打开SQL*plus时出现无监听程序怎么办？

先看是什么系统，windows 的话 看看监听服务有没有启动，linux 或unix shell 下用　lsnrctl start 尝试一下看能不能启动监听　, 上述没用的话　用netca重新配置一下监听

SQL>

方法一：

在oracle_home下找到lsnrctl.exe 输入 start

方法二

可能认不到实例名

在cmd下运行

set oracle_sid=自己数据库闭举的实例名（大多数尺歼orcl）

网上还有很多解决办法

也许不见得管用，这种问题具体问题具体分析比较好。介绍的这2种您的机器还不行。就去修改一个TNSNAMES.ORA。

***************************************************************

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = E:\oracle\product\10.2.0\db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(SID_NAME = TESTDB)

(ORACLE_HOME = E:\oracle\product\10.2.0\轿困碧db_1)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST = xyz123)(PORT = 1521))

)

)

Listener 改为上面的样子(ORACLE_SID为TESTDB，如果实际不是，自己改一下）.

然后lsnrctl stop

lsnrctl start
