默認oracle的共享服務是註冊到動態註冊服務裏面的

設置共享服務器：
alter system set DISPATCHERS = '(PROTOCOL=TCP)(DISPATCHERS=3)';
alter system set shared_server_sessions=200 scope=both;
alter system set max_dispatchers=10 scope=both;
alter system set shared_servers=10 scope=both;
alter system set max_shared_servers=30 scope=both;

因爲服務prod3.oracle.com 裏面沒有dispatcher，所以當你作爲共享服務連接的時候會報錯ORA-12523

將共享服務註冊到靜態監聽裏面
修改參數
alter system set dispatchers='(PROTOCOL=TCP)(DISPATCHERS=3)(SERVICE=PROD3,PROD3.ORACLE.COM)';
指定service參數
