服务器的listener.ora：

# listener.ora Network Configuration File: /ORACLE/u01/app/oracle/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
#      (SID_NAME = PLSExtProc)
      (SID_NAME = sim)
      (ORACLE_HOME = /ORACLE/u01/app/oracle)
      (PROGRAM = extproc)
    )
)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
#        (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.23)(PORT = 1521))
      )
    )
)

客户端的tnsnames.ora：

# tnsnames.ora Network Configuration File: D:\Oracle\product\10.1.0\Client_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

SIM =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.23)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = sim)
      (SID = sim)
    )
)
