      rpccp - Starts the RPC control program

      rpccp  [rpccp-command]

		Specifies one of the following control program commands:

		add element
			  Adds an element to a profile in a name service
			  entry; if the specified entry does not exist,
			  creates the entry.

		add entry Adds an entry to the name service database.

		add mapping
			  Adds or replaces server address information in the
			  local endpoint map.

		add member
			  Adds a member to a group in a name service entry;
			  if the specified entry does not exist, creates the

		exit	  Leaves the RPC control program.

		export	  Exports binding information for an interface
			  identifier, object UUIDs, or both to a server
			  entry; if the specified entry does not exist,
			  creates the entry.

		help	  Displays a list of commands or the possible
			  options of a specified command.

		import	  Imports binding information and an object UUID
			  from a server entry.

		quit	  Leaves the RPC control program.

		remove element
			  Removes selected elements from a profile.

		remove entry
			  Removes an entry from the name service database.

		remove group
			  Removes all group members and the group from the

			  specified entry.

		remove mapping
			  Removes specified elements from the local endpoint
			  map or from the endpoint map of a specified remote

		remove member
			  Removes a selected member from a group.

		remove profile
			  Removes all profile elements and the profile from
			  the specified entry.

		show entry
			  Shows the NSI attributes of an entry.

		show group
			  Shows the members of a group.

		show mapping
			  Shows the elements of the local endpoint map.

		show profile
			  Shows the elements of a profile.

		show server
			  Shows the binding information, interface
			  identifier, and object UUIDs in a server entry.

		unexport  Removes binding information, interface
			  identifiers, and object UUIDs from a server entry.

      This facility is superceded by the DCE control program (dcecp) for OSF
      DCE version 1.1.

      A server entry equates to an NSI binding attribute and, optionally, an
      object attribute; a group equates to an NSI group attribute; and a
      profile equates to an NSI profile attribute.  Typically, each server's
      entries, groups, and profiles reside in distinct name service entries.

      With the exception of the rpccp_help subcommand, this command is
      replaced at Revision 1.1 by the dcecp command.  This command may be
      fully replaced by the dcecp command in a future release of DCE, and
      may no longer be supported at that time.

      The RPC control program (RPCCP) provides a set of commands for
      managing name service use for RPC applications and for managing the
      endpoint map.

      You can use control program commands from within the control program
      or from the system prompt (represented here as a $).

      To use the control program commands from inside the control program,
      Start and enter the control program using the rpccp command alone,
      without any argument. The control program then displays the control
      program prompt (pccp>), as follows:


      You can then enter any control program command, for example:

      pccp>&gt&gt> show entry /.:/LandS/anthro/pr_server_node3

      You leave the control program and return to the system prompt using
      the exit or quit command.

      If you enter invalid input, the control program displays the valid

      To use the control program commands from the system prompt, enter the
      rpccp command with an internal command of the control program as the
      first argument.  You can do this either interactively or in a command
      procedure.  For example, you can enter the show entry command as

       rpccp show entry /.:/LandS/anthro/pr_server_node3

    Arguments and Options
      Except for the exit and quit commands, rpccp commands have one or more
      options.	Each option is identified by a - (dash) followed by a
      letter; for example, -s. Some options require arguments.

      Commands that access NSI operations also require the name of a name
      service entry as an argument.  The order of arguments and the entry-
      name option is arbitrary; for example, the following placements of
      arguments and options are equivalent:

      pccp>&gt&gt> add element	 /.:/LandS/anthro/mis_node_2  \
       -i ec1eeb60-5943-11c9-a309-08002b102989,1.0

      pccp> add element -i ec1eeb60-5943-11c9-a309-08002b102989,1.0 \

    Environmental Influences on Command Syntax
      There are variations in the action of the control program, depending
      on whether commands are entered from the system prompt or from within
      the control program.  For example, entering the annotation field of
      profile elements from the system prompt allows you to include internal
      spaces in an annotation.

	   Function	     At System Prompt	Inside Control Program
	  |Strings within  | Supported	      | Not required	       |
	  |quotation marks |		      |			       |
	  |		   |		      |			       |
	  |Wildcard	   | Supported	      | Unsupported	       |
	  |substitution	   |		      |			       |

      Note:  Some UNIX systems require that you place an escape
	     symbol (\) before string binding delimiters such as
	     brackets ([ ]) or that you place the delimiters within
	     quotation marks (' ' or '' '') at the system prompt.

