2 Communicating With the DNS
Name Manager

This section describes how a management application sends Subsystem Programmatic
Interface (SPI) messages to the DNS name manager process and receives SPI responses
in return. Management applications also retrieve event messages generated by the
DNS name manager process.
Each network node on which DNS is installed has a name manager. The DNS name
manager is a management process through which DNSCOM and other applications
request input to and output from the DNS database on their behalf.
Starting a DNS Name
Manager Process
Before your management application can send commands to a DNS name manager,
you must first start a name manager process. You can start a name manager process in
one of three ways: interactively, using DNSCOM; through TACL; or
programmatically. All methods have the same result and appear the same to the name
manager.
After a name manager process is started, it can accept up to 64 open requests from
DNSCOM or other management applications. Each open request received by the
name manager provides a means of communication between DNS and a management
application. Open requests received by a name manager process may be issued
interactively or programmatically.
Starting the Name Manager
Interactively Using
DNSCOM
To run DNSCOM, enter DNSCOM, at your TACL prompt. To start a name manager
process interactively, enter the START DNS command at the DNSCOM prompt.
(Details about running DNSCOM are provided in the Distributed Name Service (DNS)
Management Operations Manual.
