公司目前在进行去o，为保证生产操作，搭建了模拟生产环境的多节点rac集群，作为一学就会，一会就废系列，今天推出该系列的第二篇，和11g rac删除节点不同，10g rac 删除稍有差别，后面会奉上该系列第三篇，10g的集群删除。
本次验证测试环境为oracle 11g rac 三节点集群环境，现计划模拟下线其中一个节点。
1.1 现有集群节点信息
| 主机名 | public-ip | virtual-ip | scan-ip | private-ip | 操作系统版本 | 数据库版本 |
|---|---|---|---|---|---|---|
| host210 | 192.168.17.136 | 192.168.17.103 | 192.168.17.108 | 10.90.1.36 | centos release 6.10 (final) | 11.2.0.4 |
| host211 | 192.168.17.137 | 192.168.17.104 | 192.168.17.108 | 10.90.1.37 | centos release 6.10 (final) | 11.2.0.4 |
| host212 | 192.168.17.139 | 192.168.17.105 | 192.168.17.108 | 10.90.1.38 | centos release 6.10 (final) | 11.2.0.4 |
现计划将host212从集群中下线，将rac集群修改为 二节点rac集群。
2.1 检查css服务
检查现有集群节点css服务是否正常。
--- 使用grid用户，任一节点 [root@host210 ~]# su - grid [grid@host210 ~]$ olsnodes -s -t host210 active unpinned host211 active unpinned host212 active unpinned ## unpinned代表正常 ## 若是pinned代表不正常，需执行 [grid@hostxxx ~] crsctl unpin css -n hostname 【hostname即为不正常节点】
2.2 检查集群及数据库状态
集群状态信息如下：
[grid@host210 ~]$ crs_stat -t name type target state host ------------------------------------------------------------ ora.crs.dg ora....up.type online online host210 ora.data.dg ora....up.type online online host210 ora....er.lsnr ora....er.type online online host210 ora....n1.lsnr ora....er.type online online host210 ora.asm ora.asm.type online online host210 ora.cvu ora.cvu.type online online host210 ora.gsd ora.gsd.type offline offline ora....sm1.asm application online online host210 ora....10.lsnr application online online host210 ora....210.gsd application offline offline ora....210.ons application online online host210 ora....210.vip ora....t1.type online online host210 ora....sm2.asm application online online host211 ora....11.lsnr application online online host211 ora....211.gsd application offline offline ora....211.ons application online online host211 ora....211.vip ora....t1.type online online host211 ora....sm3.asm application online online host212 ora....12.lsnr application online online host212 ora....212.gsd application offline offline ora....212.ons application online online host212 ora....212.vip ora....t1.type online online host212 ora....network ora....rk.type online online host210 ora.oc4j ora.oc4j.type online online host210 ora.ons ora.ons.type online online host210 ora.oradb.db ora....se.type online online host210 ora.scan1.vip ora....ip.type online online host210
数据库状态信息如下：

2.3 删除数据库实例
删除数据库实例有两种方式，一种可通过图形的方式，另一种可通过命令的方式。
2.3.1 图形方式
2.3.2 命令方式
--- 使用oracle用户在任一未被删除节点执行 [root@host210 ~]# su - oracle [oracle@host210 ~]$ dbca -silent -deleteinstance -nodelist host212 -gdbname oradb -instancename oradb3 -sysdbausername sys -sysdbapassword oracle deleting instance 1% complete 2% complete 6% complete 13% complete 20% complete 26% complete 33% complete 40% complete 46% complete 53% complete 60% complete 66% complete completing instance management. 100% complete look at the log file "/u01/app/oracle/cfgtoollogs/dbca/oradb.log" for further details. -- 通过如下方式查询，可以看到实例3已经被删除 [oracle@host210 ~]$ sqlplus / as sysdba sql*plus: release 11.2.0.4.0 production on thu sep 21 11:05:38 2023 米乐app官网下载 copyright (c) 1982, 2013, oracle. all rights reserved. connected to: oracle database 11g enterprise edition release 11.2.0.4.0 - 64bit production with the partitioning, real application clusters, automatic storage management, olap, data mining and real application testing options sql> set long 99999 head off pages 0 lines 1000 sql> select inst_id,instance_number,instance_name,host_name,status,thread# from gv$instance; 1 1 oradb1 host210 open 1 2 2 oradb2 host211 open 2 ## /u01/app/oracle/cfgtoollogs/dbca/oradb.log 