Description

The create-node-dcom subcommand creates a node that is enabled for communication over the Distributed Component Object Model (DCOM) remote protocol. The DCOM protocol is available only on Windows systems.

A node represents a host on which the \{product---name} software is installed. A node must exist for every host on which \{product---name} instances reside.

In a DCOM-enabled network, the domain administration server (DAS) contacts a node’s host through the DCOM connector to manage \{product---name} instances that reside on the node. DCOM is used only for communications between hosts. DCOM is never used for communications within a single host.

By default, the subcommand fails and the node is not created if the DAS cannot contact the node’s host through DCOM. To force the node to be created in the DAS configuration even if the host cannot be contacted through DCOM, set the --force option to true.

The create-node-dcom subcommand cannot create a node that represents the local host, that is, the host on which the subcommand is run. The subcommand fails regardless of how the local host is specified, for example, by using the keyword localhost, the Internet Protocol (IP) address of the host, or the host name.

This subcommand is supported in remote mode only.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin(1M) help page.

--help

-?

Displays the help text for the subcommand.

--nodehost

The name of the host that the node represents. The name of the host must be specified. Otherwise, an error occurs.

--installdir

The full path to the parent of the base installation directory of the \{product---name} software on the host, for example, C:\glassfish3. The default is the parent of the default base installation directory of the \{product---name} software for the DAS. This default is useful only if \{product---name} is installed in the same location on all hosts.

--nodedir

The path to the directory that is to contain \{product---name} instances that are created on the node. The default is as-install`\nodes`, where as-install is the base installation directory of the \{product---name} software on the host. If a relative path is specified, the path is relative to the as-install directory.

--windowsuser

-w

The user on this node’s host that is to run the process for connecting to the host through DCOM. The default is the user that is running the DAS process. If the --nodehost option is set to localhost-`domain, the `--windowsuser option is ignored

--windowsdomain

-d

The name of the Windows domain that contains the user that the --windowsuser option specifies. The default is the name of the host on which the subcommand is run.

--force

Specifies whether the node is created in the DAS configuration even if validation of the node’s parameters fails. To validate a node’s parameters, the DAS must be able to contact the node’s host through DCOM. Possible values are as follows:

false: The node is not created if validation of the node’s parameters fails (default).
true: The node is created even if validation of the node’s parameters fails.

--install

Specifies whether the subcommand shall install the \{product---name} software on the host that the node represents.
Possible values are as follows:

false: The subcommand shall not install the \{product---name} software on the host (default).
true: The subcommand shall install the \{product---name} software on the host.

--archive

The absolute path to the archive file of the \{product---name} software that is to be installed. If this option is omitted and the --install is true, the subcommand creates a ZIP archive of the \{product---name} software from the installation where this subcommand is run. The archive does not contain the domains directory or the nodes directory.

Operands

node-name

The name of the node.
The name must meet the following requirements:

The name may contain only ASCII characters.
The name must start with a letter, a number, or an underscore.
The name may contain only the following characters:
- Lowercase letters
- Uppercase letters
- Numbers
- Hyphen
- Period
- Underscore
The name must be unique in the domain and must not be the name of another node, a cluster, a named configuration, or a \{product---name} instance.
The name must not be domain, server, or any other keyword that is reserved by \{product---name}.

Examples

Example 1 Creating a Node

This example creates the node wpmdl1 for the host wpmdl1.example.com. By default, the parent of the base installation directory of the \{product---name} software is C:\glassfish3.

asadmin> create-node-dcom
--nodehost wpmdl1.example.com wpmdl1
Command create-node-dcom executed successfully.

Example 2 Creating a Node With a Specific Installation Directory

This example creates the node wyml1 for the host wyml1.example.com. The parent of the base installation directory of the \{product---name} software on this host is C:\middleware\glassfish3.

asadmin> create-node-dcom --installdir C:\middleware\glassfish3
--nodehost wyml1.example.com wyml1
Command create-node-dcom executed successfully.

Example 3 Forcing the Creation of a Node

This example forces the creation of node xkyd for the host xkyd.example.com. The node is created despite the failure of the DAS to contact the host xkyd.example.com to validate the node’s parameters.

asadmin> create-node-dcom --force --nodehost xkyd.example.com xkyd
Warning: some parameters appear to be invalid.
com.sun.enterprise.universal.process.WindowsException: Connection in error
Continuing with node creation due to use of --force.
Command create-node-dcom executed successfully.

Exit Status

0: command executed successfully
1: error in executing the command
