摘要： Various technologies and techniques are disclosed for using contracts in dynamic languages. For example, a contract can be directly associated with an object. The contract can then be used to provide type safety for the object. As another example, contracts can be used with mix-ins. A declaration for a contract is provided with a mix-in. The contract is associated with a target object at runtime when applying the mix-in. Conditions can be assigned to mix-ins that must be met before the mix-in can be applied to the target object. At runtime, if the target object meets the one or more conditions, then the mix-in can be applied to the target object.

摘要： Data can be categorized into facts, information, hypothesis, and directives. Activities that generate certain categories of data based on other categories of data through the application of knowledge which can be categorized into classifications, assessments, resolutions, and enactments. Activities can be driven by a Classification-Assessment-Resolution-Enactment (CARE) control engine. The CARE control and these categorizations can be used to enhance a multitude of systems, for example diagnostic system, such as through historical record keeping, machine learning, and automation. Such a diagnostic system can include a system that forecasts computing system failures based on the application of knowledge to system vital signs such as thread or stack segment intensity and memory heap usage. These vital signs are facts that can be classified to produce information such as memory leaks, convoy effects, or other problems. Classification can involve the automatic generation of classes, states, observations, predictions, norms, objectives, and the processing of sample intervals having irregular durations.

摘要： A computer method and system dynamically provide consistency of Java application files. A processor executed routine is configured (e.g., instrumented as an agent) to intercept each class that is loaded into a subject Java application or JVM. The system computes a cyclic redundancy check (CRC) of the respective JAR file surrounding the loaded class. The system compares the computed CRC value to a CRC value of at least one other copy of the respective JAR file. Based on results of the comparison, the system determines consistency (e.g., same version) of the multiple copies of the respective JAR file used by the subject Java application. If the multiple copies of the respective JAR file are determined to be inconsistent, the system alerts the user and/or enables the application to abort. The comparative CRC value may be stored in a repository; and the step of comparing looks up the stored CRC value in the repository.

摘要： A technique assists in resolving problems by aiding in the determination of the root cause of the problem. The technique allows recording of information about methods of executing applications that encounter problems, even if the method was not previously marked for recording. Upon detection of a problem, the method and all other methods on the current execution stack may be marked for retrospective recording. When each method exits, information about entry conditions and exit conditions of each method may be recorded for presentation to a user of the application for problem resolution.

摘要： A method for monitoring a heap in real-time to assess the performance of a virtual machine. A mobile agent is created to be preloaded with boundary settings for each heap metric. Boundary settings are thresholds that are used to diagnose the effectiveness of operation of the heap. The mobile agent is deployed onto an application server to monitor the effectiveness of operation of the heap of a virtual machine within the application server. If a boundary setting for one of the heap metrics is exceeded, then the mobile agent determines whether a non-critical, a critical or a fatal error has occurred. An appropriate response is then performed. By monitoring the heap in real-time, undesirable behavior characteristics of the heap can be detected early thereby allowing remedial actions to be enacted to address such problems before those problems escalate into more serious problems.

摘要： Various embodiments provide message queue management techniques designed to reduce the likelihood of multi-component applications becoming nonresponsive and enable recovery options for individual components if they do become nonresponsive. In at least some embodiments, a message queue manager detects when a component of an application interface becomes nonresponsive and detaches the component from a shared message queue. The shared message queue can continue to process messages for other responsive components while messaging for the nonresponsive component is managed via a separate queue. The message queue manager can also notify a user regarding the nonresponsive component and provide the user with options to facilitate recovery of the nonresponsive component. Further, in at least some embodiments, the message queue manager can monitor a detached component and reattach the detached component when it becomes responsive again.

摘要： According to a sample embodiment, a method is provided for capturing context information about an event. A data collector is created comprising instructions to collect specific context data in response to specific conditions in a call stack, and the data collector is registered with a first failure data capture application. In a sample embodiment the first failure data capture application receives a registration for a context data collector. Then, in response to being called, the first failure data capture application looks for at least one of a class and a method defined in the context data collection registration that matches conditions of the call stack. In response to said call stack conditions being met, the first failure data capture application calls the data collector to collect context data from the call stack, receives context data from the context data collector; and presents the context data.
