Root and non-root installation
On UNIX Network Manager can be installed as either the root user or a non-root user.
If you have installed any other IBM® Tivoli® products into the same installation directory, you must install Network Manager as the same user that installed the other products.
The Network Manager web applications must always be run as the user who installed the product.
After installation, you can configure the Network Manager core components to be run as a different user. For example, if you installed as the root user, you can configure the core components to be run as a non-root user.
Restriction: When Network Manager is installed and run as root,
scripts are installed that restart Network Manager and Tivoli Netcool/OMNIbus processes when the
server is rebooted. When Network Manager is installed and run as a non-root user, Network Manager
and Tivoli Netcool/OMNIbus processes
are not restarted automatically when the server is rebooted. However, as a post-installation task
for non-root installations, you can configure the processes to start automatically when your system
is rebooted, as described in Configuring processes to start automatically in a non-root installation.
Restriction: IBM Tivoli Business Service Manager must
run as non-root. When installing Network Manager and IBM Tivoli Business Service Manager on
the same server, make sure you install and run both as a non-root
user.
