first, what is Jconsole? Jconsole has been introduced from Java 5. Jconsole is a built-in Java performance Analyzer that can be run from the command line or in a GUI shell. You can easily use Jconsole (or, perhaps, its more high-end "close cousin" VISUALVM) to monitor Java application performance and track code in Java. second, how to start jconsole if it is sta

With SPA, you can play a specific stream based on various types of changes (such as initialization parameter changes, optimizer statistics refresh, and database upgrades)SQL or the entire SQL load, and then generate a comparison report to help you evaluate their impact. In versions earlier than Oracle Database 11g, I must capture all SQL statements and trace and run these statements,Then get the execution plan-this is an extremely time-consuming and error-prone task. In the new version, we don't

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 number of other errors, but I want to say, for P
