Osservazioni

Use the InstanceDatabaseOptions class to configure the default filegroup and collation for the instance database.

Specifying instance database properties is optional. For more information about default values, see Definizione del database dell'istanza.

If you want to alter the instance database after creating the instance, use the Microsoft SQL Server tools, such as SQL Server Management Studio.

Esempio

The following examples show how to define data files, log files, and database properties for an instance database:

// Define instance database properties
// Create the InstanceDatabaseOptions object
InstanceDatabaseOptions idb = 
    new InstanceDatabaseOptions(myInstance, "MyInstDB");

// Define and add a filegroup
InstanceDatabaseFileGroup idb_fg = 
    new InstanceDatabaseFileGroup(idb, "PRIMARY");
idb.InstanceDatabaseFileGroups.Add(idb_fg);

// Define and add a data file
InstanceDatabaseFile idb_file1 = 
    new InstanceDatabaseFile(idb_fg, "MyInst_PrimaryFile1");
idb_file1.FileName = @"C:\NS\Full\MyInst_PrimaryFile1.mdf";
idb_file1.InitialSize = "5MB";
idb_file1.MaxSize = "15MB";
idb_file1.GrowthIncrement = "10%";
idb_fg.InstanceDatabaseFiles.Add(idb_file1);

// Define and add a log file
InstanceDatabaseLogFile idb_log = 
    new InstanceDatabaseLogFile(idb, "MyInst_LogFile1");
idb_log.FileName = @"C:\NS\Full\MyInst_LogFile1.ldf";
idb_log.InitialSize = "3MB";
idb_log.MaxSize = "10MB";
idb_log.GrowthIncrement = "10%";
idb.InstanceDatabaseLogFiles.Add(idb_log);

// Define database options
idb.CollationName = "Latin1_General_CS_AS";
idb.DefaultFileGroup = "PRIMARY";

// Assign options to Instance.InstanceDatabaseOptions property
myInstance.InstanceDatabaseOptions = idb;

' Create the InstanceDatabaseOptions object
Dim idb As InstanceDatabaseOptions = _
    New InstanceDatabaseOptions(myInstance, "MyInstDB")

' Define and add a filegroup
Dim idb_fg As InstanceDatabaseFileGroup = _
    New InstanceDatabaseFileGroup(idb, "PRIMARY")
idb.InstanceDatabaseFileGroups.Add(idb_fg)

' Define and add a data file
Dim idb_file1 As InstanceDatabaseFile = _
    New InstanceDatabaseFile(idb_fg, "MyInst_PrimaryFile1")
idb_file1.FileName = "C:\NS\Full\MyInst_PrimaryFile1.mdf"
idb_file1.InitialSize = "5MB"
idb_file1.MaxSize = "15MB"
idb_file1.GrowthIncrement = "10%"
idb_fg.InstanceDatabaseFiles.Add(idb_file1)

' Define and add a log file
Dim idb_log As InstanceDatabaseLogFile = _
    New InstanceDatabaseLogFile(idb, "MyInst_LogFile1")
idb_log.FileName = "C:\NS\Full\MyInst_LogFile1.ldf"
idb_log.InitialSize = "3MB"
idb_log.MaxSize = "10MB"
idb_log.GrowthIncrement = "10%"
idb.InstanceDatabaseLogFiles.Add(idb_log)

' Define database options
idb.CollationName = "Latin1_General_CS_AS"
idb.DefaultFileGroup = "PRIMARY"

' Assign options to Instance.InstanceDatabaseOptions property.
myInstance.InstanceDatabaseOptions = idb

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
