This wiki page will contain a short introduction to and will explain howto use the Devices Emergency Rescue Tool
- OpenStage and DeskPhone IP devices are usually supplied with Software via DLS (Deployment Server) or DLI (Integrated Deployment Service). DERT (Devices Emergency Rescue Tool) is intended only for exceptional cases in which a phone must be updated individually due to technical problems.
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.
