	string Filename,
	string DatabaseName,
	SecondaryDatabaseConfig cfg

Type: System..::.String
The name of an underlying file that will be used to back the database.
Type: System..::.String
This parameter allows applications to have multiple databases in a single file. Although no DatabaseName needs to be specified, it is an error to attempt to open a second database in a file that was not initially created using a database name.
Type: BerkeleyDB..::.SecondaryDatabaseConfig
The database's configuration

Return Value

A new, open database object


If Filename is null and DatabaseName is non-null, the database can be opened by other threads of control and will be replicated to client sites in any replication group.

If AutoCommit is set, the operation will be implicitly transaction protected. Note that transactionally protected operations on a datbase object requires the object itself be transactionally protected during its open.
