tpc-ds99 工具使用

安装部署 tpc-ds-99 工具

解压文件

unzip tpc-ds-tool.zip

进入目录

cd v2.3.0/tools

拷贝Makefile文件

cp Makefile.suite Makefile

源码包缺少一个tokenizer.c 文件,作者从老版本的tpc-ds 包中找到放进去了,后附tokenizer.c 源码

编译可执行文件

make

创建临时目录

mkdir tmp

生成测试数据,测试数据总量为 1GB,生成的数据存放在tmp 目录下

./dsdgen -scale 1 -dir ./tmp

修改 sql 生成模版

vi ../query_templates/oracle.tpl

增加两个define 内容

define _BEGIN = "-- start query " + [_QUERY] + " in stream " + [_STREAM] + " using template " + [_TEMPLATE] + " and seed " + [_SEED];
define _END = "-- end query " + [_QUERY] + " in stream " + [_STREAM] + " using template " + [_TEMPLATE];

生成查询sql

./dsqgen -input ../query_templates/templates.lst -directory ../query_templates -dialect oracle 1

建立sql 临时目录

mkdir sql

将sql 文件拷贝到 sql 目录下

mv *.sql sql/
