刪除節點
1、刪除資料庫例項 本次實驗是刪除stuaapp02節點
- 在另外一個節點執行
[oracle@stuaapp01 rdbms]$ dbca -silent -deleteInstance -nodeList stuaapp02 -gdbName lenovo -instanceName lenovo2 -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/lenovo4.log" for further details. 驗證： SQL> select thread#,status from v$thread; THREAD# STATUS ---------- ------ 1 OPEN [oracle@stuaapp01 rdbms]$ srvctl config database -d lenovo Database unique name: lenovo Database name: Oracle home: /u01/app/oracle/product/11.2.0/dbhome_1 Oracle user: oracle Spfile: +DATA/LENOVO/spfilelenovo.ora Domain: Start options: open Stop options: immediate Database role: PRIMARY Management policy: AUTOMATIC Server pools: lenovo Database instances: lenovo1 Disk Groups: DATA,FRA Mount point paths: Services: Type: RAC Database is administrator managed
2、刪除Oracle RAC軟體
- 1 在需要刪除的節點執行
[oracle@stuaapp02 trace]$ srvctl disable listener -l listener -n stuaapp02
[oracle@stuaapp02 trace]$ srvctl stop listener -l listener -n stuaapp02
- 2 在需要刪除的節點執行
[oracle@stuaapp02 trace]$ cd $ORACLE_HOME/oui/bin/ [oracle@stuaapp02 bin]$ pwd /u01/app/oracle/product/11.2.0/dbhome_1/oui/bin [oracle@stuaapp02 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=stuaapp02" -local Starting Oracle Universal Installer... Checking swap space: must be greater than 500 MB. Actual 3855 MB Passed The inventory pointer is located at /etc/oraInst.loc The inventory is located at /u01/app/oraInventory 'UpdateNodeList' was successful.
- 3 在需要刪除的節點執行
[oracle@stuaapp02 bin]$ cd $ORACLE_HOME/deinstall/
[oracle@stuaapp02 deinstall]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/deinstall
[oracle@stuaapp02 deinstall]$ ./deinstall -local
Checking for required files and bootstrapping ...
Please wait ...
- 4 在其他節點執行
[oracle@stuaapp01 rdbms]$ cd $ORACLE_HOME/oui/bin/
[oracle@stuaapp01 bin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/oui/bin
[oracle@stuaapp01 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=stuaapp01"
Starting Oracle Universal Installer...
3、刪除Node節點
- 1 確認目錄
[grid@stuaapp01 ~]$ echo $ORACLE_HOME
/u01/app/11.2.0/grid
- 2 確定需要刪除的節點名稱
[grid@stuaapp01 ~]$ olsnodes -s -t
stuaapp01 Active Unpinned
stuaapp02 Active Unpinned
- 3 禁用叢集應用和守護程序
在需要刪除的節點上，使用root使用者執行指令碼
[root@stuaapp02 install]# pwd
/u01/app/11.2.0/grid/crs/install
[root@stuaapp02 install]# ./rootcrs.pl -deconfig -force
- 4 從叢集中刪除節點
在其他節點執行，使用root使用者執行
原文操作# crsctl delete node -n node_to_be_deleted
[root@stuaapp01 ~]# crsctl delete node -n stuaapp02
CRS-4661: Node stuaapp02 successfully deleted.
- 5 在需要刪除的節點上，使用grid使用者執行
原文操作$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={node_to_be_deleted}" CRS=TRUE -silent -local
[grid@stuaapp02 bin]$ pwd
/u01/app/11.2.0/grid/oui/bin
[grid@stuaapp02 bin] ./runInstaller -updateNodelist ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=stuaapp02" CRS=TRUE -silent -local
確認檔案inventory.xml沒有被更新
- 6 在需要刪除的節點上執行，使用grid使用者執行
[grid@stuaapp02 deinstall]$ pwd
/u01/app/11.2.0/grid/deinstall
[grid@stuaapp02 deinstall]$ ./deinstall -local
注意：如果不指定-local選項，那麼預設將會把所有的叢集資訊全部刪除，這是非常危險的操作
執行此命令過程中需要進行多次手動配置，請注意！！！！
- 7 在其他節點執行
使用grid使用者執行
原文操作$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE -silent
[grid@stuaapp01 bin]$ pwd
/u01/app/11.2.0/grid/oui/bin
[grid@stuaapp01 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=stuaapp01" CRS=TRUE -silent
使用oracle使用者執行
原文操作$ ./runInstaller -updateNodeList ORACLE_HOME=ORACLE_HOME"CLUSTER_NODES={remaining_nodes_list}"
[oracle@stuaapp01 bin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/oui/bin
[oracle@stuaapp01 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=stuaapp01"
- 8 驗證，使用grid使用者執行
原文操作$ cluvfy stage -post nodedel -n node_list [-verbose]
[grid@stuaapp01 ~]$ cluvfy stage -post nodedel -n stuaapp02 -verbose
新增節點
1、增加叢集，在grid使用者
[grid@stuaapp01 bin]$ cluvfy stage -pre nodeadd -n stuaapp02
[grid@pipi1 bin]$ export IGNORE_PREADDNODE_CHECKS=Y
[grid@stuaapp01 bin]$ pwd
/u01/app/11.2.0/grid/oui/bin
[grid@stuaapp01 bin]$ ./addNode.sh -silent "CLUSTER_NEW_NODES={stuaapp02}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={stuaapp02-vip}"
[root@stuaapp02 oracle]# /u01/app/11.2.0/grid/root.sh
2、增加oracle軟體 在oracle使用者
[oracle@stuaapp01 bin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/oui/bin
[oracle@stuaapp01 bin]$ ./addNode.sh "CLUSTER_NEW_NODES={stuaapp02}"
3、增加例項
在有例項的節點執行
dbca -silent -addInstance -nodeList stuaapp02 -gdbName lenovo -instanceName lenovo2 -sysDBAUserName sys -sysDBAPassword oracle
4、新增redolog--實驗中並沒有做這些操作
SQL> alter database add logfile thread 2 group 4 '+DATA' size 50m;
SQL> alter database add logfile thread 2 group 5 '+DATA' size 50m;
SQL> alter database add logfile thread 2 group 6 '+DATA' size 50m;
SQL> alter database enable public thread 2;
SQL> create undo tablespace undotbs2 datafile '+data' size 50m;
SQL> alter system set undo_tablespace=undotbs2 scope=spfile sid='lenovo2';
SQL> alter system set instance_number=2 scope=spfile sid='lenovo2';
SQL> alter system set cluster_database_instances=2 scope=spfile sid='*';
5、新增例項到叢集
[oracle@stuaapp01 dbs]$ srvctl add instance -d lenovo -i lenovo2 -n stuaapp02
[oracle@stuaapp01 dbs]$ srvctl status database -d lenovo
Instance lenovo1 is running on node stuaapp01
Instance lenovo2 is running on node stuaapp02
[oracle@stuaapp01 dbs]$ srvctl stop instance -d lenovo -i lenovo2
[oracle@stuaapp01 dbs]$ srvctl status database -d lenovo
Instance lenovo1 is running on node stuaapp01
Instance lenovo2 is not running on node stuaapp02
[oracle@stuaapp01 dbs]$ srvctl start instance -d lenovo -i lenovo2
[oracle@stuaapp01 dbs]$ srvctl stop instance -d lenovo -i lenovo2
[oracle@stuaapp01 dbs]$ srvctl start instance -d lenovo -i lenovo2
[oracle@stuaapp01 dbs]$ exit
