[Oracle 11.2.0.3] Modify Hostname on GI (standalone server)

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           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:25000682 errors:0 dropped:20244 overruns:0 frame:0           TX packets:15881315 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:7392294006 (7049.8 Mb)  TX bytes:6365551420 (6070.6 Mb) #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 drwxr-xr-x 2 grid oinstall  4096 Sep  9 10:09 . drwxr-x--- 3 grid oinstall 12288 Sep  9 10:08 .. -rw-r--r-- 1 grid oinstall   912 Sep  9 10:09 ora.asm.txt -rw-r--r-- 1 grid oinstall  1693 Sep  9 10:09 ora.orcl.db.txt -rw-r--r-- 1 grid oinstall  1407 Sep  9 10:09 ora.cssd.txt -rw-r--r-- 1 grid oinstall   760 Sep  9 10:09 ora.DATA.dg.txt -rw-r--r-- 1 grid oinstall  1046 Sep  9 10:09 ora.diskmon.txt -rw-r--r-- 1 grid oinstall  1249 Sep  9 10:09 ora.evmd.txt -rw-r--r-- 1 grid oinstall   759 Sep  9 10:09 ora.FRA.dg.txt -rw-r--r-- 1 grid oinstall   827 Sep  9 10:09 ora.LISTENER.lsnr.txt -rw-r--r-- 1 grid oinstall   672 Sep  9 10:09 ora.ons.txt grid@test1:~>more ora.asm.txt NAME=ora.asm TYPE=ora.asm.type ACL=owner:grid:rwx,pgrp:oinstall:rwx,other::r-- ACTION_FAILURE_TEMPLATE= ACTION_SCRIPT= AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX% ALIAS_NAME= ASM_DISKSTRING=/dev/oracleasm/disks AUTO_START=restore CHECK_INTERVAL=1 CHECK_TIMEOUT=30 DEFAULT_TEMPLATE=PROPERTY(RESOURCE_CLASS=asm) ELEMENT(INSTANCE_NAME= %GEN_USR_ORA_INST_NAME%) DEGREE=1 DESCRIPTION=Oracle ASM resource ENABLED=1 GEN_USR_ORA_INST_NAME=+ASM LOAD=1 LOGGING_LEVEL=1 NLS_LANG= NOT_RESTARTING_TEMPLATE= OFFLINE_CHECK_INTERVAL=0 PROFILE_CHANGE_TEMPLATE= RESTART_ATTEMPTS=5 SCRIPT_TIMEOUT=60 SPFILE= START_DEPENDENCIES=hard(ora.cssd) weak(ora.LISTENER.lsnr) START_TIMEOUT=900 STATE_CHANGE_TEMPLATE= STOP_DEPENDENCIES=hard(ora.cssd) STOP_TIMEOUT=600 TYPE_VERSION=1.2 UPTIME_THRESHOLD=1d USR_ORA_ENV= USR_ORA_INST_NAME=+ASM USR_ORA_OPEN_MODE=mount USR_ORA_OPI=false USR_ORA_STOP_MODE=immediate VERSION=11.2.0.3.0

3.2  Change hostname

[root@test 1~]hostname test2 [root@test2]vi /etc/hosts ….. #more /etc/hosts 192.168.1.196    test2

 
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 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 < 12ea3 p align="left">grid    5661   1  0 15:31 ?   00:00:00 /opt/app/oracle/product/11.2/grid/bin/oraagent.bin grid    5706   1 50 15:31 ?   00:00:00 /opt/app/oracle/product/11.2/grid/bin/ohasd.bin restart grid    5741   1 11 15:31 ?    00:00:00 /opt/app/oracle/product/11.2/grid/bin/cssdagent grid    5743   1 15 15:31 ?   00:00:00 /opt/app/oracle/product/11.2/grid/bin/orarootagent.bin grid    5746   1 13 15:31 ?    00:00:00 /opt/app/oracle/product/11.2/grid/bin/oraagent.bin root    5782  4366  0 15:31 pts/0    00:00:00 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

