Abstract:
1. An infrastructure for a computing system that has at least one computing node (“C-node”) for running at least one application program; said infrastructure being for guarding the system against failure, and comprising: at least one monitoring node (“M-node”) for monitoring the condition of the at least one C-node by waiting for an error signal, indicating incipient such failure, from the at least one C-node and responding to the error signal by sending a recovery command to the at least one C-node; at least one adapter node (“A-node”) for transmitting the error signal and recovery command between the at least one C-node and at least one M-node; and wherein: at least one self-checking node for startup, shutdown and survival (“S3-node”), specifically for executing power-on and power-off sequences for such system and for the infrastructure, and for receiving error signals and sending recovery commands to the at least one M-node.
