Abstract
A program replacing method is provided for an uninterruptible online computer system. The computer system includes an auxiliary storage unit for storing a program currently running in the computer system and another program to replace the current running program and a replacement request managing table for storing replacement requests and program IDs of such replacing programs. These programs include checkpoints pre-programmed at selected locations therein. At an optional checkpoint, the replacement request managing table is retrieved for checking whether or not the replacement is requested. If a replacement is requested, the new program is started according to the program ID and the current program is terminated.
