Navicat Premium 连接O​r​a​c​l​e​ ​出现o​r​a​-​1​2​5​0​5​ ​错​误​解​决​方​案

找到listener.ora文件：我的Oracle是安装在F盘，

路径为：F:\oracle\product\10.2.0\db_1\network\admin\listener.ora  改动前的配置例如以下：

# listener.ora Network Configuration File: F:\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 = F:\oracle\product\10.2.0\db_1)      

(PROGRAM = extproc)     )   )  

LISTENER =    (DESCRIPTION_LIST =    

(DESCRIPTION =       

 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))       

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))     ) ) 

 

改动后的配置例如以下：

# listener.ora Network Configuration File: F:\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 = F:\oracle\product\10.2.0\db_1)      

(PROGRAM = extproc)     )  

    (SID_DESC =              

 (GLOBAL_DBNAME = ORCL)        

 (ORACLE_HOME =
F:\oracle\product\10.2.0\db_1)       

(SID_NAME = ORCL)       )

)  

 LISTENER =    (DESCRIPTION_LIST =    

 (DESCRIPTION =        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))      

  (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))     )   )
