[英]Can I run Java garbage collection against a heap dump file?
I have a huge Java heap dump file. 我有一个巨大的Java堆转储文件。 It also contains (I believe) unreachable objects, that would be garbage collected by the JVM (or so one hopes). 它还包含(我相信)无法访问的对象,这些对象将由JVM垃圾回收(或者有人希望如此)。
Is there a tool that allows me to run the garbage collector against this file, so that I can 是否有工具允许我对此文件运行垃圾收集器,以便我可以
No idea about 2+3 (and I don't think it would be possible) but at least requirement 1 is the default in the Eclipse Memory Analyzer 不知道2 + 3(我认为不可能),但是至少要求1是Eclipse Memory Analyzer中的默认设置
"By default unreachable objects are removed from the heap dump while parsing and will not appear in class histogram, dominator tree, etc" “默认情况下,无法解析的对象在解析时会从堆转储中删除,并且不会出现在类直方图,支配器树等中”
