64 DB2 Deployment Guide
2.3.3 Creating the deployment script
The SSH and NFS should be configured prior to implementing the DB2 server
deployment. These are basis for running an automatic deployment across the
network without any user interaction. Our deployment script performs the
following tasks:
Parse the command line options and perform basic syntax checking.
Go through the hosts one by one and perform installation in sequence. The
host names are read in from the command line.
For each target host, mount the DB2 server installation image to the local file
system using NFS. If the mount fails, this machine will be skipped.
For response file based deployment, the response file should be placed on a
NFS directory for others to access.
After installation is finished on one machine, unmount NFS and move on to
the next target host.
If we encounter any error, the script will try forwarding a message to the standard
output. In addition, an installation log file is generated on each installation target
by db2setup or db2_install (for Linux and UNIX).
Figure 2-7 depicts the process.
