A system and method are provided for indexing and mining content of multiple data sources. The method includes: providing a database of learned content of multiple data sources learned using text analysis, the learned content identifying one or more concepts to which a data source relates, wherein the concepts are cognitively associated with the data source and include concepts not explicitly referenced in the data source and providing an index of the learned content including associations between concepts with mappings between concepts and the multiple data sources. The method further includes receiving input of a query and using text analysis to analyze the query to determine one or more query concepts to which it relates and mining the indexed concepts in response to the query concepts to return a list of referenced data sources.

Indexing and mining content of multiple data sources

A system and method are provided for managing content creation of data sources. The method includes: analyzing content of a data source while simultaneously identifying one or more alternative data sources having similar concepts of the content of the data source, the similar contents based on a degree of similarity between the concepts of the data source and one or more concepts of the one or more alternative data sources. The method further includes providing an indication based on a degree of similarity for performing a defined operation on the one or more alternative data sources in relation to the data source.

Managing content creation of data sources

A method of storing and deleting data maintains a record of backups of the stored data, the record defining an entry for each backup comprising details of the data that has been backed up and the location of the data that has been backed up. The record of backups of the stored data is updated with a new entry every time at least part of the stored data is stored at a new location different from the first location. Once an instruction is received to delete the stored data, the maintained record of backups of the stored data is accessed, and an instruction is transmitted for each respective entry in the record of backups, the instruction comprising an instruction to delete the stored data at the respective location for the respective entry.

Deletion of stored data

Embodiments for managing unequal workloads between Network Shared Disks (NSD) in a networked computing environment by a processor. Additional space may be carved out from at least one of a plurality of NSDs in a cluster file system, upon detecting an unbalanced load between the plurality of NSDs, while maintaining a predetermined level of usage according to a performance profile of the plurality of NSDs.

A computer-implemented method includes accessing documentation and classifying the documentation. The method includes associating the documentation with symbols in a source code index of an integrated development environment. The symbols are of a code base. The method also includes creating annotations to the code base linking the documentation to the symbols associated therewith. A computer program product for an enriched integrated development environment includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer. The program instructions cause the computer to perform the foregoing method. A system includes a processor and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to perform the foregoing method.

Enriched integrated development environments

An embodiment of the invention may include a method, computer program product and computer system for profile picture selection. The method, computer program product and computer system may include a computing device which may classify user photographs in user account data into one or more photograph classifications. The computing device may classify an emotion conveyed by a media interaction by the user and select a classified user photograph matching the emotion conveyed by the media interaction by the user. The computing device may display selected user photograph with the media interaction by the user.

Content based profile picture selection

An incremental backup system that performs the following (not necessarily in the following order): (i) making a plurality of time-ordered journal entries; (ii) determining that a corruption condition exists; (iii) responsive to a corruption condition, constructing a first incremental mirror data set that reflects a backup data set and all journal entries up to a first corrupted journal entry which is the earliest in time journal entry, of the plurality of journal entries, that is a corrupted journal entry; (iv) responsive to a corruption condition, constructing a second incremental mirror data set that reflects the backup data set and all journal entries up to the first corrupted journal entry; and (v) checking for corruption in the first and second incremental mirror data sets to determine the latest uncorrupted version of the data set.

File corruption recovery in concurrent data protection

Various embodiments for management of object-based storage by a processor. A relationship-based analysis of attributes of an object in the storage is performed. A repository of the attributes is maintained, and a modification to the object insofar as any of the attributes change, is tracked. An object-based storage architecture is organized for the object using the attributes and their relationships.

Optimization of object-based storage

Provided are a computer program product, system, and method for selective write control in accordance with the present description. In one aspect, a write operation which is associated with a read operation, may be selectively discarded if write operations have been disabled and if the write operation is directed to update a designated write operation acceptance area such as metadata associated with the target data set, for example. As a result, the read operation may be permitted to proceed and will not fail because the associated write operation was discarded rather than attempting to commit the write operation to the designated write operation acceptance area, thereby avoiding an error condition for a storage unit such as a volume, in which write operations have been disabled. Accordingly, applications which seek to perform read operations may be permitted to access data stored on such a volume. Other aspects are described.

Selective write control

A mechanism is provided in a data processing system for managing filesystem inodes. The mechanism monitors inode consumption in a filesystem. The mechanism periodically determines a number of inodes to add to the filesystem based on the inode consumption and adds the number of inodes to the filesystem.

Managing filesystem inodes

A method for caching reads in a data replication environment is disclosed. In one embodiment, such a method includes receiving a read request at a primary site of a data replication environment. The method executes the read request at the primary site. In the event data associated with the read request is not already cached at the primary site, the method stores the data in cache at the primary site. The method also notifies a secondary site of the read request at the primary site. This notification may be sent synchronously or asynchronously as time and resources allow. In the event the data is not already cached at the secondary site, the method stores the data in cache at the secondary site. A corresponding system and computer program product are also disclosed.

Read caching in PPRC environments

A computer-implemented mechanism is provided that monitors usage of one or more computing resources within a set of computing components relative to a received workload. The mechanism calculates a maximum workload for the set of computing components from the monitored use of the computing resources within the set of computing components and determines an available overhead between the calculated maximum workload for the set of computing components and a current workload being performed by the set of computing components. The mechanism selects one or more maintenance tasks for the set of computing components, the total workload of the selected maintenance tasks being less than the determined available overhead.

Selection of maintenance tasks

Embodiments for scanning data within and between distributed computing components by a processor. Data scanning functionality is allocated through an object storlet located at a local node of the distributed computing components. The data scanning functionality is performed using computational components of the object storlet on local data contained within the local node to alleviate transfer of the local data outside of the local node to be scanned.

Data scanning within distributed computing components

A computer-implemented method, according to one embodiment, includes: determining, using a processor, whether a virtual machine is authorized to run using a data structure having metadata about properties of the virtual machine; determining, using the processor, whether a hypervisor is authorized to run the virtual machine using a digital signature of the data structure; and running the virtual machine on a computer system using the hypervisor in response to determining that the virtual machine is authorized to be run and that the hypervisor is authorized to run the virtual machine. Other systems, methods, and computer program products are described in additional embodiments.
