Shell script for running JCL jobs on the mainframe via ftp

runZosJcl.sh script is intended to execute job from z/OS dataset via ftp

Also, this Shell script template can be used as part of the Jenkins pipeline to automate the launch of JCL jobs.

Link to shell script sources (runZosJcl.sh)

Instructions:

Execution format::

>./runZosJcl.sh [job] [output_file]

• job - fully-qualified job name in quotation marks
• output_file - file where job output log will be saved

Script returns 1 if dataset with JCL was not found or job failed (completed with error or RC>04)

Example:

>./runZosJcl.sh 'USER01.TESTPROG.JCL(TEST)' build_output.txt

runZosJcl.sh

#!/bin/sh
HOST=#Mainframe IP-address here#
USERID=#MF User#
USERPSW=#User password#

echo reading input parameters
INPUTJOB=$1
OUTPUT=$2
echo JCL: $INPUTJOB
echo Output file: $OUTPUT

TMPFILE=tmp.txt

echo run JCL from z/OS
echo "
