Prerequisites: Configuring database mirroring

  • Configure the principal server and mirror server to permit access from remote computers.
  • Configure the principal server and mirror server to have the same permissions.
  • Set up a witness server that you will use to monitor the principal server.
  • Configure the 
    Microsoft SQL Server
     Agent to use a domain user account with the same local administrative permissions as the 
     account that runs the 
    BlackBerry UEM
  • Verify that the domain user account has permissions for both the principal server and mirror server.
  • Verify that the DNS server is running.
  • On each computer that hosts a 
    BlackBerry UEM
     database instance, in the 
    SQL Server
     2012 Native Client, turn off the Named Pipes option. If you choose to not turn off the Named Pipes option, visit to read article 34373.
  • To review additional prerequisites for your organization’s version of 
    Microsoft SQL Server
    , visit to read Database Mirroring - SQL Server 2012 or Database Mirroring - SQL Server 2014.
  • If the mirror database uses the default instance, the 
    BlackBerry UEM
     components can connect to the mirror database using the default port 1433 only, not a custom static port. This is due to a limitation of 
    Microsoft SQL Server
     2005 and later. For more information about this issue, see SQL 2005 JDBC Driver and Database Mirroring.
