摘要： A method for selectively generating trace data is disclosed. Such a method includes executing a first module on a processor. The processor is operably coupled to a memory storing the first module and one or more branch modules. The method further includes detecting the execution of an instruction of the first module to execute a branch module. In response to detecting execution of the instruction, traces of branch modules subsequently executed by the processor are generated. Upon detecting a return of execution by the processor to the first module, the generation of traces is terminated and a trace report is generated. A corresponding apparatus and computer program product are also disclosed herein.

摘要： An apparatus, system, and method are disclosed for dynamically allocating buffers during the execution of a job. A plan module sets a buffer allocation plan for the job using data access history that contains information about the number and nature of data access events in past executions of the same job. A buffer module allocates buffers during the execution of the job, and alters the buffer allocation to improve performance for direct access events for those portions of the job that the buffer allocation plan indicates have historically included predominantly direct access events. The buffer module alters the buffer allocation to improve performance for sequential access events for those portions of the job that the buffer allocation plan indicates have historically included predominantly sequential access events. A history module then collects data access information about the current execution and adds that information to the data access history.

摘要： A method for automatically optimizing an allocation amount for a data set includes receiving an extend request, specifying an allocation amount, for a data set in a storage pool. The method increments a counter in response to receiving the extend request. In the event the counter has reached a threshold value, the method automatically increases the allocation amount of the extend request, such as by multiplying the allocation amount by a multiplier. In the event the allocation amount is larger than a largest free extent in the storage pool, the method automatically decreases the allocation amount of the extend request to correspond to the largest available free extent. Such a method reduces or eliminates the chance that an extend request will fail, and reduces overhead associated with extending and consolidating extents. A corresponding apparatus and computer program product are also disclosed herein.
