DbEnv.set_lg_bsize

APIRef

import com.sleepycat.db.*;

public void set_lg_bsize(int lg_bsize) throws DbException;

Description

Set the size of the in-memory log buffer, in bytes.

Log information is stored in-memory until the storage space fills up or transaction commit forces the information to be flushed to stable storage. In the presence of long-running transactions or transactions producing large amounts of data, larger buffer sizes can increase throughput.

By default, or if the value is set to 0, a size of 32K is used.

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

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

Errors

EINVAL
An invalid flag value or parameter was specified.

Called after DbEnv.open was called.
