修改安装目录下的配置文件
比如：f:\app\admin-pc\product\11.2.0\dbhome_1\network\admin\
修改这个目录下的listener.ora和tnsnames.ora
**************************************************************************************
listener.ora：
sid_list_listener =
(sid_list =
(sid_desc =
(sid_name = clrextproc)
(oracle_home = f:\app\xieliangliang\product\11.2.0\dbhome_1)
(program = extproc)
(envs = “extproc_dlls=only:f:\app\admin-pc\product\11.2.0\dbhome_1\bin\oraclr11.dll”)
)
(sid_desc =
(global_dbname = orcl)
(oracle_home = f:\app\admin-pc\product\11.2.0\dbhome_1)
(sid_name = orcl)
)
)
listener =
(description_list =
(description =
(address = (protocol = tcp)(host = 127.0.0.1)(port = 1521))
)
)
adr_base_listener = f:\app\admin-pc
*********************************************************************************
tnsnames.ora:
oraclr_connection_data =
(description =
(address_list =
(address = (protocol = ipc)(key = extproc1521))
)
(connect_data =
(sid = clrextproc)
(presentation = ro)
)
)
orcl =
(description =
(address = (protocol = tcp)(host = 127.0.0.1)(port = 1521))
(connect_data =
(server = dedicated)
(service_name = orcl)
)
)
