Type: System..::.String
The name of an underlying file that will be used to back the database.
Type: BerkeleyDB..::.SecondaryDatabaseConfig
The database's configuration
Type: BerkeleyDB..::.Transaction
If the operation is part of an application-specified transaction, txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.

A new, open database object


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.
