The PI AF application service must be installed on a machine that is separate from other machines used in a mirrored SQL Server session.

  1. Run the PI Server install kit to install the PI AF application service on a separate machine.

    See Install the PI AF application service for a description of the installation process.

  2. Verify that the PI AF application service runs under a domain account. For details, see Configure domain group for the PI AF Application Service.

  3. Update the AFService.exe.config file so it references the failover partner. After making changes, save the file.

    Follow the instructions in Modify the AFService.exe config file, ensuring the connection string includes the failover partner entry.

  4. Restart the PI AF server.
