日志文件说明：

**(1).activity.log  **  
   打开方式:Log Analyzer in IBM Support Assistant   or   Log and Trace Analyzer(LTA) in Application Server Toolkit(AST)  
   -consolidates key messages on a particular node(the WAS messages that are written to the System.out stream)  
   -contains extended service information  
**(2).SystemOut.log  and  SystemErr.log**  
   Stardard JVM output and error log  
**(3).startServer.log  and  stopServer.log**  
   Startup and shutdown of the application servers  
**(4).trace.log**  
   Application server code-level events  
   output from diagnostic trace  
**(5).http\_plugin.log**  
   Location:<plugin\_root>/logs/<webserver\_name>  
**(6). native\_stdout.log  and  native\_stderr.log**  
   Native code,JVM  
**(7). FFDC(First failure data capture)**  
   可配置log保存天数  
   Location:<profile\_root>/logs/ffdc/  
   属性文件包括:ffdcRun.properties   exceptionFileMaximunAge

WAS中组件日志的位置：

**(1).HTTP plug-in**  
    Location: Web 服务器 > web\_server\_name > 插件属性  
    log: <plugins\_root>/logs/<web\_server\_name>/http\_plugin.log  
**(2).Embedded HTTP Server**  
    Location: 应用程序服务器 > server\_name > Web 容器 > HTTP 错误和 NCSA 访问记录  
    log: $\{SERVER\_LOG\_ROOT\}/http\_access.log  和  $\{SERVER\_LOG\_ROOT\}/http\_error.log  
**(3).trace.log**  
    Location:记录和跟踪 > server\_name > 诊断跟踪服务  
    log: $\{SERVER\_LOG\_ROOT\}/trace.log  
    说明: <component / group> = <log level>

> log level:detail, info, fatal, severe记录在SystemOut.log中， 只有fine, finer, finest,是记录在trace.log中

WAS5.x 和WAS6.x中记日志的不同

>      WAS5.x: com.ibm.\*=all=enabled 或 com.ibm.\*=all=disabled  
>      WAS6.x: com.ibm.\*=info 或  com.ibm.\*=all

使用wasadmin改配置

>      set server \[$AdminConfig getid /Cell:<mycell>/Node:<mynode>/Server:<myserver>/\]  
>      set tc \[$AdminConfig list TraceService $server\]  
>      $AdminConfig modify $tc \{ \{startupTraceSpecification com.ibm.ws.\*=all=enabled\}\}  
>      $AdminConfig save

使用wasadmin改运行

>      set ts \[$AdminControl queryNames type=TraceService,node=<mynode>,process=<myserver>,\*\]  
>      $AdminControl setAttribute $ts traceSpecification com.ibm.ws.\*=all=enabled
