Hello All,

I am not new to mainframes, but am new to Hercules, and in getting started I have some questions:

1.? Why is there no system libraries?? No SYS4.* or SYS2.*.? Was that supposed to come with the install.? If not, where can I get them?
2.? The same question applies to the compile/link utilities.? Should they be there and if not where can I get them?
3.? For jcl that involves no tapes,, super simple, what should the CLASS and MSGCLASS be?? I would normally say CLASS=X,MSGCLASS=Y.? Is it different on Hercules?? I am trying to run a compile which fails on a JCL error, but it won't give me what the error is.? I have tried JCLCHK but that is not available.

I am probably going to have more questions as I get started, but I just want to get my first compile/link/execute working.? Thanks again for all the help.

Hello Craig,

Welcome to the community!

It would help if you could tell us which MVS system you are running under Hercules. I know of four: Jay Moseley system, MVS/CE, TK4- and TK5. Is it one of those? or an other one?

Cheers,

Thank you very much for your help!? I am using MVS 3.8, TK-4, and Tom Brenneman TN3270.? I'm probably spoiled by my daytime job, which is mainframe programmer, and everything is always set up.? Thanks again.

If you install the latest incarnation of TK which is TK5.2, you will find SYS2 and others.
You need to read the docs that come with it as well as the original one's for TK4 as well as all of the update notes for more information.

SYS2 and the others are mostly related to the add-ons external from the IBM original distribution.

These docs do provide details as to what is initially set up for CLASS and MSGCLASS and what spools are allocated to what but these are changeable depending on your wants etc see check out the JES2 set ups.

I installed TK5.2.? I am trying to use TN3270 but every time I bring it up it always brings up Tk4 on the screen.? I have tried playing with 'Session' and 'Reconnect' but it always brings up Tk4.? Any ideas?? Thanks.

Did you remember to un-install TK4 beforehand OR set up environment vars to point to the TK5 version.

As I use a current version of SDL Hercules I have changed the supplied script to :

#!/bin/bash
#
#***??????????????????????????????????????????????????????????????? ***
#*** Script: mvs_ipl?????????????????????????????????????????????? ***
#***??????????????????????????????????????????????????????????????? ***
#*** Purpose: IPL OS/VS2-MVS 3.8j (tk5 unattended operations)?????? ***
#***??????????????????????????????????????????????????????????????? ***
#*** Updated: 2023/05/30??????????????????????????????????????????? ***
#***??????????????????????????????????????????????????????????????? ***
#
#
# set environment
#

MODE=`head -1 unattended/mode 2>/dev/null`
DAEMON="-d"
if [[ $MODE == 'CONSOLE' ]]; then unset DAEMON; fi
#
# source configuration variables
#
if [ -f local_conf/tk5.parm ]; then . local_conf/tk5.parm; fi
if [[ ${arch:0:3} == 'arm'?? && $REP101A == '' ]];then export REP101A=specific;fi
if [[ $REP101A == 'specific' && $CMD101A == '' ]];then export CMD101A=02;fi
#
# IPL OS/VS2-MVS 3.8j
#
export HERCULES_RC=scripts/ipl.rc
if [[ $MODE == 'CONSOLE' ]];
?? then $force_arch hercules $DAEMON -f conf/tk5.cnf >log/3033.log;
?? else
????? coproc MVS ($force_arch hercules $DAEMON -f conf/tk5.cnf 2>&1 | tee log/3033.log)
????? cat <&${MVS[0]}
????? wait $MVS_PID;
fi


I also have :

#!/bin/bash
#
#***??????????????????????????????????????????????????????????????? ***
#*** Script: mvs?????????????????????????????????????????????????? ***
#***??????????????????????????????????????????????????????????????? ***
#*** Purpose: Wrapper for the original TK5 mvs script (now named??? ***
#***????????? mvs_ipl) to work around the missing coproc capability ***
#***????????? of bash v3.x as distributed with OS X. If running on? ***
#***????????? OS X this script executes mvs_osx for special OS X??? ***
#***????????? processing. In all other cases it executes the??????? ***
#***????????? original mvs_ipl script.????????????????????????????? ***
#***??????????????????????????????????????????????????????????????? ***
#*** Updated: 2023/05/30??????????????????????????????????????????? ***
#***??????????????????????????????????????????????????????????????? ***
#
#
# set environment
#
system=`uname -s | awk '{print tolower($0)}'`
case $system in
darwin)
?? mvs=mvs_osx
?? ;;
*)
?? mvs=mvs_ipl2
?? ;;
esac
#
# execute the target script
#
exec bash -c "source $mvs"


I think I use the former script via another script that sets up some other vars as well as a VM - can't access it at the moment.

Are you running both systems at the same time? If so, it is possible TK4- holds the 3270 port for 3270 connections, while TK5 is waiting for it to be available. In that case, shutdown TK5, edit conf\tk5.cnf and change CNSLPORT to a different value, like 3279 instead of 3270, and use that port to connect to TK5.

Thanks Rene!? I switched it to 3279 and was able to get Tk5.? Thanks again.
