oracleasm-2.6.18-238.el5xen-2.0.5-1.el5

3.9修改redhat-release文件

/etc/redhat-release

RedHatEnterpriseLinuxServerrelease4(Tikanga)

3.10划分存储并创建卷组

3.10.1为磁盘创建物理卷标

先以root身份在第一个节点上执行：

[root@oradb1~]#pvcreate/dev/mapper/mpath1

[root@oradb1~]#pvcreate/dev/mapper/mpath2

[root@oradb1~]#pvcreate/dev/mapper/mpath3

[root@oradb1~]#pvcreate/dev/mapper/mpath4

3.10.2划分存储分区

以root身份在第一个节点上执行fdisk进行存储磁盘分区：

[root@oradb1~]#fdisk/dev/mapper/mpath1

为第一块存储创建3个分区，前两个分别为2GB大小，第三个为250G大小，输入：

【n、p、1、回车、+2G、n、p、2、回车、+2G、n、p、3、回车、回车、w】

[root@oradb1~]#fdisk/dev/mapper/mpath2

为第二块存储创建1个分区，为整个磁盘大小【输入n、p、1、回车、回车、w】

[root@oradb1~]#fdisk/dev/mapper/mpath3

为第三块存储创建1个分区，为整个磁盘大小【输入n、p、1、回车、回车、w】

[root@oradb1~]#fdisk/dev/mapper/mpath4

为第四块存储创建1个分区，为整个磁盘大小【输入n、p、1、回车、回车、w】

创建oravg卷组

vgcreateoravg/dev/mapper/mpath1p3/dev/mapper/mpath2p1/dev/mapper/mpath3p1/dev/mapper/mpath4p1

创建完成后执行vgscan

[root@oradb1~]#vgscan

Readingallphysicalvolumes.Thismaytakeawhile...

Foundvolumegroup"oravg"usingmetadatatypelvm2

Foundvolumegroup"VolGroup00"usingmetadatatypelvm2

再执行vgdisplayoravg

[root@oradb1~]#vgdisplayoravg

摘要：单击Install。

当弹出ExecuteConfigurationscripts界面时，先将p4679769_10201_LINUX补丁进行安装，方法为将p4679769_10201_LINUX.zip中的clsfmt.bin文件以oracle身份上传至/oracle/product/10.2.0/crs_1/bin文件夹下【oradb1、oradb2都要做】，覆盖原有的clsfmt.bin；

修改/oracle/product/10.2.0/crs_1/bin/vipca文件：

找到如下内容：

Removethisworkaroundwhenthebug3937317isfixed

arch=`uname-m`

if["$arch"="i686"-o"$arch"="ia64"]

then

LD_ASSUME_KERNEL=2.4.19

执行配置脚本：以root用户身份按顺序执行以下脚本（一次执行一个）。在当前脚本完成后，再继续执行下一个脚本。

a)在oradb1上执行/oracle/oraInventory/orainstRoot.sh

b)在oradb2上执行/oracle/oraInventory/orainstRoot.sh

c)在oradb1上执行/oracle/product/10.2.0/crs_1/root.sh

d)在oradb2上执行/oracle/product/10.2.0/crs_1/root.sh

oradb2上的root.sh脚本会自动调用VIPCA，但会因为“Thegiveninterface(s),"eth0"isnotpublic.PublicinterfacesshouldbeusedtoconfigurevirtualIPs.”错误而失败。如果您的公共接口使用不可路由的IP地址(10.1.3.x)，则Oracle集群验证实用程序(CVU)将无法找到合适的公共接口。一种解决方法是手动运行VIPCA。

5了解OracleRAC数据库

5.1检查数据库集群运行状况
在任意节点上运行crs_stat–t命令：

[oracle@oradb1~]$crs_stat-t

NameTypeTargetStateHost

------------------------------------------------------------

ora....db2.onsapplicationONLINEONLINEoradb2

ora....db2.vipapplicationONLINEONLINEoradb2

检查Target和State状态，如果全部为“ONLINE”说明正常，否则状态为“OFFLINE”。

5.2数据库TNS
通过TNS连接数据库时，双机方式与单机方式TNS连接串有所不通，普通单机TNS如下，例如：

ORADB2=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=TCP)(HOST=oradb2-vip)(PORT=1521))

(CONNECT_DATA=

(SERVER=DEDICATED)

(SERVICE_NAME=oradb)

(INSTANCE_NAME=oradb2)

)

)

ORADB1=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=TCP)(HOST=oradb1-vip)(PORT=1521))

(CONNECT_DATA=

(SERVER=DEDICATED)

(SERVICE_NAME=oradb)

(INSTANCE_NAME=oradb1)

)

)

