摘要： A method in a multithreaded computing environment for capturing diagnostic data, the method comprising the steps of: in response to a determination that the computing environment is in a predetermined invalid state, a first thread recording diagnostic data for the computing environment, wherein the determination includes a verification that the invalid state corresponds to a state other than a transient state of the computing environment corresponding to a transition of the computing environment by a second thread from a first valid state to a second valid state. An apparatus and computer program element for providing such diagnostic data capture are also provided.

摘要： A legacy machine-oriented language interface definition of a new module to be implemented within a legacy machine-oriented language application using an object-oriented language is received at a processor. An object-oriented class definition and bridging code that interfaces the object-oriented class definition to the legacy machine-oriented language interface definition is generated by the processor. An updated version of the object-oriented class definition is received that includes object-oriented code that implements functionality of the new module. A new version of the legacy machine-oriented language application is created that includes the new module as a new object accessible using the legacy machine-oriented language interface definition and as implemented by the object-oriented code in the updated version of the object-oriented class definition.

摘要： A software application recreation in a computing environment is provided. One embodiment involves analyzing program execution trace data of a software application, and using the analysis results in recreating an executable version of the software application from data traced at significant points during the software application execution. Recreating an executable version of the software application involves creating white space code to simulate the software application execution timing by replacing business logic code of the software application with white space code in the recreated executable version. The recreated executable version of the software application programmatically behaves essentially similarly to the software application.

摘要： A method and transaction processing system for managing transaction processing tasks are provided. The transaction processing system comprises a transaction log, a log management policy, a log manager and a dispatcher. The method comprises maintaining a transaction log of recoverable changes made by transaction processing tasks and storing a log management policy including at least one log threshold. Usage of the log by transaction processing tasks is then monitored to determine when a log threshold is reached. When a log threshold is reached the active task having the oldest log entry of all active tasks is identified and its dispatching priority is increased. This increases the likelihood that the identified task will be dispatched, and should mean that the task will more quickly reach normal completion.

摘要： A transaction processing system comprising a transaction log, a log management policy, a profile and a log manager, and method for managing the transaction log are provided. The method comprises maintaining a transaction log of recoverable changes made by transaction processing tasks; storing a log management policy including at least one log threshold and a plurality of possible actions associated therewith; and generating a historical profile comprising a set of acceptable values for characteristics of the log resource usage of tasks. Such log resource usage characteristics may include time taken for a task to complete, CPU resource consumed, number of log records made, etc. From a comparison of the profile behaviour to the actual behaviour of a task which has been identified as holding up trimming of the log, the likelihood that the identified task has entered an invalid loop and represents a ‘bad’ transaction instance, rather than simply just taking a long time to complete, can be inferred. Thus the most appropriate action can be selected and taken.
