oracle报ORA-12541无监听错误

Question

cmd启动报TNS-12560: TNS: 协议适配器错误 TNS-00530: 协议适配器。

这是listener.ora的文件：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\software\orcal\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\software\orcal\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = C:\software\orcal\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.23.15)(PORT = 1521))
)
)

ADR_BASE_LISTENER = C:\software\orcal
网上说的注册表也没有问题：
