Patent ID: 8140905

Claim:
A method for incremental problem determination and resolution in computer environment, comprising: annotating one or more installation files for checkpoints, the annotating including inserting triggers to have one or more system snapshots taken at one or more points during the execution of the installation files on the system; executing, using a processor, the one or more installation files as a test run and storing a plurality of checkpoint snapshots generated during the test run; attaching error description to a checkpoint snapshot and storing the error description if it is determined that the test run failed as of at a point the checkpoint snapshot is taken, the error description describing one or more of deterministic or non-deterministic factors that caused the test run to fail; executing the one or more installation files as production run; comparing a checkpoint snapshot of the production run with the plurality of checkpoint snapshots generated during the test run; in response to determining that the checkpoint snapshot of the production run matches with one or more of the plurality of checkpoint snapshots generated during the test run, and the matching one or more of the plurality of checkpoint snapshots generated during the test run includes the stored error description, notifying with the stored error description.
