Chapter 1 Automatic Server Failover Introduction This chapter covers the following topics: • Introduction • Summary of the Way it Works • Installing the Failover Hardware Components • Terminology Introduction The automatic server failover mechanism in Avid Interplay allows client access to the Interplay Engine in the event of failures or during maintenance, with minimal impact on the availability. A failover server is activated in the event of application, operating system, or hardware failures.
Chapter 1 Automatic Server Failover Introduction The following diagram illustrates the failover cluster architecture. Two-Node Cluster in Unity MediaNetwork environment Network Switch Interplay clients Private network for heartbeat Interplay Engine - Cluster Node Intranet Cluster shared RAID array Interplay Engine - Cluster Node Fibre Switch n 14 If you are already using clusters, the Avid Interplay Engine won't interfere with your current setup.
Summary of the Way it Works Summary of the Way it Works When the Microsoft® Windows® cluster service is running on the machines and the server is deployed in cluster mode, the Interplay Engine and its accompanying services are exposed to users as a virtual server. To clients, however, connecting to the clustered virtual Interplay Engine appears to be the same process as connecting to a single, physical machine. The user or client application does not know which node is actually hosting the virtual server.
Chapter 1 Automatic Server Failover Introduction Installing the Failover Hardware Components A failover cluster system includes the following components: • Two Interplay Engine nodes or two Interplay Archive nodes (SR2400 or SR2500) • Cluster shared storage - RAID array SR2400 Slot Locations The SR2400 is supported as a server for the Interplay applications. This section describes the slot locations that are specific to the Interplay components in a cluster configuration.
Installing the Failover Hardware Components SR2500 Slot Locations The SR2500 is supported as a server for the Interplay applications. This section describes the slot locations that are specific to the Interplay components in a cluster configuration. Use the following figure and table as guides to how your SR2500 is configured in an Interplay cluster environment.

Ask your system administrator for more information on this.
Installing the Interplay Engine on the First Node Specifying the Interplay Engine Name 1. Choose the public names for the Avid Interplay Engine by typing the following values: - The Network Name will be associated with the virtual IP Address that you've entered in the previous Interplay Engine Details dialog box. It is registered in the DNS so that clients can find the server without having to specify its address. The name must not exist yet.
Chapter 2 Automatic Server Failover Installation Specifying the Destination Location The Destination Location is the location of the Interplay Engine program files. 1. Do one of the following: c t Keep the default. t Type another location or use the Browse button to select another location.The installation needs to be on a local disk of the host and not on a shared cluster disk. It is also essential that the same location is used on the other machine.
Installing the Interplay Engine on the First Node Specifying the Default Database Folder Specify a default database folder. The database folder is the place where the database data is stored. 1. Type or browse to the database folder name. This folder should reside on the shared drive that is owned by the resource group of the server.
Chapter 2 Automatic Server Failover Installation Specifying the Share Name Specify a share name used by the File Share resource. 1. Type the share name. Avid recommends you use the default sharing name of "WG_Database$". This name is visible on all client platforms, such as Windows 98, Windows ME, Windows NT Windows 2000 and Windows XP. Other sharing names such as "Interplay Database" are only reachable from Windows NT, Windows 2000 and Windows XP.
Installing the Interplay Engine on the First Node Specifying the Configuration Server The configuration server setting indicates whether this server is to act as a Central Configuration Server. Set for both Interplay Engines Use this option for Interplay Archive Engine A Central Configuration Server (CCS) is an Avid Interplay Engine with a special module which is used to store server and database-spanning information.
Chapter 2 Automatic Server Failover Installation If you do select “Another Avid Interplay Engine,” you need to type the name of the other server to be used as the CCS in the next dialog box. For example, use this option when using an Interplay Archive Engine as the CCS. If you specify the wrong CCS, you can change the setting later on the server machine in the Windows Registry under: HKEY_LOCAL_MACHINE/Software/Avid Technology/Workgroup/DatabaseServer The string value CMS specifies the server.
Installing the Interplay Engine on the First Node 1. Type the Cluster Service Account user login information. The "Server Execution User" is the Windows domain user that runs the Interplay Engine and the cluster service. This user needs to have administrative access to the file server. This user must be the one that was used to set up the cluster service. See “Before You Start: Preparation” on page 28. c c The installer cannot check the username or password you type in this dialog.
Chapter 2 Automatic Server Failover Installation 2. Click Next. The Enable Email Notification dialog box opens if you are installing the Avid Interplay Engine for the first time. Enabling Email Notifications The first time you install the Avid Interplay Engine, the Enable Email Notification dialog box opens.

If you need to change any configuration files, make sure that the Avid Workgroup Disk resource is online; the configuration files can be found on the resource drive in the Workgroup_Data folder. Updating a Clustered Installation A major benefit of a clustered installation is that you can perform rolling upgrades.
Chapter 2 Automatic Server Failover Installation c Do not move the Avid Workgroup resource group over yet. 4. Make sure that first node is online. Update the installation on the first node using the WorkgroupServer.exe installer. Select the Typical mode so that all values are reused. This restarts the first node. 5. During installation, the installer asks you to move the resource groups to the second node. Move the resource groups. Then click OK in the installation dialog box to continue.
Uninstalling the Interplay Engine On a cluster system, (after both nodes have been upgraded), do the following on the active node: Copy S:\WorkgroupData\Apache\conf\workgroup.080807-101852.xml over the file S:\WorkgroupData\Apache\conf\workgroup.xml n On a cluster system, the following file is installed on both nodes: C:\Program Files\Avid\Avid Interplay Engine\Data\Apache\conf\workgroup.xml. These files are not currently used and do not need to be edited or overwritten.
Chapter 2 Automatic Server Failover Installation 4. (Option) If you plan to reinstall the Interplay Engine after you uninstall it, make sure you rename or remove the workgroup_data and workgroup_database directory on the shared storage to prevent any problems due to corrupt or missing data. c 88 The uninstall mechanism of the cluster resources only functions properly if the names of the resources or the resource group were not changed. Never change these names.
Chapter 3 Automatic Server Failover Tips and Rules This chapter provides some important tips and rules to use when configuring the automatic server failover. Don't Access the Machines Directly Don’t access the machines directly. Refer to the projects using the "virtual" network name or IP address that has been assigned to the resource group; never use the actual physical names or IP addresses of the machines that are part of the cluster.
Chapter 3 Automatic Server Failover Tips and Rules Do Not Install the Server on a Shared Disk The Interplay Engine must be installed on the local disk of the cluster nodes and not on a shared resource. This is because local changes are also necessary on both machines. Also, with independent installations you can later use a rolling upgrade approach, upgrading each node individually without affecting the operation of the cluster.
