Yes, if you know the database application is going to use 70% of your system RAM and you wish to discount that from its memory use when being considered for oom kill, set its /proc/pid/oom_score_adj to -700.
This is only possible on 2.6.36 and later kernels when oom_score_adj was introduced.
If you'd like to completely disable oom killing, set /proc/pid/oom_score_adj to -1000.
