Processing operator message commands

摘要

A facility is provided to enable operator message commands from multiple, distinct sources to be provided to a coupling facility of a computing environment for processing. These commands are used, for instance, to perform actions on the coupling facility, and may be received from consoles coupled to the coupling facility, as well as logical partitions or other systems coupled thereto. Responsive to performing the commands, responses are returned to the initiators of the commands.

主权项

1. A computer program product for facilitating processing of operator message commands in a computing environment, said computer program product comprising:
a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
obtaining, by a coupling facility of the computing environment from a source separate from, but coupled to the coupling facility, an operator message command and a token associated with the operator message command, the operator message command to specify, by the source separate from, but coupled to the coupling facility, an action to be taken on the coupling facility to test at least one of reliability and erformance of the coupling facility;using the token associated with the operator message command to provide a buffer of the coupling facility to store the operator message command, the buffer usable in performance of the operator message command, and wherein the buffer comprises a token field for storing the token associated with the operator message command;performing the operator message command, the performing using the buffer; andproviding a response to processing the operator message command, the response to be available to the source of the operator message command.
