I have set FLAG as 1 and I am execpting ARG value should be DEV only. But am getting as ARG= DEV + CLIENTID
000023 // FLAG=1
000026 // IF (&FLAG=1) THEN
000027 //SET1 SET ARG=DEV
000028 // ELSE
000029 //SET2 SET ARG=DEV+&CLIENT
000030 // ENDIF
It mean JCL assign the value in RUNTIME (before checking the IF Condition).
Please help me to understand.
Thanks!

What #hogstrom said is correct. The JCL IF statement tests Step Return codes and not Variable values:
//IFBAD IF (ABEND | STEP1.RC > 8) THEN
Following on from what he said you can use a variable in an include statement
Include With variable
// INCLUDE MEMBER=OPT&FLAG
and setup members in the proclib
MEMBER=OPT1
// SET ARG=DEV
MEMBER=OPT2
// SET ARG=DEV+&CLIENT
You have to setup an include for every possible value of &FLAG and it is very long winded for one SET. It is more commonly used when you can set lots of variables like:
// INCLUDE MEMBER=ENV&ENV
where &ENV=PROD \ TEST etc
Your case
Do not use flag, just set the variable:
// SET ARG=DEV
or
// SET ARG=DEV+&CLIENT
There is some good information in the JCL Manual to understand the purpose of the IF/THEN/ELSE purpose.
Here are a few bullets from the manual:
The IF/THEN/ELSE/ENDIF statement construct does not conditionally control the processing of JCL; rather, it conditionally controls the
execution of job steps.
The result of processing an IF/THEN/ELSE/ENDIF statement construct, once determined, remains unchanged regardless of the outcome from
running any remaining steps in a job. The system does not reexamine
the original condition at any later job step termination, either
normal or abnormal. See Example 9.
The system allocates all DD statements defined to a step if the execution time evaluation of the relational-expression determines
that a step is to be executed. All data sets defined on DD statements
in the job must be available at the time the job is selected for
execution.
You can nest IF/THEN/ELSE/ENDIF statement constructs up to a maximum of 15 levels. You can specify symbolic parameters on
IF/THEN/ELSE/ENDIF statements provided that they resolve to one of the
supported relational-expression keywords. Any other symbolic
parameters, even if accepted by the system, are not intended or
supported.
What your doing seems logical, but, its not the intended purpose of JCL SET and conditional logic.
In your case, the last SET executed is what is used and why your seeing the DEV + CLIENTID

I have a JMeter test where a CSV file containing multiple rows of comma separated values example:- internalID,drivername, usreg,canadareg. I am basically using the CSV file to compare the values with the database table values. To compare the values to database values, I am adding a JDBC request with a query 'select internalID,drivername,usreg,canadareg from data where internalid ='${internalID'}' and providing the variables names to store the column data result. I use the groovy JSR233 and call the variables names in the script by declaring String a = vars.get("dintID_${counter}") where dintID is the variable name provided in the JDBC . The issue is when I run the script the first line of data in CSV files gets executed successfully, then the second line data in CSV file is passed to SQL statement correct, however the vars.get("dintid_${counter}") always stays at previous record meaning it does not go to next internalid(dintID). I have checked that my counter is incrementing. No idea how to resolve the issue. Does anyone know what mistake I am doing.
If you take a look at JSR223 Sampler documentation you will see that:
The JSR223 test elements have a feature (compilation) that can significantly increase performance. To benefit from this feature:
Use Script files instead of inlining them. This will make JMeter compile them if this feature is available on ScriptEngine and cache them.
Or Use Script Text and check Cache compiled script if available property.
When using this feature, ensure your script code does not use JMeter variables or JMeter function calls directly in script code as caching would only cache first replacement. Instead use script parameters.
So if the counter is a JMeter Variable - it will always be the initial value and it won't increment on subsequent iterations.
So you need to change the line to:
String a = vars.get('dintID_' + vars.get('counter'))

I have to order few jobs in control m from different scheduling tables. this is manual task so i want to automate it using rexx.
I found below in 'Order or Force under Batch, REXX or CLIST' section of 'CONTROL M USERGUIDE'
EXEC CTMAPI PARM=‘ORDER variable’
I could not find syntax to call CMTAPI using rexx.
ADDRESS 'LINKMVS' is the equivalent of // EXEC PGM=something,PARM='whatever' in REXX. I don't know what the variable is supposed to be, but since this is Control-M, I am going to assume job name. A very simple example:
say 'Enter name of job'
pull jobname
parmvar = 'ORDER' jobname
`ADDRESS 'LINKMVS' 'CTMAPI parmvar'
Please note that for LINKMVS, the variable name goes inside the string passed. The LINKMVS environment substitutes the variable automatically. For example, if I entered MYJOB to the prompt, LINKMVS will build a PARM string of `ORDER MYJOB'. This is the exact equivalent of
// EXEC PGM=CTMAPI,PARM='ORDER MYJOB'
This IBM® Knowledge Center page for the z/OS 2.3 TSO/E REXX Reference manual shows several examples of calling a program in the same manner as // EXEC PGM=,PARM= (item 1). Items 5 through 9 show different ways of using ADDRESS 'LINKMVS'; note how variables are treated in each example.
After suggestions from NicC, zarchasmpgmr and few research, finally i am able to order job with CTMJOB utility. I searched for the loadlib and called TSO using REXX.
/*****REXX*******/
ADDRESS TSO
"CALL 'MY.IN.LOAD(CTMJOB)'
' ORDER DSN=MY.SCHED.LIB TABLE=SCHDTBL,
JOB=JOBNAME,DATE=DATE'"
EXIT
Details found in INCONTROL for ZOS utilities guide. This document was very useful.

