Berkeley DB

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 four-byte values, the set value may not be larger than the maximum unsigned four-byte value. By default, or if the value is set to 0, a size of 10MB is used. The size of the log file must be at least four times the size of the in-memory log buffer (see DbEnv.set_lg_bsize).

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.