      The following table describes the scope of the RPC control program

		     The dce name syntax is the only syntax currently
		     supported by the DCE Cell Directory Service (CDS).
		     However, the Name Service Interface (NSI) is
		     independent of any specific name service and, in the
		     future, may support name services that use other name
		     syntaxes.	When alternative name syntaxes are
		     supported, you can override the standard default with a
		     process-specific default by setting the
		     RPC_DEFAULT_ENTRY_SYNTAX environment variable. When
		     this variable is set for a process, the control program
		     uses it to find out the default syntax for the process.
		     You can override this default in any NSI command of the
		     control program by using the -s option to specify an
		     alternative entry syntax.	Setting
		     RPC_DEFAULT_ENTRY_SYNTAX requires specifying the
		     integer 3 to indicate the dce syntax. To set
		     RPC_DEFAULT_ENTRY_SYNTAX, use the name=value command to
		     define an environment variable.  The following command
		     specifies dce as the default name syntax in a login
		     command file:

		     # .login command file
		     # setting dce as default name syntax,

		     For the import command, you can use this environment
		     variable to indicate the entry where the search
		     operation starts.	Usually, the starting entry is a

    The Name Service Interface
      The remainder of this description contains information to help you use
      commands that call the name service interface to access name service
      entries (NSI commands).

      The DCE RPC name service interface (NSI) is independent of any
      particular name service. CDS, however, is the only name service
      available for DCE RPC Version 1.0 applications.  For more details on
      the name service interface, see the .  For a description of the DCE
      Cell Directory Service, see the .

    Name Service Entries
      To store information about RPC servers, interfaces, and objects, the
      NSI defines the following name service entries:

 Hewlett-Packard Company	    - 6 -	      OSF DCE 1.1/HP DCE 1.8

 rpccp(1m)		  Open Software Foundation		   rpccp(1m)

      server entry
		Stores binding information, interface identifiers, and
		object UUIDs for an RPC server

      group	Corresponds to one or more RPC servers that offer a common
		RPC interface, type of RPC object, or both

      profile	Defines search paths for looking in a name service database
		for a server that offers a particular RPC interface and

      Note that when the NSI is used with the Cell Directory Service, the
      name service entries are CDS object entries

    Structure of Entry Names
      Each entry in a name service database is identified by a unique global
      name made up of a cell name and a cell-relative name.

      A	 cell is a group of users, systems, and resources that share common
      DCE services. A cell configuration includes at least one cell
      directory server, one security server, and one time server.  A cell's
      size can range from one system to thousands of systems. For
      information on cells, see the CDS portion of this book.

      The following is an example of a global name:


      The parts of a global name are as follows:

      Cell name (using X.500 name syntax)
		For example:


		The symbol /... begins a cell name.  The letters before the
		equal signs (=) are abbreviations for country (C),
		organization (O), and organization unit (OU).

		For entries in the local cell, the cell name can be
		represented by a /.: prefix, in place of the actual cell
		name; for example,


		For NSI operations on entries in the local cell you can omit
		the cell name.

      Cell-relative name

		Each name service entry requires a cell-relative name, which
		contains a directory pathname and a leaf name.

		directory pathname
			  Follows the cell name and indicates the
			  hierarchical relationship of the entry to the cell

			  The directory pathname is the middle portion of
			  the global name.  The cell name is to the left of
			  the directory pathname, and the leaf name is to
			  the right, as follows:

			  cell-name + directory-pathname + leaf-name

			  The directory pathname contains the names of any
			  subdirectories in the path; each subdirectory name
			  begins with a slash (/), as follows:


			  Directory paths are created by name service
			  administrators. If an appropriate directory path
			  does not exist, ask your name service
			  administrator to extend an existing path or create
			  a new path. In a directory path, the name of a
			  subdirectory should reflect its relationship to
			  its parent directory (the directory that contains
			  the subdirectory).

		leaf name Identifies the specific entry.  The leaf name is
			  the right-hand part of global name beginning with
			  the rightmost slash.

		In the following example,  /.../C=US/O=uw/OU=MadCity is the
		cell name,  /LandS/anthro is the directory pathname, and
		/Cal_host_4 is the leaf name.


		If a name service entry is located at the cell root, the
		leaf name directly follows the cell name; for example,

 Hewlett-Packard Company	    - 8 -	      OSF DCE 1.1/HP DCE 1.8

 rpccp(1m)		  Open Software Foundation		   rpccp(1m)

      Note that when the NSI is used with CDS, the cell-relative name is a
      CDS name.

