NAME
servertool - The Java(TM) IDL Server Tool
servertool provides an ease-of-use interface for application programmers to register, unregister,
startup and shutdown a server.
SYNOPSIS
servertool -ORBInitialPort nameServerPort [ options ]
The command-line tool displays with a servertool > prompt. Enter commands at the servertool > prompt.
The -ORBInitialPort nameServerPort option is required. The value for nameServerPort must specify the
port on which orbd is running and listening for incoming requests. You must become root to start a
process on a port under 1024. For this reason, we recommend that you use a port number greater than
or equal to 1024 for the nameServerPort.
DESCRIPTION
The servertool provides the command-line interface for the application programmers to register,
unregister, startup, and shutdown a server. Other commands are provided to obtain various statisti-cal statistical
cal information about the server.
OPTIONS
-ORBInitialHost nameServerHost
Specifies the host machine on which the name server is running and listening for incoming
requests. The nameServerHost defaults to localhost if this option is not specified. If orbd
and servertool are running on different machines, you must specify the name or IP address of
the host on which orbd is running.
-Joption
Pass option to the Java virtual machine, where option is one of the options described on the
reference page for the java application launcher. For example, -J-Xms48m sets the startup
memory to 48 megabytes. It is a common convention for -J to pass options to the underlying
virtual machine.
COMMANDS
register
-server serverClassName -classpath classpathToServer [ -applicationName alternateServerName
-args argsToServer -vmargs flagsToBePassedToJavaVM ]
Register a new server with the Object Request Broker Daemon (ORBD). If the server is not
already registered, it is registered and activated. This command causes an install method to
be invoked in the main class of the server identified by the -server option. The install
method must be public static void install(org.omg.CORBA.ORB). The install method is optional
and enables the developer to provide their own server installation behavior (for example, cre-ating creating
ating database schema).
unregister
-serverid serverId | -applicationName name
Unregister a server from the ORBD by using either its server id or its application name. This
command causes an uninstall method to be invoked in the main class of the server identified by
the -server option. The uninstall method must be public static void unin-stall(org.omg.CORBA.ORB). uninstall(org.omg.CORBA.ORB).
stall(org.omg.CORBA.ORB). The uninstall method is optional and enables the developer to pro-vide provide
vide their own server uninstall behavior (for example, undoing the behavior of the install
method).
getserverid
-applicationName applicationName
Return the server id that corresponds with an application.
list
List all information about all persistent servers registered with the ORBD.
listappnames
List the application names for all server currently registered with the ORBD.
listactive
List all information about all persistent servers that have been launched by the ORBD and are
currently running.
locate
-serverid serverId | -applicationName applicationName [ -endpointType endpointType ]
Locate the endpoints (ports) of a specific type for all ORBs created by a registered server.
If a server is not already running, it is activated. If an endpoint type is not specified,
then the plain/non-protected endpoint associated with each ORB in a server is returned.
locateperorb
-serverid serverId | -applicationName applicationName [ -orbid ORB_name ]
Locate all the endpoints (ports) registered by a specific ORB of registered server. If a
server is not already running, then it is activated. If an orbid is not specified, the default
value of "" is assigned to the orbid. If any ORBs are created with an orbid of empty string,
all ports registered by it are returned.
orblist
-serverid serverId | -applicationName applicationName ]
Lists the ORBId of the ORBs defined on a server. An ORBId is the string name for the ORB cre-ated created
ated by the server. If the server is not already running, it is activated.
shutdown
-serverid serverId | -applicationName applicationName ]
Shutdown an active server that is registered with ORBD. During execution of this command,
the shutdown() method defined in the the class specified by either the -serverid or -applica-tionName -applicationName
tionName parameter is also invoked to shutdown the server process appropriately.
startup
-serverid serverId | -applicationName applicationName
Startup or activate a server that is registered with ORBD. If the server is not running, this
command launches the server. If the server is already running, an error message is returned to
the user.
help
List all the commands available to the server through the server tool.
quit
Exit the server tool.
