Installing feature packs silently on a WebSphere Commence clustered environment

To install the WebSphere Commerce feature pack, your system must meet the following prerequisites:

• Log on:
  • As a root user
  • Or as a non-root user that owns WC_installdir
• If you want log on as a non-root user, ensure that the non-root user owns the appropriate .profile file and consider the following installation limitations.
  • Feature packs that are installed by a non-root user cannot be registered through native operating system mechanisms, such as the Red Hat Package Manager (RPM) on Linux. WebSphere software registers in the installation registry file and the vpd.properties file. All installed components are fully functional despite the lack of native registration.
  • Feature packs installed by the root user must be uninstalled by the root user only.
  If you accept the limitations, to change ownership, perform the following steps:
  1. Log on as the root user.
  2. If the directory /tmp/niflog/ exists, create a backup and then remove the directory.
  3. Change the ownership of /home/non-root_userdir/.profile to non-root user and the non-root user group. For example, change ownership of /home/wasuser/.profile to wasuser and wasgroup.
  4. Set the non-root user's umask to 0027.
• Log on with a user profile that has *SECOFR authority.
• Log on to a user that has Windows Administrative user rights.
