OverviewFor large JAVA applications, fine testing is also hard to block all vulnerabilities, even though we have done a lot of good work during the testing phase, many problems are exposed in the production environment and are difficult to reproduce in a test environment. The JVM is able to record some of the operational state of the system when the problem occurs and store it in a heap dump file, providing an important basis for us to analyze and diagnose the problem.Often memory leak analysis

I like to think of the tools bundled with SQL servers as inverted pyramid. tools for diagnosing and checking general problems are at the top, and tools for finding and diagnosing specific areas of problems are at the bottom.
