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 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. Configuration in the DB_CONFIG file silently overrules configuration done using the DbEnv.set_lg_max method.

Errors

EINVAL

An invalid flag value or parameter was specified.

Called after DbEnv.open was called.
