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 a 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. Called after Db.open was called.
