今天小编分享的是关于DM数据库性能测试报告,可能大家对DM数据库并不陌生,或者从来没有了解过DM数据库。但是不用担心,今天小编会以最简单的描述来讲解聚类算法的原理。
一.环境说明
1.1 测试机环境:
说明:
测试机环境为一般主机即可,要求不高
1.2 虚拟机环境:
二.测试拓扑
说明:
1.性能测试为不同主机测试即:测试机与被测系统不再一个机器上面
2.测试机为一般主机即可
3.测试机与物理机之间的网络最低为千兆网络
注:当前是华为鲲鹏服务器。同样适用于长城服务器
三.测试步骤
3.1 创建测试用户与表
在数据库中输入:
create tablespace "TPCC" datafile 'TPCC.dbf' size 10000 autoextend on;
create user benchmarksql identified by 123456789 default tablespace "TPCC";
grant dba to benchmarksql;
3.2 执行工具创建表
[root@benchmarksql run]# ./runSQL.sh props.dm sqlTableCreates
3.3 执行工具加载测试数据,注意xxx要与配置文件中的warehouses的值保持
[root@benchmarksql run]# ./runLoader.sh props.dm numWarehouses 100
3.4 执行工具创建数据库索引
[root@benchmarksql run]# ./runSQL.sh props.dm sqlIndexCreates
3.5 扩库和日志
alter tablespace "ROLL" resize datafile 'ROLL.DBF' to 5000;
alter database resize logfile 'DAMENG01.log' to 20000;
alter database resize logfile 'DAMENG02.log' to 20000;
SP_SET_TAB_FAST_POOL_FLAG('BENCHMARKSQL', 'ITEM', 1);
SP_SET_TAB_FAST_POOL_FLAG('BENCHMARKSQL', 'WAREHOUSE', 1);
SP_SET_TAB_FAST_POOL_FLAG('BENCHMARKSQL', 'DISTRICT', 1);
3.6 设置参数,要重启数据库服务
MAX_OS_MEMORY = 100
MEMORY_POOL = 1000
BUFFER = 100000
BUFFER_POOLS = 101
FAST_POOL_PAGES = 90000
FAST_ROLL_PAGES = 80000
RECYCLE = 8
MULTI_PAGE_GET_NUM = 64MAX_BUFFER = 100000
VM_MEM_HEAP = 0
WORKER_THREADS = 24
WORK_THRD_STACK_SIZE = 512
CKPT_RLOG_SIZE = 0
CKPT_INTERVAL = 3600
CKPT_DIRTY_PAGES = 0
FORCE_FLUSH_PAGES = 0
IO_THR_GROUPS =12
CHECK_DB_IS_ACTIVE = 0
BDTA_SIZE = 20
ENABLE_SPACELIMIT_CHECK = 0
RLOG_PARALLEL_ENABLE = 1
RLOG_RESERVE_SIZE = 0
SESS_CHECK_INTERVAL = 30
FAST_RELEASE_SLOCK = 0
NOWAIT_WHEN_UNIQUE_CONFLICT = 1
UNDO_EXTENT_NUM = 32
UNDO_RETENTION = 1
MAX_SESSIONS = 1000
SUBQ_EXP_CVT_FLAG = 0
PURGE_DEL_OPT = 1
ENABLE_FREQROOTS = 2
CACHE_POOL_SIZE = 100
DICT_BUF_SIZE = 20
ENABLE_MONITOR = 0
3.7 将数据加载到内存
select count() from "BENCHMARKSQL"."CUSTOMER" union all
select count() from "BENCHMARKSQL"."DISTRICT" union all
select count() from "BENCHMARKSQL"."ITEM" union all
select count() from "BENCHMARKSQL"."NEW_ORDER" union all
select count() from "BENCHMARKSQL"."OORDER" union all
select count() from "BENCHMARKSQL"."ORDER_LINE" union all
select count() from "BENCHMARKSQL"."STOCK" union all
select count() from "BENCHMARKSQL"."WAREHOUSE" union all
select count(*) from "BENCHMARKSQL"."HISTORY" union all
select count("C_PAYMENT_CNT") from "BENCHMARKSQL"."CUSTOMER";
3.8 执行工具开始执行测试
[root@benchmarksql run]# ./runBenchmark.sh props.dm
3.9 查看结果
[root@benchmarksql run]# cat ./log/benchmarksql.log
