Program code update recommendation based on a heatmap
An approach for recommending an application of a software code update. The approach receives components of an executable program. The approach scans the components to divide the executable program into units. The approach creates a logical layer of entry lists, based on the units, for instantiations of the executable program. The approach loads the instantiations of the executable program based on the logical layers. The approach monitors the execution of the instantiations to increment counters based on executions of the units. The approach creates a heatmap of the executions based on the counters. The approach generates a recommendation to update the executable based on the heatmap.
1 . A computer-implemented method for recommending a deployment strategy for deploying a software code update, the computer-implemented method comprising:
receiving, by a pre-loader module at a server computer, a software code update for a target program installed on a client computer, the software code update for updating the target program on the client computer;
scanning, by the pre-loader module, the software code update to identify executable units of the software code update, the executable units being identified by the scan as one of class, function, or module;
creating, in the server computer, a logical layer of entry lists for instantiations of the identified executable units;
loading the instantiations of the identified executable units to system memory from the logical layer of entry lists;
monitoring execution of the instantiations of the identified executable units to increment counters based on observed executions of the instantiations;
