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. Example4-12 shows the script code.
The script app_install has two command line options:
– The option -p spec ifies 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.
