The JDK comprises various key components, including: Java Compiler: This tool translates your human-readable Java code into bytecode that the Java Virtual Machine (JVM) can execute. Java Runtime Environment (JRE): It’s an integral part of JDK, enabling the execution of Java applications. JRE...
3. 收集日志 为了追踪应用的状态和性能问题,需要在启动JVM时配置GC日志。可以在启动参数中添加如下内容: -javaagent:/path/to/your/jdk/lib/tools.jar-XX:+PrintGCDetails-XX:+PrintGCDateStamps-Xloggc:gc.log 1. 这将生成一个gc.log文件,记录垃圾收集的详细信息。 4. 使用分析工具 在此步骤中,我们使用Visua...

Full GC(Full Garbage Collection)是Java虚拟机(JVM)中的一种完全垃圾回收操作。与Minor GC只清理新生代(Young Generation)相比,Full GC会清理整个堆内存,包括新生代和老年代。Full GC通常是在新生代和老年代都需要进行垃圾回收时触发的。 Full GC的目标是回收所有未使用的对象,以释放内存空间并减少堆内存的使用。

JVM is not container aware, and always guesses about the memory resource (for JDK version earlier than 8u131 or 9). Many tools (such as free, vmstat, top) were invented before the existence of cgroups, thus they have no clue about the resources limits. -XX:MaxRAMFraction: maximum ...
