At a cloud platform, a class of feed is received for an external feed corresponding to an information source, as are an instruction corresponding to a create operation for the external feed, and a dictionary input corresponding to parameters expected by the information source. The external feed produces a corresponding class of events. At the cloud platform, a handler is selected based on the received class of feed and the received create operation; the input dictionary is transferred to the handler; and the handler generates a unique destination to receive events for the class of events. The handler on the cloud platform generates a unique request to the information source to generate events of the class of feed to the unique destination and sends the request to the information source. Events generated from the information source responsive to the unique request are received at the unique destination.

Managing external feeds in an event-based computing system

A method of coupling asynchronous process interaction between computer systems integrated within an overall system of interconnected systems includes receiving a set of information describing an invocation call for execution of a first process on a first system integrated within the overall system; correlating a first callback argument received upon completion of the first process that includes a first unique identifier for the first process generated by the first system with the set of information according to the first unique identifier for the first process; and sending a notification message to a callback endpoint in a second process implemented to receive notification upon completion of the first process by the first system indicating completion of the first process. The second process executing on a second system integrated within the overall system makes the invocation call. The set of information specifies the first unique identifier and the callback endpoint.

One aspect of the present invention provides a workflow model to effectively respond to outage events within an IT infrastructure. This workflow model enables a combination of manual and automated processing to effectively deploy a flexible, plannable, and testable recovery to outages and problems encountered within IT infrastructure settings. In one embodiment, a shared processing context is created to accompany the operations of the workflow, thereby collecting useful data in one location related to events and status information during the outage and the outage response. Within the workflow, analysis of the outage event is performed, an appropriate recovery plan is selected, the selected recovery plan is implemented, and recovery to the outage event is completed. Data collected within the processing context can be analyzed to obtain post mortem analysis and continuous service improvements. Accordingly, the improvements can be implemented within the IT infrastructure directly or within the appropriate recovery plan.

A metadata file can be automatically generated based on a database instance and a user defined maximum depth. The relationships between data objects that constitute a business object may be visualized in a tree. The maximum depth limits the number of levels in the tree to traverse. A metadata file describes the structure of a business object and relationships between sets of data objects that constitute the business object. The structure defined in the metadata file can be used to export instances of the business object from the database. The exported business object instances can be imported to another database.
