jcl_assess v0.1

INTRODUCTION

This tool assesses JCLs. Since it also includes the custom cobol parser, the COBOL files will be also analyzed throughout the JCLs.

Getting started

Prerequisites

1. Perl 5

• Unix-like operating system

Type the following command for the manual installation:

$ yum -y install perl # CentOS/RHEL

$ sudo apt-get install perl # Ubuntu

Downloading jcl_assess

Clone jcl_assess onto your local machine.

$ git clone https://github.com/ykhwong/jcl_assess.git

Configuration

dir.lst

Go to the config directory and open the dir.lst. Specify the directory path for below.

Parameter	Description	Example	-
PATH=	Main path to the source files	PATH=/src_path	Required
BIND=	Path to the BIND files	BIND=bind	Required
COPY=	Path to the COPY files	COPY=copy	Required
INCLUDE=	Path to the INCLUDE files	INCLUDE=include	Required
JCL=	Path to the JCL files	JCL=jcl	Required
PARM=	Path to the PARM	PARM=parm	Required
PROC=	Path to the PROC	PROC=proc	Required
COBOL=	Path to the COBOL	COBOL=cobol	Required
CICS=	Path to the CICS	CICS=cics	Optional
BMS=	Path to the BMS	BMS=bms	Optional

For example, if the PATH is set to /src_path and BIND is set to bind, the BIND directory that jcl_assess searches will become /src_path/bind.

Other lst files

Open the following files and add the target filenames that you are going to assess.

File	-	Note
bms.lst	Optional
cics.lst	Optional
input.lst	Optional
jcl.lst	Required
util.lst	Required	Any mainframe-specific utilities can be added here

Place all JCLs and COBOLs into the directories

Copy all JCLs and COBOLs into the directories that you specified in the configuration file.

For example, if the PATH is set to /src_path and JCL is set to jcl in the dir.lst, then all JCL files must be copied to the /src_path/jcl directory.

Assessment

After everything is set up correctly, you can start the assessment by running the following command.

$ sh jcl_assess.sh

The shell script will call the jcl_assess.pl which also may call the cobol_parser.pl given that the COBOL files are provided. All the results will be saved to the ./result directory.

Create a call-tree graph

In order to create a call-tree graph based on the result, please run the following script file.

$ sh show_result.sh
