Narrative:

Air carrier X was cleared for the ILS [runway] xx approach; but was not put on the tower frequency. I did not realize this until air carrier X said he was responding to an RA. I told him it was parallel traffic off his right and [asked if] he wanted to continue the approach. He said yes; so I told him to contact tower. Two miles later he told me he was going around. I told him to climb to 5;000 ft on the localizer and; again; contact the tower.
