oracle RAC新增和删除节点手册 - 图文(7)

1、在rac3执行

[root@rac2 ~]# /etc/init.d/oracleasm configure Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting without typing an answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle Default group to own the driver interface []: dba Start Oracle ASM library driver on boot (y/n) [n]: y Fix permissions of Oracle ASM disks on boot (y/n) [y]: y Writing Oracle ASM library driver configuration: [ OK ] Loading module \

Mounting ASMlib driver filesystem: [ OK ] Scanning system for ASM disks: [ OK ]

2、Rac3上也扫描和查看当前磁盘组：

[root@rac2 ~]# /etc/init.d/oracleasm scandisks Scanning system for ASM disks: [ OK ]

[root@rac2 ~]# /etc/init.d/oracleasm listdisks VOL1 VOL2

3.3 配置新节点上的CRS

在节点1上以图形界面登录，oracle用户登录，rac1上执行

[oracle@rac1 ~]$ cd $ORA_CRS_HOME/oui/bin 31

[oracle@rac1 bin]$ ./addNode.sh 打开如下安装界面

点”next”，在第一列输入新增节点主机名：rac3

查看日志信息 [oracle@rac1 ~]$ tail -f /u01/app/oracle/oraInventory/logs/addNodeActions2011-11-29_09-42-48PM.log INFO: /u01/app/oracle/product/10.2.0/crs_1/oui/bin/../bin/runInstaller -paramFile /u01/app/oracle/product/10.2.0/crs_1/oui/bin/../clusterparam.ini -silent -ignoreSysPrereqs -updateNodeList -noClusterEnabled ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs_1 CLUSTER_NODES=rac1,rac2,rac3 CRS=true \rac1 -logFilePath \ -timestamp 2011-11-29_09-42-48PM INFO: OUI-10234:Failed to copy the root script, /u01/app/oracle/oraInventory/orainstRoot.sh to the cluster nodes rac3. Please copy them manually to these nodes and execute the script [oracle@rac1 ~]$ scp /u01/app/oracle/oraInventory/orainstRoot.sh rac3:/u01/app/oracle/oraInventory/ 以上步骤不一定需要

运行相关脚本：

1、[root@rac3 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh

提示如下信息

Changing permissions of /u01/app/oracle/oraInventory to 770. Changing groupname of /u01/app/oracle/oraInventory to oinstall. The execution of the script is complete
