Modes of operation

The modes of operation determine how the probe stores and reads recovery data. This affects how the probe behaves on startup.

You can run the probe in one of the following modes:

  • Recovery - When the probe suddenly disconnects, information about the incomplete reading of the log file is stored in the recovery file as recovery data. On startup, the probe uses the recovery data and continues to read events created since it disconnected. To run the probe in the Recovery mode, specify the recovery file in the RecoveryFile property, and set the ReplayFile and CleanStart properties to 0.
    Note: If a recovery file is not present when the probe starts, the probe creates the recovery file with the name specified by the RecoveryFile property. If the RecoveryFile property is not specified, the default recovery file is used. Where more than one probe is being used, a different recovery file should be specified for each probe.
  • Cleanstart - The probe ignores the recovery file and reads the log file for events created after the probe started. To run the probe in Cleanstart mode, set the CleanStart property to 1 and set the ReplayFile property to 0.
  • Replay - The probe ignores the recovery file and starts reading events from the beginning of the log file, and then terminates. To run the probe in replay mode, set the ReplayFile property to 1 and set the CleanStart property to 0.
    Note: If you set both the CleanStart property and the ReplayFile property to 1, the probe replays the log file from the start and then continues to read the log file as new events are received.
