Chapter 4. Deploying applications with DB2 165

4. The purpose of the script app_install is to copy an application file and extract

CLI driver files to the specified path, and to perform application environment

configurations after the deployment. Example 4-12 shows the script code.

The script app_install has two command line options:

– The option -p specifies the path on the target machine indicating where

the application is to be deployed.

– The option -r indicates that we want the script to configure the system

variables for us. Do not use this option if you want the configuration to be

done manually.

Example 4-12 Source codes of script app_install
