This section provides instructions for starting and terminating the SYSRPC utility and describes the main features and functions provided by the utility.
To invoke the SYSRPC utility
From the library workspace in the Natural Studio tree view, select a library.
From the Tools menu, choose Configuration Tools and Remote Procedure Call.
Or:
In the Command line, enter the following command:
SYSRPC
The SYSRPC - Remote Procedure Call window appears and displays the service directory tree view for the library specified. This is indicated in the name of the directory root node: Service Directory [library-name].
When you invoke SYSRPC for the first time for a library, as shown in the example below, the tree view contains example (dummy) data. The name of the service directory root node is Example Service Directory which will change to Service Directory [library-name] when you use the Save or Save As function (see Menu Bar below), regardless of any tree view modifications. For a list of possible root names, see Root Node Names in the section Service Directory Maintenance.
The menus and toolbar buttons in the SYSRPC - Remote Procedure Call window provide all functions required to maintain a service directory, generate interface objects and execute server commands.
To terminate the SYSRPC utility
In the SYSRPC - Remote Procedure Call window, from the Object menu, choose Exit.
Or:
Choose ALT+F4.
Or:
Choose the standard Windows close function.
If a window appears with a message saying that subprogram NATCLTGS is missing (needed at runtime), choose Yes to confirm the generation of NATCLTGS, or choose No to cancel the operation.
The tree view in the SYSRPC - Remote Procedure Call window displays all items (tree nodes) required for service directory maintenance. For explanations of the tree nodes, see Tree Nodes in Service Directory Maintenance. For explanations of the tree node hierarchy, see Service Directory Concept in Service Directory Maintenance.
Do not confuse a tree node of the service directory with the node to which an RPC connection is established (see Natural RPC Terminology in the Natural Remote Procedure Call documentation).
You can manipulate the tree nodes by using the functions provided with the menu bar, the toolbar and the context menu described below.
You can expand or collapse tree nodes by choosing the toggle
(expand) or the toggle
(collapse) in front of a tree node. Alternatively, you can choose the
ARROW keys. Double-click on an expandable tree node to display all
subordinate items.
To expand all nodes of a tree
In the SYSRPC - Remote Procedure Call window, select the root node and choose Expand Tree from the context menu.
Or:
Choose CTRL+F12.
The menus, menu items and equivalent shortcut keys (if available) provided to execute SYSRPC functions are described in the following section.
