Abstract: Systems and method for improving query performance by querying an appropriate database engine based on the operation of the query request is provided. In one aspect, this approach involves querying a row-oriented database, querying a column-oriented database, or blacklisting the query request. In particular, updating the column-oriented database involves delete and insert operations. By maintaining updated databases and querying appropriate database engines, the response time of a query request may be improved.

Abstract: A processor may receive a request with a column-oriented operation. The query request may be related to updates to a row-oriented database based on the query request previously performed on the row-oriented database. The processor may determine the amount of time for replicating the updates to a column-oriented database. If the amount of time for replicating the updates to the column-oriented database is greater than a threshold amount of time, then the processor may create a transient file with the updates. The transient file may be in a format that is recognized by the column-oriented database. The processor may query the column-oriented database based on the query request and the transient file.

Abstract: An embodiment may involve persistent storage including a parent filesystem and a pre-configured amount of free space within the parent filesystem that is dedicated for shared use. The embodiment may also involve one or more processors configured to, for each of a plurality of child filesystems: create a sparse file with an apparent size equivalent to the pre-configured amount of free space; create a virtual mapped device associated with the sparse file; establish one or more cryptographic keys for the virtual mapped device; create an encrypted virtual filesystem for the virtual mapped device and within the sparse file, wherein the encrypted virtual filesystem uses the cryptographic keys for application-transparent encryption and decryption of data stored by way of the encrypted virtual filesystem; and mount the encrypted virtual filesystem within the parent filesystem as one of the child filesystems.

Abstract: A database system could include a first database engine, a second database engine, and a replication engine. The database system could also include processors configured to perform operations. The operations could involve obtaining indicators that are respectively associated with performance issues that can occur in the database system, each indicator defining one or more conditions that, when satisfied, cause the indicator to become active. The operations could also involve obtaining mappings between: (i) at least some of the indicators, and (ii) remediation subroutines.

Abstract: A method for authenticating a base station involves a user device sending an authentication request to the base station upon connection to the base station. The authentication request is based on a core network signalling protocol. The user device waits a predetermined amount of time for a response to the authentication request signal and disconnects from the base station if a response is not received or if the response is determined to be inauthentic. The Access Control Class (ACC) of the user device is changed to a different ACC after disconnecting from the base station.

Abstract: A fishing lure includes a body, a plurality of ribs disposed on the outer surface of the body that envelope the body and cover between about 50% and about 100% of the outer surface of the body; and one or more appendages attached to the body. The ribs may cover between about 75% and 95% of the surface area of the body. The ribs may range between about 0.01 and about 0.5 inches wide. The ribs may extend from about 0.01 inches to about 0.5 inches outward from the surface of the body. The ribs may be spaced between about 0.01 inches and 0.1 inches apart. The body may be circular, oval, spheroidal, elliptical, or cylindrical in shape.

Abstract: The present invention relates to a process for producing distilled spirits. After fermentation and distillation, the freshly distilled spirits are placed in wooden barrels and subjected to an initial aging process. Thereafter, the wooden barrels are placed in a tobacco curing and drying barn and aged therein for a selected period of time.

Abstract: A source control system is used for the distributed incremental updating of trays that include all of the dependencies needed for an application to execute within a computing environment. An application of a first version of a tray is executed on a server responsive to the first version of the tray being retrieved from a source control system. Tray management software of the first version of the tray receives a request to update the tray to a second version. The tray management software requests a changeset including file differences between the first and second versions of the tray from the source control system. Responsive to a determination by the tray management software that there are no pending requests preventing an update, the tray is updated from the first version to the second version by updating files in the tray according to the changeset.

Abstract: In an operating system with access control functionality, a request for a function that requires kernel space access can be initiated by an application and executed in the kernel space using a management mechanism having access to the kernel space. An application container within which the application executes includes a signaling mechanism permitted to access a message bus external to the application container using an access control policy of the operating system. The signaling mechanism signals that a message associated with the request is to be processed with kernel space access. An access control policy of the operating system permits the signaling mechanism to access a message bus used to transmit the message to the management mechanism. The management mechanism executes the function in the kernel space responsive to receiving the message from the message bus and determining that the function requires kernel space access.

Abstract: A node of an application instance in a distributed computing environment can be selectively hibernated and the execution of the node selectively restarted by first detecting a condition of the node that satisfies a criterion for hibernating the node. The node may then be hibernated by suspending execution of the node on a server and initiating execution of a listener. The listener can use a network port that the node used before the execution of the node was suspended. At a later time, a request from a client to the application instance can be received by the listener. The request can be a request to restart execution of the node. Responsive to the request and a determination that the server has a predefined amount of resources for permitting execution of the node, the execution of the node on the server can be restarted.

Abstract: The unauthorized access of database nodes by application nodes within an electronic computing and communications system can be prevented using an access table that stores access table records indicating that at least some of the application nodes are authorized to access at least some of the database nodes. The access table records can be generated by identifying connections between application nodes and database nodes within a configuration management database. Responsive to receiving a request to access a database node sent from a first application node, the access table can be queried to determine whether an access table record indicating that the first application node is authorized to access the database node is stored in the access table. If that access table record is not stored in the access table, the request is denied. Otherwise, the request is allowed.
