Ora-12514和Ora-12514解决方法

打开： D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora文件

 在
  SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    ) 
 后面添加：  
    (SID_DESC =
       (GLOBAL_DBNAME = ORCL )
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)  
       (SID_NAME = ORCL )
      )  
 
  最后变成：
 SID_LIST_LISTENER =
   (SID_LIST =
     (SID_DESC =
       (SID_NAME = PLSExtProc)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
       (PROGRAM = extproc)
     ) (SID_DESC =
        (GLOBAL_DBNAME = ORCL )
        (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)  
        (SID_NAME = ORCL )
       )
   )
