Berkeley DB: Db
Db

import com.sleepycat.db.*;
public class Db extends Object

Db(DbEnv dbenv, int flags)
throws DbException;

Description
This manual page describes the specific details of the Db class,
which is the center of access method activity.
If no dbenv value is specified, the database is standalone; that
is, it is not part of any Berkeley DB environment.
If a dbenv value is specified, the database is created within
the specified Berkeley DB environment. The database access methods
automatically make calls to the other subsystems in Berkeley DB based on the
enclosing environment. For example, if the environment has been
configured to use locking, the access methods will automatically acquire
the correct locks when reading and writing pages of the database.
The flags value must be set to 0 or by bitwise inclusively OR'ing together one or
more of the following values:
- Db.DB_XA_CREATE
- Instead of creating a standalone database, create a database intended to
be accessed via applications running under a X/Open conformant Transaction
Manager. The database will be opened in the environment specified by the
OPENINFO parameter of the GROUPS section of the ubbconfig file. See the
XA Resource Manager chapter in the
Reference Guide for more information.
