Program code update recommendation based on a heatmap

A computer program product for recommending an application of a software code update, the computer program product comprising:

• one or more non-transitory computer readable storage media and program instructions stored on the one or more non-transitory computer readable storage media, the program instructions comprising:
• program instructions to receive components of an executable program;
• program instructions to scan the components to divide the executable program into units;
• program instructions to create a logical layer of entry lists, based on the units, for instantiations of the executable program;
• program instructions to load the instantiations of the executable program based on the logical layer;
• program instructions to monitor execution of the instantiations to increment counters based on executions of the units;
• program instructions to create a heatmap of executions based on the counters;
• and
• program instructions to generate a recommendation to update the executable program based on the heatmap.
