RAC 修改 ASM实例名 的步骤

在DBCA 创建ASM实例时，会生成几个ASM实例，如+ASM1和+ASM2。 一般来说，安装好之后，是不需要修改ASM实例名的，但是一些特殊情况，还是需要修改的，就像我之前说的：

RAC 中 ASM 实例名 与 节点的对应关系

http://blog.csdn.net/tianlesoftware/archive/2011/03/23/6272244.aspx

这个名称看上去就不一致，不是很直观。

在这篇Blog里，就是测试RAC下，ASM实例名的修改。 将2个节点的实例做下倒换。 也可以换成其他名字。 RAC 实例名的修改，放到下一篇。

一. ASM 实例基本信

节点rac1， ASM 实例名：+ASM2.

节点rac2，ASM 实例名：+ASM1。

有点怪异。 把2个ASM实例给换下。操作过程需要宕机。 所以在系统上线之前就把这些东西配置好。 上线之后就不要在乱动了。 稳定第一。

二. 具体操作步骤：

2.1 在任一个节点上更新OCR

步骤如下

（1）Stop all the db instances that store their data in the asm instance you will be doing the maintenance:
srvctl stop db -d <db name>

（2）Stop the asm instance:
srvctl stop asm -n <node name>
（3）Remove asm dependencies for the db instance and unregister asm from the OCR:
srvctl modify inst -d <db name> -i <db instance name> -r

srvctl remove asm -n <node name>

[oracle@rac1 u01]$

2.2 在所有节点上更新/etc/oratab 文件

Location of oratab on some platforms:
* For AIX, HP-UX, or Linux: /etc/oratab
* For Solaris: /var/opt/oracle/oratab

节点1：

[oracle@rac1 u01]$ cat /etc/oratab | grep -v ^#

+ASM2:/u01/app/oracle/product/10.2.0/db_1:N

rac:/u01/app/oracle/product/10.2.0/db_1:N

修改之后：

[oracle@rac1 u01]$ cat /etc/oratab | grep -v ^#

+ASM1:/u01/app/oracle/product/10.2.0/db_1:N

rac:/u01/app/oracle/product/10.2.0/db_1:N

节点2：

[oracle@rac2 ~]$ cat /etc/oratab |grep -v '^#'

+ASM1:/u01/app/oracle/product/10.2.0/db_1:N

rac:/u01/app/oracle/product/10.2.0/db_1:N

修改之后：

[oracle@rac2 ~]$ cat /etc/oratab |grep -v '^#'

+ASM2:/u01/app/oracle/product/10.2.0/db_1:N

rac:/u01/app/oracle/product/10.2.0/db_1:N

2.3 在所有节点上修改init 文件和orapw 文件

节点1：

[oracle@rac1 u01]$ cd $ORACLE_HOME/dbs

[oracle@rac1 dbs]$ ls

ab_+ASM2.dat hc_rac2.dat initdw.ora initrac2.ora orapwrac2

hc_+ASM2.dat init+ASM2.ora init.ora orapw+ASM2

[oracle@rac1 dbs]$ mv init+ASM2.ora init+ASM1.ora

[oracle@rac1 dbs]$ mv orapw+ASM2 orapw+ASM1

[oracle@rac1 dbs]$ ls

ab_+ASM2.dat hc_rac2.dat initdw.ora initrac2.ora orapwrac2

hc_+ASM2.dat init+ASM1.ora init.ora orapw+ASM1

节点2：

[oracle@rac2 ~]$ cd $ORACLE_HOME/dbs

[oracle@rac2 dbs]$ ls

ab_+ASM1.dat hc_rac1.dat initdw.ora initrac1.ora orapwrac1

hc_+ASM1.dat init+ASM1.ora init.ora orapw+ASM1

[oracle@rac2 dbs]$ mv init+ASM1.ora init+ASM2.ora

[oracle@rac2 dbs]$ mv orapw+ASM1 orapw+ASM2

[oracle@rac2 dbs]$ ls

ab_+ASM1.dat hc_rac1.dat initdw.ora initrac1.ora orapwrac1

hc_+ASM1.dat init+ASM2.ora init.ora orapw+ASM2

2.4 修改ASM pfile 参数

（1）If using a pfile:
Replace any references to the old asm instance names with the new asm names.
Example:
+ASM1.instance_number=1 -- change to --> +ASMADC1.instance_number=1

