Abstract
An apparatus and method are provided for on-line code replacement of a program running in a process. The apparatus and method utilizes a variant of the exec system call, which will be referred to as a text-only exec. The present invention, utilizing a checkpoint methodology, allows the programmer maximum flexibility in addressing upgrade/replacement program issues and determines where, when and how the transition to a new version of a program should occur with least impact to the services.
