Java Virtual Machine uses Java bytecode, which translates the version of the original Java code. The launcher is the one that starts and sets up the JVM with the right memory, security, and other settings. If you have issues with the JVM launcher, the methods mentioned below can help you...
A dedicated thread is created to start each application server Java virtual machine (JVM). The JVMs with dedicated threads in this thread pool are the JVMs that are started in parallel whenever the node agent starts. You can specify an integer from 0 - 5 as the value for this property....

Method area is created on virtual machine startup, shared among all Java virtual machine threads and it is logically part of heap area. It stores per-class structures such as the run-time constant pool, field and method data, and the code for methods and constructors. Java的对象行为(方法、...
final AttachProvider provider() Returns the provider that created this virtual machine. abstract String startLocalManagementAgent() Starts the local JMX management agent in the target virtual machine. abstract void startManagementAgent(Properties agentProperties) Starts the JMX management agent in the targ...
java官方对于类加载的描述:The Java Virtual Machine starts up by creating an initial class or interface using the bootstrap class loader or a user-defined class loader . The Java Virtual Machine then links the initial class or interface, initializes it, and invokes the public static method void...

virtualMachine.detach(); } } } 首先通过指定的进程ID找到目标JVM,然后通过Attach挂载到目标JVM上,执行加载Agent操作。VirtualMachine的Attach方法就是用来将Agent挂载到目标JVM上去的,而Detach则是将Agent从目标JVM卸载。关于Agent是如何挂载到目标JVM上的具体技术细节,将在下文...
