摘要： A method for predictively allocating space in a database system includes detecting an access request for a data set, evaluating a growth rate of the data set to determine a predicted increase in size of the data set, and in response dynamically altering an attribute of an allocation for the data set. Attributes altered include the size of volumes and the number of volumes comprising the data set. The method may include setting a flag indicating an instruction to rewrite the data set if the evaluation indicates that rewriting is needed to accommodate the predicted increase in size. The method may include rewriting the data set from a lower address space of a volume to a higher address space of the volume if the size of the data set is equal to or greater than an allocation increment of the upper address space. A corresponding apparatus and computer program product are also disclosed herein.

摘要： An approach to selectively recording trace data. The approach sifts through process control and state data to store data that is most relevant to aiding debugging while reducing the overall amount of data that is stored in a trace data set by a trace facility. The approach may involve initiating a trace operation for the software component and, for each resource of the software component, determining whether the resource is currently in use. For those resources in use, the current state of the resource is compared with the previous state of the resource. If the current state has changed, the current state is written to the trace data set. If the resource is not in use, or the current state has not changed, no entry is made to the trace data set. The approach may also analyze users to determine which resources the users are holding and/or waiting for.

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： 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： An abnormal termination recovery is performed where storage is referenced shortly after the storage has been freed. More specifically, when storage is freed, and that storage is accessed, an abnormal termination error (e.g., a page translation exception event) occurs due to referencing storage that has not been obtained. When the abnormal termination error occurs, an abnormal termination recovery operation is accessed. The abnormal termination recovery operation scans a history of storage freeing operations (e.g., FREEMAIN operations) to determine whether the storage location accessed by the storage access that caused the abnormal termination error was recently freed from within the same address space. If the storage location was recently freed, then the abnormal termination recovery operation reverses the storage freeing operation by issuing a storage obtaining operation (e.g., a GETMAIN operation) to re-obtain the storage.

摘要： Various embodiments for defragmentation of a storage volume in a computing storage environment by a processor device are provided. A volume table of contents (VTOC) is serialized for a volume scan operation. At least one dummy data set in the storage volume is allocated, to be subsequently filled with actual data pursuant to a defragmentation operation. The serialization of the VTOC is released, allowing access to the storage volume. Input/output (I/O) operations are allowed to occur.
