ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(sid = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
解决方案
提示的很明显了：SID错误，这类似mysql的url、用户名、密码中的一项错误；解决方法对症下药就行：找到安装目录下的oci目录下的tnsnames.ora文件，这里面会配置所有的连接地址、端口 检查你登陆的这个这几项是否有错误
解决方案二：
这里是我的里面的内容，你自己对着看吧！

(SERVICE_NAME = weboffice)
)
)
EDW_JCSS =
(DESCRIPTION =

UC =
(DESCRIPTION =

)
(CONNECT_DATA =

)
)
解决方案三：
关键问题就在sid=orcl这段了；看看你装的oracle 或者公司服务器oracle的版本，对应不同版本来设置这个值；比如：SID = oracle9i
