What is IBM Lock Analyzer for Java?
Java™ has become a major language used for software development and, therefore, the performance of applications written in Java is an important issue. Many of today's Java applications use threads to support concurrent programming. Often, performance issues can be a result of how an application controls these threads, with poor program design sometimes leading to lock contention problems. IBM® Lock Analyzer for Java is a tool designed to perform lock analysis on a live application in order to highlight threads with lock contention that could affect performance.
How does it work? IBM Lock Analyzer for Java is a tool consisting of two packages. The first package is platform-dependant and provides a connection to the Java virtual machine (JVM) for gathering lock statistics on the running application. This package gets loaded at run time along with the application to be monitored. The second package is not platform-dependant and provides a graphical user interface. The graphical user interface connects to the platform package and provides the controls and analysis required for identifying badly performing locks.
