在weblogic用户环境变量中加入export WLS\_STDOUT\_LOG=web.stdout.log  、export WLS\_STDERR\_LOG=web.stderr.log两条，将weblogic控制台和部署工程的全部日志信息打印输出到web.stdout.log文件，随着时间的增长web.stdout.log文件越来越大。如何能实现将输出的日志文件回滚，或按大小重新保存，比如容量到50M后，重新生成新的文件名进行保存？

[Weblogic Windows2008 分离控制台信息到指定日志文件中][Weblogic Windows2008]

默认weblogic中控制台启动之后会在命令行中标准输出一些信息，在没有使用log4j的情况下，想要获取在控制台输出的信息需要进行一些设置  
  
打开C:\\bea\\user\_projects\\domains\\域名\\startWebLogic.cmd文件

set DOMAIN\_HOME=C:\\bea\\user\_projects\\domains\\base\_domain\_second

call "%DOMAIN\_HOME%\\bin\\startWebLogic.cmd" %\*

修改call这行为如下代码

call "%DOMAIN\_HOME%\\bin\\startWebLogic.cmd" 1> stdout.log   2> stderr.log%\*  
  
也可以这样写  
  
call "%DOMAIN\_HOME%\\bin\\startWebLogic.cmd" 1> c:\\stdout.log   2> c:\\stderr.log%\*  
  
重启服务，控制台信息就被转移到你指定的文件中了。希望对大家有所帮助。  
  
使用过程中发现重启服务会出现日志覆盖的情况  
  
解决思路如下:  
在startWebLogic.cmd文件中增加时间相关的字符串，拼接成文件名，保证每次重启的时候文件不会重名  
  
具体代码如下：  
// 设置 yyyy\_mm\_dd 格式的日期  
set sbtmpdate=%date:~0,4%\_%date:~5,2%\_%date:~8,2%  
// 设置 HHmmss 格式的时间  
set sbtmptime=%time:~0,2%%time:~3,2%%time:~6,2%  
// 随机数  
set randomtmp=%random%  
set r=%sbtmpdate%\_%sbtmptime%.%randomtmp%  
  
// 将变量赋值到文件名中  
call "%DOMAIN\_HOME%\\bin\\startWebLogic.cmd" 1>stdMsg-%r%.log 2>stdErr-%r%.log%\*

### [weblogic启动文件的说明 ][weblogic_] ###

情况一：单独的应用服务器（只有一个服务器，这个服务器就是 adminServer）  
startWebLogic.sh内容如下：  
\#!/bin/sh  
   
\# WARNING: This file is created by the Configuration Wizard.  
\# Any changes to this script may be lost when adding extensions to this configuration.  
   
\# \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
\# This script is used to start WebLogic Server for the domain in the  
\# current working directory. This script simply sets the SERVER\_NAME  
\# variable and starts server.  
\#  
\# To create your own start script for your domain, all you need to set is  
\# SERVER\_NAME, then starts the server.  
\#  
\# Other variables that startWLS takes are:  
\#  
\# WLS\_USER     - cleartext user for server startup  
\# WLS\_PW       - cleartext password for server startup  
\# PRODUCTION\_MODE    - true for production mode servers, false for  
\#                development mode  
\# JAVA\_OPTIONS - Java command-line options for running the server. (These  
\#                will be tagged on to the end of the JAVA\_VM and MEM\_ARGS)  
\# JAVA\_VM      - The java arg specifying the VM to run. (i.e. -server,  
\#                -hotspot, etc.)  
\# MEM\_ARGS     - The variable to override the standard memory arguments  
\#                passed to java

这个启动文件会直接在控制台窗口输出weblogic的控制台信息，当你退出是也会关闭weblogic。如果你希望退出控制台不退出weblogic，则你只需要修改此文件的最后一段。在之前加上nohup,并指定输入的日志文件。如：  
   
   
   
   
……………………….  
nohup $\{JAVA\_HOME\}/bin/java $\{JAVA\_VM\} $\{MEM\_ARGS\} $\{JAVA\_OPTIONS\} -Dweblogic.Name=$\{SERVER\_NAME\} -Dweblogic.ProductionModeEnabled=$\{PRODUCTION\_MODE\} -Djava.security.policy="$\{WL\_HOME\}/server/lib/weblogic.policy" weblogic.Server >cdsbserver\_1.log &

注意：MEM\_ARGS="-Xms1248m -Xmx1536m"  
对于32位操作系统最大不能超过2G,在实际中一般最大内存配置1.5G  
   
说明：  
可以设置-Xms(最小使用内存) -Xmx(最大使用内存)，-XX:MaxPermSize  
最大使用内存：  
对于UNIX而言，一般不应超过物理内存的75%;  
对于Windows， 一般不应超过物理内存的50%;  
   
\-XX:MaxPermSize 一般应为mx(最大使用内存)的一半;尝试设置-XX:MaxPermSize=128m  
注意：对于IBM的虚拟机没有MaxPermSize设置，不然系统不能启动
