jinfo（Configuration Info for Java）

1. 介绍

位置：jdk\bin

作用：
jinfo的作用是实时地查看和调整虚拟机的各项参数。
使用jps -v 可以查看虚拟机启动时显示指定的参数列表，但是如果想知道未被显示指定的参数的系统默认值，除了去找资料外，就只能使用jinfo的-flag选项进行查询了。

语法：

D:\javasoft\java_soft\jdk\bin>jinfo
Usage:
    jinfo [option] <pid>
        (to connect to running process)
    jinfo [option] <executable <core>
        (to connect to a core file)
    jinfo [option] [server_id@]<remote server IP or hostname>
        (to connect to remote debug server)

where <option> is one of:
    -flag <name>         to print the value of the named VM flag
    -flag [+|-]<name>    to enable or disable the named VM flag
    -flag <name>=<value> to set the named VM flag to the given value
    -flags               to print VM flags
    -sysprops            to print Java system properties
    <no option>          to print both of the above
    -h | -help           to print this help message

D:\javasoft\java_soft\jdk\bin>jinfo -flag 8644
Usage:
    jinfo [option] <pid>
        (to connect to running process)
    jinfo [option] <executable <core>
        (to connect to a core file)
    jinfo [option] [server_id@]<remote server IP or hostname>
        (to connect to remote debug server)

where <option> is one of:
    -flag <name>         to print the value of the named VM flag
    -flag [+|-]<name>    to enable or disable the named VM flag
    -flag <name>=<value> to set the named VM flag to the given value
    -flags               to print VM flags
    -sysprops            to print Java system properties
    <no option>          to print both of the above
    -h | -help           to print this help message

2. 打印所有的jvm标志信息 jinfo -flags pid

在这里插入图片描述

Non-default VM flags: 非默认VM标志
Command line: 命令行中指定的jvm参数

3. 打印指定的jvm参数信息 jinfo -flag InitialHeapSize pid

在这里插入图片描述

4. 启用或者禁用指定的jvm参数 jinfo -flags [+|-]HeapDumpOnOutOfMemoryError pid

我们运行一段程序，下面这段程序vm参数设置为:-Xms5m -Xmx5m,运行过程中会参数OOM，在运行过程中，我们添加vm参数：+HeapDumpOnOutOfMemoryError：发生OOM的时候，让程序打印堆dump文件

public class OOMTest {
    private static final int _1M = 1024 * 1024;
    public static void main(String[] args) throws InterruptedException {
        List<Object> list = new ArrayList<>();
        for (int i = 0; i < 100; i++) {
            TimeUnit.SECONDS.sleep(10);
            list.add(new byte[_1M]);
        }
    }
}
