redhat linux 5.4 rac 修改主机名
0.配置信息
A.cluster安装用户是grid，设置 ORACLE_HOME=/u01/app/11.2.0/grid
B.RAC安装用户是oracle，设置 ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
C.VBox4.2.12+OEL6.4i386+Oracle11gR203+2节点Rac
1. 两个节点ora和orb，/etc/hosts的配置如下
192.168.11.101 ora
192.168.11.102 ora-vip
192.168.88.100 ora-priv
192.168.11.104 orb
192.168.11.105 orb-vip
192.168.88.101 orb-priv
192.168.11.103 ora-scan
2.CRS状态

2.现在要把两个节点的主机名改为rac1和rac2，方法是：删除2节点，改2节点主机名，加2节点进入crs，删除1节点，改1节点主机名，加1节点进入crs
3.删除2节点
A.检查2节点是否是active和Unpinned ，如果是pinned的，用crsctl unpin css
olsnodes -s -t
ora Active Unpinned
orb Active Unpinned
B. root用户在2节点 GRID_HOME 上执行
/u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force

L.加节点2到CRS
1.节点2上设置grid用户对等性
/u01/app/11.2.0/grid/deinstall/sshUserSetup.sh -user grid -hosts rac1 rac2 -noPromptPassphrase
2.节点2上grid用户，检查节点1是否满足
cluvfy stage -pre nodeadd -n rac1 -fixup -fixupdir /tmp -verbose
修改 $ORACLE_HOME/oui/bin/addNode.sh
M.加节点1到CRS
$ORACLE_HOME/oui/bin/addNode.sh "CLUSTER_NEW_NODES={rac1}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac1-vip}"
按照提示在1节点上用root执行：/u01/app/11.2.0/grid/root.sh
N.
##在旧节点名称上删除实例
srvctl remove instance -d orcl -i orcl1 -f -y
##加实例到新节点
srvctl add instance -d orcl -i orcl1 -n rac1 -f
##开始实例在新节点
srvctl start instance -d orcl -i orcl1
##查看数据库在节点上的状态
srvctl status database -d orcl
Instance orcl1 is running on node rac1
Instance orcl2 is running on node rac2
O. 发现两节点ASM实例名被修改为+ASM3和+ASM4
