public static final String SKIP_NODENAME_VALIDATION
```

    Constant Field Values
  - SKIP_HELPER_HOST_RESOLUTION
```
public static final String SKIP_HELPER_HOST_RESOLUTION
```

    Constant Field Values
  - GROUP_NAME
```
public static final ConfigParam GROUP_NAME
```
    Names the Replication group.
  - REP_STREAM_TIMEOUT
```
public static final DurationConfigParam REP_STREAM_TIMEOUT
```
    Deprecated. see ReplicationConfig.REP_STREAM_TIMEOUT
  - MIN_RETAINED_VLSNS
```
public static final IntConfigParam MIN_RETAINED_VLSNS
```
    Deprecated. and no longer used as of JE 7.5. Reserved files are now retained based on available disk space -- see EnvironmentConfig.MAX_DISK and EnvironmentConfig.FREE_DISK should be used instead. However, this param is still used when some, but not all, nodes in a group have been upgraded to 7.5 or later.
    
    MIN_RETAINED_VLSNS was never exposed in the public API, although we did ask several users to configure it in the past, so we shouldn't delete the param definition.
  - MIN_VLSN_INDEX_SIZE
```
public static final IntConfigParam MIN_VLSN_INDEX_SIZE
```
    Unpublished (for now at least) parameter describing the minimum size of the VLSNIndex as a number of VLSNs. Once the index grows to this size, it will not get smaller due to head truncation by the cleaner.
    When a disk limit is violated we will have already deleted as many reserved files as possible. If space is made available and write operations can resume, we need to ensure that each node has a large enough VLSNIndex to perform syncup, etc.
    
    This limit is enforced on both master and replicas. It is particularly important on replicas because feeders will not prevent VLSN index head truncation.
  - TEST_CBVLSN
```
public static final BooleanConfigParam TEST_CBVLSN
```
    Can be used by tests to prevent the GlobalCBVLSN from being defunct, even when all nodes are DEFUNCT_JE_VERSION or higher.
  - REPLICA_RECEIVE_BUFFER_SIZE
```
public static final IntConfigParam REPLICA_RECEIVE_BUFFER_SIZE
```
    See Also:
    
    ReplicationConfig.REPLICA_RECEIVE_BUFFER_SIZE
  - REPLICA_MESSAGE_QUEUE_SIZE
```
public static final IntConfigParam REPLICA_MESSAGE_QUEUE_SIZE
```
    The size of the message queue used for communication between the thread reading the replication stream and the thread doing the replay. The default buffer size has been chosen to hold 500 single operation transactions (the ln + commit record) assuming 1K sized LN record.
    Larger values of buffer size may result in higher peak memory utilization, due to a larger number of LNs sitting in the queue. The size of the queue itself is unlikely to be an issue, since it's tiny relative to cache sizes. At 1000, 1kbyte LNs it raises the peak utilization by 1MB which for most apps is an insignificant rise in the peak. Note that the parameter is lazily mutable, that is, the change will take effect the next time the node transitions to a replica state.
  - 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
```
    See Also:

  - ENV_UNKNOWN_STATE_TIMEOUT
```
public static final DurationConfigParam ENV_UNKNOWN_STATE_TIMEOUT
```
    See Also:

```
    See Also:

```
    See Also:
    
    ReplicationConfig.INSUFFICIENT_REPLICAS_TIMEOUT
  - ARBITER_ACK_TIMEOUT
```
public static final DurationConfigParam ARBITER_ACK_TIMEOUT
```
    See Also:
    
    ReplicationConfig.ARBITER_ACK_TIMEOUT
  - ENABLE_GROUP_ACKS
```
public static final BooleanConfigParam ENABLE_GROUP_ACKS
```
    Internal parameter enable use of the group ack message. It's on by default since protocol version 6.
  - 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(permissibleLag,timeout). 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 BooleanConfigParam ALLOW_ARBITER_ACK
```
  - ARBITER_OUTPUT_QUEUE_SIZE
```
public static final IntConfigParam ARBITER_OUTPUT_QUEUE_SIZE
```
  - DESIGNATED_PRIMARY
```
public static final BooleanConfigParam DESIGNATED_PRIMARY
```
  - FEEDER_TCP_NO_DELAY
```
public static final BooleanConfigParam FEEDER_TCP_NO_DELAY
```
  - FEEDER_BATCH_NS
```
public static final IntConfigParam FEEDER_BATCH_NS
```
    The time interval in nanoseconds during which records from a feeder may be batched before being written to the network. Larger values can result in fewer network packets and lower interrupt processing overheads. Since the grouping is only done when the feeder knows that the replica is not completely in sync, it's unlikely to have an adverse impact on overall throughput. Consequently this parameter is retained as an internal tuning knob. The HEARTBEAT_INTERVAL parameter serves as a ceiling on this time interval. Parameter values larger than HEARTBEAT_INTERVAL are truncated to HEARTBEAT_INTERVAL.
  - FEEDER_BATCH_BUFF_KB
```
public static final IntConfigParam FEEDER_BATCH_BUFF_KB
```
    The size in KB used to batch outgoing feeder records. Upon overflow the existing buffer contents are written to the network and a new batch is initiated. The default value is 64K to take advantage of networks that support jumbo frames.
  - ELECTABLE_GROUP_SIZE_OVERRIDE
```
public static final IntConfigParam ELECTABLE_GROUP_SIZE_OVERRIDE
```
    See Also:
    
    ReplicationMutableConfig.ELECTABLE_GROUP_SIZE_OVERRIDE
  - RESET_REP_GROUP
```
public static final BooleanConfigParam RESET_REP_GROUP
```
    An internal option, accessed only via the utility DbResetRepGroup utility, to reset a replication group to a single new member when the replicated environment is opened.
  - RESET_REP_GROUP_RETAIN_UUID
```
public static final BooleanConfigParam RESET_REP_GROUP_RETAIN_UUID
```
    An internal option, used with RESET_REP_GROUP, that causes the reset of the replication group to retain the original group UUID and to not truncate the VLSN index. Use this option when converting a SECONDARY node to an ELECTABLE node when recovering a replication group.
  - IGNORE_SECONDARY_NODE_ID
```
public static final BooleanConfigParam IGNORE_SECONDARY_NODE_ID
```
    An internal option to allow converting an ELECTABLE node to a SECONDARY node by ignoring the electable node ID stored in the local rep group DB.

