步骤2: 修改SQL Server服务账号的权限 SQL Server的服务账户需要获得“通过权限”来启用瞬时文件初始化。这一过程涉及到Windows的安全设置。 首先,找出SQL Server服务的账户: 打开“服务”管理工具,找到SQL Server (MSSQLSERVER)服务。 右键单击服务,选择“属性”,然后切换到“登录”选项卡,查看“登录为”下的内容。
今天我想谈下SQL Server里的一个特别话题——即时文件初始化(Instant File Initialization)。对于你的SQL Server实例,如果你启用了即时文件初始化,在特定情况下,你会获得巨大的性能提升。即时文件初始化定义了当在数据文件里分配新的空间时,SQL Server引擎如何和Windows操作系统打交道。 问题缘由 在SQL Server默认配置...
Instant File Initialization (New File) Instead of incremental changes to the VDL, SQL Server uses the fast allocation capability of SetEndOfFile and then calls SetFileValidData with the same offset. All data prior the VDL is considered written (valid) by the Windows file syste...
In SQL Server, instant file initialization allows for faster execution of the previously mentioned file operations, since it reclaims used disk space without filling that space with zeros. Instead, disk content is overwritten as new data is written to the files. In Azure SQL...
它代表的是Windows操作系统的“Instant File Initialization”特性。意思就是在Windows操作系统下,文件在被创建的时候是否执行“zeroing out”任务,也就是把文件系统分配给某个文件的空间都通过写0来清楚原先的数据。开启了文件及时初始化后在Windows下我们删除一个文件其实并没有把磁盘上的数据清除,而是留到下一次这...

Instant file initialization and the transaction log Applies to:SQL Server 2022 (16.x) and later versions, and Azure SQL Database and Azure SQL Managed Instance. Historically, transaction log files couldn't be initialized instantaneously. However, starting with SQL Server 2022 (16.x) (all edi...
This is part 2 of my series on ‘Instant File Initialization’ and how that ‘brand name’ actually works under the covers. This post will take a look at what really happens when a database file is created and how the ‘Instant File Initialization’ opti
通过从命令提示符安装 SQL Server 的新实例,可以指定要安装的功能以及如何配置这些功能。 还可以指定与安装用户界面是进行静默交互、基本交互还是完全交互。若要通过命令提示符安装或配置 SQL Server 实例,请打开管理命令提示符,然后导航到 setup.exe 在 SQL Server 安装介质中所处的位置。 运行 setup.exe 命令,以及...
