The installation instructions in the WebSphere®
Application Server Information Centers all contain a statement similar to
the following:
"Install this product as root on a Linux® or UNIX-based operating system,
or from a user ID that is part of the Administrator group on a Windows
platform. If you create a CD-ROM copy of the product CD-ROM, create it as
root."
The same statement applies to the installation of fix packs, interim
fixes and cumulative fixes to WebSphere Application Server after the
initial installation is performed. The same level of authority is also
required to perform a migration from one version of WebSphere to
another.
Systems where the user has been changed to a non-root ID, sudo-root or
a non-administrative ID for daily operation must change the user, along
with file ownership, back to comply with the above statement before
installing fix packs, interim fixes or cumulative fixes to WebSphere.
Alternatively, you can install WebSphere full installation, fix packs,
interim fixes or cumulative fix packs as root or administrator user first
before switching to a non-root user.