```
    The master re-broadcasts the results of an election with this period.
  - ELECTIONS_PRIMARY_RETRIES
```
public static final IntConfigParam ELECTIONS_PRIMARY_RETRIES
```
    See Also:
    
    ReplicationConfig.ELECTIONS_PRIMARY_RETRIES

```
  - REPLICA_GROUP_COMMIT_INTERVAL
```
public static final DurationConfigParam REPLICA_GROUP_COMMIT_INTERVAL
```
  - SO_REUSEADDR
```
public static final BooleanConfigParam SO_REUSEADDR
```
    Used to force setting of SO_REUSEADDR to true on the HA server socket when it binds to its port. Note that the default is false, meaning that the socket has the system-specific default setting associated with it. We set it to true primarily in unit tests where the interacting HA processes are all on the same machine and use of this option is safe. This option is currently intended just for internal test use.
  - BIND_INADDR_ANY
```
public static final BooleanConfigParam BIND_INADDR_ANY
```
    This option was motivated by the BDA. The BDA uses IB for intra-rack node communications and 10gigE for inter-rack node communications. DNS is used to map the hostname to different IP addresses depending on whether the hostname was resolved from within the rack or outside it. The host thus gets HA traffic on both the IB and 10gigE interfaces and therefore needs to listen on both interfaces. It does so binding its socket using a wild card address when this option iks turned on.
    
    See Also:
    
    ReplicationConfig.BIND_INADDR_ANY
  - SO_BIND_WAIT_MS
```
public static final IntConfigParam SO_BIND_WAIT_MS
```
    Determines how long to wait for a bound socket to come free. This option can be useful when dealing with sockets in the TIME_WAIT state to come free so they can be reused. Attempts are made to retry binding to this period at intervals of 1 second until the port is bound successfully, or this wait period is exceeded. A value of zero means that there are no retries. It does not make sense to wait too much longer than the 2 min TIME_WAIT period, but we allow waiting as long as 2.5 min to account for race conditions. This option is currently intended just for internal test use.
  - FEEDER_MANAGER_POLL_TIMEOUT
```
public static final DurationConfigParam FEEDER_MANAGER_POLL_TIMEOUT
```
    Internal parameter used to determine the poll timeout used when accepting incoming feeder connections. This timeout also determines the frequency of various housekeeping tasks, e.g. detection of a master to replica change, etc.
  - FEEDER_TIMEOUT
```
public static final DurationConfigParam FEEDER_TIMEOUT
```
    See Also:
    
    ReplicationConfig.FEEDER_TIMEOUT
  - TRANSFER_LOGGING_THRESHOLD
```
public static final DurationConfigParam TRANSFER_LOGGING_THRESHOLD
```
    Used to log an info message when a commit log record exceeds this time interval from the time it was created, to the time it was written out to the network.
  - REPLAY_LOGGING_THRESHOLD
```
public static final DurationConfigParam REPLAY_LOGGING_THRESHOLD
```
    Used to log an info message when the time taken to replay a single log entry at a replica exceeds this threshold.
  - COMMIT_TO_NETWORK
```
public static final BooleanConfigParam COMMIT_TO_NETWORK
```
    Changes the notion of an ack. When set to true, a replica is considered to have acknowledged a commit as soon as the feeder has written the commit record to the network. That is, it does not wait for the replica to actually acknowledge the commit via a return message. This permits the master to operate in a more async manner relative to the replica provide for higher throughput. This config parameter is internal.

```
public static final DurationConfigParam PRE_HEARTBEAT_TIMEOUT
```
  - TXN_ROLLBACK_LIMIT

```
    Internal parameter used by the Arbiter.
  - SUBSCRIBER_USE
```

```
    Internal parameter used by network backups. If true, the node is used to support network backups and operates in read only mode, with various daemons disabled. TODO: would be nice to combine ARBITER_USE, SUBSCRIBER_USE and this into one concept.
  - NETWORKBACKUP_MAX_LAG
```
public static final IntConfigParam NETWORKBACKUP_MAX_LAG
```
    Internal parameter used by network backups. See 'Algorithm' in NetworkRestore. Is currently 50k, which represents less than 1s of replay time.
  - PRESERVE_RECORD_VERSION
```
public static final BooleanConfigParam PRESERVE_RECORD_VERSION
```
    Internal parameter to preserve record version (VLSN). Is immutable forever, i.e., it may not be changed after the environment has been created. It has the following impacts: . The VLSN is stored with the LN in the Btree and is available via the CursorImpl API. . The VLSN is included when migrating an LN during log cleaning. FUTURE: Expose this in ReplicationConfig and improve doc if we make record versions part of the public API.
  - CACHE_RECORD_VERSION
```
public static final BooleanConfigParam CACHE_RECORD_VERSION
```
    Whether to cache the VLSN in the BIN after the LN has been stripped by eviction, unless caching is explicitly disabled using the CACHE_RECORD_VERSION setting. This setting has no impact if PRESERVE_RECORD_VERSION is not also enabled. FUTURE: Expose this in ReplicationConfig and improve doc if we make record versions part of the public API.
