Abstract: A system and methods for applications to use a plurality of messaging services with a mainframe system is provided. The system and methods can involve receiving requests via a client application interface (API) coupled to the mainframe system to consume or publish data by the applications and determining by the client application API a messaging service to be used. The system and methods can also involve converting the received requests into a process based on the messaging service to be used and a configuration that is based on the client application API's determination of which messaging service is to be used, and transmitting via a server application interface (API) coupled to the mainframe system the converted received requests to endpoints as defined by the requests.

Abstract: A method for monitoring and predicting batch activity in real time comprises obtaining i) ordered lists of jobs from scheduling platforms and ii) information related to jobs from one or more file transfer sources including real time event information, extracting data from the ordered lists of jobs and file transfer information, enriching the extracted data using additional information retrieved from at least one meta data repository, and generating a dependency graph that includes real time job and file transfer data obtained from the enriched data in which nodes of the graph represent events and edges represent relationships between the nodes indicating a dependence. Critical milestones are obtained from the dependency graph, critical paths for traversing the dependency graph for job and file transfer execution, and times for execution of each of the jobs and file transfers in the critical paths are predicted in real time.
