摘要:
A method and apparatus are provided for assigning tasks in a distributed system. The method comprises indicating to one or more remote systems in the distributed system that a task is available for processing based on a list identifying the one or more remote systems. The method further comprises receiving at least one response from the one or more remote systems capable of performing the task based on the indication. The method comprises allowing at least one of the remote systems to perform the task based on the at least one received response.

Methods, systems, and apparatus for migrating a database of a workflow processing system from a current version to a new version by serializing the data into serialized objects and then deserializing the objects into the new version of the database. The current version of the database may include elements of data associated with base features and extension features of the workflow processing system. The new version of the database is initially generated to include only base features associated with a new version of the programmed instructions of the system. Deserializing the serialized objects into the new version of the database is effective to merge the object types of the information in the current version of the database into the object type of the new version of the database.
摘要:
A customer record is generated to include fields specifying at least one product, customer preferences, and a selected delivery option indicating a method to deliver generated output material on the product. A job record including a status field is added to a job status table and set to a first status. A first worker is invoked if the selected job has the first status to generate output material from processing the product and customer preference fields in the customer record for the selected job. The status for the selected job in the job status table is set to a second status after generating the output material with the first worker. A second worker is invoked if the selected job has the second status to determine whether a selected one of a plurality of delivery options from the customer record for the selected job and transmits the output material via the determined delivery option to the customer specified in the customer record.
摘要:
A coupling device formed from a first coupling member and a second coupling member with a clamping structure for axially clamping the coupling members. At least three prismatic pins project from the first coupling member each of which is provided with at least one prismatic surface at at least one of the sides of the prismatic pin, and wherein three spaced z-reference surfaces are formed from the first coupling member which extend within a common x-y-plane transverse to the clamping direction. At least three grooves are formed in the second coupling member which are disposed in correspondence to the position of the prismatic pins and which are provided with axially elastic elements for exact positioning the coupling members relative to each other within the x-y-plane. The z-reference surfaces are formed from the free end surfaces of the prismatic pins and z-counter reference surfaces are formed from the base of each groove.
