Mainframe virtualization

摘要

Request data is identified that describes a request of a second program by a first program intercepted by a first exit in the first program. Response data is identified that describes a response by the second program to the request as intercepted by a second exit in the first program. A virtual service configured to model operation of the second program is instantiated based on the request data and response data. In another aspect, a request by the first program to the second program is intercepted by the first exit and the request is redirected to the virtual service. A response is received as generated by the virtual service and the response is returned to the first program using the second exit.

主权项

1. A method comprising:
monitoring, at an agent, data to be sent from a first program in a first region of a mainframe computer to a second program in a second region of the mainframe computer, wherein the data comprises a portion of a transaction and the transaction is to comprise a request and a response, and the agent corresponds to an exit of the first program; generating transaction data based on the monitoring, wherein the transaction data describes attributes of the portion of the transaction; and providing the transaction data for use in generating a service model, wherein the service model is configured for use in instantiating a virtual service to generate simulated responses of the second program.
