#### Parameters

Filename
  Type: System..::.String
  The name of an underlying file used to back the database.

cfg
  Type: BerkeleyDB..::.SecondaryDatabaseConfig
  The database's configuration

txn
  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.

# Remarks

If AutoCommit is set, the operation is implicitly transaction protected. Transactionally protected operations on a database object requires the object itself be transactionally protected during its open.
