摘要： A method, apparatus, and computer program product for optimizing the organization of volume records stored in a volume record data set is disclosed herein. In certain embodiments, a method may include monitoring a volume comprising multiple data sets. Each data set may have associated therewith a volume record stored in a volume record data set. The method may further include tracking read and write operations to each of the data sets over a period of time. A count value may be stored in the volume record of each data set. The count value may be increased each time a read operation is performed to the associated data set. The count value may be decreased each time a write operation is performed to the associated data set. The volume records in the volume record data set may then be reorganized according to the size of the count values.

摘要： A plurality of data sets is maintained, wherein each data set comprises an index block and a plurality of data blocks. An index block size is determined for redefining the plurality of data sets, based on an amount of space left unused in index blocks of the plurality of data sets, wherein for determining the index block size greater weight is provided to those index blocks with lesser unused space in comparison to those index blocks with greater unused space. A data block size is determined based on whether the plurality of data blocks is used more frequently for direct processing or used more frequently for sequential processing.

摘要： An apparatus, system, and method are disclosed for resolving computing resource deadlocks. In one embodiment, the present invention includes detecting a set of deadlocked processes within a set of executing processes, cancelling a lowest priority process of the set of deadlocked processes, generating a requested resources report for the set of executing processes, and enabling a user to assign a priority level to a process. In one embodiment, resolving computing resource deadlocks will efficiently detect deadlocks by using a report already generated by the operating system detailing information about allocated resources. By analyzing the resources report to gain information regarding executing processes, deadlocks may be easily determined and remedied. Resolving computing resource deadlocks may be conducted by a utility or it may run as a service of the operating system.

摘要： A method for optimizing a plurality of volume records stored in cache may include monitoring a volume including multiple data sets, wherein each data set is associated with a volume record, and each volume record is stored in a volume record data set. The method may include tracking read and write operations to each of the data sets over a period of time. The method may further include reorganizing the volume records in the volume record data set such that volume records for data sets with a larger number of read operations relative to write operations are grouped together, and volume records for data sets with a smaller number of read operations relative to write operation are grouped together. A corresponding apparatus and computer program product are also disclosed.

摘要： Provided are a method, system, and article of manufacture to manage storage resources in a storage system. Requests by processing systems are received for access to a control block providing information on an address assigned to one of the storage resources to access. A token is generated for each processing system requesting the control block uniquely identifying the processing system and the control block. The processing systems are provided copies of the requested control blocks to use to access the storage resource. A request is received to modify one of the control blocks for one of the storage resources. A determination is made as to whether at least one of the tokens was generated for the control block to modify.

摘要： A method for reorganizing a catalog to improve I/O performance includes initially placing a shared lock on a source catalog. The method then makes a point-in-time copy of the source catalog to generate a target catalog. Once the target catalog is generated, the method reorganizes the contents of the target catalog. Optionally, while reorganizing the contents of the target catalog, the method temporarily releases the shared lock on the source catalog and mirrors I/O intended for the source catalog to a buffer. The buffered I/O may then be used to update the target catalog to bring it current with the source catalog. When the target catalog is reorganized and up-to-date, the method upgrades the shared lock on the source catalog to an exclusive lock, overwrites the source catalog with the target catalog, and releases the exclusive lock. A corresponding apparatus and computer program product are also disclosed and claimed herein.
