In the following, the administration of data from multiple clients (=tenants) with one single DLS installation is described.

This function is available only when DLS multi-tenancy has been installed. This will be asked by the installation assistant.

With multi-tenancy masks, the selection menu Tenants is available. Otherwise, it is greyed out.

When a a new object is created without selecting a tenant, an error message appears.

With multi-tenancy masks, it will make a difference whether the object is assigned to a tenant or not, that is, in the tool bar under Tenant, either the tenant’s name or <not assigned> will be displayed.

When objects are added which require a license, the tenant specific limits are checked. If a tenant is created or changed, the license dependent data are checked. The respective alarm thresholds are set tenant specific (see Section 6.3.1, "Tenants").

Basically, there is a difference between tenant dependent and tenant independent alarms.

The tenancy feature is stored in the database - but this feature is activated during setup and so it is system dependent and NOT database dependent.Hence it is possible to restore a DLS database that previously contained tenancy relations to a DLS installation where the tenancy feature is not installed.

In this rare scenario, if you have installed a system without tenant and restore a tenant database you will not see any tenants and no-tenant dependent objects afterwards since this feature was never installed before.
