os: centos 7.4
db: postgresql 9.6
上一篇 blog 介绍了安装好了 BenchmarkSQL，现在开始压测配置。
仔细阅读下 benchmarksql-5.0.zip 解压后 HOW-TO-RUN.txt 、 README.md 这两个文件，里面有详细的步骤。
创建数据库
$ psql
psql (9.6.11)
Type "help" for help.
postgres=#
postgres=# create user benchmarksql superuser password 'benchmarksql';
postgres=# create database benchmarksql owner benchmarksql;
postgres=# \q
$ psql -h 127.0.0.1 -U benchmarksql benchmarksql
psql (9.6.11)
Type "help" for help.
benchmarksql=#
benchmarksql=# create schema benchmarksql;
benchmarksql=# \dn+
List of schemas
Name | Owner | Access privileges | Description
--------------+--------------+------------------------------+------------------------
benchmarksql | benchmarksql | |
public | postgres | postgres=UC/postgres +| standard public schema
| | =UC/postgres |
(2 rows)
编辑 benchmarksql 连接配置和压测配置
初始化10个仓库,测试时长3分钟,不限事务数，本地虚拟机，性能不够。
参数很好理解，看看就明白
$ cd ~/benchmarksql-5.0/run/
$ cp props.pg props.pg.bak
$ vi props.pg
db=postgres
db=postgres
driver=org.postgresql.Driver
conn=jdbc:postgresql://127.0.0.1:5432/benchmarksql
user=benchmarksql
password=benchmarksql
warehouses=10
loadWorkers=2
terminals=2
//To run specified transactions per terminal- runMins must equal zero
runTxnsPerTerminal=0
//To run for specified minutes- runTxnsPerTerminal must equal zero
runMins=3
//Number of total transactions per minute
limitTxnsPerMin=0
//Set to true to run in 4.x compatible mode. Set to false to use the
//entire configured database evenly.
terminalWarehouseFixed=false
//The following five values must add up to 100
//The default percentages of 45, 43, 4, 4 & 4 match the TPC-C spec
newOrderWeight=45
paymentWeight=43
orderStatusWeight=4
deliveryWeight=4
stockLevelWeight=4
// Directory name to create for collecting detailed result data.
// Comment this out to suppress.
resultDirectory=my_result_%tY-%tm-%td_%tH%tM%tS
osCollectorScript=./misc/os_collector_linux.py
osCollectorInterval=1
//osCollectorSSHAddr=user@dbhost
osCollectorDevices=net_eth0 blk_sda
创建表结构
$ cd ~/benchmarksql-5.0/run
$ ./runSQL.sh ./props.pg ./sql.common/tableCreates.sql
生成测试数据
$ mkdir ~/benchmarksql-csv
$ cd ~/benchmarksql-5.0/run
$ ./runLoader.sh ./props.pg fileLocation ~/benchmarksql-csv/
$ ls -l ~/benchmarksql-csv
total 714740
-rw-r--r-- 1 postgres postgres 62 Dec 6 12:03 config.csv
-rw-r--r-- 1 postgres postgres 20563737 Dec 6 12:03 cust-hist.csv
-rw-r--r-- 1 postgres postgres 173002967 Dec 6 12:03 customer.csv
-rw-r--r-- 1 postgres postgres 9496 Dec 6 12:03 district.csv
-rw-r--r-- 1 postgres postgres 7568445 Dec 6 12:03 item.csv
-rw-r--r-- 1 postgres postgres 828000 Dec 6 12:03 new-order.csv
-rw-r--r-- 1 postgres postgres 13461204 Dec 6 12:03 order.csv
-rw-r--r-- 1 postgres postgres 210432944 Dec 6 12:03 order-line.csv
-rw-r--r-- 1 postgres postgres 305998994 Dec 6 12:03 stock.csv
-rw-r--r-- 1 postgres postgres 889 Dec 6 12:03 warehouse.csv
导入数据
$ cd ~/benchmarksql-5.0/run
$ ln -s ~/benchmarksql-csv /tmp/csv
$ ./runSQL.sh ./props.pg ./sql.postgres/tableCopies.sql
$ ./runSQL.sh ./props.pg ./sql.common/indexCreates.sql
$ ./runSQL.sh ./props.pg ./sql.common/foreignKeys.sql
tableCopies.sql 是从/tmp/csv 导入数据的，所以要 ln -s
提示：可以运行 ./runDatabaseBuild.sh ./props.pg 一步完成 创建表、生成测试数据、导入数据。
tpc-c 压测以及性能指标
$ cd ~/benchmarksql-5.0/run
$ ./runBenchmark.sh ./props.pg
tpc-c 结果绘图
查看压测数据
$ cd ~/benchmarksql-5.0/run
$ tree ./my_result_2018-12-06_121705/
./my_result_2018-12-06_121705/
├── data
│ ├── blk_sda.csv
│ ├── result.csv
│ ├── runInfo.csv
│ └── sys_info.csv
└── run.properties
1 directory, 5 files
生成报告
$ cd ~/benchmarksql-5.0/run
$ ./generateGraphs.sh ./my_result_2018-12-06_121705/
$ ./generateReport.sh ./my_result_2018-12-06_121705/
重新压测
对发现的问题优化后，可以重新再压测。
$ cd ~/benchmarksql-5.0/run
$ ./runDatabaseDestroy.sh ./props.pg
$ ./runDatabaseBuild.sh ./props.pg
$ ./runBenchmark.sh ./props.pg
