JBoss JMX twiddle运行时未注册 [英] JBoss JMX twiddle Runtime not registered

问题描述

我在Solaris 10服务器上的twiddle脚本有问题. 我必须阅读一些属性，例如jboss.system和其他. 取决于jboss服务器的所有属性都可以，但是当我尝试时 从java.lang读取属性，会发生以下错误:

I have a problem with the twiddle script on a Solaris 10 server. I have to read some properties e.g jboss.system and others. All properties depending on the jboss server are fine, but when I try to read properties from java.lang, the following error occurs:

javax.management.InstanceNotFoundException: java.lang:type=Runtime is not registered.

推荐答案

问题是 java.lang:type = Runtime 是平台MBeanServer 注册的MBean，并且默认情况下，twiddle将您连接到 JBoss MBeanServer ，该服务器默认情况下不会注册RuntimeMXBean服务器.

The problem is that java.lang:type=Runtime is a Platform MBeanServer registered MBean and by default, twiddle connects you to the JBoss MBeanServer which by default, will not have the RuntimeMXBean server registered.

假设您只想访问系统属性，最简单的解决方法是将旋转指向JBoss MBean

The easiest way to resolve this, assuming you only want to access system properties, is to point twiddle at the JBoss MBean jboss:name=SystemProperties,type=Service. The MBean exposes:

String get(String key)
String get(String key, String default)

或检索所有值，

Map shopwAll()

其他更费力的解决方案包括:

Other more laborious solutions would inlcude:

• 在JBoss MBeanServer中注册Platform MBeanServer MXBean.参见此问题.
• 在JVM中启用管理代理，并使用JMX连接器连接到Platform MBeanServer.参见此问题.
• 使用附加API 通过进程ID连接到JBoss Server的Platform MBeanServer.然后，您可以引用MXRuntime MBean.

• Register the Platform MBeanServer MXBeans in the JBoss MBeanServer. See this Question.
• Enable the management agent in the JVM and use a JMX Connector to connect to the Platform MBeanServer. See this Question.
• Use the Attach API to connect to the Platform MBeanServer of your JBoss Server by process ID. You can then reference the MXRuntime MBean.
