Description

    Note –

    This command is available only in domains that are configured to support clusters, such as domains that are created with the cluster profile or the enterprise profile. For information about profiles, see Usage Profiles in Sun Java System Application Server 9.1 Administration Guide.

    The node agent facilitates remote server instance management. It is the responsibility of the node agent to create, start, stop, and delete a server instance. Every node agent must have a unique name and every new server instance must be created with a reference to a node agent name defining the machine on which the instance will reside. A node agent must be present on every machine that hosts server instances, including the machine hosting the Domain Administration Server (DAS).

    The DAS connection options (host, port, user) identify the agent's initial target domain. The DAS does not need to be running when the node agent is being created. When the node agent is started, the agent attempts to contact the DAS to join the domain.

Options

    -t --terse

    Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.

    -e --echo

    Setting to true will echo the command line statement on the standard output. Default is false.

    -I --interactive

    If set to true (default), only the required password options are prompted.

    -H --host

    The machine name where the domain administration server is running. The default value is localhost.

    -p --port

    The HTTP/S port for administration. This is the port to which you should point your browser in order to manage the domain. For example, http://localhost:4848.

    The default port number is 4848.

    -s --secure

    If set to true, uses SSL/TLS to communicate with the domain administration server.

    -u --user

    The authorized domain administration server administrative username.

    If you have authenticated to a domain using the asadmin login command, then you need not specify the --user option on subsequent operations to this particular domain.

    --passwordfile

    The --passwordfile option specifies the name, including the full path, of a file containing the password entries in a specific format. The entry for the password must have the AS_ADMIN_ prefix followed by the password name in uppercase letters.

    For example, to specify the domain administration server password, use an entry with the following format: AS_ADMIN_PASSWORD=password, where password is the actual administrator password. Other passwords that can be specified include AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, and AS_ADMIN_ALIASPASSWORD.

    All remote commands must specify the admin password to authenticate to the domain administration server, either through --passwordfile or asadmin login, or interactively on the command prompt. The asadmin login command can be used only to specify the admin password. For other passwords, that must be specified for remote commands, use the --passwordfile or enter them at the command prompt.

    If you have authenticated to a domain using the asadmin login command, then you need not specify the admin password through the --passwordfile option on subsequent operations to this particular domain. However, this is applicable only to AS_ADMIN_PASSWORD option. You will still need to provide the other passwords, for example, AS_ADMIN_USERPASSWORD, as and when required by individual commands, such as update-file-user.

    For security reasons, passwords specified as an environment variable will not be read by asadmin.

    The default value for AS_ADMIN_MASTERPASSWORD is changeit.

    --help

    Displays the help text for the command.

    --agentdir

    Like a Domain Administration Server (DAS), each node agent resides in a top level directory named agentdir/nodeagent_name. If specified, the path must be accessible in the filesystem. If not specified, the node agent is created in the default install_dir/nodeagents directory.

    --agentport

    The port on which the node agent's JMX connector listens and accepts requests. If not specified, then a random unused port is chosen.

    --agentproperties

    The following agent properties are available:

    listenaddress

    The address used by the JMX connector to listen for requests or notifications. The default is 0.0.0.0.

    remoteclientaddress

    The address used by DAS to connect to the Node Agent. The default is the hostname of the server.

    loglevel

    The initial log level at which messages are logged. The default is INFO.

    --savemasterpassword

    Setting this option to true allows the masterpassword to be written to the file system. This is necessary so that the start-domain command can start the server without having to prompt the user. However, for security purposes, the default setting is false because saving the master password on the disk is an insecure practice.

Operands

    nodeagent_name

    The name of the node agent must be unique in the domain. If not specified, the nodeagent_name defaults to the machine's host name. Do not use any reserved words or characters in the node agent name. For more information on these restrictions, see the asadmin help page (enter asadmin --help at the command prompt).

Examples

    Example 1 Using create-node-agent


    asadmin>create-node-agent --host host1 --port 4848
--user admin1 --passwordfile password.txt nodeagent1
Node Agent nodeagent1 created.

    The node agent nodeagent1 was created in the default install_dir/nodeagents directory.
