Integrating jprofiler into eclipse

问题 I can't integrate jprofiler 7 into Eclipse Indigo. Installation and integration completed successfully. But I can't find jprofiler in the Eclipse IDE or in Eclipse preference. No problems in starting jprofiler, but it's just missing in my Eclipse installation. Thanks :-) 回答1: The "Profile" actions in eclipse are part of the eclipse infrastructure, they are not supplied by JProfiler. I assume that the menu item Run->Profile ... does not exist in the Java perspective after you have run the

What is 'JNI Global reference'

问题 I am using jProfiler to find memory leaks in a Java swing application. I have identified instances of a JFrame which keeps growing in count. This frame is opened, and then closed. Using jProfiler, and viewing the Paths to GC Root there is only one reference, 'JNI Global reference'. What does this mean? Why is it hanging on to each instance of the frame? 回答1: Wikipedia has a good overview of Java Native Interface, essentially it allows communication between Java and native operating system

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言： 因业务需要，在双11来临之际需要对多个业务核心接口做压测工作，话不多说，直接记录（以下记录为本人的切实感受，不代表任何立场，如有出入请另行百度，本人只做比较，方便日后回顾，谢谢） 个人从以下几个角度进行阐述和总结： 1、压测常识 2、服务器性能监控范围 3、脚本编写与压测策略 4、压测实战 5、压测结果查看与分析 6、异常问题定位与分析 7、服务器性能监控 8、JVM监控 9、测试报告 10、踩过的坑 一、压测常识： 负载测试： 通过逐步加压的方法，达到既定的性能阈值的目标，阈值的设定应是小于某个值，如 cpu 使用率小于等于 80% 压力测试： 通过逐步加压的方法，使得系统的某些资源达到饱和，甚至失效的状态，简单粗暴的解释就是什么条件能把系统压崩溃 并发测试： 在同一时间內，多个虚拟用户在同时访问同一个模块，同一个功能，通常的测试方法就是设置集合点 容量测试： 通常是指数据库层面的，目标是获取数据库的最佳容量能力。又称为容量预估。具体测试方法为在一定的并发用户，不同的技术数据量下，观察数据库的处理能力，即获取数据库的各项性能指标 可靠性测试： 又称为稳定性测试或疲劳测试。是指系统在高压情况下，长时间的运行是否稳定。 如 cpu 使用率在 80% 以上， 7*24 小时的运行，系统是否稳定 异常测试：

问题 I am trying to connect Jprofiler7 to remote weblogic10.3 managed servers. I am able to connect and see admin console threads and memory usage in JProfiler but not for application deployed on managed server. How can i achieve this? Thanks 回答1: I had the same problem with WebLogic 12C on windows with JProfiler9 and solved it as follows: Allow JProfiler to create startWebLogic_jprofiler.cmd by profiling WebLogic 12C, but don't attach the profiler at this point. Edit startManagedWebLogic.cmd and

How much memory does jProfiler need to analyze a heap dump of size X?

由 孤者浪人 提交于 2019-12-24 05:38:07
问题 I have a heap size of X (= 5 giga bytes). How much should I allocate for jprofiler to efficiently analyze this heap? 回答1: I would recommend using Eclipse MAT to view the heap dump. It does a much better job in terms of memory requirements for a heap dump of size X because it creates intermediate index files on disk instead of sucking up the whole thing into it's own memory. Most tools require some multiple N of X to open the heap dump where N is usually >= 2. Also, make sure to start the Java

问题 I need to profile an application developed for android platform. I've already used jprofiler in web-application development. I use Android Studio (and Eclipse with ADT plugin) and actually i use DDMS to check cpu and heap memory comsuption. Is it possible to connect Jprofiler to a running application on Android device? 回答1: JProfiler is a tool for profiling applications running on the Java virtual machine. Even though Android uses the Java language, it runs on a different virtual machine, so
