Oceanbase TPCC性能压测

李真旭 2020-06-10

Oceanbase的性能应该是非常强劲的，但是闻名不如见面；还是自己测一下，眼见为实更靠谱。我这里测试参考了ob解决方案架构师的文章https://zhuanlan.zhihu.com/p/112894850，其在github上提供了benchmarkSQL，直接下载编辑一下即可。主要修改一下props.ob配置文件即可，如下：

[root@td1 run]# cat props.ob
db=oracle
driver=com.alipay.oceanbase.obproxy.mysql.jdbc.Driver
conn=jdbc:oceanbase://127.1:2883/roger?useUnicode=true&characterEncoding=utf-8
user=roger@oboracle#obdemo
password=roger
warehouses=2
loadWorkers=2
terminals=10
//To run specified transactions per terminal- runMins must equal zero
runTxnsPerTerminal=0
//To run for specified minutes- runTxnsPerTerminal must equal zero
runMins=10
//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=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
[root@td1 run]# cat props.ob

不调整参数，可能load会报错，类似如下：

[admin@td1 run]$  ./runSQL.sh props.ob ./sql.oceanbase/indexCreates.sql

create  index bmsql_oorder_idx1
on  bmsql_oorder (o_w_id, o_d_id, o_carrier_id, o_id) local;
[admin@td1 run]$

这里你可以直接执行shell脚本，也可以直接在obclient中执行创建index语句。

因为是虚拟机，资源配置非常低，因此第一次测试各方面参数都设置的很低。

将终端调整到最大值10后，性能有大幅提升：

由于我这里是Oracle租户，通过监控系统发现cpu idle较高，因此我再次调整了租户资源限制：

obclient>  ALTER resource unit sys_unit_config max_cpu=3, min_cpu=2.5;
Query OK, 0 rows affected (0.01 sec)
obclient>  alter resource unit my_unit_config max_cpu=3, min_cpu=1;
Query OK, 0 rows affected (0.01 sec)
obclient>  ALTER resource unit sys_unit_config max_cpu=3, min_cpu=2.5;
Query OK, 0 rows affected (0.01 sec)
obclient>  alter resource unit my_unit_config max_cpu=3, min_cpu=1;
Query OK, 0 rows affected (0.01 sec)

然后重新初始化2个仓,再次进行测试，性能更进一步。

大家可以看到tpm基本上到16000了。看上去还是不错。我这里的Oracle租户cpu max才3，内存最大为10gb.

在进行tpcc测试时，可以查询相关视图，监控db的性能状态，ob的oracle兼容模式也提供了类似oracle的v$session_wait 等待事件接口，这里我们来看看。
