Berkeley DB

Db.set_q_extentsize

						import com.sleepycat.db.*;
						public void set_q_extentsize(int extentsize)
						throws DbException;
					

Description

Set the size of the extents used to hold pages in a Queue database, specified as a number of pages. Each extent is created as a separate physical file. If no extent size is set, the default behavior is to create only a single underlying database file.

For information on tuning the extent size, see “Selecting an Extent Size.”

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

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

Errors

• EINVAL An invalid flag value or parameter was specified.
