public class Db extends Object
Db(DbEnv dbenv, int flags)
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, i.e.,
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, then 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.
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.
