【问题描述】：
我正在尝试使用 JVisualVM 监控 IBM Websphere，但无法连接。 错误提示“无法连接到使用服务：jmx:rmi:///jndi/rmi:///jmxrmi” 这是第一次在 WAS 中使用 IBM JDK。这在我们的旧 Solaris 服务器上运行良好。
规格和配置。
- IBM Websphere 8.0.0.5
- 红帽 Linux
- Java 版本 = 1.6.0，Java 编译器 = j9jit26，Java VM 名称 = IBM J9 虚拟机
- JVM 参数：
-Djavax.management.builder.initial= -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=19823 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun .management.jmxremote.authenticate=false -Xgcpolicy:gencon -verbose:gc -Djava.rmi.server.hostname=
VISUAVM 错误。

检查完毕。
- 在服务器中公开 JMX 端口。我可以看到它正在听。 我什至可以使用 telnet 在我的 笔记本电脑。
- 我在 websphere 端没有看到任何错误日志。
【问题讨论】：
-
确保
-Djava.rmi.server.hostname=拥有您的Websphere 服务器的IP 地址。 -
@TomasHurka 是的，包括在内。奇怪的是，由于我收到 SSL 错误，因此 ssl=false 似乎无法正常工作。你知道我是否需要附加一些库才能在 IBM JDK 中进行这项工作？在热点JVM中使用相同的配置并且没有错误
