环境
操作系统：CentOS release 6.8
数据库：oracle 11.2.0.4.190115
说明：数据库psu 为19年1月份的补丁，可不间断运行，但是开发提示在执行一些批处理的时候，有报错。
错误提示：
开发的报错提示：
2019-03-21 07:24:59,ORA-24381: 数组 DML 出错 ORA-12592: TNS: 包错误 ORA-03106: 致命的双工通信协议错误 ORA-03106: 致命的双工通信协议错误 ORA-03106: 致命的双工通信协议错误 ORA-03106: 致命的双工通信协议错误 ORA-03106: 致命的双工通信协议错误
数据库报错如下：
trace文件如下：
其他时间的报错：
其他时间的trace:
处理方法：
1、alert有超时，领导以为跟华为三层交换机有关（以为中间有防火墙）
后经查询，得知默认没有防火墙。
2、sqlnet.ora
由于领导认为包丢失，他看到alert有超时，就认为需要设置这个。（被我推翻，但是我还是设置了）
3、JDBC驱动问题
由于开发使用的odbc,所以排除。
4、Disable Bind Peeking
alter system set“_optim_peek_user_binds”= false;
并且修改open_cursors
由于此业务是批量插入数据，且用的是绑定变量，用awr 查看，数据库的其他内存指标，等待事件都正常，初步怀疑是跟绑定变量参数有关，修改隐含参数，并且把open_cursors默认值是300修改到1000，后观察两天继续报错（明显没有解决）。
5、未公开的BUG (Doc ID 1361107.1)
Unpublished Bug 18841764 - ORA-12592 TNS:BAD PACKET OR ORA-3137 OR ORA-1 PDIT_BAS_SCPBI
由于数据库是用的最新的PSU，最开始并没觉得是BUG，等我把补丁号复制下来，并没有
已经修复的BUG如下：
