Public NotInheritable Class InstanceDatabaseLogFile

Notes

Each instance database can has 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 instance database after creating the instance, use the Microsoft SQL Server tools, such as SQL Server Management Studio.

Exemple

The following examples show how to define a log file for an instance database:

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);

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)
