摘要： An approach to efficient data reorganization. The approach may involve searching for control interval (CI) splits and control area (CA) splits in a data component of a VSAM data set. A mapping is created that maps the source location storing the VSAM data set to a target location. The mapping reorders the VSAM data set such that the CI splits and CA splits are removed when the VSAM data set is moved to the target location in accordance with the mapping. Those CAs that do not include CI splits may be moved without using the host devices' processing resources. For example, the storage device may FlashCopy these areas directly from the source location to the target location. Those CAs that do include CI splits may be moved using the host's processing resources. For example, these CAs may be read into the host, re-ordered by the host, and written by the host to the target location.

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.

摘要： Method, system, and computer program embodiments for reducing deadlock in multi-system computing environments are provided. A set of default, current wait times is initialized for resource requests of each of a plurality of resources. A plurality of resource holders and resource waiters is monitored within an address space. If one resource holder of the plurality of resource holders of one of the plurality of resources is determined to be one resource waiter on another of the plurality of resources, a current wait time for the one resource holder is incremented and a deadlock indicator for both the one resource holder and the one resource waiter is activated. Following expiration of a predefined interval, the plurality of resource holders and resource waiters are parsed through to determine an original resource holder, indicating a system deadlock. The resource holder associated with the system deadlock having a lowest current wait time is restarted.

摘要： Methods, data structures and systems provide organize a table of contents for a volume (VTOC) stored in a storage system. The volume is divided into a plurality of ranges of tracks, including a first track range. For each track range, an associated sub-VTOC is created containing information about the contents of the track range. A master VTOC is also created containing a plurality of pointers, each pointer pointing to one of the plurality of sub-VTOCs. A first data set stored on one or more tracks within the first track range is updated and the sub-VTOC associated with the first track range is locked, whereby access to other sub-VTOCs is unaffected. The sub-VTOC associated with the first track range may then be accessed, updated and unlocked. Thus, updating data sets stored within different track ranges on the volume may proceed at the same time.

摘要： Provided are a computer program product, system, and method for using an alias volume name for a volume to allocate space to a data set. An assignment of a plurality of volumes to a data set is maintained, wherein the volumes are configured in a storage system. A request is received to extend the data set. A determination is made as to whether one of the volumes previously assigned to the data set has an allocation amount of available space in the storage system in response to the request to extend the data set. An alias volume name is assigned to the data set for the previously assigned volume determined to have the allocation amount of available space, wherein the alias volume name provides an alternative name for the previously assigned volume. The allocation amount of available space is assigned to the data set for the alias volume name.

摘要： Provided are a computer program product, system, and method for recovering a volume table and data sets from a corrupted volume. Data corruption is detected in a volume having data sets. A volume table having information on the data sets allocated in the volume is diagnosed. A backup volume table comprising a most recent valid backup of the volume table is accessed from a backup of the volume in response to determining that the diagnosed volume table is not valid. Content from the backup volume table is processed to bring to a current state in a recovery volume table for a recovery volume. The data sets in the volume are processed to determine whether they are valid. The valid data sets are moved to the recovery volume. A data recovery operation is initiated for the data sets determined not to be valid.

摘要： Various embodiments for adaptive reorganization of a virtual storage access method (VSAM) data set are provided. In one exemplary embodiment, upon each control interval (CI) split of a plurality of CI splits occurring over a period of time, historical data including a key value for a record causing each CI split is recorded in a data repository. The historical data is analyzed with a predictive algorithm to determine an amount of free space to be allocated to each of a plurality of control intervals generated pursuant to the adaptive reorganization. The predictive algorithm allocates a greater percentage of the free space to a first location of the VVDS having a larger proportion of historically placed key values than a second location of the VVDS having a smaller proportion of the historically placed key values.

摘要： A detection module selects logically adjacent first and second control areas of a cluster. The detection module further determines that the first and second control areas satisfy a migration test wherein the first control area has free space exceeding a free threshold, the free space is at least equal to a space requirement for each second control area control interval, and the second control area has fewer control intervals than a control interval threshold. In addition, a copy module copies each second control area control interval to the first control area in response to determining that the first and second control areas satisfy the migration test.
