oracle9.2/Linux rac 动态加入新节点(3)

配置Oracle Cluster Manger

 

重新配置已存在的节点

l         修改rac1的Cluster Manger文件

(红色为加入的内容)

[oracle@rac1 admin]$ vi cmcfg.ora

ClusterName=Oracle Cluster Manager, version 9i

MissCount=210

PrivateNodeNames=rac2-priv rac1-priv rac3-priv

PublicNodeNames=rac2 rac1 rac3

ServicePort=9998

CmDiskFile=/dev/raw/raw1

KernelModuleName=hangcheck-timer

HostName=rac1-priv

l         修改rac2的Cluster Manger文件

[oracle@rac2 admin]$ vi cmcfg.ora

ClusterName=Oracle Cluster Manager, version 9i

MissCount=210

PrivateNodeNames=rac2-priv rac1-priv rac3-priv

PublicNodeNames=rac2 rac1 rac3

ServicePort=9998

CmDiskFile=/dev/raw/raw1

KernelModuleName=hangcheck-timer

HostName=rac2-priv

注：上述文件只要修改即可，的第三个节点相关启动时，它会自动重新配置。

3.2配置新节点

l         修改rac3的Cluster Manger文件

ClusterName=Oracle Cluster Manager, version 9i

MissCount=210

PrivateNodeNames=rac2-priv rac1-priv rac3-priv

PublicNodeNames=rac2 rac1 rac3

ServicePort=9998

CmDiskFile=/dev/raw/raw1

KernelModuleName=hangcheck-timer

HostName=rac3-priv

l         在rac3上启动Cluster Manger

[root@rac2 9.2]$ mkdir /var/opt/oracle

[root@rac2 9.2]$ vi /var/opt/oracle/srvConfig.loc

srvconfig_loc=/dev/raw/raw14

[root@rac2 9.2]$ chown -R oracle:dba /var/opt/oracle

[root@rac3 oracle]# chmod -R 755 /var/opt/oracle/srvConfig.loc

[root@rac3 ~]# . /home/oracle/.bash_profile

[root@rac3 ~]# /u01/oracle/product/9.2/oracm/bin/ocmstart.sh

[oracle@rac3 ~]$ ps -ef|grep ora

检查ocm日志

[oracle@rac2 log]$　tail –f /u01/oracle/product/9.2/oracm/log/cm.log

HandleUpdate(): SYNC(6) from node(0) completed {Mon Mar  3 18:12:28 2008 }^M

Successful reconfiguration,  3 active node(s) node 0 is the master, my node num is 0 (reconfig 7) {Mon Mar  3 18:12:29 2008 }^M

 

   这时可以启动gsd服务

[oracle@rac3 ~]$ gsdctl start

[oracle@rac3 ~]$ ps -ef|grep gsd
