記一次事件:因爲資源管理器沒有關閉所致使數據庫掛起

數據庫版本12CR1,新裝的兩個節點的RACsql

因爲資源管理器沒有關閉,數據庫早上發生掛起,sqlplus沒法鏈接到實例,後來重啓CRS解決數據庫

crsctl stop crswindows

crsctl start hassession

如何完全關閉資源管理器,以下:oracle

三、完全關閉資源管理器
【oracle】【1節點】
(1). 設置當前的resource manager plan爲空
登陸到cdb修改如下參數
alter system set resource_manager_plan='' scope=both;
(2).修改全部窗口不使用資源管理器的計劃。
登陸到cdb和pdb修改如下設置
select 'execute dbms_scheduler.set_attribute('''||WINDOW_NAME||''',''RESOURCE_PLAN'','''');' from dba_scheduler_windows;
執行查詢結果spa

SQL> show con_name資源

CON_NAME
------------------------------
CDB$ROOTio

SQL> select 'execute dbms_scheduler.set_attribute('''||WINDOW_NAME||''',''RESOURCE_PLAN'','''');' from dba_scheduler_windows;class

'EXECUTEDBMS_SCHEDULER.SET_ATTRIBUTE('''||WINDOW_NAME||''',''RESOURCE_PLAN'','''
--------------------------------------------------------------------------------
execute dbms_scheduler.set_attribute('WEEKEND_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('WEEKNIGHT_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('SUNDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('SATURDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('FRIDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('THURSDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('WEDNESDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('TUESDAY_WINDOW','RESOURCE_PLAN','');
execute dbms_scheduler.set_attribute('MONDAY_WINDOW','RESOURCE_PLAN','');登錄

9 rows selected.

SQL> alter session set container=wjjs;

Session altered.

SQL> show con_name

CON_NAME
------------------------------
WJJS
SQL> select 'execute dbms_scheduler.set_attribute('''||WINDOW_NAME||''',''RESOURCE_PLAN'','''');' from dba_scheduler_windows;

9 rows selected.

(3)並關閉自動分析任務
登陸到cdb和pdb修改如下設置

BEGIN
DBMS_AUTO_TASK_ADMIN.DISABLE(
client_name => 'auto space advisor',
operation => NULL,
window_name => NULL);
END;
/

BEGINDBMS_AUTO_TASK_ADMIN.DISABLE(client_name => 'sql tuning advisor',operation => NULL,window_name => NULL);END;/
