Configuring multitenancy

Multitenancy refers to a situation where a single application on a server supports multiple client organizations. In BMC Helix 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 Helix 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.

Multitenancy is a global setting, it is either enabled or disabled. When you configure multitenancy you select a default company. That becomes the default for all new discovery runs, though you can choose to set any other company name, or none (no company).

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 connection and BMC Remedy ITSM must be installed. You do not need to have performed a synchronization, but the connection must be configured and have been successfully tested, with a user with at least CMDB Demo user permissions. Once this is set up, the Lookup Companies dropdown is populated.

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 Test Connection on the CMDB Sync connection page. Similarly, if you add a new company name to BMC Remedy ITSM, you must refresh the list by clicking Test Connection on any CMDB Sync connection page.

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