Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, system objects, devices (such as printers) and service-oriented networks. Those resources are represented by objects called MBeans (for Managed Bean ).
In other cases resource leaks can be a major problem, causing resource starvation and severe system slowdown or instability, crashing the leaking process, other processes, or even the system. [2] Resource leaks often go unnoticed under light load and short runtimes, and these problems only manifest themselves under heavy system load or systems ...
A continuous inspection engine that finds vulnerabilities, bugs and code smells. Also tracks code complexity, unit test coverage and duplication. Offers branch analysis and C/C++/Objective-C support via commercial licenses. SourceMeter: 2016-12-16 (8.2) No; proprietary — C, C++ Java — — Python RPG IV (AS/400)
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
The "sawtooth" pattern of memory utilization: the sudden drop in used memory is a candidate symptom for a memory leak. If the memory leak is in the kernel, the operating system itself will likely fail. Computers without sophisticated memory management, such as embedded systems, may also completely fail from a persistent memory leak.
Check the return value of all non-void functions, or cast to void to indicate the return value is useless. Use the preprocessor sparingly. Limit pointer use to a single dereference, and do not use function pointers. Compile with all possible warnings active; all warnings should then be addressed before release of the software.
In Java, a composite object (class A which uses instances of B and C) is created using references to allocated instances of B and C. In C++ the memory and performance cost of these types of references can be avoided when the instance of B and/or C exists within A.
The Jakarta Transactions (JTA; formerly Java Transaction API), one of the Jakarta EE APIs, enables distributed transactions to be done across multiple X/Open XA resources in a Java environment. JTA was a specification developed under the Java Community Process as JSR 907.
