Oracle--單實例下的service管理

1.創建service

service_name、network_name兩個參數是必須的：前者表示數據字典內部使用的名稱；后者是監聽中對應的名稱。

BEGIN
  DBMS_SERVICE.create_service(
    service_name => 'my_new_service',
    network_name => 'my_new_service'
  );
END;
/

2.啟動service

BEGIN
  DBMS_SERVICE.start_service(
    service_name => 'my_new_service'
  );
END;
/

3.修改service

BEGIN
  DBMS_SERVICE.modify_service(
    service_name => 'my_new_service',
    goal         => DBMS_SERVICE.goal_throughput
  );
END;
/

4.關閉service

BEGIN
  DBMS_SERVICE.stop_service(
    service_name => 'my_new_service'
  );
END;
/

5.刪除service

BEGIN
  DBMS_SERVICE.delete_service(
    service_name => 'my_new_service'
  );
END;
/

6.斷開service的所有會話

DBMS_SERVICE.post_transaction：事務結束，會話就斷開。這是默認設置(value:0)。

DBMS_SERVICE.immediate：會話立即斷開連接(value:1)

DBMS_SERVICE.noreplay：會話立即斷開連接，標記為不再replay(value:2)

BEGIN
  DBMS_SERVICE.disconnect_session(
   service_name      => 'my_new_service',
   disconnect_option => DBMS_SERVICE.immediate
  );
END;
/

7.查看service狀態

SELECT name,network_name FROM dba_services;
SELECT name,network_name FROM v$active_services;
