Abstract: Systems and methods include presentation of a subset of a result set of items received from a remote system, reception of a command to perform an operation on all items of the result set while presenting the subset, and determination, in response to the command, of whether a total number of items in the result set exceeds a threshold value. If it is determined that the total number of items in the result set exceeds the threshold value, a first request is transmitted to the remote system to perform the operation on all items of the result set, where the first request includes filter values associated with the result set. If it is determined that the total number of items in the result set does not exceed the threshold value, a second request is transmitted to the remote system to perform the operation on all items of the result set, where the second request includes an identifier of each item of the result set.

Abstract: Disclosed herein are system, method, and computer program product embodiments for replicating data from table in a source database to a target database. In some embodiments, data replication includes access plan delimitation and access plan calculation steps and is performed on a table having multiple partitions. A table may be divided into one or more partitions and each partition may be further divided into one or more access plans. Access plan delimitation may involve calculating, in parallel, boundaries of access plans within partitions of the table. Access plan calculation may be initiated on the first partition that has completed the access plan delimitation steps, and may involve transferring data from each delimited partition from the table in the source database to the target database.

Abstract: Methods for detecting faults in a siren-based alert system include receiving, by a siren device from a central siren controller, an activation command. The activation command identifies a neighbor siren device that is to be activated. Audible alerts output by the neighbor siren device include a unique identifying characteristic associated with the neighbor siren device. The method includes determining that the unique identifying characteristic is not detectable by the siren device and, in response, taking corrective action. The corrective action includes the siren device sending a siren fault notification to the central siren controller indicating a failure to detect the unique identifying characteristic and may also include modifying the audible alert output by the siren device to compensate for the faulty siren device. The siren device may send a siren fault notification to the central siren controller if an unexpected audible alert, such as a potential false alarm, is detected.

Abstract: The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.
