Field Detail

GROUP_NAME

public static final ConfigParam GROUP_NAME

Names the Replication group.

REP_STREAM_TIMEOUT

public static final DurationConfigParam REP_STREAM_TIMEOUT

The maximum amount of time the replication group guarantees preservation of the log files constituting the replication stream. After this period of time, nodes are free to do log cleaning and to remove log files earlier than this period. If a node has crashed and does not re-join the group within this timeout period it may need to perform a network restore operation to catch up.

REPLAY_TXN_LOCK_TIMEOUT

public static final DurationConfigParam REPLAY_TXN_LOCK_TIMEOUT

The lock timeout for replay transactions.

ENV_SETUP_TIMEOUT

public static final DurationConfigParam ENV_SETUP_TIMEOUT

The max amount of time for the internal housekeeping: recovery, elections, syncup etc., to be accomplished when opening a new handle to an environment.

This timeout does not encompass the time spent making the node consistent if it is a Replica.

Note that the default value is a rather long time, 10 hours to allow for cases where elections may take a long time when other nodes are not available, etc.

ENV_CONSISTENCY_TIMEOUT

public static final DurationConfigParam ENV_CONSISTENCY_TIMEOUT

See Also:

ReplicationConfig.ENV_CONSISTENCY_TIMEOUT

REPLICA_ACK_TIMEOUT

public static final DurationConfigParam REPLICA_ACK_TIMEOUT

See Also:

ReplicationConfig.REPLICA_ACK_TIMEOUT

INSUFFICIENT_REPLICAS_TIMEOUT

public static final DurationConfigParam INSUFFICIENT_REPLICAS_TIMEOUT

See Also:

ReplicationConfig.INSUFFICIENT_REPLICAS_TIMEOUT

MAX_MESSAGE_SIZE

public static final LongConfigParam MAX_MESSAGE_SIZE

The maximum message size which will be accepted by a node (to prevent DOS attacks). While the default shown here is 0, it dynamically calculated when the node is created and is set to the half of the environment cache size. The cache size is mutable, but changing the cache size at run time (after environment initialization) will not change the value of this parameter. If a value other than cache size / 2 is desired, this non-mutable parameter should be specified at initialization time.

CONSISTENCY_POLICY

public static final ConfigParam CONSISTENCY_POLICY

Identifies the default consistency policy used by a replica. Only two policies are meaningful as properties denoting environment level default policies: NoConsistencyRequiredPolicy and TimeConsistencyPolicy. They can be specified as: NoConsistencyRequiredPolicy or TimeConsistencyPolicy(,). For example, a time based consistency policy with a lag of 1 second and a timeout of 1 hour is denoted by the string: TimeConsistencyPolicy(1000,3600000)

DEFAULT_PORT

public static final IntConfigParam DEFAULT_PORT

The port used for replication.

NODE_HOST_PORT

public static final ConfigParam NODE_HOST_PORT

Names the host (or interface) and port associated with the node in the replication group, e.g. je.rep.nodeHostPort=foo.com:5001

NODE_NAME

public static final ConfigParam NODE_NAME

NODE_TYPE

public static final EnumConfigParam<NodeType> NODE_TYPE

NODE_PRIORITY

public static final IntConfigParam NODE_PRIORITY

DESIGNATED_PRIMARY

public static final BooleanConfigParam DESIGNATED_PRIMARY

ELECTABLE_GROUP_SIZE_OVERRIDE

public static final IntConfigParam ELECTABLE_GROUP_SIZE_OVERRIDE

ReplicationMutableConfig.ELECTABLE_GROUP_SIZE_OVERRIDE

MAX_CLOCK_DELTA

public static final DurationConfigParam MAX_CLOCK_DELTA

HELPER_HOSTS

public static final ConfigParam HELPER_HOSTS

HEARTBEAT_INTERVAL

public static final IntConfigParam HEARTBEAT_INTERVAL

DBTREE_CACHE_CLEAR_COUNT

public static final IntConfigParam DBTREE_CACHE_CLEAR_COUNT

CBVLSN_PAD

REPSTREAM_OPEN_TIMEOUT

public static final DurationConfigParam REPSTREAM_OPEN_TIMEOUT

ELECTIONS_OPEN_TIMEOUT

public static final DurationConfigParam ELECTIONS_OPEN_TIMEOUT

ELECTIONS_READ_TIMEOUT

public static final DurationConfigParam ELECTIONS_READ_TIMEOUT

ELECTIONS_PRIMARY_RETRIES

public static final IntConfigParam ELECTIONS_PRIMARY_RETRIES

See Also:

ReplicationConfig.ELECTIONS_PRIMARY_RETRIES

ELECTIONS_MAX_RETRIES

public static final IntConfigParam ELECTIONS_MAX_RETRIES

REP_GROUP_OPEN_TIMEOUT

public static final DurationConfigParam REP_GROUP_OPEN_TIMEOUT

REP_GROUP_READ_TIMEOUT

public static final DurationConfigParam REP_GROUP_READ_TIMEOUT

MONITOR_OPEN_TIMEOUT

public static final DurationConfigParam MONITOR_OPEN_TIMEOUT

MONITOR_READ_TIMEOUT

public static final DurationConfigParam MONITOR_READ_TIMEOUT

REPLICA_TIMEOUT

public static final DurationConfigParam REPLICA_TIMEOUT

See Also:

ReplicationConfig.REPLICA_TIMEOUT

FEEDER_TIMEOUT

public static final DurationConfigParam FEEDER_TIMEOUT

See Also:

ReplicationConfig.FEEDER_TIMEOUT

PRE_HEARTBEAT_TIMEOUT

public static final DurationConfigParam PRE_HEARTBEAT_TIMEOUT

The timeout used on the feeder/replica connection before the heartbeat sequence is initiated. The timeout is long enough to allow for the addition of a new member and the handshake to complete unimpeded. The timeout here is a minute. This config parameter is internal.

TXN_ROLLBACK_LIMIT

public static final IntConfigParam TXN_ROLLBACK_LIMIT
