oracle集群节点切换不,Oracle 11gR2 RAC集群单节点关闭开启

發布時間：2025/3/21 编程问答 35 豆豆

生活随笔收集整理的這篇文章主要介紹了 oracle集群节点切换不,Oracle 11gR2 RAC集群单节点关闭开启小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

Oracle Product集群因OS需要打patch需要單獨關閉節點進行維護，機器為個人測試Oracle 11g R2測試集群

操作步驟

--確認集群的db_unique_name,本初的db_unique_name為orcl

SQL> show parameter name

NAME ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? TYPE ? ? ? ?VALUE

------------------------------------ ----------- ------------------------------

cell_offloadgroup_name ? ? ? ? ? ? ? string

db_file_name_convert ? ? ? ? ? ? ? ? string

db_name ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?string ? ? ?orcl

db_unique_name ? ? ? ? ? ? ? ? ? ? ? string ? ? ?orcl

global_names ? ? ? ? ? ? ? ? ? ? ? ? boolean ? ? FALSE

instance_name ? ? ? ? ? ? ? ? ? ? ? ?string ? ? ?orcl2

lock_name_space ? ? ? ? ? ? ? ? ? ? ?string

log_file_name_convert ? ? ? ? ? ? ? ?string

processor_group_name ? ? ? ? ? ? ? ? string

service_names ? ? ? ? ? ? ? ? ? ? ? ?string ? ? ?orcl

--確認集群的instance_name

SQL> select instance_name,status from gv$instance;

INSTANCE_NAME ? ?STATUS

---------------- ------------

orcl2 ? ? ? ? ? ?OPEN

orcl1 ? ? ? ? ? ?OPEN

#本處的兩個實例名為orcl1 和 orcl2

--關閉node1監聽，確保應用無法通過監聽連接數據庫

[grid@oranode1 ~]$ srvctl stop listener -n oranode1

#使用crs_stat -t -v命令或者使用srvctl status listener命令檢查監聽運行情況

[grid@oranode1 ~]$ srvctl status listener -n oranode1

Listener LISTENER is enabled on node(s): oranode1

Listener LISTENER is not running on node(s): oranode1

[grid@oranode2 ~]$ srvctl status listener -n oranode2

Listener LISTENER is enabled on node(s): oranode2

Listener LISTENER is running on node(s): oranode2

#確保關閉前實例上沒有session在執行，如果有停機窗口的話建議殺一次local=no的會話

[oracle@oranode1 ~]$ ps -ef |grep -i local=no |wc -l

[oracle@oranode1 ~]$ ps -ef |grep -i local=no |cut -c 10-15|xargs kill -9

kill 7803: No such process

--關閉集群節點一上的數據庫實例

[grid@oranode1 ~]$ srvctl stop instance -o immediate -d orcl -i orcl1

[oracle@oranode1 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Thu Apr 13 12:41:30 2017

Connected to an idle instance.

#確保數據庫實例已經被關閉

[grid@oranode1 ~]$ crs_stat -t -v

#或者使用srvctl status database 命令檢查

[grid@oranode1 ~]$ srvctl status database -d orcl

--關閉集群節點一的ASM服務

#此處關閉asm實例在報錯，由于ora.CLUSTER_DISK的存在，指明此需要強制指定參數-f才能關閉ASM.此處如果是執行-f參數的話將會已shutdown abort的方式強制關閉數據庫，生產環境上執行此命令有風險

--#11Gr2下，ASM是cssd下管理的，需要把cssd關閉后，才能關閉ASM服務

--切換到root下執行crsctl stop crs的方式關閉整個集群節點一的CRS服務
