Installation guide

1-20 BEA Products Installation Guide
Note: You are prompted to install Node Manager as a Windows service only during an initial
installation. If you install additional product components during a subsequent
installation, you are not prompted to install Node Manager as a Windows service.
To install Node Manager as a Windows service in silent mode, you need to specify the
appropriate values in the
silent.xml file. For more information, see “Creating a silent.xml File
for Silent-Mode Installation” on page 5-3.
You can also install and uninstall Node Manager as a Windows service using the following
scripts that are provided when you install WebLogic Server:
z WL_HOME\server\bin\installNodeMgrSvc.cmd
z WL_HOME\server\bin\uninstallNodeMgrSvc.cmd
In these pathnames, WL_HOME is the product installation directory in which you installed
WebLogic Server, typically
C:\bea\weblogic92.
Note: To perform Server migration and other tasks, the user ID that execute scripts such as
wlscontrol.sh must have enough sufficient security permissions. This includes being
able to bring an IP address online or take an IP address offline via a network interface.
The commands required to perform server migration are
ifconfig and arping. Since
these scripts require elevated OS privileges, it is important to note that this can prevent a
potential security vulnerability.
Additional Considerations for Node Manager Installation
z When you install Node Manager as a Windows service, it is registered with the product
installation directory in which you are installing the software, for example,
C:\bea\weblogic92. Node Manager can be used to manage communication with all
domains associated with that installation directory.
If you install additional instances of WebLogic Server 9.2 on a machine, in different BEA
Home directories, you can install a Node Manager instance as a Windows service for each
installation. Each Node Manager instance will manage the domains associated with the
relevant installation.
z When you install Node Manager as a Windows service during the installation process, the
Node Manager listen port is specified in the BEA registry file,
registry.xml, located in
the BEA Home directory associated with the installation, typically
c:\bea.
Note: Do not edit this file manually. Doing so may cause operating problems for the
currently installed BEA products, or result in installation problems when future BEA
products or maintenance upgrades are installed. Changing the Node Manager listen
port value in the
registry.xml does not change the port for the installed service.
