import com.sleepycat.db.*;public void set_lg_regionmax(int lg_regionmax) throws DbException;
Set the size of the underlying logging subsystem region, in bytes. By default, or if the value is set to 0, the base region size is 60KB. The log region is used to store filenames, and so may need to be increased in size if a large number of files will be opened and registered with the specified Berkeley DB environment's log manager.
The DbEnv.set_lg_regionmax interface may be used only to configure Berkeley DB before the DbEnv.open interface is called.
The DbEnv.set_lg_regionmax method throws an exception that encapsulates a non-zero error value on failure.
The database environment's log region 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_regionmax", 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.
The DbEnv.set_lg_regionmax method may fail and throw an exception encapsulating a non-zero error for the following conditions:
Called after DbEnv.open was called.
The DbEnv.set_lg_regionmax 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.set_lg_regionmax method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
