###

    import com.sleepycat.db.*;

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

# Description

Set the locking conflicts matrix. A non-0 value for the array element:

>     lk_conflicts[requested_mode][held_mode]

indicates that requested_mode and held_mode conflict. The not-granted mode must be represented by 0.

If no lk_conflicts value is specified, the conflicts array db_rw_conflicts is used; see Standard Lock Modes for a description of that array.

The DbEnv.set_lk_conflicts interface may only be used to configure Berkeley DB before the DbEnv.open interface is called.

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

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after DbEnv.open was called.

ENOMEM
  No memory was available to copy the conflicts array.
