Twenty+ years ago there wasn't a problem running multiple STCs with the same name, if you could make sure there'd be no dataset contention. I remember using automation to start some STCs with a parameter that was used as one qualifier in every temporary datasetname that that STC would allocate. I think (but can't remember how) that the automation that started the STCs made sure that different values were used for that qualifier. So eg in the STC JCL there might have been //SYSUT2 DD DISP=(NEW,DELETE,DELETE),SPACE=(TRK,(5,5)) // UNIT=SYSDA,DSN=APP3.STC#TEMP. //SYSUT3 DD DISP=(NEW,DELETE,DELETE),SPACE=(TRK,(5,5)) // UNIT=SYSDA,DSN=APP3.STC#TEMP. and that instance of the STC was started with a unique T= parm. -- Jeremy Nicoll - my opinions are my own. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Running same stc in a LPAR
And for programs that do not prohibit duplicates themselves, I remember writing a short program that I would include as the top step in an STC that checked for a duplicate address space name, and would spit out a message and abend if it found another already running.

It is not the default; it has to be enabled by job class.

Re: Running same stc in a LPAR
STCs can be started with a unique name (S xxx.yyy where yyy make it unique). However, the TSC itself can block coincarency by enquing a resource exclusively. so the answer is yes, but depends on the STC.

Re: Running same stc in a LPAR
You see it more often than you think. Go do a 'd j,bpxas' or a 'd j,init', as examples. It's common and helpful for others to have duplicates, like your HSM product, for instance (not commonly DFSMShsm). You can also run duplicate batch jobs at the same time if you just feel like it; I have twenty running right now, with a thousand more sitting in the input queue.

Re: Running same stc in a LPAR
You can the same started name more than once on any lpar. Now the product itself may not allow it based on enqueues and other things, that is why you most likely got the notification that the product was already active. For our automation product we use CA OPS/MVS and he runs multiple of the same started task name on the same lpar. JES2 has nothing to do with this.
