NFS configuration

In a mass deployment scenario, copying the installation image to each target machine is not a convenient method. It is time consuming and requires extra temporary space to be allocated on each machine to keep the image.

A better approach is to keep the installation image in a file server and make it available to other systems. We keep the installation image on Zaire and make the image available to others through Network File System (NFS).

The steps required to set up the NFS share on Zaire are as follows:

1.Install NFS software if it is not found on your system. Then start the NFS server. You can use smit or smitty to start the NFS daemon:

smitty nfsconfigure

2.Add the installation image path to the NFS exports list. The default mode of the exported directory is read-write. As we do not change the installation image from the deployed machine, the mode can be changed to read-only. The following command adds a directory to the Exports list:

smitty mknfsexp

3.Verify that the desired path has been exported correctly. In Example 2-17,we extract the installation image of DB2 Enterprise Server Edition into the path / tmp/v95ga/ese for everyone to access.

Example 2-17 Verify NFS configuration from command line

#showmount -e zaire

export list for zaire: /tmp/v95ga/ese (everyone)

After finishing the SSH and NFS configuration, we are now ready for the mass deployment.

2.3.2 DB2 license

DB2 server products require appropriate licenses based on the features and products you are deploying. DB2 provides a method for automatically installing licenses during the deployment process. This involves copying the license files to the db2/license directory from the install image. When a given DB2 server product image is deployed, DB2 automatically installs the licenses present in the db2/license directory.
