Abstract
Embodiments describe an approach for improving for improving application upgrade by minimizing blackout time for a single partition kernel. Embodiments send a command to a second core to load a new code load into a second portion of a memory and to execute the new code load, and instruct an old code load, executing on a first core, to save a process state and TCP connection state in a shared memory. Additionally, embodiments, instruct the new code load to read the process state and the TCP connection state from the shared memory, receive a notification from the new code load that the new code load is active and processing client requests, and instruct the old code load to terminate and remove the old code load from a first portion of the memory.
