Systems and methods to manage database data are provided. A particular method includes automatically identifying a plurality of storage devices. The storage devices include a first device of a first type and a second device of a second type. The first type includes a solid state memory device. The method may further identify a high priority data set of the database. A rebalancing operation is conducted that includes moving the high priority data set to the solid state memory device and substantially evening distribution of other data of the database among the storage devices.

Methods and systems for selective encryption and secured extent quota management for storage servers in cloud computing are provided. A method includes associating at least one secure storage disk and at least one non-secure storage disk to a virtual disk, and associating the virtual disk to an application to allow access of the at least one secure storage disk and the at least one non-secure storage disk. The method further includes accessing the at least one secure storage disk and the at least one non-secure storage disk based on the associating of the virtual disk to the application, to write or read confidential and non-confidential data associated with the application into a respective one of the at least one secure storage disk and the at least one non-secure storage disk.

A method, a system, and a computer program product are provided for reducing message passing for contention detection in distributed SIP server environments. The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to determine that a first site is waiting for a first object locked by a second site. The programming instructions are further operable to determine that a third site is waiting for a second object locked by the first site, and to send a first probe to the second site to determine whether the second site is waiting. A second probe is received and indicates that a site is waiting for an object locked by the first site. The second probe further indicates a deadlock in a distributed server environment to be resolved.

Methods for reducing power consumption and power leakage in hybrid storage clusters is provided. More specifically, the method is for allocating an appropriate server amongst a plurality of servers in a network by identifying an application to be executed in a network, wherein the network comprises a plurality of servers configured to execute the applications, and each server further comprising a hybrid memory system; based on the application to be executed, dynamically identifying resources to execute the application based on the hybrid memory system available and the power consumption for executing the application; and dynamically allocating the application to the identified resource for execution.

Operational management of a multi-media system includes assessing end user performance with respect to operation of a multi-media device in the multi-media system. Upon determining a performance value derived from assessment of the end user performance exceeds a pre-defined threshold value, the operational management further includes identifying accommodation options that specify modifications to the operation of the multi-media device and/or operations of another multi-media device in the multi-media system that is engaged in a media activity concurrent with the end user of the multi-media device.

The present invention includes a computer-implemented method including, classifying a data set in response to metadata corresponding to one or more data files located on a single database; and creating a data file topology comprising a data file identifier, a data file location and a data file type. The method may also include receiving a predetermined rule directory comprising a set of features corresponding to one or more file systems; and in response to the data file topology and the predetermined rule directory, reorganizing the data set such that at least a portion of the data set is moved to one of a set of new file systems having a predetermined optimized characteristic.

Aspects of the invention provide for automatically selecting optimal fetch settings for business processes as a function of database query load and relational context by monitoring usage of a data retrieval point with respect to a defined unit of work. A multilayer feed-forward neural network is used to predict, as a function of training sets composed of historical data generated by the monitored usage of the data retrieval point, a future value of a data size of results from an eager fetch setting for the data retrieval point. The eager fetch is automatically revised to a lazy fetch setting in response to determining that the future data size value of the eager fetch setting results is larger than a permissible memory resource threshold.

Optimal persistence of a business process

A method, computer system, and computer program product for managing copies of data objects in a network data processing system. The computer system identifies copies of a data object stored on storage devices. The computer system places the storage devices into groups. Each storage device in a group has a smallest distance from the storage device to a center location for the group as compared to distances to center locations for other groups within the groups. The computer system selects a portion of the copies of the data object for removal from the storage devices based on a management of power for the storage devices such that remaining set of storage devices in each group is capable of handling concurrent requests that have been made historically for the copies of the data object. The computer system removes the portion of the copies of the data object from the storage devices.

De-duplicating data in a network with power management

Database tables can have different types of database indices defined for the database tables and different numbers of database indices. The efficiency of reading the indexes can vary with the different profiles of the indexes, which impacts the costs of access plans that use the indexes. Weights can be predefined to reflect the relative efficiencies of the different characteristics. Costs can be computed in accordance with a variety techniques (e.g., based on edge traversals). The weights can be predefined to reduce costs, increase costs, or a combination thereof. A database management application or associated application or program can also refine or revise these weights based on statistical data gathered about the operation of the database and/or heuristics that are developed based on observations/research. The corresponding weights can be adjusted accordingly.

Database index profile based weights for cost computation

Virtual file system virtual nodes are grouped in subpools in response to identified resource components and managed as a function of their subpool groupings. Virtual nodes are decomposed into individual components linked to each other within each node. The components that have repetitive accesses by applications within the virtual file system and their respective frequencies of repetitive access are identified. Modules of linked occurrences of the repetitive components within each of the plurality of virtual nodes are formed, and subsets of the virtual nodes sharing common modules are grouped into subpools. Accordingly, in response to an application of the virtual file system requesting a service that is satisfied by a subpool common module, selection of a virtual node for reinitiating for reuse by the application is restricted to virtual nodes within the subpool associated with the common module.

Virtual node subpool management

A method of operating a cooling system for a hardware component is disclosed. The cooling system comprises one or more cooling devices and the method comprising the steps of monitoring commands that result in one or more operations for the hardware component, detecting a command that will result in a processing intensive operation for the hardware component, and operating a cooling device to cool the hardware component, in response to the detected operation. In a preferred embodiment, following the detection of a command that will result in a processing intensive operation for the hardware component, a predefined profile for the specific operation is accessed, and the operation of the cooling device to cool the hardware component, in response to the detected operation, comprises operating the cooling device according to predefined profile. The profile can be created automatically following previous operations.
