Step1，在监听器中添加

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

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
     )
     (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = jiahuan)(PORT = 1521))     
    )
  )
