weblogic内存溢出

声明:ant,weblogic 都用的是weblogic自带的jdk1.4

 

 

1, 运行-cmd-ant,javac 就报内存溢出

F:/eclipse/workspace/cis-ar>ant
Buildfile: build.xml

sharec:
    [javac] Compiling 3306 source files to F:/eclipse/workspace/biz/out/share

 

 

build.xml--右键--ant.... 打包success.

elcipse中ant打包时内存溢出的解决方法:

设置其参数设置见我上一篇日志。

 

 

 

2,在webloic8.1中发布:

解决方法:

来自:http://blog.csdn.net/chasnoly/archive/2009/02/16/3894919.aspx

一:WebLogic配置问题:
由于WebLogic的配置问题,我们的测试出现了失败情况。原因是为WebLogic分配的内存太少了。通过修改commom/bin/commEnv.cmd文件来增加内存分配。
修改的部分如下:
:bea
if "%PRODUCTION_MODE%" == "true" goto bea_prod_mode
set JAVA_VM=-jrockit
set MEM_ARGS=-Xms768m -Xmx1024m
set JAVA_OPTIONS=%JAVA_OPTIONS% -Xverify:none
goto continue
:bea_prod_mode
set JAVA_VM=-jrockit
set MEM_ARGS=-Xms768m -Xmx1024m//原来是128M~256M,太小了,数据太大
goto continue
结果修改后,没有效果。还是有失败的情况。
发现,原来,在:bea下面还有一段配置信息如下:
:sun
if "%PRODUCTION_MODE%" == "true" goto sun_prod_mode
set JAVA_VM=-client
set MEM_ARGS=-Xms768m -Xmx1024m -XX:MaxPermSize=256m
set JAVA_OPTIONS=%JAVA_OPTIONS% -Xverify:none
goto continue
:sun_prod_mode
set JAVA_VM=-server
set MEM_ARGS=-Xms768m -Xmx1024m -XX:MaxPermSize=256m
goto continue

将这里的内存分配修改后见效。
原因是,上面对第一段代码是为bea自己的JVM设置的,下面的是为Sun的设置的。而WebLogic默认的是Sun的,所以出了毛病。

-------------------------另注:------------------------------

startWeblogic.cmd

文件中调用的是 commEnv.cmd,

在此文件中设定内存大小,可以生效。


call "%WL_HOME%/common/bin/commEnv.cmd"

问题解决了。


    [javac] The system is out of resources.
    [javac] Consult the following stack trace for details.
    [javac] java.lang.OutOfMemoryError

 

BUILD FAILED
file:F:/eclipse/workspace/biz/src/build.xml:150: Compile failed; see the compile
r error output for details.

http://blog.csdn.net/pengchua/archive/2008/07/04/2611065.aspx

在javac的选项里增加 fork="true" memoryMaximumSize="512m"来加在编译时的内存

 用eclipse 开发,在用ant编译web工程时,碰到java.lang.OutOfMemoryError: Java heap space异常

解决办法:

方法1、window->preferences->java->installed jres->edit jre 把default vm arguments 的参数设为-Xms64m -Xmx512

方法2、在window的环境变量中添加JAVA_OPTS=-Xms64m -Xmx512 问题解决

 

 

2,然后我再eclipse中ant打包,
