[. . . ] The following figure illustrates a cluster with a load balancer and with the Breeze Presentation platform on three computers. Load balancer Breeze Presentation platform Breeze Presentation platform Breeze Presentation platform Breeze database (Microsoft SQL Server 2000) To set up clustered Breeze Presentation platforms: 1 Install the Breeze Presentation platform on each computer that will be in the cluster. For information on installing the Breeze Presentation platform, see the Macromedia Breeze Installation Guide. During installation, you use the same license key each time you install the Breeze Presentation platform. 2 Set configuration properties in the custom. ini file belonging to one of the Breeze Presentation platforms in the cluster. For information on setting configuration properties for the Breeze Presentation platform, see Chapter 4, "Configuring the Breeze Presentation Platform, " in the Macromedia Breeze Installation Guide. Some of the properties you need to set in the custom. ini configuration file apply to the Breeze database. For information on these properties and on setting up the Breeze database, see Chapter 3, "Setting up the Breeze Database, " in the Macromedia Breeze Installation Guide. 3 Copy the custom. ini configuration file to the installation folder of all the other Breeze Presentation platforms in the cluster. All Breeze Presentation platforms must have identical custom. ini files. Before you start one of the Breeze Presentation platforms, you need to start Microsoft SQL Server. 6 Clustering Breeze Presentation Platforms Verifying failover for HTTP requests This section describes a procedure for verifying that your Breeze Presentation platform cluster provides failover in the event that one of the computers in the cluster fails. The procedure assumes that there are two computers in the cluster, Computer1 and Computer2. The steps for verifying failover with more than two computers is very similar. The basic approach in the procedure that follows is to demonstrate failover when you are using the Breeze Manager, a web application within the Breeze Presentation platform. If the computer you are accessing for the Breeze Manager fails and you can continue to use the Breeze Manager without logging in again and without interruption, failover is successful. To verify failover for HTTP requests in a Breeze Presentation platform cluster with two computers: 1 Make sure that the Breeze Presentation platform on Computer1 is started and that the Breeze Presentation platform on Computer2 is stopped. Before you start the Breeze Presentation platform, Microsoft SQL Server 2000 must be running. To start the Breeze Presentation platform: Select Start > Programs > Macromedia > Macromedia Breeze 3 > Start Breeze Server. To stop the Breeze Presentation platform: Select Start > Programs > Macromedia > Macromedia Breeze 3 > Stop Breeze Server. You can log in to the Breeze Manager from the following URL: http://admin_host/servlet/ admin. In the URL, admin_host is the host name you entered as the value of the ADMIN_HOST property in the Breeze Presentation platform custom. ini configuration file (see step 2 under "Setting up a cluster of Breeze Presentation platforms" on page 6). When you log in, the Breeze Manager home page opens. [User name] Verifying failover for HTTP requests 7 3 Start the Breeze Presentation platform on Computer2. 5 Click the Reports tab. If failover is successful, the Breeze Manager Reports page opens. [. . . ] c Click the New Content button and then follow the steps displayed in your browser for adding content.
