Prerequisites: Configuring database mirroring
- Configure the principal server and the mirror server to permit access from remote computers.
- Configure the principal server and the mirror server to have the same permissions.
- Set up a witness server that you will use to monitor the principal server. For more information, see Database Mirroring Witness – SQL Server 2008 R2 or Database Mirroring Witness – SQL Server 2012.
- Configure the Microsoft SQL Server Agent to use a domain user account with the same local administrative permissions as the Windows account that runs the BlackBerry Enterprise Service 10 services.
- Verify that the domain user account has permissions for both the principal server and the mirror server.
- Verify that the DNS server is running.
- If you configured high availability for BlackBerry Enterprise Service 10 components, change the failover type from automatic to manual until you configure database mirroring.
- Configure the principal server and the mirror server to use static port 1433 only.
- On the computers that host the BlackBerry Enterprise Service 10 components, in the Microsoft SQL Server Native Client, turn off the Named Pipes option.
