1、查看节点删除前的资源状态
用集群资源查看命令查看一下状态
1 [grid@lvmrac1 ~]$crsctl stat res ‐t

2、删除instance（在节点2进行节点1的删除）
1）检查OCR备份(grid)
36 [grid@lvmrac1 ~]$ ocrconfig ‐showbackup
37 lvmrac1 2017/03/30 05:58:31 /u01/11.2.0/grid/cdata/lvmrac‐cluster/backup00.ocr
38 lvmrac1 2017/03/30 01:58:29 /u01/11.2.0/grid/cdata/lvmrac‐cluster/backup01.ocr
39 lvmrac1 2017/03/29 21:58:28 /u01/11.2.0/grid/cdata/lvmrac‐cluster/backup02.ocr
40 lvmrac1 2017/03/29 21:58:28 /u01/11.2.0/grid/cdata/lvmrac‐cluster/day.ocr
41 lvmrac1 2017/03/29 21:58:28 /u01/11.2.0/grid/cdata/lvmrac‐cluster/week.ocr
2）删除要删除节点的instance(oracle)
dbca -silent -deleteDatabase -sourceDB lvmrac1 -sysDBAUserName sys -sysDBAPassword xxxx
3）在保留的节点禁用删除节点的log thread(oracle)
1 SQL> ALTER DATABASE DISABLE THREAD 1; 2
3 Database a1tered.
3、移除rac
1）清除删除节点的监听(grid)
RAC中grid用户管理数据库的监听，还管理数据库的ASM；oracle只负责数据库
1 [grid@lvmrac2 ~]$ srvctl disable listener ‐l listener ‐n lvmrac1
2 [grid@lvmrac2 ~]$ srvctl stop listener ‐l listener ‐n lvmrac1
2）在删除节点，同步oraInventory库
进入$ORACLE_HOME/oui/bin(grid、oracle)
[grid@lvmrac1 bin]$ ./runInstaller ‐updateNodeList ORACLE_HOME=/u01/11.2.0/grid/ "CLUSTER_NODES={lvmrac1}" ‐local
5 Starting Oracle Universal Installer... 6
7 Checking swap space: must be greater than 500 MB. Actual 4031 MB Passed
8 The inventory pointer is located at /etc/oraInst.loc
9 The inventory is located at /u01/app/oraInventory 10 'UpdateNodeList ' was successful.
11
12 [oracle@lvmrac1 bin]$ ./runInstaller ‐updateNodeList
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1/ "CLUSTER_NODES={lvmrac1}" ‐local
13 Starting Oracle Universal Installer... 14
15 Checking swap space: must be greater than 500 MB. Actual 4026 MB Passed
16 The inventory pointer is located at /etc/oraInst.loc
17 The inventory is located at /u01/app/oraInventory 18 'UpdateNodeList ' was successful.
3）在删除节点删除软件
1 进入$ORACLE_HOME/de install
2 [grid@lvmrac1 de install]$ ./de install ‐local
3 按照提示，一步一步进行 4
5 [oracle@lvmrac1 de install]$ ./de install ‐local
6 按照提示，一步一步进行
4）在保留节点，同步oraInventory库
进入$ORACLE_HOME/oui/bin(grid、oracle)
2 [grid@lvmrac2 bin]$ ./runInstaller ‐updateNodeList ORACLE_HOME=/u01/11.2.0/grid/ "CLUSTER_NODES={lvmrac2}"
3 Starting Oracle Universal Installer... 4
5 Checking swap space: must be greater than 500 MB. Actual 2763 MB Passed
6 The inventory pointer is located at /etc/oraInst.loc
7 The inventory is located at /u01/app/oraInventory 8 'UpdateNodeList ' was successful.
9
10 [oracle@lvmrac2 bin]$ ./runInstaller ‐updateNodeList
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1/ "CLUSTER_NODES={lvmrac2}"
11 Starting Oracle Universal Installer... 12
13 Checking swap space: must be greater than 500 MB. Actual 2883 MB Passed
14 The inventory pointer is located at /etc/oraInst.loc
15 The inventory is located at /u01/app/oraInventory 16 'UpdateNodeList ' was successful.
