Oracle 10g 報ORA-12514錯誤

解決方案：

　　　修改listener.ora文件內容。

        路徑：盤符：\oracle\product\10.2.0\db_1\network\ADMIN\

        打開文件：

# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
　　(SID_DESC =
 　　　　(SID_NAME = PLSExtProc)
　　　　 (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
　　　　 (PROGRAM = extproc)
　　)
)

LISTENER =
(DESCRIPTION_LIST =
　　(DESCRIPTION =
　　　　(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
　　　　(ADDRESS = (PROTOCOL = TCP)(HOST = CLR-PC)(PORT = 1521))
　　)
)

　　在SID_LIST_LISTENER 項添加

     (SID_DESC =
       (GLOBAL_DBNAME = CLR)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)  
       (SID_NAME = CLR)
      )

　　添加后變為：

# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

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 = CLR)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)  
       (SID_NAME = CLR)
      )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = CLR-PC)(PORT = 1521))
    )
  )

　　SID_NAME和GLOBAL_DBNAME 要換成你自己的庫。

     然后重啟OracleOraDb10g_home1TNSListener 服務，就ok了，測試可行。
