摘要:
An upgrade procedure for an application system without downtime is presented. The upgrade procedure includes a mix of a rolling upgrade of application servers, shadow systems, and record and replay mechanisms that employ transformation and locking, for the upgrade of the applications on the application system. Application servers are upgraded one after another. A target version of the system is simultaneously added to the original system and a shadow, or target, system. Data changes are not only carried out in the original system, but are also carried out in the target system, so that a customer realizes no downtime for their data requests to the applications.

摘要:
The invention is a transfer arrangement for transporting and/or positioning and/or aligning a workpiece and is used in particular in presses or press lines. A cross member can be moved and/or pivoted in a plurality of directions in space. The movement of the cross member is controlled or regulated by means of a control unit and by means of a corresponding number of axial drives. A servomotor is located on the cross member. A base support can be coupled to the cross member and a drivable shaft is arranged on the base support. A coupling arrangement of the cross member interacts with a mating connecting means on the base support to establish the mechanical fastening. A coupling means interacts with a mating coupling means to establish a rotational connection between the servomotor and the drivable shaft. A workpiece gripping arrangement is present on the base support.
