Narrative:
I was conducting ojti (on job training instruction) and was not paying as close attention as I should have been. A PA34 was southeast-bound VFR at 11;500. Mode C indicated 11;700. I keyed into the frequency to suggest that the PA34 descend at least 500 feet when I saw that traffic that would pass overhead was a heavy aircraft. I was concerned about him encountering the wake turbulence. The aircraft were outside of bravo airspace. A DC10 got an RA to climb and the feeder controller exclaimed that the DC10 thought the aircraft had missed by only 200 feet and was upset. I then realized that my trainee had not done an automated point out to the feeder controller; and the feeder controller had not seen the traffic to issue it to the DC10. Obviously I need to increase my vigilance even at the beginning of the training sessions and not assume that something is done.
