# Setting Up Change Manager

## Initialization

When you use `cminst` to install the Change Manager software, you are asked whether the Change Manager data is to be configured. If setup is requested, the metadata table files, file repository structure, and required Change Manager configuration files are all created. If you elect not to configure the Change Manager data during installation, the `cmsetup` script must be run before Change Manager functionality is available.

Once the Change Manager data elements have been configured, you can run `cmsetup` at any time to reinitialize or remove Change Manager data. Reinitializing resets the metadata tables to factory settings and optionally removes Change Manager data. Reinitializing without removing data leaves the repository data files in place, but clears all Change Manager metadata. In either case, Change Manager remains functional and is still available after the operation is completed.

## Uninstallation

The `cmuninst` command removes all Change Manager components and, optionally, data. If you elect not to remove Change Manager data, the contents of the file repository and Change Manager metadata tables are left in place. A subsequent reinstallation of Change Manager thus finds the existing data and, if you choose, uses this data rather than reinitializing the data.

To remove Change Manager data without removing the underlying Change Manager software components, use `cmsetup` as described previously.

Removing or initializing Change Manager data does not affect the topology, which is maintained by Sun Management Center.

## Backup and Restore

Backup of Change Manager data involves both Change Manager database tables and the Change Manager file repository. You can back up the Change Manager database files by using the Sun Management Center command `es-backup`. The `es-backup` command backs up both Sun Management Center database files and Change Manager database files, including all Change Manager configuration data kept under `/var/opt/SUNWsymon/cfg`. The `es-restore` command restores data backed up by `es-backup`. For more information about `es-backup` and `es-restore`, see the Sun Management Center user documentation.

You can back up the Change Manager file repository by using ordinary Solaris operating environment file system tools. You must restore the repository after you run `es-restore` to restore Change Manager and Sun Management Center metadata.
