Abstract

Methods and apparatuses enable in-memory patching of a program loaded in volatile memory. A service processor identifies a program to be patched and an associated patch for the program. The patch is loaded into memory, including applying relocation fix-ups to the patch. The service processor directs the program to the patch in place of the segment of the program to be patched. The program implements the patch while maintaining program state, and without suspending execution of the program.
