New File Locking

The latest version of InfinityDB includes an option for InfinitydDB.open() and InfinityDB.create() that provides Java 1.4 nio native file locking. These options are recommended for all future development in order to prevent sharing of InfinityDB files by multiple processes.

The nio native file locks solve a long-standing problem for any application that needs to prevent inter-process concurrent access to file data. Simple solutions that have been tried in the past, such as using a separate lock file, have virtually all failed in some circumstances, although it has been reported that a certain technique using File.rename() actually does work. If you are using a custom scheme, please try to switch to the new system.

There is no change to the existing behavior of any InfinityDB API. If you are using InfinityDB in a J2ME environment, or anywhere else that does not allow Java 1.4, such as in memory-constrained devices, the nio locking is automatically bypassed.
