Orastress!的作者是Geoff Ingram,也就是我们前面介绍的orabm的作者,他曾经为Oracle工作数年,是High Performance Oracle" (ISBN: 0471224367)一书的作者.
该书现在你可以在本站下载.
关于该工具的官方网页在这里可以找到:
http://www.linxcel.co.uk/orabm/index.html
Orastress!你可以在原网站下载,或选择本地下载.
该工具不是开源的,缺省的只能使用一个session测试,你可以从作者那里申请临时Key,通过以下页面我们可以获得7天的无功能限制使用版:
http://www.linxcel.co.uk/7505/10218_trialkey_orastress!.html
Orastress!需要在windows上运行,你需要安装Oracle客户端.
收到Key以后，注册方式如下:
C:\\orabm>orastress!
Serial: D5F8-C0A0
After receiving the key, install as follows by entering the Name and Key into the dialog box that displays when you run:
C:\\orabm>orastress! register

Orastress!需要的数据和orabm类似,你可以参考Orabm的安装方式.
具体安装步骤如下:
# |
Operation |
Command |
1 |
create the ORABM user (assumes TOOLS tablespace, TEMP temporary tablespace) |
sqlplus system/pwd @orabm_user |
2 |
create the tables |
sqlplus system/pwd @orabm_tab |
3 |
load the data |
$ orabmload Warehouses n |
4 |
create the indexes |
sqlplus system/pwd @orabm_ind |
5 |
analyze the tables and indexes |
sqlplus system/pwd @orabm_analyze |
6 |
Ensure ORABM can run the DBMS_LOCK package |
As SYS run:
GRANT EXECUTE ON DBMS_LOCK TO ORABM |
注意:这里构建的如果是10个Warehouses的数据,那么大约需要1G的空间.
这里我建议对单节点数据库分别采用1,2,3,5,10个Warehouses进行1,2,4,6,10个并发的50000个事务的测试.
对于多节点RAC建议采用1,2,3,5,10个Warehouses进行1,3,4,7,10个并发的50000个事务的测试.
这一部分安装日志可以参考:安装日志
得到测试数据以后,还需要运行如下脚本:
sqlplus orabm/orabm@<your-TNS-alias> @orastress_tab.sql
sqlplus orabm/orabm@<your-TNS-alias> @orastress.plh
sqlplus orabm/orabm@<your-TNS-alias> @orastress.plb
日志参考:windows日志
命令行执行方式如下:
orastress! –s sess-iterations-list –t transacts-per-sess –c tns-alias-list –m mode [ -s batchsize]
这里需要如下参数:
-s 指定session数量
-t 指定每个session执行的事物数量.
-c 指定联结串
-m 指定运行模式.包括Read OLTP INS DIO
-s 指定对于INS或DIO模式下提交批量,缺省是10000里
Note: 如果 Orastress! 对单个Warehouse运行在read模式，那么代码执行和orabm相同.
对于四种运行模式说明如下:
READ:Runs the identical read-only workload as Orabm to stress CPU and memory.
OLTP:Uses all five TPC-C transactions: New-Order, Order-Status, Payment, Stock-Level and Delivery, in order to generate a mixed-transaction (SQL INSERT/UPDATE/DELETE) OLTP workload which stresses CPU, memory, and I/O.
INS:Runs an I/O intensive SQL INSERT workload by copying rows into the ITEM_INS table from the TPC-C ITEM table.
DIO:Runs an I/O intensive direct-path INSERT workload by copying rows into the ITEM_DIO table from the TPC-C ITEM table.
以下是一些运行举例:
Example 1:
orastress! –s 1 –t 50000 –c inst1.world –m oltp
Run one iteration - comprising 50000 transactions in 1 session - against inst1.world.
进行一组测试,通过一个session,包含50000个事务,对inst1.world数据库进行测试.
Example 2:
orastress! –s 2 –t 50000 –c inst1.world,inst2.world –m oltp
Run one iteration comprising 2 concurrent sessions of 50000 transactions on each of inst1.world,inst2.world giving a total of 4 concurrent sessions.The location of the instances specified by inst1.world,inst2.world is entirely down to the user. They could be:
运行一组测试，对两个数据库(inst1.world,inst2.world)各发出两个并发session，每个session运行50000个事务，这两个数据库可以是:
·2 instances of a RAC cluster
·different non RAC instances on the same server
·different non RAC instances on different servers (e.g. one on Linux, one on Solaris)
Example 3:
orastress! –s 1,2,4 –t 50000 –c inst1,inst2,inst3,inst4 –m read
Run 3 iterations each of 50000 transactions on each of four instances: inst1, inst2, inst3 and inst4, where the number of concurrent sessions in each iteration is:
运行3组测试，分别以1，2，4个并发session对四个实例，各执行50000个事务:
1st iteration: 1 concurrent session on each instance, giving 4 sessions total
2nd iteration: 2 concurrent sessions on each instance, giving 8 sessions total
3rd iteration: 4 concurrent sessions on each instance, giving 16 sessions
Output is very similar to Orabm, showing the transactions per second for each session in each iteration and the transaction split between the five TPC-C transactions for OLTP mode:
输出结果和orabm非常类似,具体参考:

在这里简单说明一下:
对于Benchmark测试来说,最重要的是标准,如果大家有统一的模型及标准,那么测试数据也就有了意义,否则以不同的并发、数据进行各不相同的测试是不具有太大意义的.
标准、比较、参考，这对于测试来说是最重要的.
