Chapter 2. DB2 server deployment 79
is located. The temporary path for the fix pack image is /tmp/v95fp1/ese as
shown in Figure2-8. It is exported to every other machine using NFS.

Just as for with mass server deployment, you have to ensure that SSH and NFS
are installed. For steps to configure SSH and NFS, refer to 2.3.1, “Setup of SSH
and NFS” on page 59.

Script logic and command line options

The fix pack deployment script is similar to the DB2 server deployment script.
The major difference is that we have to check and stop the DB2 processes
associated with the DB2 copy to be updated. Our fix pack deployment script
performs the following tasks:
򐂰Parse the command line options.
򐂰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.
򐂰Check if any DB2 instance processes still exist. If not, then start the fix pack
deployment.
