Configuring highly available single-instance databases on Windows

Before you can back up high availability Oracle single-instance database configurations, you must run the AvamarSDConfiguration.exe program as Administrator, which registers a corresponding virtual client with the Avamar server.

Prerequisites

Each node to be configured must register and activate to the same Avamar server before this configuration, otherwise you may get certification issues when performing browse, backup, and restore operations. There must be one resource which controls the failover of the single-instance database. The Avamar service relies on this resource to a following failover of the Avamar client

Steps

  1. Log in to any of the Oracle cluster nodes where the single-instance database has been configured.
  2. Right-click the file C:\Program Files\avs\bin\ AvamarSDConfiguration.exe and select Run as Administrator.
    The Setup Avamar for Oracle Single-Instance Database dialog box opens.

  3. Type the name of the single-instance database and click Lookup.
    After a successful lookup, if the database has not been configured before, nodes are listed under Available Nodes.
    1. For Var Folder, type a var directory or click Browse to select one.
      NOTE:The var directory all nodes being configured.
    2. For Administrator Server Hostname or IP, type the hostname or IP address of the Avamar server.
    3. For Administrator Server Listen Port, type the port number of the Avamar server listen port.
    4. For Backup Domain for this Client, type the client's backup domain on the Avamar server.
    5. For Connection Port (acport), type the port number of the connection port.
    6. Select the nodes to be configured in the Available Nodes list.
    7. Click Configure.
      NOTE:All fields must be completed before beginning the configuration.
      A message indicates that the configuration was successful. Click OK clear the message. You can start another single-instance database configuration by clicking Next Config.
    After the configuration is complete, EMCagent_database_name is available and ready for failover.
  4. Start the EMCagent_database_name by typing the following at the command line: 
    crsctl start res EMCagent_database_name
    EMCagent_database_name then runs on the node on which the single-instance database instance is running.

Results

Management Console-initiated backups and restores are sent to the node where the EMCagent cluster resource (EMCagent_database_name) is running. If the database instance fails over to another node, the EMCagent_database_name resource is failed over to that node as well. The new node then automatically notifies the Avamar server of the address change for the active node.
