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： A data structure maintained in a computational device stores how many control areas splits have occurred to store a data set, wherein each control area split causes an addition of a single new control area. A command is received to add a new data record to the data set. A determination is made as to whether adding the new data record to the data set will result in a threshold for control area splits to be exceeded. In response to determining that adding the new data record to the data set will result in the threshold for control area splits to be exceeded, creating at least two new control areas in addition to continuing to use one existing control area for storing the data set.

摘要： Described are embodiments of an invention for allocating storage space in a storage system for critical data sets. The computing environment includes at least one server including a processor and memory. The server is coupled to storage. The memory further includes a storage manager including an allocation module and an alert module. The storage manager defines a common area for storing non-critical data sets and critical data sets in the storage group. The storage manager also defines a critical reserve area for storing only critical data sets in the first storage group. A predefined percentage of available storage space is reserved for the critical reserve area. The predefined percentage of available space is determined by comparing the available storage space within the critical reserve area to the storage space in the storage group. Upon allocating additional storage to the storage group, the allocation module allocates an amount of the additional storage space to the critical reserve area such that the predefined percentage of available storage space is maintained in the critical reserve area.

摘要： A directory and members are allocated to store a data set, wherein the directory stores pointers to the members to allow data stored in the members to be accessed. The directory is expanded to accommodate an expansion of the data set, causing the directory to be stored in non-contiguous pages and becoming fragmented. A computational device determines that a threshold that measures a level of fragmentation of the directory relative to an amount of storage allocated for the data set has been exceeded. The computational device reorganizes the fragmented directory, into a reorganized directory that is stored in contiguous pages at the end of the data set, in response to determining that the threshold has been exceeded.

摘要： Provided are a computer program product, system and method for updating class assignments for data sets during a recall operation in a storage environment having a plurality of storage devices. Information on a data set is processed to determine at least one current attribute of the data set. A determination is made as to whether the determined at least one current attribute satisfies a criteria. Indication is made in a catalog to change a class associated with the data set in response to determining that the at least one current attribute satisfies the criteria, wherein the class is used to determine how to manage the data set. The data set is migrated from a first storage to a second storage. A recall operation is initiated to recall the data set from the second storage. In response to the recall operation and determining that the catalog indicates to change the class associated with the data set, the catalog is processed to determine whether to change the class for the data set from a first class to a second class and a management operation is performed on the data set to conform the data set to the second class when recalling the data set.

摘要： A central hub is coupled to a plurality of computational devices. The central hub stores a data structure that grants locks for accessing common data stored at the central hub, wherein the common data is shared by the plurality of computational devices. Each computational device maintains locally those locks that are held by the computational device in the data structure stored at the central hub. In response to a failure of the data structure stored at the central hub, a selected computational device of the plurality of computational devices is determined to be a manager system. Other computational devices besides the manager system communicate to the manager system all locks held by the other computational devices in the data structure stored at the central hub. The data structure and the common data are generated and stored at the manager system. Transactions are performed with respect to the data structure stored at the manager system, until the data structure stored at the central hub is operational.

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.