I am passing command line parameters to gatling script.
This works and executes my test in Windows operating system:
set JAVA_OPTS="-DuserCount=2 -DflowRepeatCount=3 -DdefinitionId=102168 -DtestServerUrl=https://someURL -DenvAuthenticationHeaderFromPostman="Basic UWRZm9aGwsxFsB1V7RXK0OlB5cmZvcm1hbmNldGVzdDE="
It works and takes input which is passed
**********************INPUT*************************************
User Count ====>> 2
Repeat Count ====>> 3
Definition ID ====>> 102168
Environment URL ====>> https://someURL
Authentication Header ====>> Basic UWRZm9aGwsxFsB1V7RXK0OlB5cmZvcm1hbmNldGVzdDE=
***********************************************************
I want to do this same thing on Linux System.
While if I use this command in Linux then it throws error or takes Null or Binary values as input
(Passing arguments with ./gatling.sh)
JAVA_OPTS="-DuserCount=2 -DflowRepeatCount=3 -DdefinitionId=102168 -DtestServerUrl='https://someURL' -DenvAuthenticationHeaderFromPostman='Basic UWRZm9aGwsxFsB1V7RXK0OlB5cmZvcm1hbmNldGVzdDE='" ./gatling.sh
Gives this error,
GATLING_HOME is set to /opt/gatling-charts-highcharts-2.0.3 Error:
Could not find or load main class
UWRZm9aGwsxFsB1V7RXK0OlB5cmZvcm1hbmNldGVzdDE='
Here the problem is the space given in argument of -DenvAuthenticationHeaderFromPostman='Basic UWRZm9aGwsxFsB1V7RXK0OlB5cmZvcm1hbm='.
What is the solution?
The problem is that the $JAVA_OPTS variable is probably not surrounded by quotes. See this question: Passing a space-separated System Property via a shell script doesn't work
The gatling guys clearly forgot to do that.
I would file a bug and/or just edit gatling.sh.
Ideally though you might just want to consider seeing if Gatling takes a properties file or some other way to configure.
I'm using Uno choice plugin to select parameter values based on previous selections.
(This plugin helped me to reduce parameter count. I can reuse same parameter for multiple platform based on the platform selection)
I used the groovy script to select parameter values.
But it takes too much time to load parameters.
Is there any way to speed up this process?
I had faced similar issues and I was also using groovy scripts to cal shell scripts.I did the following things to reduce time:-
When you click on build with Parameters all task(scripts run at once together) are performed at once.
Use else conditions properly.
Also use Fallback script.
For eg:-
you have parameters such as
1) country
2) state
3) city
each parameter depends on the previous values.
1) Try to only display contents on Jenkins front-end.(cat command).
2) Call a script if only it matches valid values in the previous parameter.
3) minimum on the fly scripts.
4) optimize delays/sleep according to your load time.
5) Remove any extensions whether in chrome/Firefox.
5) Try using the same page in incognito mode.
6) If options are invalid through invalid option without going into any computation.
7) Uninstall plugin which are not required.
Will add more suggestions as I find.
I would request you also to please update if you find any method to optimize time.
Bash question!
so I have n arguments, and for each argument I'd like to to do a for loop and assign variables to hold characteristics of each argument. for example I have a script that runs in a continuous while loop and looks at user activity in my network... this is a simple outline of what my problems are:
while true
for argument
do
# build an array to hold times
"$user"_times =()
# set a boolean value
"$user"_boolean=true
if [ ""$user"_boolean" = true ]
then
echo $user logged on
"$user"_times+=( timestamp )
fi
done
done
exit 0
the real script will look at user activity, update the boolean based on certain user behavior, and log some user activity info in the array- but I'm trying to get this to work so I can add the easy meat. what should the syntax be? I'm having a hard time making the variables work.
Since bash doesn't support hash/maps, I'd consider perl/python to store user activity against their hash id. You also have access to vectors for variable sized activity details, eg a hash of userid's containing a vector of activities.
