Install and configure the
BEMS-Presence
 cluster

The
BEMS-Presence
 server 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
BEMS-Presence
 server requires access to a database when it is installed as a separate cluster.
Before you add a
BEMS-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:
    BEMS-Presence
     and
    BEMS-Connect
     can use the same Trusted Application Pool for disaster recovery.
  • Make sure that the appropriate network ports are open to allow the
    BEMS-Presence
     servers within your secondary site to communicate with the database,
    Skype for Business
     Server or
    Microsoft Lync Server
    ,
    Microsoft Lync Server
     or
    Skype for Business
     database, and
    BlackBerry Proxy
     servers in your secondary and primary site.
  1. Install
    BEMS
     on each
    BEMS-Presence
     server 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
    BEMS-Presence
     server 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 for each
    BEMS-Presence
     instance 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 for each
    BEMS-Presence
     instance in the secondary site.
  5. Configure the appropriate instant messaging (for example,
    Skype for Business
    ) and
    Active Directory
     settings (for example, the
    Lync
     front-end pool).
  6. Stop the services on the servers at the secondary site.
  7. In the
    BlackBerry UEM
     management console, in the Default
    BlackBerry Dynamics
     connectivity profile, do the following. 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. Under
      App servers for BlackBerry Presence Service
      , for each of the
      BEMS-Presence
       servers at the primary site, set the
      Priority
       to PRIMARY and set the
      Primary BlackBerry Proxy cluster
       to BPCluster1.
    2. Under
      App servers for BlackBerry Presence Service
      , for each of the
      BEMS-Presence
       servers at the secondary site, set the
      Priority
       to SECONDARY or TERTIARY and set the
      Primary BlackBerry Proxy cluster
       to BPCluster2.
