各位先辈们，帮下小弟！
我的Oracle 11g用CMD下的sqlplus可以连接成功，但是用Oracle官网的SQL Developer连接时出现如下错误提示：
ORA-12505，TNS:listener does not currently know of SID given in connect descriptor
将SQL Developer中的连接删除都再次配置连接出现提示：
状态：失败-测试失败：IO错误：Socket read timed out
监听文件如下（listener.ora）：
# listener.ora Network Configuration File: C:\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\Oracle\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl )
(ORACLE_HOME = C:\Oracle\product\11.2.0\dbhome_1)
(SID_NAME = orcl )
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.100.92.103)(PORT = 1522))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.100.92.103)(PORT = 1521))
)
)
ADR_BASE_LISTENER = C:\Oracle
这个是tnsnames.ora文件中的内容
------------------
# tnsnames.ora Network Configuration File: C:\Oracle\product
\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
1.ORCL =
2. (DESCRIPTION =
3. (ADDRESS_LIST =
4. (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT =
1521))
5. )
6. (CONNECT_DATA =
7. (SERVICE_NAME = orcl)
8. )
9. )
恳求解决
