ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

解决办法是修改D:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN下的listener.ora

 

# listener.ora Network Configuration File: d:\app\Administrator\product\11.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER = 
  (SID_LIST = 
    (SID_DESC = 
      (SID_NAME = PLSExtProc) 
      (ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1) 
      (PROGRAM = extproc) 
    ) 
    (SID_DESC = 
      (GLOBAL_DBNAME = orcl) 
      (ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1) 
      (SID_NAME = orcl) 
    ) 
  ) 
LISTENER = 
  (DESCRIPTION_LIST = 
    (DESCRIPTION = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 
    ) 
  )

 

重启oracleservice和listening两个服务即可。
