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 -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
建立sql 临时目录
mkdir sql
将sql 文件拷贝到 sql 目录下
mv *.sql sql/
