java memory analyzer tool

more memory resources to MAT.One is to modify the startup parameters memoryanalyzer.exe-vmargs-xmx4gThe other is to edit the file Memoryanalyzer.ini, add similar information inside the-vmargs–xmx4g.Description1. The parameters in Memoryanalyzer.ini generally default to-vmargs–xmx1024m, which is sufficient. If your machine memory is not big, change the value of this parameter, will cause Memoryanalyzer star

In addition, there are duplicate classes functions, but also to assist in the analysis of repeated loading of the class, here is no longer, it is certain that Myabsclass was repeatedly loaded n times. Last In fact, the mat tool is very powerful, the above-mentioned example code does not use the other MAT analysis function, so it is no longer described. In fact, for Oom not only I enumerated two kinds of overflow errors, there are a num

Ext.: http://tivan.iteye.com/blog/1487855ObjectiveIn the usual development, testing process, or even production environment, sometimes encountered Outofmemoryerror,java heap overflow, which indicates that the program has serious problems. We need to find the cause of outofmemoryerror. There are generally two situations:1, memory leaks, the object is dead, can not be automatically recycled through the garbag

Summary Although the Java Virtual Machine (JVM) and its garbage collector (garbage COLLECTOR,GC) are responsible for managing most of the memory tasks, a memory leak may still occur in the Java software program. In fact, this is a common problem in large projects. The first step in avoiding a
