YourKit Java Profiler is a CPU and memory profiler that makes it easy to solve wide range of CPU- and memory-related performance problems. It features automatic leak detection, powerful tools for the analysis of memory distribution, an object heap browser, comprehensive memory tests as part of your JUnit testing process, extremely low profiling overhead, transparent deobfuscation support, and integration with Eclipse, JBuilder, IntelliJ IDEA, NetBeans, and JDeveloper IDEs.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
The goal of dzo is to treat application database objects the same way the application's source code is treated, with respect to development, revision control, and deployment. Dzo uses a text file that contains native create statements for all database objects and compares them against the actual database-schema. As a result, dzo creates the SQL statements needed to update the database schema (or you can let dzo execute the SQL statements directly). If your application lives in a Tomcat or Java EE application server, dzo has a servlet that controls the deployment process, inspects and executes the necessary database changes, and finally deploys the application. Dzo currently works with HSQLDB, MySQL, Oracle, PostgreSQL, and SQL Server (more to come).
