Defines an application database log file.

Namespace: Microsoft.SqlServer.Management.Nmo
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

Syntax

'Declaration
Public NotInheritable Class ApplicationDatabaseLogFile
    Inherits NamedSmoObject

public sealed class ApplicationDatabaseLogFile : NamedSmoObject

public ref class ApplicationDatabaseLogFile sealed : public NamedSmoObject

public final class ApplicationDatabaseLogFile extends NamedSmoObject

public final class ApplicationDatabaseLogFile extends NamedSmoObject

Remarks

Each application database can have one or more log files. You can define zero or more log files; if you do not define a log file, Notification Services uses Microsoft SQL Server default settings and creates a single log file that is 25 percent of the sum of the all the database's data files' sizes or 512 KB, whichever is larger.

For more information about defining log files, see CREATE DATABASE (Transact-SQL).

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

Example

The following examples show how to define a log file for the application database:

ApplicationDatabaseLogFile adb_log = 
    new ApplicationDatabaseLogFile(adb, "MyApp_LogFile1");
adb_log.FileName = @"C:\NS\Full\MyApp_LogFile1.ldf";
adb_log.InitialSize = "5MB";
adb_log.MaxSize = "20MB";
adb_log.GrowthIncrement = "10%";
adb.ApplicationDatabaseLogFiles.Add(adb_log);

Dim adb_log As ApplicationDatabaseLogFile = _
    New ApplicationDatabaseLogFile(adb, "MyApp_LogFile1")
adb_log.FileName = "C:\NS\Full\MyApp_LogFile1.ldf"
adb_log.InitialSize = "5MB"
adb_log.MaxSize = "20MB"
adb_log.GrowthIncrement = "10%"
adb.ApplicationDatabaseLogFiles.Add(adb_log)
