ACE自适配通信环境（ADAPTIVE Communication Environment）是可以自由使用、开放源码的面向对象（OO）框架（Framework）

This file describes the usage of the Dump-Restore utility for the ACE
Name Server.

Similar to the test application provided in the ../Client/ directory,
a simple ASCII menu-driven interface is provided to the user:

         Name Service Main Menu
         ----------------------
  *** Using Process Local Database ***
 
** No Input File Specified **
<P> Use Process Local Database
<N> Use Node Local Database
<H> Set Remote Name server <host> and <port>
<F> Set Input File <file name>
 
<B> Bind
<U> Unbind
<R> Rebind
<D> Dump <file name>
<Q> or ^C (exit) 

Initially, the user can select the type of database from the menu:

<P> uses the process local database (i.e., the
    database is called the same name as the process
    and stored in /tmp).
<N> uses the node local database (which defaults
    to /tmp/localnames).
<H> uses the net local database by specifying host and port
    number (by default this is stored in a file called
    /tmp/globalnames on the server). 
<F> Sets the name of the input file that will be used by the
    test application to populate the database.  The format of
    the file should be:

    	name=<name1>
	value=<value1>
	type=[<type1>]
	name=<name2>
	value=<value2>
	type=[<type2>]
	.
	.
	.
	
    Note that the type field is optional. However, if no type
    information is associated with a name binding, a null entry still
    needs to be present (i.e., type=).

Once the input file has been specified, the user can then do one of
the following:

<B> Bind             -- bind all the bindings in the file to the database.
                        This can be used to "restore" the state of the
                        Name Server.
<U> Unbind           -- unbind all the bindings in the file from the database.
<R> Rebind           -- rebind all the bindings in the file to the database.
<D> Dump <file name> -- dump the state of the database to <filename>.
<Q> or ^C (exit)     -- exit gracefully, saving the contents of the
                        Name Server in persistent shared memory.
 
Note that the dump file is stored in ASCII with exactly the same
format as the input file.  Also, one can easily change the test
application so that a call to Dump results in the state of the
database dumped to standard output instead of a file.
