import com.sleepycat.db.*;
public void set_lk_conflicts(byte[][] conflicts)
throws DbException;
public void set_lk_conflicts(byte[][] conflicts) throws DbException;
Description
Set the locking conflicts matrix. A non-0 value for the array element indicates that requested_mode and held_mode conflict:
conflicts[requested_mode][held_mode]
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 interface may be used only 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
The DbEnv.set_lk_conflicts method may fail and throw an exception encapsulating a non-zero error for the following conditions:
- 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.
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.
