    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 log manager and returns a file identification number.

This file identification number should be used in all subsequent log messages that refer to operations on the file. The log manager records all file name to file identification number mappings at each checkpoint so that a recovery process can identify the file to which a record in the log refers.

The dbp parameter should be a reference to a Db object.

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

# Errors

If a fatal error occurs in Berkeley DB, the DbEnv.log_register method will fail and throw a DbRunRecoveryException, at which point all subsequent database calls will fail in the same way.

In addition, 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.

In addition, the DbEnv.log_register method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
