Install the PI AF Application Service in the failover cluster

Before you begin, make sure you complete the tasks in Pre-installation tasks for PI AF in a failover cluster.

The PI AF Application Service must be installed on each Windows server in the failover cluster that will run the PI AF Application Service. This procedure assumes that the failover cluster for the PI AF Application Service has at least two machines. For details, see Architecture for PI AF in a failover cluster.

Note: This procedure must be performed for each node in the failover cluster that will host the PI AF Application Service.

1. Go to the directory where you downloaded the PI Server install kit, and double-click the executable file to launch the installation.

   The Welcome window appears.

2. Click Next.

   The Feature Selection window appears.

3. Select the Individual Features tab.

4. Select only PI AF Application Service.

   This will ensure that only the PI AF Application Service will be installed on this computer.

5. Click Next to proceed with the setup.

   The SQL Server Connection window appears.

6. In the SQL Server Connection window, enter the name of the SQL Server Cluster. If applicable, include the SQL instance name. Enter these names in the following format:

   <SQLClusterName>[\<SQLClusterInstanceName>]

   Where:

   <SQLClusterName> is the name of the SQL Server Cluster into which the PI AF SQL Server database (typically named PIFD) will be installed.

   <SQLClusterInstanceName> is optional and should be included if the SQL Server Cluster was installed with an instance name.

7. To validate the SQL Server connection, try to connect to the SQL Server Cluster by selecting the Validate connection to the SQL Server and the PIFD Database Version check box and clicking Next. If a connection is made, select the Warning Acknowledged check box in the warning that indicates a version of the PI AF SQL Server database already exists and click Next.

8. Ensure that the AF SQL database scripts and AF SQL script execution are NOT selected, and click Next.

   You do not want to create and configure another PI AF SQL Server database.

   The Service Accounts window appears.

9. Specify the domain service account used to run PI AF Application Service and the password for that account.

   The domain service account must be a member of the domain group you configured for the PI AF Application Service. See Configure domain group for the PI AF Application Service.

10. Click Next.

    The Summary window appears, listing the selected features and version numbers scheduled for the installation.

11. Click Install to install the PI AF Application Service.

    The Installation Progress window opens.

    The Complete window opens when the installation is complete.

12. Review the results on the Installation Complete window and verify that there are no errors.

13. Click Close.

14. Ensure the PI AF Application Service is shut down.

15. Repeat the entire procedure described above for each node in the failover cluster that will host the Application Service.
