1、概述
TPC是一系列事务处理和数据库基准测试的规范。其中TPC-C是针对OLTP的基准测试模型，一方面可以衡量数据库的性能，另一方面可以衡量硬件性价比，也是广泛应用并关注的一种测试模型。TPC-C通过TPM去衡量性价比，即每分钟的执行事务量。
本文介绍TPC-C之BenchmarkSQL对GaussDB T单机数据库进行性能压测。
对于分布式集群下的BenchmarkSQL测试，GaussDB T需要做适配，因为分布式下创建表必须要指定分片键的，默认的脚本是不指定的。
2、 BenchmarkSQL性能测试
2.1 安装JDK
BenchmarkSQL工具要求JDK7以上。检查系统JDK版本：
# java -version openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode) #
2.2 安装依赖包
# yum -y install ant
2.3 上传BenchmarkSQL工具包并解压
这里使用benchmarksql-5.0.zip工具包。
# mkdir -p /software/benchmark/
# cd /software/benchmark/

drwxr-xr-x 6 root root 67 5月 26 2016 src
#
2.4 编译BenchmarkSQL
使用ANT编译BenchMark的包，需要用到BenchMark的build包，进入到BenchMark的目录，执行ant进行编译。
# cd /software/benchmark/benchmarksql-5.0/ # ant Buildfile: /software/benchmark/benchmarksql-5.0/build.xml init: [mkdir] Created dir: /software/benchmark/benchmarksql-5.0/build compile: [javac] Compiling 11 source files to /software/benchmark/benchmarksql-5.0/build dist: [mkdir] Created dir: /software/benchmark/benchmarksql-5.0/dist [jar] Building jar: /software/benchmark/benchmarksql-5.0/dist/BenchmarkSQL-5.0.jar BUILD SUCCESSFUL Total time: 4 seconds # ls -l 总用量 28 drwxr-xr-x 2 root root 4096 3月 10 13:52 build -rwxr-xr-x 1 root root 1130 5月 26 2016 build.xml drwxr-xr-x 2 root root 34 3月 10 13:52 dist drwxr-xr-x 3 root root 17 5月 26 2016 doc -rwxr-xr-x 1 root root 6376 5月 26 2016 HOW-TO-RUN.txt drwxr-xr-x 5 root root 129 5月 26 2016 lib -rwxr-xr-x 1 root root 5318 5月 26 2016 README.md drwxr-xr-x 7 root root 4096 5月 26 2016 run drwxr-xr-x 6 root root 67 5月 26 2016 src #
2.5 拷贝GaussDB T的JDBC驱动到lib目录
拷贝GaussDB T的JDBC驱动到BenchmarkSQL的lib目录，jdbc驱动在安装包GaussDB_T_1.0.2-CLIENT-JDBC.tar.gz里。
# cd /software/benchmark/benchmarksql-5.0/lib/
# ls -l

#
2.6 创建测试数据库用户并授权
Zsql连接数据库，创建测试用户并授权：
$ zsql omm/yhadmin_123@192.168.179.123:1888 -q
connected.
SQL> create user aps2 identified by aps2_123;
Succeed.
SQL> grant connect,resource to aps2;
Succeed.
SQL> exit
$
2.7 创建benchmark配置文件
在benchmarksql的run目录下，编辑测试的配置文件props.gaussdb。
# pwd
/software/benchmark/benchmarksql-5.0/run
# cp props.ora props.gaussdb
# vi props.gaussdb
db=oracle
driver=com.huawei.gauss.jdbc.ZenithDriver
conn=jdbc:zenith:@192.168.179.123:1888
user=aps2
password=aps2_123
warehouses=10
loadWorkers=4
terminals=10
//To run specified transactions per terminal- runMins must equal zero
runTxnsPerTerminal=0
//To run for specified minutes- runTxnsPerTerminal must equal zero
runMins=5
//Number of total transactions per minute
limitTxnsPerMin=300
//Set to true to run in 4.x compatible mode. Set to false to use the
//entire configured database evenly.
terminalWarehouseFixed=true
//The following five values must add up to 100
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
#
参数说明：
配置文件中，db直接填写oracle即可，驱动driver为com.huawei.gauss.jdbc.ZenithDriver，连接串conn为jdbc:zenith:@IP:端口，这里配置连接数据库的IP地址和端口，user为连接数据库的用户名aps2，password为用户密码aps2_123。
warehouse数据仓库，表示markbench生成的数据表中数据量的大小。BenchmarkSQL数据库每个warehouse大小大概是100MB，如果该参数设置为10，那整个数据库的大小大概在1000MB。建议将数据库的大小设置为服务器物理内存的2-5倍，如果服务器内存为16GB，那么warehouse设置建议在328～819之间。
terminals 是指client的并发连接数，建议设置为服务器CPU总线程数的2-6倍。如果服务器为双核16线程（单核8线程），那么建议配置在32～96之间。
runTxnsPerTerminal是每分钟的执行事务数，runtime限制了执行的时间。配置这两个参数的时候，如果runTxnsPerTerminal的不为0的话，那么runtime的值必须为0。反之，如果配置runtime的话，如果runtime不为0，则runTxnsPerTerminal一定要等于0。
limitTxnsPerMin=300 是限制每分钟总共执行的事务数，0是无限制。
2.8 初始化测试数据
进入benchmarksql的run目录下，运行./runDatabaseBuild.sh props.gaussdb脚本，初始化测试数据。
