摘要： Methods that can parallel search a partitioned data set extended (PSDE) indexes are provided. One method includes managing a set of quick indexes in a memory device in which the set of quick indexes include references to storage locations for a subset of members of a PDSE stored in a set of long-term storage devices. The method further includes receiving a request to determine a storage location of a member of the PDSE and, in response to the request, searching the set of quick indexes to determine the storage location. Systems and computer program products for performing the above method are also provided.

摘要： Provided are a computer program product, system, and method for an application to provide for, in one embodiment, using hierarchical storage management to respond to a request to delete a data set by migrating the data set to another storage tier in a storage system before deleting the data set from its current location. As a result, the data set is stored on another tier to provide an opportunity to reverse the decision to delete the data set. In one embodiment, a temporary interval of time is provided to reverse the deletion decision and restore the data set from the migrated data set, before the data set is permanently deleted.

摘要： Provided are a computer program product, system, and method for generating node access information for a transaction accessing nodes of a data set index. Pages in the memory are allocated to internal nodes and leaf nodes of a tree data structure representing all or a portion of a data set index for the data set. A transaction is processed with respect to the data set that involves accessing the internal and leaf nodes in the tree data structure, wherein the transaction comprises a read or write operation. Node access information is generated in transaction information, for accessed nodes comprising nodes in the tree data structure accessed as part of processing the transaction. The node access information includes a pointer to the page allocated to the accessed node prior to the transaction in response to the node being modified during the transaction.

摘要： Provided are a computer program product, system, and method for granting and revoking supplemental memory allocation requests. Supplemental memory allocations of memory resources are granted to applications following initial memory allocations of the memory resources to the applications. In response to determining that available memory resources have fallen below an availability threshold, determining a weighting factor for each supplemental memory allocation based on at least one of an amount of the memory resources allocated to the supplemental memory allocation and a measured duration during which the memory resources have been allocated. At least one of the supplemental memory allocations is selected to revoke based on the determined weighting factors of the supplemental memory allocations.

摘要： Provided are a computer program product, system, and method for selecting pages implementing leaf nodes and internal nodes of a data set index for reuse in memory. Pages in the memory are allocated to internal nodes and leaf nodes of a tree data structure representing all or a portion of a data set index for the data set. At least at least one duration parameter indicates an amount of time after which an unused page implement one of the internal nodes or leaf nodes is eligible for reuse. Selection is made of at least one selected page allocated to at least one of the leaf nodes and the internal nodes that has not been used for one of the at least one duration parameter for reuse.
