Instantiate a new SecondaryDatabase object, open the database represented by Filename and associate the database with the primary index. The file specified by Filename must exist.

Namespace: BerkeleyDB
Assembly: libdb_dotnet62 (in libdb_dotnet62.dll) Version: 6.2.32.0

# Syntax

C#
    public static SecondaryDatabase Open(
    	string Filename,
    	string DatabaseName,
    	SecondaryDatabaseConfig cfg
    )

Visual Basic (Declaration)
    Public Shared Function Open ( _
    	Filename As String, _
    	DatabaseName As String, _
    	cfg As SecondaryDatabaseConfig _
    ) As SecondaryDatabase

Visual C++
    public:
    static SecondaryDatabase^ Open(
    	String^ Filename,
    	String^ DatabaseName,
    	SecondaryDatabaseConfig^ cfg
    )

#### Parameters

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

DatabaseName
  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.

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

#### Return Value

A new, open database object

# Remarks

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 is implicitly transaction protected. Transactionally protected operations on a database object requires the object itself be transactionally protected during its open.
