to conform to ANSI
database isolation terminology.
This ensures the stability of the current data item read by the cursor but permits data read by this cursor to be modified or deleted prior to the commit of the transaction.
public static final CursorConfig WRITECURSOR
The underlying Berkeley DB database environment must have been configured as a Concurrent Data Store environment.
