Determining overall message status in a message processing system

A system for determining an overall message status in a message processing computer system, the system comprising

• one or more computer processors having associated memory, said one or more computer processors being configured to perform:
• registering at least one status provider with a central Status Engine after creation of the status provider, wherein the central Status Engine is attached to the overall message;
• receiving, by the central Status Engine, message statuses output by active status providers, wherein the status provider is a message processing component and is the active status provider upon registration with the central Status Engine, the active status providers being adapted to output message statuses for respective runtime component instances, wherein each of the message statuses for the respective runtime component instance contributes to the overall message status, the active status providers and runtime component instances executing on said one or more computer processors having associated memory, the message statuses being from a defined set of message statuses, each of the message statuses in the defined set having a designated priority;
• determining, by the central Status Engine, a quantity of active status providers and based on the determined quantity:
• determining, if there are no active status providers, that the overall message status is to remain equal to an old overall message status,
• determining, if there is only one active status provider, an intermediate calculated status which is equal to a message status of the one active status provider, and
• determining, if there are more than one active status providers, an intermediate calculated status which is equal to a highest priority message status among message statuses of said more than one active status providers,
• determining an overall status based at least in part on the intermediate status;
• and
• returning the determined overall status to the runtime component instance.

A non-transitory computer-readable medium storing program instructions executed by one or more processors of a computer system having memory, the medium comprising instructions for causing the one or more processors to perform:

• registering at least one status provider with a central Status Engine after creation of the status provider, wherein the central Status Engine is attached to the overall message;
• receiving, by the central Status Engine running on a processor, message statuses output by active status providers, wherein the status provider is a message processing component and is the active status provider upon registration with the central Status Engine, the active status providers being adapted to output message statuses for respective runtime component instances, wherein each of the message statuses for the respective runtime component instance contributes to the overall message status, the active status providers and runtime component instances executing on one or more computer processors having associated memory, the message statuses being from a defined set of message statuses, each of the message statuses in the defined set having a designated priority;
• determining, by the central Status Engine, a quantity of active status providers and based on the determined quantity:
• determining, if there are no active status providers, that the overall message status is to remain equal to an old overall message status,
• determining, if there is only one active status provider, an intermediate calculated status which is equal to a message status of the one active status provider, and
• determining, if there are more than one active status providers, an intermediate calculated status which is equal to a highest priority message status among message statuses of said more than one active status providers,
• determining an overall status based at least in part on the intermediate status;
• and
• returning the determined overall status to the runtime component instance.
