Abstract: A method includes receiving a data query instruction for execution, wherein execution of the data query instruction is to cause a data transfer into or from a data warehouse. The data warehouse includes data servers that are communicatively coupled for data transfer through a link aggregation group having at least two data links. Responsive to receiving the data query instruction and prior to or at least partially overlapping with execution of the data query instruction to cause the data transfer, the method includes identifying which of the number of data servers are to receive or transmit data as part of the data transfer; identifying, for each of the identified data servers, a minimum number of the at least two data links that are needed for the data transfer; and activating, if inactive, the minimum number of the at least two data links for each of the identified data servers.

Abstract: A method, computer program product, and system for rebalancing database table space in a hybrid storage environment of heterogeneous storage units used by a plurality of users to store associated extents. The storage units are ranked according to various performance characteristics such as IOPS rates and power consumption, and the users are ranked according to various characteristics such as whether they have subscribed to standard or premium storage subscriptions. Upon detection of a change in the relative ranking of the users or the storage units, the stored extents are mapped, characterized as standard or priority extents, and redistributed across the storage units if needed to provide higher ranked storage for priority extents and for higher ranked users.

Abstract: A method, a system and a computer program of reducing overheads in multiple applications processing are disclosed. The method includes identifying resources interacting with each of the applications from a set of applications and grouping the applications from the set of applications, resulting in at least one application cluster, in response to the identified resources. The method further includes assigning an agent corresponding to each of the identified resources and initializing the agent corresponding to each of the identified resources. The method further includes identifying parameters associated with the identified resources, pre-processing the identified parameters for each of the identified resources, and also includes selecting a clustering means for the clustering. The method further includes computing the application clusters using the selected clustering means and the identified parameters, and also includes sharing the agents corresponding to each of the identified resources interacting with the applications in the at least one application cluster. Also disclosed are a system and a computer program for reducing overheads in multiple applications processing.

Abstract: 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.

Abstract: A method and system for automatically and transparently managing a directory in a database system to preferentially use of objects in an in-memory database instead of copies of the objects in disk-based databases, in order to speed up application response times. The methods and systems selectively add or update LDAP entries to leverage advantage of the database objects in the in-memory database, so that the LDAP entries point to the in-memory database instead of disk-based databases.
