Recently (past few months) I dimly recall seeing an add-in package for MVS 3.8 which used commands like *Q on something like the CBT site.

It reminded me of (and may have been) a third party product that I saw when my 1980's employer trialed? but didn't buy.

Does anyone remember such package from the olden days, or even better know where it is now?

I had various issues with SYSCPK install and contents.

First, the changes to the JES2 procedure:

• #1 with a bullet
• This (as suggested on ) won't work:
  ??? S JES2OLD
  JES2OLD is not a registered subsystem, and thus the START command will hang.
  
• The JES2 procedure is not modified in a consistent style with the preexisting statements:
• SYSC.PROCLIB was hardcoded, unlike SYS1.PROCLIB and SYS2.PROCLIB.?
  
• When combined with #1 above and a user mistake by me (!), my recovery entailed restoring from my nightly backups.?
  
• The preferred (and recoverable from) method of adding the PROCLIB would have been:
• Adding parameters PC= and VC= (for volume) to the new library
• I would also suggest also use of UNIT=SYSDA, not UNIT=3350.
  
• SYSC.PROCLIB was in front of SYS1.PROCLIB
• This is not acceptable (not on my system!), and a bad practice in general.? End of the (DD) line, please.
• You could add an alternate PROCLIB DD (/*JOBPARM PROCLIB=SYSC?)
• Are there duplicate names between SYS1.PROCLIB AND SYSC.PROCLIB?
  
• On a system with dynamic PROCLIB support, is adding SYSC.PROCLIB directly to JES2 needed at all?? (At cost of an additional line of JCL, of course.)
  

SYSC.LINKLIB has multiple minor issues:

• The library seems to be dumping ground for multiple module types; I would suggest it be audited and replaced with:
  
• A library for executable language components (under the current name?)
• Is there a summary of changes for modules which also in SYS1.LINKLIB?
  
• A library for executable utilities
  
• A library for linkable subroutines
  
• Adding SYSC.LINKLIB with its 905 members (SYS1.LINKLIB only has 121) to the APF authorized list is somewhat cavalier.?
  
• Is there a summary of what modules need authorization (and why)?
  
• I would think once reorganized, only the utilities library needs APF authorization?
  

And finally, the VATLST modifier didn't detect SYSCPK was already added to VATLST00, and inserted a duplicate entry.? As (I think) that was the only line modified, the entire step should have been skipped. (Do the other steps have duplicate changes issues as well?

Can't help with the SMF
exit, but must complement the sig...

The timeout exit is IEHUTL. There is a sample for IEHUTL in SYS1.SAMPLIB.? It's enabled by the SMF member of SYS1.PARMLIB.

As I recall, it was modified at my first employer (read: long ago and far away) so that JOBs pulled a S522 ABEND after the configured amount (15 minutes?) but TSO users had longer (an hour?)

Is an active version of IEHUTL installed by default?? If so, where do the IEHUTIL source and object live?

No IMON: not present, or not working? I don't recall have to fiddle with it (except possibly adding a PROC so I can start it from the console w/ a dedicated terminal, bypassing TSO, but even that may have already been done).

IMON doesn't work from a TSO command line.? But it DOES work from RPF.

IMON has multiple names is SYS2.CMDLIB, none of which are IMON.

I didn't worry about it because I knew it had been updated since TK3UPD was packaged and so I knew I needed to reinstall it.

Working as designed.

AKA: The stupid user (me) rides again.? :-)

In the 'good' trace, pr3287 is connected, waiting for the host to send data.

In the 'bad' trace, pr3287 connects, the host breaks the connection, pr3287 waits five seconds and tries again, forever.

So when x3270 connects with a bad group, the following is a server (Hercules) side message reported (which pr3287 does not seem to receive):

>? Connection rejected, no available 3270 devices in the xxx group

I think part of my problem is that it doesn't probably need a -reconnect for a valid configuration; the printer won't drop after each job.? Without the reconnect, it would not tweak Hercules multiple times.

The basic TN3270 protocol does not allow the host to send any sort of diagnostic saying why the session was disconnected; it just disconnects. With the time delay, the net load on the workstation and the host for this is diminishingly small.

Well, the host is being acting hammered.? Trust me. ?

Is there some other behavior you would prefer?

I'd like the host to not act hammered.? Not pr3287's fault.?

I would like the same clear message to be sent to the printer.

(bcc: Paul Mattes so he can whack pr3287. "Paging Paul Mattes" ...)

I've got MVS 3.8 up at the TK3 UPD level humming. I have QUEUE and RPF updated and SPY working. (I don't have IMON yet). WATFIV is there. JRP is running (doing nothing), and I've migrated my personal files from my bastard system TK3.

Silly me, I got fancy and tweaked things ...

... and performance went completely to hell. Utterly. So bad I spent Saturday evening writing a SUBMIT EXEC to submit jobs from my 4361 VM test system to MVS because I couldn't stand the 4 seconds or worse just to close the editor under MVS.

I could not. tell. why.

I blamed shared spool, I blamed my cats, I blamed everything. So I simplified. I ripped things out, one by one. And finally, I found it.

What I had done is connect a 3287 printer for use with JRP via the command:

 pr3287 -reconnect -command cat -V PRT@hercules:3278

This was correct, but I had no PRT label on my 3287 devices in hercules.conf. x3270 bails on this problem with a no device available error, but it seems pr3287 trundles along and connects to any old device. Hercules and pr3287 do NOT play well after this.

(It was Hercules with the issue, not VTAM or JRP. Neither were shown to be taking CPU in QUEUE.)

After correcting the devices in hercules.conf and restarting ... the biblical performance issue went away.

Yet another update:

6. The SYS1.PARMLB(SNAACT) member has to be modified to handle the new terminal. Byt why doesn't my changes have any effect - still uknown.

This turned out to be a completely different file responsible for this, the SYS1.PARMLIB(STARTSTD). Removing references to the now removed terminals solved the problem, also adding the one terminal that I wanted to have in my system, the N07L21. Haven't figured out the use for SNAACT and SNAINACT, really though.

7. It is possible to run the command from SNAACT in the console. V NET,ACT,ID=N07L21,LOGON=SNASOL,LOGMODE=MHP3278E (choose whatever ID in your setup)
8. Login works fine, but for some reason logoff and doing the subsequent disconnect of the TN3270 client make the PU fail! Why? Still researching that. Possibly related to 7? Or a problem in comm3705?

Chatted with Max Parke over mail and he suggested that making a few functions inside the comm3705 module into dummies would solve it and it indeed worked fine. So no more crashes when disconnecting the TN3270.

I have written a more in-depth article here :?

Started to look at simple SDLC implementation to run in the STM32 chip to be able to bridge to SDLC. First thing is to get it to send just a SNRM frame to the Informer 213 terminal and see what it responds.
Interfacing the STM32 gadget to Hercules will either require patches to the comm3705 module or possible a new comm3704 module that just focus on connecting to real terminals, being it BSC or SDLC.
