler Sent: Thursday, September 14, 2017 8:50 AM To: [email protected] Subject: Re: Can you run multiple jobs with the same job name at the same time on JES2? There is. It is documented in the JES2 INIT and TUNING. Go to www.ibm.com and search on JES2 DUPLICATE JOBS However, what problem are you trying to solve? When you switch this on - it will be an way of running that JES2 supports but it is not normal for JES2. It was setup with serial processing. If you run duplicate job names, you will probably hit resource contention. Everyone wanting the same dataset, for example. If you specify DUPL_JOB=NODELAY, jobs with the same job name may run concurrently with adverse effects. Make certain that this serialization mechanism is not being used in your environment before changing this parameter.
