snapshot dump

基本解釋

Obtaining a snapshot dump: IBM runtimes
獲取一個(gè)快照轉(zhuǎn)儲(chǔ)文件：IBM 運(yùn)行時(shí)環(huán)境
A heap dump, also known as heap snapshot, is a dump of references between objects in memory and information about these objects.
堆轉(zhuǎn)儲(chǔ)也稱為堆快照，就是內(nèi)存中對(duì)象之間的參照轉(zhuǎn)儲(chǔ)，以及關(guān)于這些對(duì)象的信息。
Running this command tells the JVM to take a "heap dump snapshot" and save it to a file for processing, usually using the jhat utility (which I introduced in a previous article).
運(yùn)行該命令通知 JVM 拍攝一個(gè) “堆轉(zhuǎn)儲(chǔ)快照”，并將其保存在一個(gè)文件中以便處理，通常使用 jhat 實(shí)用工具（我在上一篇文章中介紹過(guò)）。