（2）If using an spfile:
Connect to the ASM instance, and use SQL commands.
Example on node1 to remove the references to +ASM1:
SQL> alter system reset instance_number sid='+ASM1' scope=spfile;

Example on node1 to set the new value:
SQL> alter system set instance_number=1 sid='+ASMADC1' scope=spfile;

我配置RAC时使用的是pfile，所以需要在所有节点上都修改pfile参数。

节点1：

[oracle@rac1 dbs]$ cat init+ASM1.ora |grep instance

instance_type=asm

+ASM2.instance_number=2

+ASM1.instance_number=1

修改之后：

[oracle@rac1 dbs]$ cat init+ASM1.ora |grep instance

instance_type=asm

+ASM1.instance_number=2

+ASM2.instance_number=1

节点2：

[oracle@rac2 dbs]$ cat init+ASM2.ora |grep instance

instance_type=asm

+ASM2.instance_number=2

+ASM1.instance_number=1

修改之后：

[oracle@rac2 dbs]$ cat init+ASM2.ora |grep instance

instance_type=asm

+ASM1.instance_number=2

+ASM2.instance_number=1

2.5 清除相关的目录

If using 10g, on each node remove any directories and files for the older ASM instance under: $ORACLE_BASE/admin
If using 11g, on each node remove any directories and files for the older ASM instance under: $ORACLE_BASE/diag/

　

You may choose to back these first for historical purposes only.

[oracle@rac1 dbs]$ cd $ORACLE_BASE/admin

[oracle@rac1 admin]$ ls

+ASM rac

这一步，我没有做，历史文件不影响，只是看上去比较乱。可以把相关目录（+ASM）下文件全部清空。

2.6 在任意一个节点更新OCR

Example to register the new ASM instance that will run in node1:
srvctl add asm -nadc1-i+ASMADC1-o /c1/app/oracle/product/11.1.0.6/asm_1

Where adc1 is node_name, +ASMADC1 is the new ASM instance name, and the value given to -o is the ORACLE_HOME for the asm instance.

Register each database instance that stores their data in ASM, with the new ASM instance name.

Example:
srvctl modify inst -d <db name> -i <instance name> -s +ASMADC<n>

具体操作：

[oracle@rac1 admin]$ srvctl add asm -n rac1 -i +ASM1 -o /u01/app/oracle/product/10.2.0/db_1

[oracle@rac1 admin]$ srvctl add asm -n rac2 -i +ASM2 -o /u01/app/oracle/product/10.2.0/db_1

[oracle@rac1 dbs]$ srvctl modify inst -d rac -i rac2 -s +ASM1

[oracle@rac1 dbs]$ srvctl modify inst -d rac -i rac1 -s +ASM2

注意： 不要被我这里的顺序误导，正常情况下，就是：

srvctl modify inst -d rac -i rac1 -s +ASM1

我在建RAC的时候，因为安装顺序的问题，到时ASM实例反了。 开始我是按下面命令创建的：

[oracle@rac1 admin]$ srvctl modify inst -d rac -i rac1 -s +ASM1

PRKS-1019 : Cannot create CRS dependency between database instance "rac1" configured on node "rac2" and ASM instance "+ASM1" configured on node "rac1"

但是报错了，后来才发现，我的RAC1 实例，是在rac2 节点上，这里应该就是我们主节点。 由此也可以看出，ORACLE 会默认把安装Clusterware的节点作为节点1. 并且写入OCR中。

我们这个实验只是测试一下ASM实例的修改，下次在测试下实例名修改的问题。 开始错了一步，后面的麻烦事真多啊。

有点小兴奋，实例名和节点名总算对上号了。 不过实例名和节点还是反的。 杯具啊。 下次遇到这种问题，我会重新安装CRS来解决。

至此，RAC的ASM实例名，已经修改成功了。 但是RAC 实例名和节点名还是反过来的。 明天在做个测试，把RAC的实例名也修改一下。

也就是为了好奇。 顺便做下测试。不过记住了一点，安装RAC的时候，从第一个节点开始安装。 不然后面会比较麻烦。

有空还是希望能研究透CRS，看看CRS 是如何控制这个节点顺序的。
