oracle 11g rac添加节点前之清除节点信息

参考文档： How to remove/delete a node from Grid Infrastructure Clusterware when the node has failed (文档 ID 1262925.1) 删除数据库实例： 可以使用dbca图形界面删除 也可以使用dbca静默方式删除rac1中的数据库实例： [oracle@rac2 bin]$ dbca -silent -deleteInstance -nodeList rac1 -gdbName orcl -instanceName orcl1 -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 更新RAC节点信息： [oracle@rac2 bin]$ echo $ORACLE_HOME /oracle/app/oracle/product/11.2.0/db_1/oui/bin/ [oracle@hisrac02 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES=hisrac02" Starting Oracle Universal Installer... Checking swap space: must be greater than 500 MB. Actual 62924 MB Passed The inventory pointer is located at /etc/oraInst.loc The inventory is located at /oracle/app/oraInventory 查看集群节点信息： [root@hisrac02 bin]# ./crsctl stat res -t |grep vip ora.hisrac02.vip ora.scan1.vip 删除rac1节点的vip： [root@hisrac02 bin]# ./srvctl remove vip -i rac1 -f 查看集群节点信息： [root@hisrac02 bin]# ./olsnodes -s -t hisrac01 Inactive Unpinned hisrac02 Active Unpinned 从集群中删除节点1： [root@hisrac2 bin]# ./crsctl delete node -n hisrac01 CRS-4661: Node rac1 successfully deleted. 更新集群节点信息： [grid@hisrac02 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES=hisrac02" Starting Oracle Universal Installer...
