Other UCS Configuration

Multi-tenancy Support

Release 9.1 supports multi-tenancy. (Application) tenants are now dynamically taken into account in UCS 9.1—previously UCS had to be restarted. However, the application and the cluster must have the same Tenant(s), so if you change the Tenant(s) of the application, you need to apply the same changes to the cluster, or UCS will not restart the next time.

Access to Configuration Server

UCS needs read access to the Configuration Server database for the Tenant(s) associated with this UCS.

TLS Connection as Windows Service

When UCS has Transport Layer Security (TLS) configured, either as a server on its ESP or HTTP ports, or as a client in its connection to Configuration Server and Message Server, follow these steps to enable it as a Windows Service:

  • Solution 1:
  1. Select the Windows service related to UCS.
  2. Select the Log On tab. The default setting is Log on as local system account.
  3. Select Log on as this account and provide the login/password of a local host user.
  • Solution 2:
  1. Install the certificate in the local system account. To do that, start Microsoft Management Console (MMC) with the following command line as administrator: psexec -i -s mmc then refer to the Genesys Security Deployment Guide to know how to manage certificates in MMC.

Using iPv6 on the LCA Connection

Unlike UCS 8.5.2, by default UCS 9.1 uses iPv4 on the LCA connection. To enable it to use iPv6, set the following environment variable as shown here:


To change the default selection from iPv4 to iPv6, set the following environment variable from:




Support for load-balancing requests from Interaction Server to UCS

Interaction Server is able to load-balance requests to UCS 9.1 to improve performance. However, you need to make sure that all routing blocks—such as "Stop Processing"—that use UCS must have "Application Name" left empty, otherwise the request will always go to the target UCS application.
