Narrative:

Was issued a visual approach clearance for runway 18L at tulsa. First officer was flying aircraft and turned onto final approximately 4 mi out at 1200-1400 ft AGL. Tower advised us that an small transport would be on approach for runway 18R. Very shortly thereafter, TCASII issued an RA to monitor vertical speed and indicated a further descent. I saw the small transport through the first officer overhead eyebrow windows descending toward us. The TCASII continued the RA and the small transport came to within 300 ft according to the readout on the TCASII. We executed a 45 degree left turn to provide separation and then a missed approach.
