BMC Atrium Discovery Export enables you to publish data from BMC Atrium Discovery directly into relational databases and into all systems that can accept CSV files. BMC Atrium Discovery data is exported by creating an exporter, which is a combination of a mapping set with an adapter configuration. These concepts are explained later in this section.

In previous releases, BMC Atrium Discovery Export was used to export data to BMC Atrium CMDB. That approach is now deprecated; CMDB synchronization is now used to keep BMC Atrium CMDB's data in step with BMC Atrium Discovery.

Exporters

An exporter is the combination of a mapping set and an adapter configuration.

• The mapping set is a set of mapping files. These allow you to determine which data to extract from BMC Atrium Discovery and how to transform it according to the target data model.
• The adapter configuration is used to determine where to publish the data.

Mapping Files and Sets

When performing an export, the exporter needs to know which data to read from the BMC Atrium Discovery datastore and where to place it. It does this with mapping files. A mapping file is an XML document containing the following information:

1. A BMC Atrium Discovery datastore query specifying which data to export.
2. Information on how BMC Atrium Discovery Export must restructure (or transform) the query result in order to make it usable by the system being exported to (i.e. to comply with the remote system's schema).

A mapping set is a set of mapping files that are used to carry out the export. In order to perform an export using a mapping set, the exporter will run the query from each one of the mapping files in the set. A typical export requires more than one query of the datastore. For example, one query to get Hosts, another to get BusinessApplicationInstances, etc.

For further information about mapping file formats see The Mapping File Format.

Adapters and Adapter Configurations

BMC Atrium Discovery Export supports the following adapters:

• RDB – populates relational databases
• CSV – generates CSV files

An adapter configuration typically contains the information needed to connect to the target destination:

• Target host
• Port
• Username
• Password

You can create multiple adapter configurations. For example, if you needed to export data from BMC Atrium Discovery to two Relational Databases ("development" and "production") then you would create two adapter configurations for the RDB adapter, one for each destination.

Permitting Users to Edit the Adapter Configuration

The cmdb-export-administrator user group gives permissions for users to edit the adapter's configuration. To add a user to this group:

1. From the BMC Atrium Discovery appliance user interface, log in to BMC Atrium Discovery.
2. Click the Administration tab in the top-right corner of the window.
3. Click the Users icon in the Security channel.
4. Edit the profiles of any user that you want to administer BMC Atrium Discovery Export. Add them to the cmdb-export-administrator group. Ensure that they are also members of the public group.
