TNS-12547，Linux Error: 104: Connection reset by peer
配置开启oracle listener 的时候报这个错，google 了一下 ，原文链接：http://space.itpub.net/35489/viewspace-629063
修改了一下 /etc/hosts 文件 将 127.0.0.1 localhost.localdomain localhost
重启监听就好了。
Listener.ora 文件如下，配置应该没有错误：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.13.13.188)(PORT = 1526))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/product/oracle)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = b2b)
(ORACLE_HOME = /u01/product/oracle)
(SID_NAME = b2b)
)
)
开启监听的时候报错 ：

后来发现 /etc/hosts 中的 127.0.0.1 对应的不是localhost 而是实际的主机名称，如下：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 MXB2B-WEB01
10.13.13.188 MXB2B-WEB01
修改/etc/hosts 为下面的形式 ：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.13.13.188 MXB2B-WEB01
再次开启监听， OK .
