Configuring Node Manager
Configuring and Managing WebLogic Server 4-5
Configure a Machine to Use Node Manager
If Node Manager must accept commands from remote clients, you must create a
machine definition for each machine that runs a Node Manager process.
A machine definition associates a particular machine with the server instances it hosts,
and specifies the connection attributes for the Node Manager process on that machine.
You can create a machine definition using the Machine-->Configuration-->Node
Manager tab in the Administration Console. Enter the DNS name or IP address upon
which Node Manager listens in the Listen Address box. If you identify the Listen
Address by IP address (except for the localhost address, 127.0.0.1), you must disable
Host Name Verification on remote Administration Servers, or other clients such as
weblogic.Admin, that will access Node Manager.
Note: If host name verification is disabled, and you specify the Listen Address of
the Administration Server by its IP address, you must still include that IP
address in
nodemanager.hosts.
For more information on disabling host name verification, see “Using a Hostname
Verifier” in Managing WebLogic Security. For instructions on configuring a machine,
see “Configuring a Machine” in Administration Console Online Help.
Configure Managed Server Startup Arguments
Specify the startup arguments that Node Manager will use to start a Managed Server
in the Server—>Configuration—>Remote Start tab for the Managed Server. If you do
not specify startup arguments for a Managed Server in this fashion, Node Manager
uses its own properties as defaults to start the Managed Server. Although these defaults
are sufficient to boot a Managed Server, to ensure a consistent and reliable boot
process, configure startup arguments for each Managed Server. For instructions, see
“Configure Startup Arguments for Managed Servers” in Administration Console
Online Help.
Ensure Administration Server Address is Defined
Make sure that a Listen Address is defined for each Administration Server that will
connect to the Node Manager process. If the Listen Address for a Administration
Server is not defined, when Node Manager starts a Managed Server it will direct the
target server to contact localhost for its configuration information.
