进入oracle安装目录\product\11.2.0\dbhome_1\NETWORK\ADMIN，修改listener.ora和tnsnames.ora，修改host
我的网络IP为192.168.6.24：
listener.ora
# listener.ora Network Configuration File: D:\tools\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools. SID_LIST_LISTENER =

(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\tools\oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = D:\tools\oracle\product\11.2.0\dbhome_1)
(SID_NAME = ORCL)
)
) LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
