摘要:
A system, method and computer program product for directing data backups with flexible timing of data backups based on the importance of the data and on the dynamic nature of the data content. Specifically, a Data Backup Timing (DBT) utility directs granular data backups by implementing the functions of monitoring data updates, revising data parameter values, and by conducting analyses using data parameter values. The DBT utility manages data back-up by automatically performing a back-up of data based on the following criteria: (1) the changes a data file undergoes; (2) whether a particular field has been modified; and (3) how critical the application data is as determined by the application owner. The DBT utility uses these criteria to provide a well timed data backup decision.

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.

A computer-implemented method for test case result processing includes receiving, by a test case result processing logic in a processor of a computer, a test result from a test case that executes on the computer; determining, by the test case result processing logic based on a result description file, whether a result description corresponding to the received result exists in the result description file; based on the result description corresponding to the received result existing in the result description file, determining an action description associated with the result description based on an action definition file; and executing an action corresponding to the determined action description.

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.

In one embodiment, a system includes a critical partitioned dataset extended (PDSE) stored to memory of the system; logic adapted for protecting the critical PDSE by creating a copy of the critical PDSE, referred to as a PDSE copy; logic adapted for providing a critical dataset redundancy (CDR) task with exclusive access to the PDSE copy; logic adapted for providing a replacement critical PDSE by redirecting corralled connections to the PDSE copy; logic adapted for protecting the replacement critical PDSE by creating a copy of the replacement critical PDSE, referred to as a replacement PDSE copy; and logic adapted for providing the CDR task with exclusive access to the replacement PDSE copy.

Various embodiments for optimizing data migration and recall in a computing storage environment by a processor device are provided. Data stored in the computing storage environment is analyzed over a predetermined period of time to identify a usage pattern of a portion of the data. The portion of the data having the usage pattern is recalled in advance of a usage time, the usage time predicted by the usage pattern for the portion of the data to be accessed.
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.

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.

A method for dynamically synchronizing storage groups in a data replication environment is disclosed. In one embodiment, such a method includes detecting the addition of a volume to a storage group of a primary storage system. The method then automatically performs the following in response to detecting the addition of the volume: (1) adds a corresponding volume to a corresponding storage group on a secondary storage system; (2) creates a mirroring relationship between the volume added to the primary storage system and the volume added to the secondary storage system; and (3) adds the mirroring relationship to a mirroring session established between the storage groups on the primary and secondary storage systems. A corresponding system and computer program product are also disclosed.
