--靜態註冊服務prod3.oracle.com裡面沒有dispatcher,動態註冊prod3裡面有

cat tnsnames.ora

PROD3_S =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (server=shared)
      (SERVICE_NAME =prod3.oracle.com)
    )
  )

PROD3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (server=dedicated)
      (SERVICE_NAME =prod3.oracle.com)
    )
  )

因為服務prod3.oracle.com 裡面沒有dispatcher，所以當你作為共用服務串連的時候會報錯ORA-12523

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