jinfo

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。

  1. [root@localhost ~]# jinfo
  2. Usage:
  3.     jinfo [option] <pid>
  4.         (to connect to running process)
  5.     jinfo [option] <executable <core>
  6.         (to connect to a core file)
  7.     jinfo [option] [server_id@]<remote server IP or hostname>
  8.         (to connect to remote debug server)
  10. where <option> is one of:
  11.     -flag <name>         to print the value of the named VM flag
  12.     -flag [+|-]<name>    to enable or disable the named VM flag
  13.     -flag <name>=<value> to set the named VM flag to the given value
  14.     -flags               to print VM flags
  15.     -sysprops            to print Java system properties
  16.     <no option>          to print both of the above
  17.     -h | -help           to print this help message

jinfo -flag <pid>：打印所有的jvm标志信息

file

  1. C:\Users\Think>jps -l
  2. 44748 com.jvm.test6.Test
  4. C:\Users\Think>jinfo -flags 44748
  5. Attaching to process ID 44748, please wait...
  6. Debugger attached successfully.
  7. Server compiler detected.
  8. JVM version is 25.121-b13
  9. Non-default VM flags: -XX:CICompilerCount=4 -XX:InitialHeapSize=10485760 -XX:MaxHeapSize=1048576000 -XX:MaxNewSize=349175808 -XX:MinHeapDeltaBytes=524288 -XX:NewSize=3145728 -XX:OldSize=7340032 -XX:+UseCompressedClassPointers -XX:+UseCompressedOops -XX:+UseFastUnorderedTimeStamps -XX:-UseLargePagesIndividualAllocation -XX:+UseParallelGC
  10. Command line:  -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:64223,suspend=y,server=n -Xms10m -Xmx1000m -Dfile.encoding=UTF-8
  • 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

  1. [root@localhost ~]# jinfo -flag InitialHeapSize 113595
  2. -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

  1. public class Test7 {
  2.     private static final int _1M = 1024 * 1024;
  3.     public static void main(String[] args) throws InterruptedException {
  4.         List<Object> list = new ArrayList<>();
  5.         for (int i = 0; i < 10; i++) {
  6.             TimeUnit.SECONDS.sleep(3);
  7.             list.add(new byte[_1M]);
  8.         }
  9.     }
  10. }

运行过程中添加参数

  1. C:\Users\Think>jps -l
  2. 44520 com.jvm.test7.Test7
  4. C:\Users\Think>jinfo -flag +HeapDumpOnOutOfMemoryError 44520
  6. C:\Users\Think>jinfo -flags 44520
  7. Attaching to process ID 44520, please wait...
  8. Debugger attached successfully.
  9. Server compiler detected.
  10. JVM version is 25.121-b13
  11. Non-default VM flags: -XX:CICompilerCount=4 -XX:+HeapDumpOnOutOfMemoryError -XX:InitialHeapSize=6291456 -XX:MaxHeapSize=6291456 -XX:MaxNewSize=2097152 -XX:MinHeapDeltaBytes=524288 -XX:NewSize=2097152 -XX:OldSize=4194304 -XX:+UseCompressedClassPointers -XX:+UseCompressedOops -XX:+UseFastUnorderedTimeStamps -XX:-UseLargePagesIndividualAllocation -XX:+UseParallelGC
  12. Command line:  -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:53193,suspend=y,server=n -Xms5m -Xmx5m -Dfile.encoding=UTF-8

程序运行结果：

  1. Connected to the target VM, address: '127.0.0.1:53193', transport: 'socket'
  2. java.lang.OutOfMemoryError: Java heap space
  3. Dumping heap to java_pid44520.hprof ...
  4. Disconnected from the target VM, address: '127.0.0.1:53193', transport: 'socket'
  5. Heap dump file created [4535342 bytes in 0.009 secs]
  6. Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
  7.     at com.jvm.test7.Test7.main(Test7.java:18)

jinfo -flag <name>=<value> <pid>：给指定的jvm参数设置值

jinfo -sysprops <pid>：打印系统参数信息

打印的信息和System.getProperties()一样。
