1. 创建管理数据仓库
在SQL Server 2008中有很多组件可以进行性能数据收集。为了设定收集数据的类型以及收集计划,数据收集器需要使用管理数据仓库。管理数据仓库也是一个关系型,但在创建该时很多默认设置需要进行修改,在我们后面的实验中将深入讨论。理想状态下,管理数据仓库最好和生产环境的数据库位于不同的上,以便实现更好的性能。
数据收集所针对的目标是SQL Server 的实例,每一个实例都有收集组与之相对应,其中收集组指特定的收集类型,例如磁盘和查询统计。数据收集依靠SQL Server Agent 或SSIS按照计划来执行,因此作业和计划都会存储在msdb数据库中。管理数据仓库的角色就是存储数据、一些聚合值、以及针对系统分析而生成的历史信息。
在第一个练习当中,我们将安装管理数据仓库:
1. 打开 SQL Server Management Studio.
依次点击Start | All Programs | Microsoft SQL Server 2008 | SQL Server Management Studio
2. SQL Server Management Studio 打开以后,在Connect to Server 对话框中,输入如下信息,然后点击Connect:
Server type: Database Engine
Server name: CHICAGO\CONFIGSERVER
Authentication: Windows Authentication
3. 在Object Explorer中,依次展开Management 和Data Collection.
4. 右键点击Data Collection 然后点击Configure Management Data Warehouse.
5. 点击Next.
6. 在配置Management Data Warehouse 时需要做两件事:创建SQL Server 数据库用于存储收集上来的数据计数;指定缓存文件夹,数据在加载到管理数据仓库之前会临时被缓存在这里。对于收集操作比较频繁的数据集,所收集的数据会在本地缓存,然后再批量导入到管理数据仓库,从而降低了网络负载并提高了数据收集时的性能。
7. 在Configure Management Data Warehouse Wizard 页面中,选择Create or upgrade a management data warehouse 然后点击Next.
8. 服务器名称会自动填写
注意:你必须有足够的权限,以便在服务器中创建管理数据仓库。更多详细信息,请参考SQL Server 2008 Books Online 中的CREATE DATABASE (Transact-SQL) 以及Data Collector Security 部分
9. 点击New新建管理数据仓库。
按照下图所示进行设置。即将数据库名称设置为ManagementDW:
10. 点击 OK 接收默认设置并创建ManagementDW 数据库。注意:即便在后面的步骤中取消向导,该数据库也将在该步骤中创建
11. 点击Next.
