Question

我已安装IBM WAS 8.5在启动期间，我可以在控制台中看到

... .rest为了简洁而被移除。

这些vmargs设置在哪个文件中？我需要编辑一个vmarg。

谢谢Scott。我遇到了类似下面的问题。

键和值

之间缺少'='，即等号

…..

Insufficient Java 2 security permissions to start the process!
java.security.policy = null
CodeSource for bootstrap.jar = ProtectionDomain
CodeSource=CodeSource, url=file:/C:/Program%20Files%20(x86)/IBM/WebSphere/AppServer/lib/bootstrap.jar, <no certificates>

您要查找的文件是server.xml。您可以在配置文件夹中的以下位置找到它。

C:\Program Files (x86)\IBM\WebSphere\AppServer\profiles\EbodsMavenSpringWS\config\cells\<CELL_NAME>\nodes\<NODE_NAME>\servers\<SERVER_NAME>\server.xml

使用文本编辑器打开server.xml，找到＆＃39; jvmEntries＆＃39; ID。它应该像下面给出的例子。

<jvmEntries xmi:id="JavaVirtualMachine_1183122130078" verboseModeClass="false" verboseModeGarbageCollection="true" verboseModeJNI="false" initialHeapSize="1280" maximumHeapSize="2048" runHProf="false" hprofArguments="" debugMode="false" debugArgs="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=7777" genericJvmArguments="-Xdisableexplicitgc -Djava.awt.headless=true"> </jvmEntries>

您的JVM参数应列在genericJvmArguments部分下。修改值并启动服务器。

附加说明：已将WAS安装到程序文件（x86）＆＃39;文件夹，您将需要一个具有管理员权限的帐户来运行服务器。

我在哪里可以找到IBM WAS 8.5中的VMARGS
