CHECKLOCK_FILE <YES/NO>
Available in version 13.0.3 onwards:
If YES (default), ctCHECKLOCK is enabled on all files.
If NO, ctCHECKLOCK is not enabled (which is the behavior before 13.0.3).
You can enable or disable this feature for individual files using CHECKLOCK_FILE.
Breaking Change: As of version 13.0.3, the server prevents a record from being updated if it is not locked. This has always been the intended behavior, but previous versions did not enforce it. Use AUTO_CHECKLOCK NO to revert to the previous behavior.
