jdk命令行工具系列(3) - jinfo:jvm配置信息工具

jinfo(Configuration Info for Java)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。

[root@localhost ~]# 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

jinfo -flag <pid>:打印所有的jvm标志信息

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

jinfo -flag <name> <pid>: 打印指定的jvm参数信息

[root@localhost ~]# jinfo -flag InitialHeapSize 113595
-XX:InitialHeapSize=522190848

jinfo -flag [+|-] <name> <pid> :启用或者禁用指定的jvm参数

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 Test7 {
    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 < 10; i++) {
            TimeUnit.SECONDS.sleep(3);
            list.add(new byte[_1M]);
        }
    }
}

运行过程中添加参数
