HP-UX CMGR A.02.01 Administrator's and Developer's Guide

1 Introduction
The HP-UX Configuration Synchronization Manager (CMGR) includes the cmgr tool and libraries.
CMGR tracks specific changes made to configuration files. It can track multiple changes applied to
one configuration file (service) or it can track individual changes to multiple files (services). CMGR
associates changes made to a file with labels and uses the labels to trace and display the changes
that it made to the configuration files.
The cmgr command is a general purpose tool that coordinates the configuration of multiple
subsystems, such as HP-UX compartments, Process Resource management (PRM), IPFilter, and IPSec.
Related configuration changes can be added, viewed, replaced, or deleted as a set.
The cmgr command line arguments are combined with XML based CMGR synchronization templates
that define the actual configuration operations to perform. A synchronization template is an XML file
that uses variables to share configuration information between utilities.
This guide describes how to use the cmgr command and how to create synchronization templates.
1.1 CMGR Architecture
Figure 1.1 depicts the CMGR architecture. Once the administrator invokes the cmgr command, the
selected templates pass the configuration instructions to cmgr. In turn, cmgr calls the appropriate
handler library to modify a configuration file or execute a system command. Each element in a
template has a corresponding handler.
