ORACLE RAC 11G 更改 /etc/hosts文件

）Can I change the public hostname in my Oracle Database 10g Cluster using Oracle Clusterware? Hostname changes are not supported in Oracle Clusterware (CRS), unless you want to perform a deletenode followed by a new addnode operation. The hostname is used to store among other things the flag files and Oracle Clusterware stack will not start if hostname is changed. （2）Does the hostname have to match the public name or can it be anything else? When there is no vendor clusterware, only Oracle Clusterware, then the public node name must match the host name. When vendor clusterware is present, it determines the public node names, and the installer doesn‘t present an opportunity to change them. So, when you have a choice, always choose the hostname. From： Metalink Note 220970.1 RAC Frequently Asked Questions:

（1）. RAC 环境一旦安装好后， 主机名就不能修改，除非先删除节点，修改Hostname， 在添加节点。

（2）. 主机名必须和public 名一致。这一点在安装文档中有特别强调。

由于之前的安装失误，将/etc/hosts文件配置成如下格式

#管理网段
30.11.3.178  rappdb1
30.11.3.179  rappdb2
#public IP
30.2.21.161  rappdb1-pub
30.2.21.163  rappdb2-pub

30.2.21.162  rappdb1-vip
30.2.21.163  rappdb2-vip

172.2.21.101  rappdb1-priv
172.2.21.102  rappdb2-priv

当安装完成后，监听中发现监听的是 管理IP（30.11.3.178）和VIP（30.2.21.162），正常应该是监听PublicIP和VIP。一般不建议直接修改hosts文件。

修复操作如下：

一、先卸载CRS
在非最后一个节点运行

/oracle/asm/crs/install/rootcrs.pl -verbose -deconfig -force

二、修改主机名 （本案例不涉及修改主机名）
smitty tcpip修改主机名
第一节点：dbrac1修改为dbrac100
第一节点：dbrac2修改为dbrac200

三、修改/etc/hosts

#管理网段
#30.11.3.178  rappdb1
#30.11.3.179  rappdb2
#public IP
30.2.21.161  rappdb1
30.2.21.163  rappdb2

30.2.21.162  rappdb1-vip
30.2.21.163  rappdb2-vip

172.2.21.101  rappdb1-priv
172.2.21.102  rappdb2-priv

 

四、修改11g grid的参数文件
修改$ORACLE_HOME/crs/install/crsconfig_params中相关部分：

ORACLE_HOME=/oracle/asm
ORACLE_BASE=/oracle/grid
OLD_CRS_HOME=

JREDIR=/oracle/asm/jdk/jre/
JLIBDIR=/oracle/asm/jlib

VNDR_CLUSTER=false

############### OCR constants
# GPNPCONFIGDIR is handled differently in dev (T_HAS_WORK for all)
# GPNPGCONFIGDIR in dev expands to T_HAS_WORK_GLOBAL
GPNPCONFIGDIR=$ORACLE_HOME
GPNPGCONFIGDIR=$ORACLE_HOME
OCRLOC=
OLRLOC=
OCRID=
CLUSTER_GUID=

CLSCFG_MISSCOUNT=

#### IPD/OS
CRFHOME="/oracle/asm"

注：10g RAC的参数配置文件： $ORA_CRS_HOME/install/rootconfig

五、在各个节点依次运行root.sh脚本
节点1运行root.sh
另外一个节点运行root.sh

六、注册信息
1.grid用户asmca命令加载ASMVG1
2.oracle用户注册集群信息
./srvctl add database -d racdb -o /oracle/db/product/11.2
./srvctl add instance -d racdb -i racdb1 -n dbrac100     
./srvctl add instance -d racdb -i racdb2 -n dbrac200
root用户
./srvctl add scan -n  dbrac-scan -S 8.8.6.0/255.255.255.0

3.grid用户netca注册监听

七、完成检查状态
$ crs_stat -t
Name           Type           Target    State     Host
