Tailoring diagnostic information specific to current activity of multiple threads within a computer system. A request to dump system state is received. A system dump is created, including main memory and system state information. The system dump is stored to a database. In response to a request to format the system dump, the system dump is loaded from the database, whereby a virtual memory image of system state at system dump time is created. The virtual memory image and system state information is scanned to identify tasks that were running, tasks that have failed due to an error, and tasks that were suspended at system dump time. State information and control blocks associated with the identified tasks are collected from the system dump and collated based on task number. The database is updated with a formatted system dump, including the state information and control blocks associated with the identified tasks.

Tailoring diagnostic information in a multithreaded environment

Techniques are provided for executing, by one or more first processors, one or more software products associated with a measured usage pricing model. An indication is received, during the execution of the software products, to execute a set of diagnostic machine instructions related to the execution of the software products. Responsive to that received indication, the one or more first processors initiate execution, by one or more distinct second processors, of the set of diagnostic machine instructions. The initiating of the execution by the distinct second processors of that set of diagnostic machine instructions is based at least in part on such execution not being associated with the measured usage pricing model.

Method and system to decrease measured usage license charges for diagnostic data collection

Techniques are provided for executing a software product that includes a plurality of machine instructions and that is associated with a measured usage pricing model. The executing of the software product includes tracking the usage of one or more computing resources for executing the software product in accordance with the associated measured pricing model. The executing also includes, for each of multiple sets of machine instructions, determining whether the set is associated with a token indicating that the set is a set of diagnostic machine instructions related to the executing of the software product. For each of those multiple sets of machine instructions, the executing of the software product further includes, responsive to a determination that the set of machine instructions is associated with the token, not tracking the usage of the one or more computing resources during execution of that set of diagnostic machine instructions.

The invention provides for customer information control system (CICS) workload management in performance of computer processing tasks based upon 'target' processors requesting work from 'routers', by providing for a target process(or) to first initiate a request to a router seeking distribution of processing task(s) before a new task is assigned by the router to that target for completion.
