How to force use of a single unix process to all bpxbatch calls?

I am running a program that calls BPXBATCH several times. Each call creates another task (STC) that runs the command. I want to use the same time used to create a new stc every call and that the unix task will remain active the entire job life. Is this possible? ITschak ITschak Mugzach *|** IronS

Re: How to force use of a single unix process to all bpxbatch calls?

Generally, a process started inside OMVS will run in a BPXAS initiator. On the MVS side, these are weird, in that they temporarily change their name to something like the program running (e.g. INETD8), but unlike batch initiators, there is no separate JES2 jobid for the client process. If you do

Re: How to force use of a single unix process to all bpxbatch calls?

I would need more information: - By "the command" do you mean a z/OS Unix shell command? - Why exactly do you want BPXBATCH? - Do you want another STC for each "command", or is that what you don't want? - Do you need the z/OS Unix shell itself, or is it OK to run the command without a shell?

Re: How to force use of a single unix process to all bpxbatch calls?

Kirk, A rexx exec is processing a file system. First call to bpxbatch perform ls looping on the directories listed in the root to look for specific files (ignore the logix, it was dictated by a uniprocessor and a mixture of software). I noticed that every call to unix creates (or starts) a shadow

Itschak, Looks like you want _BPX_SHAREAS=YES. But note: "If the extended attribute for the shared address space is not set, the program will not run in a shared address space, regardless of the setting of _BPX_SHAREAS. The attribute is set by extattr +s and reset by extattr -s. If the attribute

Run your silly Rexx under UNIX. Ir's simpler. On Mon, 30 May 2022 15:52:24 +0300, Itschak Mugzach wrote: > >A rexx exec is processing a file system. First call to bpxbatch perform ls >looping on the directories listed in the root to look for specific files >

Re: How to force use of a single unix process to all bpxbatch calls?

It isn't really clear to me what you are trying to do other than some variation on /bin/find and then processing the resulting list of files. Are you are trying to start multiple concurrent processes? I can't tell. For your general description, you may want to start with a main rexx exec, its

find -exec is a generally poor choice for doing something efficiently, especially on z/OS. find -exec is an extremely popular way to demonstrate a heaping dose of impenetrable syntax On Tue, May 31, 2022, at 6:05 PM, Paul Gilmartin wrote: > On Tue, 31 May 2022 15:08:57 -0500, Kirk Wolf wrote
