deregisterNode command

Use the deregisterNode command to unregister a node from an admin agent so that you can use the node stand-alone, register the node with another administrative agent, or federate the node with the dmgr.

Run the deregisterNode command from the bin directory of the administrative agent. The node must have been previously registered with the administrative agent. When you unregister a node, the node configuration is retained, but is marked as not registered with the admin agent.

When you run the deregisterNode command, the command stops all running application servers on the node. We can optionally stop application servers on the node that you are unregistering prior to running the deregisterNode command.

If the node that you unregister had the administrative console or management EJB applications installed prior to registering the node, they are re-enabled.

The deregisterNode command syntax is as follows:

deregisterNode [options]

Parameters

The following options are available for the deregisterNode command:

-conntype <JSR160RMI|IPC|RMI|SOAP>

The optional connector type used to connect to the administrative agent to initiate node deregistration. The default is SOAP.

Deprecated feature: You should eventually switch from the RMI connector to the JSR160RMI connector because support for the RMI connector is deprecated.depfeat

-host host_name

An optional parameter that specifies the host name of the administrative agent.

-nodepassword node_password

An optional parameter that specifies the password of the node that you are unregistering. Specify this parameter if security is on at the node and the password is different than the administrative agent password. Use this parameter with the -nodeusername parameter. The -nodeusername and -nodepassword parameters are used to stop all servers on the node.

-nodeusername node_user_name

An optional parameter that specifies the use name of the node that you are unregistering. Specify this parameter if security is on at the node and the user name is different than the administrative agent user name. Use this parameter with the -nodepassword parameter. The -nodeusername and -nodepassword parameters are used to stop all servers on the node.

-port port_number

An optional parameter that specifies the port number of the administrative agent connector port.

The default port number is 8878 for the default SOAP port of the admin agent. SOAP is the default Java Management Extensions (JMX) connector type for the command. If we have multiple product installations or multiple profiles, the SOAP port might be different than 8878. Examine the admin agent SystemOut.log file to see the current ports in use.

New feature: Beginning in WAS v8.0 you can configure the server to use the HPEL log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.New feature:

-profilePath profile_path

A required parameter that specifies the path to the profile of the base node to be unregistered.

-trace

An optional parameter that provides tracing output for the deregisterNode command.

-profileName profile_name

An optional parameter that specifies the profile name of the administrative agent.

-username username

An optional parameter that specifies the user ID of the node to be unregistered.

-password password

An optional parameter that specifies the password of the node to be unregistered.

-help

An optional parameter that prints a usage statement.

-?

An optional parameter that prints a usage statement.

Usage scenarios

The following examples demonstrate correct syntax. Commands are split on multiple lines for printing purposes.

(AIX) (Solaris)

deregisterNode.sh -conntype SOAP -port 8878
 -profilePath WAS_HOME/profiles/AppSrv01

(Windows)

deregisterNode.bat -conntype SOAP -port 8878
 -profilePath WAS_HOME\profiles\AppSrv01
