Abstract: According to some embodiments, a system to manage database management system backups may include a plurality of database services. For each database service, a database backup resource (e.g., a human-readable structured document) may specify desired backup state information (e.g., a buffer size, a schedule, an amount of memory, etc.). A stateless backup operator component may then compare a present backup state of each database service with the associated desired backup state information. When a mismatch is identified between the present backup state of a database service and the associated desired backup state information, that database service may be automatically reconfigured (e.g., in connection with a recover job, backup job, backup configuration job, keystore backup job, etc.) in accordance with the desired backup state information.

Abstract: A system to manage database management system backup objects may include an external storage component storing a first database management system backup object. A database management system node (e.g., associated with a database as a service cluster of a hyper-scalar infrastructure) may be configured to write information to and read information from the external storage component without being able to delete information in the external storage component. A backup housekeeping component, independent of the database management system node, may trigger a request to retrieve backup requirement information (e.g., associated with a maximum backup age, a latest backup identifier, an indication of a newest backup to be deleted, etc.) from the database management system node.

Abstract: A heavy truck tire tread (2) having a longitudinal direction (LgD), a lateral direction (LtD), a tread depth direction (TdD), a ground contact surface (CS) and a pair of opposing tread shoulders (3, 4) spaced apart along the lateral direction is provided. The tread has a shoulder zone (SZ, SZ?) adjacent each tread shoulder of the pair of opposing tread shoulders, the shoulder zones consisting of blocks (5, 6) adjacent to each other along the longitudinal direction and separated by lateral grooves (7, 8). A center zone (CZ) is defined between the shoulder zones. The center zone is decoupled from both shoulder zones by at least one longitudinal sipe (11) or groove, and each lateral groove (7) in a shoulder zone (SZ) is directly connected to an opposite lateral groove (8) in the opposite shoulder zone (SZ?) by a lateral sipe (10) of the center rib.

Abstract: A tower for a wind turbine is disclosed, said wind turbine comprises the tower, a nacelle and a rotor having at least one rotor blade. The tower is configured for supporting the nacelle and the rotor on a support system. The tower itself may be structured as having an upper top end for supporting the nacelle and a lower support end for being placed on the support system. Electric energy generated is transported via power cables from the nacelle to an electric grid, preferably via power electronic components, switches and/or transformers. Furthermore, the nacelle may rotate around the yaw axis according to the current wind direction. Hence, the rotation of the nacelle introduces a twist into the power cables, wherein said twist causes a deviation (shortening) in the length of the power cables. Furthermore, the tower comprises at least one radial cable guiding device for receiving the cable and a cable support arrangement for supporting the cable in a beneficial manner.

Abstract: Described is a system for secure management of recovery data for data protection assets such as backup data and a backup application of a production backup system. The system may provide the ability to synchronize and secure critical recovery data of an isolated recovery environment. Accordingly, the system may reduce the breadth of potential cyber security attack vectors and increase the likelihood of efficiently recovering critical data and/or applications. To provide such capabilities, the system may only activate a data connection between a production system and a recovery system when synchronizing recovery data. In addition, the system may apply a retention lock to maintain a set of immutable copies of the recovery data and may restore the recovery data to a sandboxed environment where it may be tested and verified before being deployed to the production system as part of a recovery process.

Abstract: The invention provides for a heavy truck tire tread (2) having a longitudinal direction, a lateral direction and a thickness direction, said tread having a ground-engaging contact surface (CS) and having a main longitudinal center groove (5), two main longitudinal shoulder grooves (3, 7) and two main longitudinal intermediate grooves (4, 6), said five main longitudinal grooves defining six main longitudinal ribs (8, 9, 10, 11, 12, 13), said five main longitudinal grooves comprising one hidden groove, two open grooves and two partially hidden grooves; wherein each of said two partially hidden grooves comprises openings (41, 61) to the ground-engaging contact surface and undersurface channels (42, 62) connecting adjacent openings, longitudinal sipes (43, 63) extending substantially along the longitudinal direction and connecting successive openings to the respective channel; and wherein said hidden groove (5) comprises an undersurface duct (52), a longitudinal sipe (53) extending substantially along the longitu

Abstract: Replicating a tenant database includes receiving at a source system a first request from a target system for replicating a first tenant database of the source system, which includes one or more first servers. Characteristics of the one or more first servers are sent to the target system to generate at the target system a second tenant database including one or more second servers. Each second server corresponds to one first server and has the same characteristics as the corresponding first server. Information from each first server is replicated, in an asynchronous mode, to the corresponding second server through a communication channel that is established between each first server and the second server. Upon receiving a second request for stopping the replication, a synchronous mode of processing statements from client applications of the first tenant database is entered. Related apparatus, systems, techniques and articles are described.

Abstract: The disclosure generally describes methods, software, and systems for performing automatic backups to the cloud. Application code in a database system updates rows and columns in the database for an updated object, and automatically performs a backup of database information to the cloud. Performing the backup includes directly executing a REST call to the cloud storage solution to which the backup of the database information is performed. Performing the backup includes: sending a request, using a REST call, to create a new object in the cloud storage solution; in response to receiving an acknowledgement of a successful creation of the new object, sending, to the cloud storage solution, REST PUT calls that include contents of the object for the cloud storage solution to store into the created new object; receiving, from the cloud storage solution, a specific key identifying the backup; and locally storing the specific key.
