IceGrid provides two administrative clients: a command-line tool and a graphical application.

On this page:

IceGrid Command Line Utility

The icegridadmin utility is a command-line tool for administering an IceGrid domain. Deploying an application with this utility requires an XML file that defines the descriptors.

Usage

The IceGrid administration tool supports the following command-line options:

{zcode}
Usage: icegridadmin [options]
Options:
-h, --help           Show this message.
-v, --version        Display the Ice version.
-e COMMANDS          Execute COMMANDS.
-d, --debug          Print debug messages.
-s, --server         Start icegridadmin as a server (to parse XML
                     files).
-u, --username       Login with the given username.
-p, --password       Login with the given password.
-S, --ssl            Authenticate through SSL.
-r, --replica NAME   Connect to the replica NAME.
{zcode}

The -e option causes the tool to execute the given commands and then exit without entering an interactive mode. The -s option starts icegridadmin in a server mode that supports the IceGrid::FileParser interface; a proxy for the object is printed to standard output. If neither -e nor -s is specified, the tool enters an interactive mode in which you issue commands at a prompt.

To communicate with the IceGrid registry, icegridadmin establishes an administrative session. The tool uses SSL authentication if you specify the -S option or define its equivalent property IceGridAdmin.AuthenticateUsingSSL. Otherwise, icegridadmin uses password authentication and prompts you for the username and password if you do not specify them via command-line options or properties. If you want icegridadmin to establish its session using a Glacier2 router, define Ice.Default.Router appropriately. See IceGrid Administrative Client Properties for more information on the tool's configuration properties.

Once the session is successfully established, icegridadmin displays its command prompt. The help command displays the following usage information:

• help
  Print this message.

• exit, quit
  Exit this program.

• CATEGORY help
  Print the help section of the given CATEGORY

• COMMAND help
  Print the help of the given COMMAND.

The tool's commands are organized by category. The supported command categories are shown below:

• application
• node
• registry
• server
• service
• adapter
• object
• server template
• service template

You can obtain more information about each category using the help command:

{zcode}
>>> application help
{zcode}

Application Commands

• application add [-n | --no-patch] DESC [TARGET ... ] [NAME=VALUE ... ]

  Remove the application named NAME.

• application describe NAME
  Describe the application named NAME.

  Print the number of processor sockets for node NAME. If NAME is omitted, print the number of processor sockets for each node. (The IceGrid.Node.ProcessorSocketCount property allows you to explicitly set this value for systems where the number of sockets cannot be obtained programatically.)

• node show [OPTIONS] NAME [stderr | stdout]
  Print the text from the node's standard error or standard output. The supported options are shown below:
  • -f, --follow
    Wait for new text to be available.

  Print the text from the registry's standard error or standard output. The supported options are shown below:
  • -f, --follow
    Wait for new text to be available.
  • -t, --tail N
    Print the last N lines of text.
  • -h, --head N
    Print the first N lines of text.

Configuration

icegridadmin requires that the locator proxy be defined in the configuration property Ice.Default.Locator. If a configuration file already exists that defines this property, you can start icegridadmin using the configuration file as shown below:

{zcode}
$ icegridadmin --Ice.Config=<file>
{zcode}

Otherwise, you can define the property on the command line:

{zcode}
$ icegridadmin --Ice.Default.Locator=<proxy>
{zcode}

Refer to the discussion of our ripper client for more information on configuring the Ice.Default.Locator property for an IceGrid client.

IceGrid Graphical Client

The graphical administration tool, IceGrid Admin, allows you to perform anything that you can do from the command line via a GUI. Please refer to the instructions included with your Ice distribution for details on how to start the administration tool.
