Influencing that using the oom_score_adj tunable is exactly the right way to do this as Harald said, from filesystems/proc.txt: "The value of /proc/<pid>/oom_score_adj is added to the badness score before it is used to determine which task to kill. Acceptable values range from -1000 (OOM_SCORE_ADJ_MIN) to +1000 (OOM_SCORE_ADJ_MAX). This allows userspace to polarize the preference for oom killing either by always preferring a certain task or completely disabling it. The lowest possible value, -1000, is equivalent to disabling oom killing entirely for that task since it will always report a badness score of 0." There are other tunables there (see proc.txt and the man page) but this one gets the job done.
