Node Manager Capabilities
Configuring and Managing WebLogic Server 3-5
Node Manager Uses SSL
Communication between Node Manager and Managed Servers, Administration
Servers, or other clients requires two-way Secure Socket Layer (SSL) protocol, which
provides authentication and encryption. Node Manager uses two-way SSL to verify the
identity of Managed Servers that communicate with it. You cannot use Node Manager
features with an unsecured communication protocol.
Native Support for Node Manager
BEA provides native Node Manager libraries for Windows, Solaris, HP UX, Linux on
Intel, Linux on Z-Series, and AIX operating systems.
For other UNIX and Linux operating Systems, you must disable the
weblogic.nodemanager.nativeVersionEnabled option at the command line
when starting Node Manager to use the pure Java version. For more information. See
“Node Manager Properties” on page 4-10.
Native Node Manager is not supported on Open VMS, OS/390, AS400, UnixWare, or
Tru64 UNIX.
Node Manager Capabilities
The following sections describe Node Manager functionality.
Start Managed Servers
Client requests to start a Managed Server using Node Manager are issued to the
Administration Server for the domain that contains the Managed Server. The
Administration Server dispatches the start command to the Node Manager process on
the machine that hosts the target Managed Server. Node Manager forwards the start
request to the target Managed Server for execution. If the Managed Server does not
respond within 60 seconds, the Node Manager sets the state of the Managed Server to
