JMAP

网络释义：内存图；地图系统

网络释义

1.内存图内存图(jmap)参见jmap -histo选项jconsole或jmap与jhat参见jmap -dump选项Finalizerjconsolejmap -dump与jhat死锁jconsole堆 …

2.地图系统与地图系统(JMAP)结合

1.I've tried it with a busy application using 17GB of Heap memory and jmap was able to produced its histogram in about one minute.我曾经试过检测一个运行频繁并且占用17GB堆内存的程序，使用jmap能够在1分钟内生成程序的性能统计图。

2.The options you'll pass to jmap consist of the name of the file to dump to and whether to use a text file or binary file.您要传递给jmap的选项包括转储文件的名称以及是否使用一个文本文件或二进制文件。

3.Luckily the JVM comes out-of-the-box with the ability to do so, with the built-in tool 'jmap'.幸好JVM内置了工具“jmap”，让它天生就能完成这种任务。

4.For a more casual glance at the Java heap, jmap also supports a -histo option.随意看一下Java堆的更多信息，jmap同样支持-histo选项。

5.The jmap command-line utility prints memory-related statistics for a running VM or core file.jmap命令行工具为运行中的VM或核心文件打印与内存有关的统计信息。

6.To print out a memory histogram, we will invoke the jmap console app passing in our application's PID and the "-histo: live" option .为了打印内存统计图，我们需要打开jmap控制台程序，并输入程序的PID和“-histo：live”选项。

7.Simply point jmap at the VMID of the Java process you want to snapshot, and give it some parameters to describe the resulting file produced.将jmap指向您希望拍快照的Java进程的VMID，然后给予它部分参数，用来描述产生的结果文件。

8.Using jmap is straightforward, like all the other utilities described here.与这里描述的其他所有实用程序一样，使用jmap非常简单。

9.On HotSpot-based runtimes, Memory Analyzer generates the dump using jmap.在基于HotSpot的运行时环境中，MemoryAnalyzer会使用jmap生成这个转储文件。

10.The jmap tool is useful in diagnosing excessive use of finalizers, which can result in an OutOfMemoryError.jmap工具可检测出是否过度使用了完成器，后者可导致出现OutOfMemoryError错误。
