备注

Every database has a Primary filegroup, and if you define instance database properties in the instance configuration file (ICF), you must have a Primary filegroup. You can have additional filegroups to group additional data files together for administrative, data allocation, and placement purposes. For more information about files and filegroups, see 了解文件和文件组.

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

示例

This example shows how to define the primary filegroup for the instance database:

<NamedFileGroup>
    <FileGroupName>Primary</FileGroupName>
    <FileSpec>
        <LogicalName>PrimaryFG</LogicalName>
        <FileName>%BaseDirectoryPath%\Primary.mdf</FileName>
        <Size>10MB</Size>
        <MaxSize>20MB</MaxSize>
        <GrowthIncrement>20%</GrowthIncrement>
    </FileSpec>
</NamedFileGroup>
