corda.p2p.linkManager

Configuration schema for the P2P link manager.

• heartbeatEnabled - Deprecated (not used). Whether heartbeat messages should be sent or not between peers to detect unhealthy sessions.
  Default value: true

• heartbeatMessagePeriod - Deprecated (not used). The heartbeat message period in milliseconds.
  Default value: 2000
  Minimum value: 500

• maxMessageSize - The maximum message size in bytes.
  Default value: 1000000
  Minimum value: 1000

• maxReplayingMessages - The maximum number of replaying messages between two peers.
  Default value: 100
  Minimum value: 1

• numOfSessionsPerPeer - Deprecated (not used). The number of actively maintained sessions between two peers.
  • forMembers - The number of actively maintained sessions between two peers if both peers are members. The default value of 2 is recommended because the chance of both sessions failing on the same link manager is relatively low. If high-availability is critical, R3 recommends deploying multiple link manager instances instead.
    Default value: 2
    Minimum value: 1
  • forMgm - The number of actively maintained sessions between two peers if one of them is an MGM. Communication between an MGM and a member is not considered critical and so the default value of 1 is recommended to improve performance.
    Default value: 1
    Minimum value: 1

• replayAlgorithm - The algorithm used to schedule messages for replay.
  • constant - Replay messages at a constant rate.
    • messageReplayPeriod - The message replay period in milliseconds.
      Default value: 2000
      Minimum value: 500
  • exponentialBackoff - Replay messages with capped exponential backoff.
    • baseReplayPeriod - The message replay period base in milliseconds.
      Default value: 2000
      Minimum value: 500
    • replayPeriodCutoff - The message replay period cutoff in milliseconds.
      Default value: 10000
      Minimum value: 500

• revocationCheck - The type of revocation check for the session certificate.
  • mode This must be set to one of the following values:
    • SOFT_FAIL - The revocation check will succeed if the revocation status cannot be determined under certain circumstances. See java.security.cert.PKIXRevocationChecker.Option.SOFT_FAIL java doc for more details.
    • HARD_FAIL - The opposite of SOFT_FAIL. This is the most rigorous check. Amongst other requirements, this check requires that the CRL checking URL is available on every level of certificate chain.
    • OFF - Disables the CRL check.
    Default value: SOFT_FAIL

• sessionRefreshThreshold - Deprecated (not used). The session refresh threshold in seconds. The default value is five days.
  Default value: 432000
  Maximum value: 432000

• sessionTimeout - The session timeout in milliseconds.
  Default value: 60000
  Minimum value: 500

• sessionsPerPeer - Deprecated (not used). The number of actively maintained sessions between two peers.
  Default value:
  Minimum value: 1
