[Oracle 11.2.0.3] Modify Hostname on GI (standalone server)
来源：互联网 发布：ubuntu vnc客户端 编辑：程序博客网 时间：2024/06/06 09:32
本文目的:
本文源自于Oracle 11.2.0.3 GI Standalone 数据迁移之后，由于GI管理方式下网络IP地址和主机名迁移之前无法变更【更改后CRS服务无法启动，
顾官方不提供也不推荐相关更改方法】。故编写此文记录如何在GI管理单实例的情况下更改主机名和[IP]， 整体更改过程：
- 更改主机名(CRS服务因此会无法启动)
- 停止GI (HAS)服务
- 使用roothas.pl 重新配置GI(HAS)（更改OCR中相关注册信息）
- 重新手动添加CRS资源（listener/asm/diskgroup/db）
1. 原有环境
1.1 主机名和IP
#hostname
#test1
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:50:56:89:61:70
inet addr:192.168.1.196 Bcast:10.64.37.255 Mask:255.255.255.128
inet6 addr: fe80::250:56ff:fe89:6170/64 Scope:Link

#more /etc/hosts
192.168.1.196 test1
2. 更改后环境
#hostname
#test2
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:50:56:89:61:70
inet addr:192.168.2.196 Bcast:10.64.37.255 Mask:255.255.255.128
……
#more /etc/hosts
……
192.168.2.196 test2
3. 更改过程
3.1 记录更改前CRS Resource 信息
【实验】故可以预先保存CRS Resource
#su – grid
grid@test1:~> pwd
grid@test1:~>/home/grid
grid@test1:~>mkdir test1
grid@test1:~> for x in `$GRID_HOME/bin/crsctl stat res | grep NAME\= | awk -F\= '{print $2}'`; do $GRID_HOME/bin/crsctl stat res $x -p > mytest/$x.txt ; done
grid@test1:~>cd test1
grid@test1:~>ls -al

3.2 Change hostname

#more /etc/hosts

3.3 Stop Has 并检查是否还存在has服务
【注意】如果还存在ohasd.bin reboot service则会出现3.5小节的错误
[root@test 1~]# /opt/app/oracle/product/11.2/grid/bin/crsctl stop has –f
[root@test 1~]#ps –ef|grep grid

3.4 以root用户执行roothas.pl 重新配置has
#id
#uid=0(root) gid=0(root) groups=0(root)
#cd /opt/app/oracle/product/11.2/grid/crs/install
test2:/opt/app/oracle/product/11.2/grid/crs/install#/u01/app/oracle/product/11.2.0/grid/crs/install/roothas.pl -h
Option hahome requires an argument
Usage:
roothas.pl [-verbose] [-upgrade | -patch]
[-paramfile <parameter-file>] [-deconfig] [-force]
[-unlock [-hahome <path to Oracle Restart home>]]
Options:
-verbose Run this script in verbose mode
-upgrade Oracle HA is being upgraded from previous version
-patch Oracle HA is being upgraded to a patch version
-paramfile Complete path of file specifying HA parameter values
-deconfig To deconfigure Oracle Restart
-force To deconfigure Oracle Restart when configuration is in a good condition
-unlock Unlock Oracle Restart home
-hahome Complete path of Oracle HA home
If neither -upgrade nor -patch is supplied, a new install is performed
To see the full manpage for this program, execute:
perldoc roothas.pl
# ./roothas.pl -verbose -deconfig -force
Using configuration parameter file: ./crsconfig_params
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Stop failed, or completed with errors.
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Delete failed, or completed with errors.
CRS-4544: Unable to connect to OHAS
CRS-4000: Command Stop failed, or completed with errors.
Successfully deconfigured Oracle Restart stack
3.5 使用roothas.pl重新注册主机名等相关信息到OCR和inittab
# pwd
#/opt/app/oracle/product/11.2/grid/crs/install
#./roothas.pl -verbose
Using configuration parameter file: ./crsconfig_params
LOCAL ADD MODE
Creating OCR keys for user 'grid', privgrp 'oinstall'..
Operation successful.
Failed to write the checkpoint:'ROOTCRS_OLR' with status:SUCCESS.Error code is 256
LOCAL ONLY MODE
Successfully accumulated necessary OCR keys.
Creating OCR keys for user 'root', privgrp 'root'..
Operation successful.
CRS-4664: Node test1 successfully pinned.
Failed to write the checkpoint:'ROOTCRS_OHASD' with status:SUCCESS.Error code is 256
Adding Clusterware entries to inittab
Failed to write the checkpoint:'ROOTCRS_INITRES' with status:SUCCESS.Error code is 256
【注意】此时主机名理应更改过了，应为test2，说明在注册过程中 还有没有读取到/etc/hosts中的test2，
而是从crs某些服务直接取得的hostname，故检查此时是否还存在运行的HAS服务：
# ps -aef | grep grid
grid 5283 1 2 15:29 ? 00:00:01 /opt/app/oracle/product/11.2/grid/bin/ohasd.bin reboot
grid 5460 1 0 15:30 ? 00:00:00 /opt/app/oracle/product/11.2/grid/bin/oraagent.bin
grid 5474 1 0 15:30 ? 00:00:00 /opt/app/oracle/product/11.2/grid/bin/evmd.bin
grid 5507 5474 0 15:30 ? 00:00:00 /opt/app/oracle/product/11.2/grid/bin/evmlogger.bin -o /opt/app/oracle/product/11.2/grid/evm/log/evmlogger.info-l/opt/app/oracle/product/11.2/grid/evm/log/evmlogger.log
root 5521 4366 0 15:30 pts/0 00:00:00 grep grid
【注意】在3.3小节中停止HAS后，需要检查该服务是否未停干净，如果没有，执行3.6操作
3.6 KILL has service
【注意】杀完后需要重新检查，直到ohasd.bin reboot"消失

3.8 检查crs信息
test2:/opt/app/oracle/product/11.2/grid/bin # ./crsctl stat res | grep NAME\=
NAME=ora.cssd
NAME=ora.diskmon
NAME=ora.evmd
NAME=ora.ons
3.9 添加CRSResource
- 添加监听
grid@test2:~> srvctl add listener -l LISTENER -p "TCP:1521" –o /opt/app/oracle/product/11.2/grid/
grid@test2:~> srvctl start listener
grid@test2:~> srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): test2
grid@test2:~> crs_stat -t
