[oracle@cn-111-testdb trace]$ oerr tns 12537
12537, 00000, "TNS:connection closed"
// *Cause: "End of file" condition has been reached; partner has disconnected.
// *Action: None needed; this is an information message.
[oracle@cn-111-testdb trace]$ oerr help
Usage: oerr facility error
Facility is identified by the prefix string in the error message.
For example, if you get ORA-7300, "ora" is the facility and "7300"
is the error. So you should type "oerr ora 7300".
If you get LCD-111, type "oerr lcd 111", and so on.

Non-ADR parameters listed in the sqlnet.ora file are ignored
when ADR is enabled. ADR is enabled by default.
The default value of DIAG_ADR_ENABLED is on. Therefore,
the DIAG_ADR_ENABLED parameter must explicitly be set to off in order
for non-ADR tracing to be used.

具体参数
与防火墙类似的功能，Oracle 提供限制与允许特定的IP或主机名通过Oracle Net来访问数据库。这个功能由sqlnet.ora配置文件来实
现。该文件通常$ORACLE_HOME/network/admin/ 目录下，与tnsnames.ora以及listener.ora位于同一路径。用法也比较简单。通过监听器的
限制，实现轻量级访问限制，比在数据库内部通过触发器进行限制效率要高。
1.通常情况下，更倾向于使用excluded_nodes参数。
tcp.validnode_checking = yes
tcp.invited_nodes = (hostname1,hostname2,ip1,ip2)
tcp.excluded_nodes = (10.103.11.17,hostname1,hostname2)
使用excluded_nodes与invited_nodes的一些特性
不支持通配符的使用(如hostname不能写为svhs0*，IP地址不能写为10.103.11.*）
excluded_nodes与invited_nodes为互斥方式，要么使用前者，要么使用后者
如果tcp.invited_nodes与tcp.excluded_nodes都存在，则tcp.invited_nodes优先
要将本地地址，或者Cluster群集其他节点的地址都加入到允许列表，否则监听器可能无法启动
修改之后，一定要重起监听或reload才能生效，而不需要重新启动数据库
仅提供对TCP/IP协议的支持
