    import com.sleepycat.db.*;

    public int log_register(Db dbp, String name)
    	throws DbException;

# Description

The DbEnv.log_register method registers a file name with the specified Berkeley DB environment's log manager. The log manager records all file name mappings at each checkpoint so that a recovery process can identify the file to which a record in the log refers.

The dbp argument should be a reference to the Db object being registered. The name argument should be a file name appropriate for opening the file in the environment, during recovery.

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

# Errors

The DbEnv.log_register 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.

The DbEnv.log_register 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.log_register method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
