# Managed Data Objects

The data used and maintained by Change Manager exists in several places:

- Change Manager Repository

- Sun Management Center Topology

- Change Manager Database Tables

- Change Manager Configuration Data

## Change Manager Repository

The Change Manager repository is where files used to perform software deployment and audit tasks are stored. The repository is created and configured when you install the Change Manager server software. You must use Change Manager commands to manage the repository. The following lists some of the files stored in the repository:

- Solaris Flash archives

- Solaris boot images

- Shared profiles

- Manifests

- Reports

When you install the Change Manager server software, you must specify the Change Manager root directory. This directory is the place where all Change Manager data is stored. The directory you specify should be on a file system that has adequate space to store Change Manager data. See Change Manager Server Requirements.

## Sun Management Center Topology

Sun Management Center maintains information about managed hosts and host groups in its topology database. Change Manager operates on the topology by adding and removing entries that correspond to managed hosts. The Sun Management Center Console presents a graphical view of the topology, while Change Manager presents a tabular view of the same data. Note that Change Manager maintains additional data about topology objects in its database tables. Both Change Manager commands and Sun Management Center commands can operate on data contained in the topology.

## Change Manager Database Tables

“Metadata,” additional information about objects in the repository and topology, is maintained in the Change Manager database tables. These tables share a schema in the Oracle database that is used by Sun Management Center. The metadata tables are created and managed by using the Sun Management Center `es-setup` command or the `es-guisetup` command.

During the Change Manager configuration process, you must specify the directory in which to create these database table files. Specify a directory that has about 0.5 Gbytes of available disk space. Note that these database table files are accessed and are updated only by Oracle software.

## Change Manager Configuration Data

Change Manager maintains some of its operational parameters in the Sun Management Center configuration directory, `/var/opt/SUNWsymon/cfg`. This data is created when you install and set up the Change Manager server software. Generally, you do not make modifications to the configuration data. However, you can modify the `ichange.cfg` file, if necessary. See the ichange.cfg(4CM) man page.
