18.4 How to manage NCP server setting locks?

  1. In Configuration > NCP, search or browse to select the server.

  2. In NCP > Server Environment drop-down, select NCP > Locks.

  3. You can manage the following options:

    • Cross-protocol locks

      Cross-protocol locks prevent the same file from being concurrently accessed for modifications from both CIFS and NCP client.

    • Oplock support level

      NCP opportunistic locking allows the client to cache file data for better performance. You can select anyone of the options from the drop-down.

      • Disable

      • Exclusive locks

      • Shared and exclusive locks

    • Lock range mask

      Allow applications to acquire a lock above the address (0x7fffffffffffffff) region.

    • Byte range lock spin time

      Specify the range between 0 and 5000 (milliseconds) to avoid lock collisions when the LockTimeOut is sent as 0 in a Byte Range Request from the client.

    • Log lock statistics

      When an NCP volume lock is held more than the configured time, the NCP server displays a message in the ncpserv.log file with the relevant details.

  4. Select and specify the required NCP server locks options and click Save.
