public void set_lk_conflicts(byte[][] conflicts) throws DbException;


Set the locking conflicts matrix. A non-0 value for the array element indicates that requested_mode and held_mode conflict:


The not-granted mode must be represented by 0.

If DbEnv.set_lk_conflicts is never called, a standard conflicts array is used; see Standard Lock Modes for more information.

The DbEnv.set_lk_conflicts method configures a database environment, not only operations performed using the specified DbEnv handle.

The DbEnv.set_lk_conflicts interface may not be called after the interface is called. If the database environment already exists when is called, the information specified to DbEnv.set_lk_conflicts will be ignored.

The DbEnv.set_lk_conflicts method throws an exception that encapsulates a non-zero error value on failure.


The DbEnv.set_lk_conflicts method may fail and throw an exception encapsulating a non-zero error for the following conditions:

An invalid flag value or parameter was specified.

Called after was called.

No memory was available to copy the conflicts array.

The DbEnv.set_lk_conflicts method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv.set_lk_conflicts method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