Test2:/opt/app/oracle/product/11.2/grid/crs/install # kill -9 5283 Test2:/opt/app/oracle/product/11.2/grid/crs/install # ps -aef | grep grid 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 grid      5536     1 27 15:30 ?        00:00:00 /opt/app/oracle/product/11.2/grid/bin/ohasd.bin restart grid      5571     1  5 15:30 ?        00:00:00 /opt/app/oracle/product/11.2/grid/bin/cssdagent grid      5573     1  5 15:30 ?        00:00:00 /opt/app/oracle/product/11.2/grid/bin/orarootagent.bin grid      5575     1  7 15:30 ?        00:00:00 /opt/app/oracle/product/11.2/grid/bin/oraagent.bin root      5612  4366  0 15:30 pts/0    00:00:00 grep grid

 

3.7     重新执行roothas.pl配置oracle （has） restart

Test2:#id Test2:#uid=0(root) gid=0(root) groups=0(root) Test2:#cd /opt/app/oracle/product/11.2/grid/crs/install Test2:/opt/app/oracle/product/11.2/grid/crs/install # ./roothas.pl -verbose –deconfig Using configuration parameter file: /opt/app/oracle/product/11.2/grid/crs/install/crsconfig_params CRS-2613: Could not find resource 'ora.cssd'. CRS-4000: Command Stop failed, or completed with errors. CRS-2613: Could not find resource 'ora.cssd'. CRS-4000: Command Delete failed, or completed with errors. CRS-4133: Oracle High Availability Services has been stopped. Successfully deconfigured Oracle Restart stack   Test2:/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. LOCAL ONLY MODE Successfully accumulated necessary OCR keys. Creating OCR keys for user 'root', privgrp 'root'.. Operation successful. CRS-4664: Node test2 successfully pinned. Adding Clusterware entries to inittab

 

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 Name           Type           Target    State     Host           ---------------------------------------------------------------------------------------------- ora....ER.lsnr ora....er.type       ONLINE    ONLINE    test2 ora.cssd       ora.cssd.type    OFFLINE   OFFLINE          ora.diskmon    ora....on.type   OFFLINE   OFFLINE           ora.evmd       ora.evm.type   ONLINE    ONLINE    test2 ora.ons        ora.ons.type    OFFLINE   OFFLINE

 

添加asm资源

grid@test2:/opt/app/oracle/product/11.2/grid/dbs> srvctl -h | grep asm | grep add Usage: srvctl add asm [-l <lsnr_name>] [-p <spfile>] [-d <asm_diskstring>] grid@test2:/opt/app/oracle/product/11.2/grid/dbs>srvctl add asm -l LISTENER -p '' -d '/dev/oracleasm/disks' grid@test2:/opt/app/oracle/product/11.2/grid/dbs> srvctl start asm grid@test2:/opt/app/oracle/product/11.2/grid/dbs> srvctl status asm ASM is running on test2 grid@test2:/opt/app/oracle/product/11.2/grid/dbs> sqlplus SQL*Plus: Release 11.2.0.3.0 Production on Sat Aug 24 16:27:00 2013 Copyright (c) 1982, 2011, Oracle.  All rights reserved.

【注意】此部操作 –d后需要当初选择ASM磁盘时候的磁盘位置，如果手动【change
Path】过，
记得填上如：“/dev/oracleasm/disks”
 
添加db资源

Test2:~ #su - oracle oracle@test2:/opt/app/oracle/product/11.2/grid/bin> ./srvctl  add database -d cdcrm01 -o  /opt/app/oracle/product/11.2/db -p /opt/app/oracle/product/11.2/db/dbs/initcdcrm01 oracle@test2:/opt/app/oracle/product/11.2/grid/bin> srvctl start database -d orcl

 
 查看crs资源信息
