Changing Server Status to Forced Standby

You can change the status of a server in a cluster to forced standby. A server placed into forced standby status cannot become active. You would do this, for example, to an active server prior to performing maintenance on it. Oracle recommends this method to switch over from an active server or to resolve issues where more than one server in a cluster is active.

When you place a server into forced standby status, the following actions occur:
  • If the server is active, the server is demoted.
  • The server will not assume the active role, regardless of its status or the roles of the other servers in the cluster.
  • The server continues as part of its cluster and reports its status as Forced Standby.
  • The server coordinates with the other servers in the cluster to take the role Standby or Spare.
CAUTION: If you set all servers in a cluster into forced standby status, you can trigger an outage.

To change a server to forced standby status:

  1. From the Platform Setting section of the navigation pane, select Topology Settings.

    The Cluster Configuration page opens; the initial group is All Clusters.

  2. From the content tree, select All Clusters.

    The Cluster Configuration page opens.

  3. Click View for the cluster you want to change.

    The Topology Configuration page opens, displaying information about the cluster.

  4. Click Modify Server-A or Modify Server-B (whichever server needs the status change).
  5. Select Forced Standby.
  6. Click Save.
The server status is changed to forced standby.
