1：找到oracle監聽的配置文件：
D:\oracle\product\10.2.0\db_2\NETWORK\ADMIN\listener.ora
2：添加配置（紅色部分）
# listener.ora Network Configuration File: d:\oracle\product\10.2.0\db_2\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\oracle\product\10.2.0\db_2)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_2)
(SID_NAME = ORCL)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = hbzy)(PORT = 1521))
)
)
這個問題我只知道修改方法但卻不太明白問題的發生原因，網上也有大神給出了部分講解但最終都理解不是太透徹存在自己的疑問所以在這裏我就不寫了。有興趣的朋友可以深究下順便告訴我下。呵呵...
