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.
