Módulo de recuperación de fallos de los procesos de un sistema FreeBSD utilizando variables en disco
Journal Title: MASKANA - Year 2017, Vol 8, Issue 2
Abstract
This paper describes the creation of a crash-recovery module of the processes in a reliable communication program with fall and recovery of equipment, on a FreeBSD system. The creation of this module is based on the parameters or values that a running process contains, establishing a variable or file that is stored on disk. The variable is synchronized with the values of each process so that they can be retrieved by the module, avoiding loss of information during the transmission prior to the data integration. The module presents two recovery mechanisms, the coherence checker and the concurrency control, each of which process in a synchronized way with the process and the recovery of the variable in the event of a failure.