    Guidelines for Constructing Names of Name Service Entries
      A global name includes both a cell name and a cell-relative name
      composed of a directory pathname and a leaf name. The cell name is
      assigned to a cell root at its creation. When you specify only a
      cell-relative name to an NSI command, the NSI automatically expands
      the name into a global name by inserting the local cell name. When
      returning the name of a name service entry, a group member, or member
      in a profile element, NSI operations return global names.

      The directory pathname and leaf name uniquely identify a name service
      entry. The leaf name should somehow describe the entry; for example,
      by identifying its owner or its contents. The remainder of this
      section contains guidelines for choosing leaf names.  Note that
      directory pathnames and leaf names are case sensitive.

      Naming a Server Entry

		For a server entry that advertises an RPC interface or
		service offered by a server, the leaf name must distinguish
		the entry from the equivalent entries of other servers. When
		a single server instance runs on a host, you can ensure a
		unique name by combining the name of the service, interface
		(from the interface definition), or the system name for the
		server's host system.

		For example, consider two servers, one offering a calendar
		service on host JULES and one, on host VERNE.

		The server on JULES uses the following leaf name:


		The server on VERNE uses the following leaf name:


		For servers that perform tasks on or for a specific system,
		an alternative approach is to create server entries in a
		system-specific host directory within the name service
		database.  Each host directory takes the name of the host to
		which it corresponds.  Because the directory name identifies
		the system, the leaf name of the server entry name need not
		include the host name, for example:


 Hewlett-Packard Company	    - 9 -	      OSF DCE 1.1/HP DCE 1.8

 rpccp(1m)		  Open Software Foundation		   rpccp(1m)

		To construct names for the server entries used by
		distinctive server instances on a single host, you can
		construct unique server entry names by combining the
		following information: the name of the server's service,
		interface, or object; the system name of the server's host
		system, and a reusable instance identifier, such as an

		For example, the following leaf names distinguish two
		instances of a calendar service on the JULES system:



		Avoid automatically generating entry names for the server
		entries of server instances, for example, by using unique
		data such as a time stamp (calendar_verne_15OCT91_21:25:32)
		or a process identifier (calendar_jules_208004D6). When a
		server incorporates such unique data into its server entry
		names, each server instance creates a separate server entry,
		causing many server entries.  When a server instance stops
		running, it leaves an obsolete server entry that is not
		reused. The creation of a new entry whenever a server
		instance starts may impair performance.

		A server can use multiple server entries to advertise
		different combinations of interfaces and objects. For
		example, a server can create a separate server entry for a
		specific object (and the associated interfaces).  The name
		of such a server entry should correspond to a well-known
		name for the object. For example, consider a server that
		offers a horticulture bulletin board known to users as
		horticulture_bb.  The server exports the horticulture_bb
		object, binding information, and  the associated bulletin-
		board interface to a server entry whose leaf name identifies
		the object, as follows:


		Note that an RPC server that uses RPC authentication can
		choose identical names for its principal name and its server
		entry. Use of identical names permits a client that calls
		the rpc_binding_set_auth_info routine to automatically
		determine a server's principal name (the client will assume
		the principal name to be the same as the server's entry
		name). If a server uses different principal and server entry
		names, users must explicitly supply the principal name. For
		an explanation of principal names, see the DCE Security
		Service part of the DCE Application Development Guide.

      Naming a Group

		The leaf name of a group should indicate the interface,
		service, or object that determines membership in the group.
		For example, for a group whose members are selected because
		they advertise an interface named Statistics, the following
		is an effective leaf name:


		For a group whose members advertise laser-printer print
		queues as objects, the following is an effective leaf name:


      Naming a Profile

		The leaf name of a profile should indicate the profile
		users; for example, for a profile that serves the members of
		an accounting department, the following is an effective leaf


    Privilege Required
      To use the NSI commands to access entries in a CDS database, you need
      access control list (ACL) permissions.  Depending on the NSI
      operation, you need ACL permissions to the parent directory or the CDS
      object entry (the name service entry) or both.  The ACL permissions
      are as follows:

	+  To create an entry, you need insert permission to the parent

	+  To read an entry, you need read permission to the CDS object

	+  To write to an entry, you need write permission to the CDS object

	+  To delete an entry, you need delete permission either to the CDS
	   object entry or to the parent directory.

      Note that write permission does not imply read permission.

      ACL permissions for the NSI commands of the control program are
      described in the reference pages.
