SQL Replay使用指南

一. SQL Replay简介

SQL Replay它是SQL Server Profiler中的一个trace模板，它将收集数据库服务器中必要的事件trace，用于在相同或不同的服务器上回放。通过改进模板脚本，我们可以更好的生成自定义的回放trace。这类trace主要可以帮助我们分析语句在同一台服务器的不同数据库对象上运行的性能(如索引、主键等)，检测这些数据库对象变更前后的性能差异；也可以分析语句在不同数据库服务器的相同数据库对象上的运行性能，检测服务器不同硬件等配置的性能差异。

二. SQL Replay脚本

DECLARE @rc int
DECLARE @TraceID int
DECLARE @maxfilesize bigint
DECLARE @DateTime datetime
DECLARE @filecount INT
DECLARE @path VARCHAR(100)
DECLARE @WHO VARCHAR(200)

----------------------------------修改以下参数----------------------------------

SET @maxfilesize = 300                --文件最大的大小，单位：M
SET @filecount=5                --文件个数
SET @DateTime = '2013-05-08 10:00:00.000'    --trace截止日期
SET @path='E:\BIFLT_Trace_Replay'        --trace文件保存路径
SET @WHO='%你的用户名%'                --过滤用户

----------------------------------修改以上参数----------------------------------
SET @path=REPLACE(@path,'.TRC','')
exec @rc = sp_trace_create @TraceID output, 2, @path, @maxfilesize , @Datetime,@filecount
if (@rc != 0) goto error

-- Set the events