而双机方式连接串应为：

ORADBSRV=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=TCP)(HOST=oradb1-vip)(PORT=1521))

(ADDRESS=(PROTOCOL=TCP)(HOST=oradb2-vip)(PORT=1521))

(LOAD_BALANCE=yes)

(CONNECT_DATA=

(SERVER=DEDICATED)

(SERVICE_NAME=oradbsrv)

(FAILOVER_MODE=

(TYPE=SELECT)

(METHOD=BASIC)

(RETRIES=180)

(DELAY=5)

)

)

)

用户将以上连接串复制到$ORACLE_HOME/network/admin/tnsnames.ora文件中，即可通过TNS连接OracleRAC。

5.3检查Oracle集群件的状态
在节点1和节点2运行crsctlcheckcrs命令：

[oracle@oradb1~]$crsctlcheckcrs

CSSappearshealthy

CRSappearshealthy

EVMappearshealthy

[oracle@oradb2~]$crsctlcheckcrs

CSSappearshealthy

CRSappearshealthy

EVMappearshealthy

5.4列出Oracle实例
使用sqlplus客户端连接OracleRAC，执行以下SQL：

SQL>selectinstance_name,host_name,archiver,thread#,statusfromgv$instance;

6如何扩展表空间

1)哪些裸设备已经被使用，可以用户sql脚本（selectnamefromv$datafile）来查询得到；

2)参考查看/etc/sysconfig/rawdevices文件内容，即可得到哪个lv映射到了哪个raw设备。如“/dev/raw/raw3/dev/oravg/system”，表示oravg卷组中的system这个lv映射到了/dev/raw/raw3这个裸设备文件；分配表空间时，就参考这个文件中，哪些裸设备还未被使用，就可以将这些裸设备文件，分配给所需的表空间。

注：data开头的lv对应的裸设备可以被加入到表空间中，非data开头的lv不能使用，因为已经作为oracle安装时的默认初始文件已经使用了；lv名称中有tmp的是预留作为tmp表空间扩展使用的，其他都是作为主表空间扩展预留的；

3)对已有的表空间，如果发现空间满时，可以通过新增数据文件方式扩展表空间，方法如下：

lvs用来查看目前系统有哪些lv逻辑卷，当lv的属性为“-wi-a-”时，则该lv所对应的裸设备未被使用，可以做为扩展表空间的数据文件使用：

7如何新增表空间

创建表空间示例sql：

CREATETABLESPACEtbs_02

DATAFILE'diskb:tbs_f5.dat'SIZE500KREUSE

AUTOEXTENDONNEXT500KMAXSIZE100M;

这里tbs_02是表空间名称，“diskb:tbs_f5.dat”是数据文件路径，初始大小500k，自增长500k，最大100M，按需调整即可。注意的是，这里的“diskb:tbs_f5.dat”换成第6章节中确定的不在占用的“-wi-a-”状态的裸设备文件/dev/raw/raw[x]即可。

8如何使用扩充存储

如果因为存储空间不够，新增加了新的存储设备，则需经过如下几步，进行扩容，这里假设新增的存储路径为/dev/mapper/mpath9：

1)为存储分配pv，标记为LVM，命令为pvcreate，格式例如：

#pvcreate/dev/mapper/mpath9

2)将新存储增加到已有的vg中，命令为vgextend，格式如下：

#vgextendoravg/dev/mapper/mpath9

3)在oravg中，创建新的或扩展已有的lv，命令为：

①创建新的:

#lvcreate-L5G-nnew_lvoravg

②扩展已有的：

#lvextend–L+20M/dev/oravg/old_lv（扩充逻辑卷old_lv的大小）

记得在B机上，要激活刚新创建的lv，如果是扩展就不需要了。

#lvchange-ay/dev/oravg/new_lv

注：如果是新增的lv，继续新增裸设备映射

4)修改/etc/sysconfig/rawdevices文件，增加内容：

/dev/raw/raw99/dev/datavg/new_lv

5)变更裸设备主属：

chownoracle:dba/dev/raw/raw99

6)变更裸设备权限：

chmod660/dev/raw/raw99

7)接下来这个裸设备就可以作为数据文件，加入到表空间中了，方法参考第6章节。

9OracleRAC常见问题

9.1无法通过JDBCURL以负载均衡方式连接数据库
采用jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.3.9)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.3.11)(PORT=1521))(LOAD_BALANCE=yes)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=oradbsrv)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)(RETRIES=180)(DELAY=5))))连接串连接数据库时通常无法连接数据库。

解决方法：

以管理员账户连接数据库执行以下命令：

sql>altersystemsetlocal_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.3.9)(PORT=1521))'sid='oradb1';

sql>altersystemsetlocal_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.3.11)(PORT=1521))'sid='oradb2';
