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.

How to install/de-install Multi-Tenancy

First Installation

Follow the instructions of the installation assistant and, at Components, click Multi-Tenancy.

Update Installation

Follow the instructions of the installation assistant and, at Components, click Multi-Tenancy.
For all data that can be tenant specific, <not assigned> is entered as a tenant. Later, the data can be assigned to defined tenants.


Execute an update installation and, at Components, deactivate Multi-Tenancy.

Import Tenants from OpenScape Voice Assistant

1) When you use a version > V3.0 of OpenScape Voice Assistant, open:

Element Manager > Element Manager Configuration > "OpenScape Voice Assistant" Tab

2) Enable Tenants synchronization and click Update Business Groups.
For each business group, a tenant and a location is created.
The names used hereby are constructed from :

Tenants and locations already existing are updated.

Set Up configuration

How to Set Up Tennants =

1)Navigate to Administration > Server Configuration > Tenants.
2)Enter the required number of licenses. You can check the total number via Administration > Server Licenses.
3)If an appropriate location exists already, assign it to the tenant now via Administration > Server Configuration > Tenants > "Locations" Tab. The possible values are displayed in a selection list. It is possible to assign multiple locations. After this, continue with step 6.
4)If no appropriate location should be set up yet, click Save firstly to create the tenant, as this will be required for setting up the location. After this, navigate to Administration > Server Configuration > Location and create a location.
5)Change to Administration > Server Configuration > Location > "Tenants" Tab and assign the location to a tenant. A location can be assigned to only one tenant.
6)Change to Administration > Account Management > Account Configuration and assign the tenant to that account which shall access the data belonging to this tenant.
NOTE: All IP Devices must be assigned to a defined location which is different from the default location. When IP Clients are used, please ensure that all IP addresses available for IP Clients are included when entering IP ranges.
NOTE: If IP Clients are used, please regard that all IP addresses possible for the IP Clients are incorporated when entering IP ranges.
NOTE: The newly created tenant will be assigned to the "admin" account. This assignment cannot be effected via the GUI.
