Enum Constant Detail

• DISABLED

  public static final HighAvailabilityMode DISABLED

  Means HA mode should not be operational.

  When specified for the initial HA mode, this simply turns off HA.

  However if being used to HighAvailabilityManager.changeMode(HighAvailabilityMode), this will cause the node to transition to a ManagementNodeState.FAILED state. Switching to a "master-but-not-part-of-HA" state is not currently supported, as this would be problematic if another node (which was part of HA) then tries to become master, and the more common use of this at runtime is to disable a node from being part of the HA plane.

• AUTO

  public static final HighAvailabilityMode AUTO

  Means auto-detect whether to be master or standby; if there is already a master then start as standby, otherwise start as master.

• STANDBY

  public static final HighAvailabilityMode STANDBY

  Means node must be lukewarm standby; if there is not already a master then fail fast on startup. See ManagementNodeState.STANDBY.

• HOT_STANDBY

  public static final HighAvailabilityMode HOT_STANDBY

  Means node must be hot standby; if there is not already a master then fail fast on startup. See ManagementNodeState.HOT_STANDBY.

• HOT_BACKUP

  public static final HighAvailabilityMode HOT_BACKUP

  Means node must be hot backup; do not attempt to become master (but it can start without a master). See ManagementNodeState.HOT_BACKUP.

• MASTER

  public static final HighAvailabilityMode MASTER

  Means node must be master; if there is already a master then fail fast on startup. See ManagementNodeState.MASTER.

Method Detail

• values

  public static HighAvailabilityMode[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (HighAvailabilityMode c : HighAvailabilityMode.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static HighAvailabilityMode valueOf(java.lang.String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

  java.lang.NullPointerException - if the argument is null
