DM数据库性能测试实践

标签：root   loader   code   查看   parallel   一个   extent   chm   文件   

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
