Note: For information on overriding default configuration settings, see Modify configuration settings.

Follow the procedure below to configure a timeout value for a process to obtain a lock on a table queue. By default, the timeout value is set to 300 milliseconds.

Note: Only adjust this value if the following message appears repeatedly in the oasErrLog.log file: Timed out trying to lock DataExport.<table name>.

To override the timeout value

  1. In the %DNADataRoot%\RealTime\config\Settings directory, either create or open the RealTime_DataExport.json file.

  2. In the DataExport section under RealTime, add a QueueLockTimeOutMs key with a value greater than 0:

    "QueueLockTimeOutMs": 400

    The following example shows a configuration file with a queue lock timeout value set to 400 milliseconds.

    {

    "RealTime": {

    "DataExport": {

    "QueueLockTimeOutMs": 400

    }

    }

    }

  3. Save the file.

  4. Restart the RealTime service.
