# DbEnv.set_lg_max

`

###

    import com.sleepycat.db.*;

    public void set_lg_max(int lg_max)
    	throws DbException;

# Description

Set the maximum size of a single file in the log, in bytes. Because DbLsn file offsets are unsigned 4-byte values, the set value may not be larger than the maximum unsigned 4-byte value. By default, or if the value is set to 0, a size of 10MB is used.

See Log File Limits for more information.

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

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

The database environment's log file size may also be set using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "set_lg_max", one or more whitespace characters, and the size in bytes. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after DbEnv.open was called.

  The specified log file size was too large.
