Abstract

The Retrieve Configuration Source (RTVCFGSRC) command provides the user with the ability to build source file members containing commands for creating configuration object (line, controller, device, mode, and class-of-service) descriptions. RTVCFGSRC builds the commands from object descriptions which already exist in a system. These statements, therefore, provide a way to re-create existing configuration object descriptions.

Retrieve Configuration Source

The Retrieve Configuration Source (RTVCFGSRC) command provides the user with the ability to build source file members containing commands for creating configuration object (line, controller, device, mode, and class-of-service) descriptions. RTVCFGSRC builds the commands from object descriptions which already exist in a system. These statements, therefore, provide a way to re- create existing configuration object descriptions.

A configuration object description is created on a system by a control language program or interactively. The manner in which the object was created has no effect on the output produced by RTVCFGSRC since RTVCFGSRC produces command source by examining the object description used by the system. A program is then created from the output of RTVCFGSRC which re- creates the object descriptions. The figure illustrates the function of RTVCFGSRC.

The following steps describe how the RTVCFGSRC command works. They are done in the order shown to minimize the problems associated with attaching devices to controllers, controllers to lines, twinaxial data link control (TDLC) lines to workstation controllers, and so on. This order also enables commands to be built which can reproduce an entire network of configuration object descriptions.

1. Lists are created for all configuration objects which match the names and object type specified by the user. These lists contain object-specific information such as pointers to the objects.

2. For each non-TDLC line in the list of lines: a. A create line command string is built containing the parameter names and values associated with the line description. Attachment information (the attached, non-switched controller and switched controller list) may or may not be included depending upon the retrieval type specified by the user. b. For a network retrieval, the names of the attached non-switched controllers are added to the list of controllers to be retrieved. c. The command string is processed and is written to the source file member. This processing includes removing padding and unused parameters.

3. For each non-TDLC controller in the list of controllers: a. A create controller command string is built containing the parameter names and values associated with the controller description. Attachment information (the attached devices and switched line list) may or may not be included depending upon the retrieval type specified by the user. b. For a network retrieval, the names of the attached devices are added to the list of devices to be retrieved. c. The command string is processed and is written to the source file member.

4. For each TDLC line in the list of lines: a. A create...
