# Managed Data Objects

## Change Manager File Repository

The Change Manager file repository is where Change Manager keeps all the file objects (such as Flash archives, Boot images, Manifests, Reports), Jumpstart configuration files, and other private data used by Change Manager software.

You must specify the location of the file repository when you configure Change Manager. The cmsetup(1MCM) script asks you for the location of a directory under which Change Manager can create the file repository. The required disk space depends on the number of Flash archives, Solaris boot images, audit manifests, and other software. You must decide how much file system space you want to allocate for the storage of the Change Manager file repository.

## 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, 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. Change Manager also maintains additional Change Manager-specific data about topology objects in its Metadata tables.

None of the Change Manager management utilities (cminst(1MCM), cmsetup(1MCM), cmuninst(1MCM)) have any effect on the topology data. These utilities are maintained by Sun Management Center and are managed with the usual Sun Management Center tools.

## Change Manager Database Tables

Change Manager maintains additional metadata about topology objects and files in the repository. These metadata are kept in Oracle database tables. These tables contain information about all Change Manager managed objects (for example, flash archives, boot images, and host configuration data).

During configuration, the `cmsetup` script asks the user for the location of the directory under which these database table files are to be created. The required disk space is about 0.5 Gbytes. These files are created strictly for the use of Oracle and require no user management.

## Configuration Data

Various Change Manager operational parameters are maintained in files that are located in the Sun Management Center configuration directory `/var/opt/SUNWsymon/cfg`. These files are created when you install and set up Change Manager. In ordinary use, no user modifications to the configuration data are required. If necessary, however, you can modify the `ichange.cfg` file, as described in ichange.cfg(4CM).