日志信息如下： [root@host210 ~]# more /u01/app/oracle/cfgtoollogs/dbca/oradb.log the database configuration assistant will delete the oracle instance and its associated ofa directory structure. all information about this instance will be deleted. do you want to proceed? deleting instance dbca_progress : 1% dbca_progress : 2% dbca_progress : 6% dbca_progress : 13% dbca_progress : 20% dbca_progress : 26% dbca_progress : 33% dbca_progress : 40% dbca_progress : 46% dbca_progress : 53% dbca_progress : 60% dbca_progress : 66% completing instance management. dbca_progress : 100%
2.4 停被删除节点监听
-- 使用grid用户在任一节点操作 [grid@host210 ~]$ srvctl config listener -a name: listener network: 1, owner: grid home:/u01/app/11.2.0/grid on node(s) host210,host211,host212 end points: tcp:1521 [grid@host210 ~]$ srvctl disable listener -l listener -n host212 [grid@host210 ~]$ srvctl stop listener -l listener -n host212 -- 查看集群状态，可看到被删除实例host212监听已停 [grid@host210 ~]$ crs_stat -t name type target state host ------------------------------------------------------------ ora.crs.dg ora....up.type online online host210 ora.data.dg ora....up.type online online host210 ora....er.lsnr ora....er.type online online host210 ora....n1.lsnr ora....er.type online online host210 ora.asm ora.asm.type online online host210 ora.cvu ora.cvu.type online online host210 ora.gsd ora.gsd.type offline offline ora....sm1.asm application online online host210 ora....10.lsnr application online online host210 ora....210.gsd application offline offline ora....210.ons application online online host210 ora....210.vip ora....t1.type online online host210 ora....sm2.asm application online online host211 ora....11.lsnr application online online host211 ora....211.gsd application offline offline ora....211.ons application online online host211 ora....211.vip ora....t1.type online online host211 ora....sm3.asm application online online host212 ora....12.lsnr application offline offline ora....212.gsd application offline offline ora....212.ons application online online host212 ora....212.vip ora....t1.type online online host212 ora....network ora....rk.type online online host210 ora.oc4j ora.oc4j.type online online host210 ora.ons ora.ons.type online online host210 ora.oradb.db ora....se.type online online host210 ora.scan1.vip ora....ip.type online online host210
2.5 第一次更新集群列表信息
-- 在被删除的host212节点使用oracle用户更新集群列表信息 [root@host212 ~]# su - oracle [oracle@host212 ~]$ $oracle_home/oui/bin/runinstaller -updatenodelist oracle_home=$oracle_home "cluster_nodes={host212}" -local starting oracle universal installer... checking swap space: must be greater than 500 mb. actual 65535 mb passed the inventory pointer is located at /etc/orainst.loc the inventory is located at /u01/app/orainventory 'updatenodelist' was successful.
2.6 删除数据库oracle软件

在任一非删除节点操作执行。
-- 使用grid用户执行 [root@host210 ~]# su - grid [grid@host210 ~]$ $oracle_home/oui/bin/runinstaller -updatenodelist oracle_home=$oracle_home "cluster_nodes={host210,host211}" crs=true starting oracle universal installer... checking swap space: must be greater than 500 mb. actual 65535 mb passed the inventory pointer is located at /etc/orainst.loc the inventory is located at /u01/app/orainventory 'updatenodelist' was successful.
2.15 清除被删节点信息
若要清空被删除节点上的数据库目录及文件信息，可在被删除节点使用root用户执行。
[root@host212 ~]# rm -rf /tmp/* [root@host212 ~]# rm -rf /tmp/.* [root@host212 ~]# rm -f /usr/local/bin/dbhome [root@host212 ~]# rm -f /usr/local/bin/oraenv [root@host212 ~]# rm -f /usr/local/bin/coraenv [root@host212 ~]# rm -rf /opt/orclfmap #删除数据库软件安装目录 [root@host212 ~]# rm -rf /u01/app/*
在任一非被删除节点执行。
