Multitenancy

Multitenancy refers to a situation where a single application on a server supports multiple client organizations. In BMC Atrium Discovery, this means the ability to scan the estates of multiple organizations, and to assign a company name attribute to that scan. Any CMDB CIs created as a result of that scan can be assigned the appropriate company name. The BMC Atrium Discovery data is not segregated for multiple tenants, it is simply a way pass company names to the CMDB.

The company name is assigned to the cdm_company attribute on the Discovery Run node. This is mapped onto CMDB CIs created as a result of that scan and assigned to the Company attribute.

Important considerations when using multitenancy

Multitenancy obtains company names from BMC Remedy ITSM through BMC Atrium CMDB. Therefore, to obtain company names, you must have a working CMDB Sync and BMC Remedy ITSM must be installed. You do not need to have performed a synchronization, but the connection must be configured and working, with a user with at least CMDB Demo user permissions. Once this is set up, the Lookup Companies button on the CMDB Sync is displayed.

The company list on the appliance is not automatically refreshed from the BMC Atrium CMDB. If you do not see a company that you are expecting to see, refresh the list by clicking Lookup Companies on the CMDB Sync page. Similarly, if you add a new company name to BMC Remedy ITSM, you must refresh the list by clicking Lookup Companies.

If there is no company information available from ITSM, the Default Company does not contain any company names. Instead, it displays No Company.

Multitenancy in Consolidation deployments

In consolidating systems with multiple Scanning appliances feeding a Consolidation appliance, it is the Consolidation appliance that requires the CMDB sync connection. Scanning appliances should not be configured to synchronize with the CMDB, they should send data to the Consolidation appliance. As part of the communication that occurs between associated Consolidation and Scanning appliances, the company list on the Consolidation appliance is automatically populated to the Scanning appliances. However, the list on the consolidating appliance is not automatically refreshed from the BMC Atrium CMDB.

When you are working on a Scanning appliance, and you do not see a company that you are expecting to, you must log onto the Consolidation appliance and refresh the list on the Consolidation appliance by clicking Lookup Companies on the CMDB Sync page.
