Install and configure the Presence service cluster

The server that hosts the Presence service does not require a separate database when it is installed with a service that uses a database (for example, BEMS_Core if Push notifications service (Mail) is installed on the same server). The Presence service requires access to a database when it is installed as a separate cluster.
Before you add a Presence instance for disaster recovery, complete the following actions:
  • If your environment has separate Front End Pools or additional Trusted Application Pools, make sure that you add the correct permissions. Note: The Presence and Connect service can use the same Trusted Application Pool for disaster recovery.
  • Make sure that the appropriate network ports are open to allow the servers that host the Presence service within your secondary site to communicate with the database, Skype for Business Server, or Skype for Business database, and BlackBerry Proxy servers in your secondary and primary site.
  1. Install BEMS on each server that will host the Presence service at the primary site. Select the Presence option in each case. If only Presence is installed on a server, use a new database to create a new cluster dedicated to Presence (for example, BEMS_Core2). If Presence is installed on a server with a service that uses a database (for example, Push notifications service (Mail)), Presence uses the BEMS_Core database.
  2. Install BEMS on each server that will host the Presence service at the secondary site. Select the Presence option in each case. Depending on your environment configuration in step 1, add the servers to the same database or the new database.
  3. At the primary site, in the BEMS dashboard (BEMS System Settings > BlackBerry Configuration > BlackBerry Dynamics), configure one or more BlackBerry Proxy servers from one or more clusters in the primary site. This list is used only for startup. Clear the 'Apply to other nodes in this BEMS cluster' check box. Repeat this step on each server that hosts the Presence service in the primary site.
  4. At the secondary site, in the BEMS dashboard (BEMS System Settings > BlackBerry Configuration > BlackBerry Dynamics), configure one or more BlackBerry Proxy servers from one or more clusters in the secondary site. This list is used only for startup. Clear the 'Apply to other nodes in this BEMS cluster' check box. Repeat this step on each server that hosts the Presence Presence service in the secondary site.
  5. Configure the appropriate instant messaging (for example, Skype for Business) and Active Directory settings (for example, the Skype for Business front-end pool).
  6. Stop the services on the servers at the secondary site to prevent the disaster recovery nodes from contributing to normal cluster operations (for example, presence status of users).
  7. In the BlackBerry UEM management console, in the BlackBerry Dynamics connectivity profiles that are assigned to users, do the following for each server that hosts the Presence service. Depending on your environment configuration, additional server-side services might be required. For more information about BEMS services and server-side bindings, see the Additional information.
    1. At the primary site, under App servers for BlackBerry Presence Service, set the Priority to PRIMARY and set the Primary BlackBerry Proxy cluster to BPCluster1.
    2. At the secondary site, under App servers for BlackBerry Presence Service, set the Priority to SECONDARY or TERTIARY and set the Primary BlackBerry Proxy cluste to BPCluster2.
