Enum Constant Summary

Enum Constants

Enum Constant and Description
ACTIVE the service is active and running on one server.
INACTIVE_FAILED_CRITICAL the service was previous active but failed due to critical error last time which means manual intervention of Administrator is required normally.
INACTIVE_FAILED_UNHEALTHY the service was previous active but failed due to the service is unhealthy; see SingletonServicesState.FAILED_STATE
INACTIVE_MANAGED the service was previous active but was deactivated since DynamicLoadbalancer returned a action plan to deactivate this service from previous active state.
INACTIVE_OTHERS the service is inactive due to other reasons, or has never been activated, or its hosting server is killed or crashed suddenly.
INACTIVE_SERVER_SHUTDOWN the service was previous active but was deactivated due to administrative shutdown, either graceful or force shutdown, of the hosting server.

Enum Constant Detail

ACTIVE

public static final DynamicLoadbalancer.State ACTIVE

the service is active and running on one server. It can be migrated to another server, or deactivated from current server, if needed.

INACTIVE_FAILED_CRITICAL

public static final DynamicLoadbalancer.State INACTIVE_FAILED_CRITICAL

the service was previous active but failed due to critical error last time which means manual intervention of Administrator is required normally. However, it still could be migrated or activated if the DynamicLoadbalancer implementation believe it is safe and necessary to do so. It is DynamicLoadbalancer implementation's responsibility for the decision.
Core implementation note: Currently, INACTIVE_FAILED_CRITICAL maps to SingletonServicesStateManager.MANUAL_STATE

INACTIVE_FAILED_UNHEALTHY

public static final DynamicLoadbalancer.State INACTIVE_FAILED_UNHEALTHY

the service was previous active but failed due to the service is unhealthy; see SingletonServicesState.FAILED_STATE

INACTIVE_SERVER_SHUTDOWN

public static final DynamicLoadbalancer.State INACTIVE_SERVER_SHUTDOWN

the service was previous active but was deactivated due to administrative shutdown, either graceful or force shutdown, of the hosting server. see SingletonServicesState.SHUTDOWN_STATE. it currently only is used for FR MT, but we could enhance it so always keep state for MigrateableConfigGroup services.

INACTIVE_MANAGED

public static final DynamicLoadbalancer.State INACTIVE_MANAGED

the service was previous active but was deactivated since DynamicLoadbalancer returned a action plan to deactivate this service from previous active state.

INACTIVE_OTHERS

public static final DynamicLoadbalancer.State INACTIVE_OTHERS

the service is inactive due to other reasons, or has never been activated, or its hosting server is killed or crashed suddenly.

Method Detail

values

public static DynamicLoadbalancer.State[] 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 (DynamicLoadbalancer.State c : DynamicLoadbalancer.State.values())
    System.out.println(c);

Returns:

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

valueOf

public static DynamicLoadbalancer.State 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
