Oracle RAC万能集群测试大全 支持11g/12c/18c/19c版本
为了方便阅读,请横屏观看代码部分
一、Oracle RAC集群测试背景
某中大型制造业公司,由于要新上项目,建设了一套业务系统-ERP系统,这套系统的数据库环境是Oracle RAC(RHEL Linux7+Oracle11gR2 RAC)架构 。
这套ERP系统的RAC集群数据库在上线之前,我们需要对RAC集群做一些功能测试,这个测试方法适用于Oracle11g/12c,也适用于Oracle18c/19c。
二、Oracle RAC集群的介绍
在测试之前,介绍一下Oracle RAC是什么:Oracle 真正应用集群技术(Oracle Real Application Cluster )是Oracle 9i及以后版本,Oracle 9i之前叫OPS集群。Oracle RAC主要支持Oracle9i、10g、11g、12c版本(18c,19c)。在Oracle RAC环境下,Oracle集群提供了集群软件和存储管理软件,集群软件CRS/GRID,存储管理软件ASM(自动存储管理),多个节点共享一份数据。
ORACLE RAC架构如下:
其中Oracle RAC在物理架构上,硬件设备主要包括如下部分:
服务器、共享存储设备(共享存储,光纤交换机,HBA卡,光纤线)、网络设备(网络交换机,光纤交换机,网线)
1)服务器
我们称这个服务器为“数据库服务器”,“数据库主机”,在RAC的术语中我们又称其为“节点”,服务器的配置应该相同,cpu,内存等。
2)网络设备
每台服务器上至少两块物理网卡,分别用于主机间私有通信和对外公用通信,也可以有多快网卡,进行网卡绑定,实现网卡的冗余。
私有通信的网卡叫private NIC,对应的IP为private IP。
公用通信的网卡叫public NIC,对应的IP为public IP。
3)共享存储设备
共享存储是整个RAC架构中的核心
每台服务器至少一块/两块HBA卡,用于共享存储的连接。
可以用光纤线直连存储,也可以通过光纤交换机,我们建议使用光纤交换机。
RAC是一个典型的“多实例,单数据库”架构,被所有节点共享,并行访问。
数据库数据文件,控制文件,参数文件,联机重做日志文件,甚至归档日志文件都放在共享存储上,并保证可以被所有节点同时访问。IO性能要求比较高,一般用光纤线连接。
另外Oracle RAC还有两种集群模式:
Oracle RAC 同时具备HA(High Availiablity) 、LB(LoadBalance)。
1)Failover(故障转移):
它指集群中任何一个节点的故障都不会影响用户的使用,连接到故障节点的用户会被自动转移到健康节点,从用户感受而言, 是感觉不到这种切换。
2)LoadBalance(负载均衡):
就是把负载平均的分配到集群中的各个节点,从而提高整体的吞吐能力。

针对测试列表中的第1点:客户端连接到数据库(RAC负载均衡测试)
Oracle 客户端的tnsnames.ora模式如下:只需要配置scan对应的name或ip地址即可,如下所示:
fgerpdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = www.fgedu.net.cn)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = fgerpdb)
)
)
最终Oracle RAC的测试效果如下:
针对测试列表中的第12点:客户端连接到数据库(RAC透明切换测试),客户端tnsnames.ora配置
fgerpdbtaf=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = www.fgedu.net.cn)(PORT = 1521))
(LOAD_BALANCE = YES)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = fgerpdb)
(FAILOVER_MODE =
(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5)
)
)
)
tnsping fgerpdbtaf 测试连通性
连通ok后,再用第12点的方式测试透明故障切换

2.停止数据库上的所有asm磁盘组和启动数据库上的所有磁盘组Srvctl stop database -d fgedu –o immediate
Srvctl start database -d fgedu
3.停止对应节点上的listener和启动对应节点上的listenerSrvctl stop asm –g crs
Srvctl stop asm –g dgsystem
Srvctl stop asm –g fgedudata1
Srvctl stop asm –g dgrecover
Srvctl start asm –g crs
Srvctl start asm –g dgsystem
Srvctl start asm –g fgedudata1
Srvctl start asm –g dgrecover
4.停止scan_listener和启动scan_listenerSrvctl stop listener -n fgerp61
Srvctl stop listener -n fgerp62
Srvctl start listener -n fgerp61
Srvctl start listener -n fgerp62
5.停止scan和启动scanSrvctl stop scan_listener
Srvctl start scan_listener
6.停止对应节点上的资源和启动对应节点上的资源Srvctl stop scan
Srvctl start scan
7.停止crs和启动crsSrvctl stop nodeapps -n fgerp62
Srvctl stop nodeapps -n fgerp61
Srvctl start nodeapps -n fgerp62
Srvctl start nodeapps -n fgerp61
停止crs
crsctl stop crs
Crsctl stop crs的方式能把所有grid进程都关闭掉
8.检查crs资源状态启动crs
crsctl start crs
9、用asmcmd工具管理asm磁盘组crsctl status resource -t
crs_stat –t
查看磁盘组容量
asmcmd lsdg
如果大家已经有一套Oracle RAC集群环境了,即可按照上面的过程来测试。
