oracle LISTENER 未监听到oracle实例问题解决：

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = qihezhiye-PC.connectify)(PORT = 1521))

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = mydb)

(ORACLE_HOME = D:\oracle\oradb\mydb)

(SID_NAME = mydb)

)

)

补充或修改红色区域后边这部分。

mydb oracle的sid

ORACLE_HOME 为oracle的home目录，她的下一级目录应该有network这个文件夹。
