WebLogic告警信息BEA-000450的处理方法

今天在QQ群里面看到的这个问题。日志文件里面的告警信息类似这个样子：

<Warning> <Socket> <BEA-000450> <Socket 10 internal data record unavailable (probable closure due idle timeout), event received 17>
<Warning> <Socket> <BEA-000450> <Socket 3 internal data record unavailable (probable closure due idle timeout), event received 17>
<Warning> <Socket> <BEA-000450> <Socket 4 internal data record unavailable (probable closure due idle timeout), event received 17>
<Warning> <Socket> <BEA-000450> <Socket 8 internal data record unavailable (probable closure due idle timeout), event received 17>
<Warning> <Socket> <BEA-000450> <Socket 7 internal data record unavailable (probable closure due idle timeout), event received 17>
<Warning> <Socket> <BEA-000450> <Socket 1 internal data record unavailable (probable closure due idle timeout), event received 17>

<Jun 12, 2012 12:07:32 PM EDT> <Warning> <Socket> <mydomain.com> <MyServer> <ExecuteThread: '2' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1339517252171>   <BEA-000450> <Socket 525 internal data record unavailable (probable closure due idle timeout), event received 0>
<Jun 12, 2012 12:07:52 PM EDT> <Warning> <Socket> <mydomain.com> <MyServer> <ExecuteThread: '2' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1339517272172>
  <BEA-000450> <Socket 519 internal data record unavailable (probable closure due idle timeout), event received 0>
<Jun 12, 2012 12:10:37 PM EDT> <Warning> <Socket> <mydomain.com> <MyServer> <ExecuteThread: '3' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1339517437176>

1. 根据Oracle官方的说法，BEA-000450这个Warning不会影响应用，可以直接忽略掉。

2. 可以通过控制台的日志筛选器把这个告警信息过滤掉。参考：
https://support.oracle.com/epmos/faces/DocumentDisplay?id=858765.1

第1步：创建日志筛选器
控制台 >> MedRecDomain >> 配置 >> 日志筛选器 >> 新建
名称：LogFilter-BEA-000450
日志筛选表达式：NOT(MSGID = 'BEA-000450')

第2步：把日志筛选器添加到每个实例
控制台 >> 环境 >> 服务器 >> MedRecSvr1 >> 日志记录 >> 一般信息 >> 高级
筛选器：LogFilter-BEA-000450

3. 可以通过控制台设置一个更长的超时时间。参考：
https://support.oracle.com/epmos/faces/DocumentDisplay?id=1052919.1

控制台 >> 环境 >> 服务器 >> MedRecSvr1 >> 协议 >> 一般信息
把“空闲连接超时”和“隧道客户机超时”设置成更大的值

友情提示：超时时间本来就是为了减少死锁和OOM，设置的太大也不好。

4. 打补丁。参考：
