Narrative:
Our flight was cleared on the SUNSS5 arrival and to cross bball intersection at 11000 ft. ATC was also talking to a cessna skylane over the bball area at 12500 ft with parachute jumpers. As we passed 14000 ft, ATC instructed us to level off at 13000 ft, which was accomplished. Shortly after leveling off at 13000 ft, the TCASII gave an RA activation to climb. We climbed to 13400 ft and the cessna passed under us on the right side at 13200 ft according to TCASII. The first officer observed the aircraft passing about 200 ft below and about 600 ft to the right. After clearing the traffic, we received instructions to continue descent to 8000 ft. ATC was told of our RA maneuver.

Narrative: OUR FLT WAS CLRED ON THE SUNSS5 ARR AND TO CROSS BBALL INTXN AT 11000 FT. ATC WAS ALSO TALKING TO A CESSNA SKYLANE OVER THE BBALL AREA AT 12500 FT WITH PARACHUTE JUMPERS. AS WE PASSED 14000 FT, ATC INSTRUCTED US TO LEVEL OFF AT 13000 FT, WHICH WAS ACCOMPLISHED. SHORTLY AFTER LEVELING OFF AT 13000 FT, THE TCASII GAVE AN RA ACTIVATION TO CLB. WE CLBED TO 13400 FT AND THE CESSNA PASSED UNDER US ON THE R SIDE AT 13200 FT ACCORDING TO TCASII. THE FO OBSERVED THE ACFT PASSING ABOUT 200 FT BELOW AND ABOUT 600 FT TO THE R.
