Abstract: A query inserter receives data elements having individual priority types for placement in a queue, and utilizes the priority types of the received data elements to determine placement in the queue relative to an initial location established when a first data element is placed in an empty queue in order to manage the queue with a combination of first-in first-out and last-in first-out queue functionality.

Abstract: Freeing memory safely with low performance overhead in a concurrent environment is described. An example method includes creating a reference count for each sub block in a global memory block, and each global memory block includes a plurality of sub blocks aged based on respective allocation time. A reference count for a first sub block is incremented when a thread operates a collection of data items and accesses the first sub block for a first time. Reference counts for the first sub block and a second sub block are lazily updated. Subsequently, the sub blocks are scanned through in the order of their age until a sub block with a non-zero reference count is encountered. Accordingly, one or more sub blocks whose corresponding reference counts are equal to zero are freed safely and with low performance overhead.

Abstract: System, method, computer program product embodiments and combinations and sub-combinations thereof for protection of encryption keys in a database are described herein. An embodiment includes a master key and a dual master key, both of which are used to encrypt encryption keys in a database. To access encrypted data, the master key and dual master key must be supplied to a database server by two separate entities, thus requiring dual control of the master and dual master keys. Furthermore, passwords for the master and dual master keys must be supplied separately and independently, thus requiring split knowledge to access the master and dual master keys. In another embodiment, a master key and a key encryption key derived from a user password is used for dual control. An embodiment also includes supplying the secrets for the master key and dual master key through server-private files.

Abstract: A system and methodology providing workload management in a database cluster. In one embodiment, for example, a method for allocating workload amongst a plurality of database servers sharing access to data comprises steps of: periodically collecting information about workload at each database server; distributing the workload information to each of the plurality of database servers; in response to a client connected to a first database server requesting that work be performed, examining the workload information to determine whether the requested work should be performed at a second database server having a lower workload than the first database server; if it is determined that the work should be performed at the second database server, automatically transferring the client connection to the second database server and performing the requested work at the second database server; and otherwise, performing the requested work at the first database server.

Abstract: A system, method, and computer program product for character data compression for reducing data storage requirements in a database system are described. Embodiments include identifying data of a particular character type in a full data page, and identifying usage frequency of each character of the particular character type. Each character is encoded based on the identified usage frequency and stored, with storage requirements for most frequently used characters are reduced.

Abstract: Methods, systems, and computer program products for cache conflict detection are provided. A computer-implemented method may include providing a partial graph of data to an application executing on a mobile device where the partial graph is derived from a document comprising a graph of data having a plurality of nodes, receiving a modified partial graph from the application where the modified partial graph includes one or more changes to the partial graph, and determining a document version used to derive the partial graph is no longer a most recent version of the document.
