Abstract:
A computer message processor for protecting database processing messages during a termination and restart, comprising:a message reader for reading input messages; A an in-process message queue coupled to said message reader, receiving a copy of each said read input message; a completion response detector coupled to said in-process message queue, monitoring a valid completion response message to each said read input message, and, upon detecting said valid completion response message, deleting said copied input message from said in-process message queue; and a startup processor coupled to said message reader, responsive to a startup signal for restarting said computer message processor after a termination, operating said message reader to read said copied input messages from said in-process message queue, and, in response to said restarting said computer message processor and said reading said copied input messages in said in-process message queue, deleting each said copied input message that has been read from said in-process message queue by said startup processor, whereby said deletion thereby prevents said accessing of said copied input message upon a second said restart.
