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.

Processing operator message commands

Executing a start operator message command

Transmitting operator message commands to a coupling facility

Managing operator message buffers in a coupling facility

Test tool logic and testing methods are provided for facilitating testing a duplexed computer function, such as a duplexed coupling facility. The test tool allows a testcase written for a first environment to be automatically driven in a second environment, thereby facilitating testing of a function of the second environment. Other aspects include logic for intercepting a system event by a test tool to facilitate testing of system-managed event processing, and for adjusting a display characteristic of one or more messages to be displayed by the test tool based on message type. Further, logic for propagating an environmental error indication and for facilitating processing a wait state are also provided, as are several new test tool verbs and macros.
