Administering GlassFish Server Nodes |
| Previous | Next | Contents |
A node represents a host on which the GlassFish Server software is installed. A node must exist for every host on which GlassFish Server instances reside. A node’s configuration contains information about the host such as the name of the host and the location where the GlassFish Server is installed on the host.
The following topics are addressed here:
Each GlassFish Server node is one of the following types of node:
DCOMA DCOM node supports communication over the Distributed Component
Object Model (DCOM) remote protocol. The DCOM remote protocol is
available only on Windows systems. If DCOM is set up and you plan to
administer your GlassFish Server instances centrally, the instances
must reside on DCOM nodes.
A DCOM node’s configuration contains the information that is
required to connect to the host through DCOM. This information
includes, for example, the user name of the Windows user and the port
number for DCOM connections to the host.
SSHAn SSH node supports communication over secure shell (SSH). If SSH
is set up and you plan to administer your GlassFish Server instances
centrally, the instances must reside on SSH nodes.
An SSH node’s configuration contains the information that is
required to connect to the host through SSH. This information
includes, for example, the user name of the SSH user and the port
number for SSH connections to the host.
CONFIGA CONFIG node does not support remote communication. If neither DCOM
nor SSH is set up and you plan to administer your instances locally,
the instances can reside on CONFIG nodes. You cannot use CONFIG
nodes for instances that you plan to administer centrally.
Each domain contains a predefined CONFIG node that is named
`localhost-`domain, where domain is the name of the domain. On the
host where the domain administration server (DAS) is running, this
node represents the local host.
DCOM NodesA DCOM node supports communication over DCOM. If DCOM is set up and
you plan to administer your GlassFish Server instances centrally, the
instances must reside on DCOM nodes. For information about setting up
DCOM, see Enabling Centralized Administration
of GlassFish Server Instances.
GlassFish Server enables you to create DCOM nodes for use by
instances, obtain information about DCOM nodes, test if DCOM nodes
are reachable, and delete DCOM nodes that are no longer required.
The following topics are addressed here:
DCOM NodeUse the create-node-dcom subcommand in remote mode to create a DCOM
node.
Before You Begin
Ensure that the Windows user can use DCOM to connect to the host that
the node will represent. By default, the create-node-dcom subcommand
validates the node’s parameters and the DCOM connection to the host. If
the Windows user cannot use DCOM to connect to the host, the validation
fails.
Note: For information about how to determine whether the Windows user can use DCOM to connect to the host, see To Test the Connection Over DCOM to a Remote Host. |
Ensure that the DAS is running.
Remote subcommands require a running server.
Run the create-node-dcom subcommand.
Specify the file that contains the alias for the Windows user’s password
through the --passwordfile option of the asadmin utility. For more
information about this file, see To Set Up
Password Authentication for the Windows User.
Note: Only the options that are required to complete this task are provided in
this step. For information about all the options for configuring the
node, see the |
C:\> asadmin --passwordfile filename create-node-dcom
--nodehost node-host [--installdir install-dir ]
node-nameThe name of the file that contains the alias for the Windows user’s password.
The name of the host that the node represents. The name of the host must be specified. Otherwise, an error occurs.
The full path to the parent of the base installation directory of the
GlassFish Server software on the host, for example, C:\glassfish3.
If the GlassFish Server software is installed in the same directory on
the node’s host and the DAS host, you can omit this option.
Your choice of name for the node that you are creating.
Example 3-1 Creating a DCOM Node
This example creates the DCOM node wpmdl1 to represent the host
wpmdl1.example.com. The GlassFish Server software is installed in the
same directory on the DAS host and on the host wpmdl1.example.com.
C:\> asadmin --passwordfile aspwalias.txt create-node-dcom
--nodehost wpmdl1.example.com wpmdl1
Command create-node-dcom executed successfully.See Also

SSH NodesAn SSH node supports communication over SSH. If SSH is set up and you
plan to administer your GlassFish Server instances centrally, the
instances must reside on SSH nodes. For information about setting up
SSH, see Enabling Centralized Administration of
GlassFish Server Instances.
Note: Windows systems also support communications over DCOM as an alternative to SSH. |
GlassFish Server enables you to create SSH nodes for use by instances,
obtain information about SSH nodes, test if SSH nodes are reachable,
and delete SSH nodes that are no longer required.
The following topics are addressed here:
SSH NodeUse the create-node-ssh subcommand in remote mode to create an SSH
node.
Before You Begin
Ensure that the SSH user can use SSH to log in to the host that the node
will represent. By default, the create-node-ssh subcommand validates
the node’s parameters and the SSH connection to the host. If the SSH
user cannot use SSH to log in to the host, the validation fails.
Ensure that the DAS is running.
Remote subcommands require a running server.
Run the create-node-ssh subcommand.
Note: Only the options that are required to complete this task are provided in
this step. For information about all the options for configuring the
node, see the If you are using password authentication for the SSH user, you must
specify a password file through the |
asadmin> create-node-ssh --nodehost node-host [--installdir install-dir ]
node-nameThe name of the host that the node represents. The name of the host must be specified. Otherwise, an error occurs.
The full path to the parent of the base installation directory of the
GlassFish Server software on the host, for example,
/export/glassfish3/. If the GlassFish Server software is installed
in the same directory on the node’s host and the DAS host, you can
omit this option.
Your choice of name for the node that you are creating.
Example 3-6 Creating an SSH Node
This example creates the SSH node sj01 to represent the host
sj01.example.com. The GlassFish Server software is installed in the
same directory on the DAS host and on the host sj01.example.com.
asadmin> create-node-ssh --nodehost sj01.example.com sj01
Command create-node-ssh executed successfully.Troubleshooting
The create-node-ssh subcommand might fail to create the node and
report the error Illegal sftp packet len. If this error occurs, ensure
that no the startup file on the remote host displays text for
noninteractive shells. Examples of startup files are .bashrc,
.cshrc, .login, and .profile.
The SSH session interprets any text message that is displayed during login as a file-transfer protocol packet. Therefore, any statement in a startup file that displays text messages corrupts the SSH session, causing this error.
