Narrative:

On sep/fri/00, we were flying abcd, a C650, from sjc to cyur. On the climb out from sjc, runway 30, we were given a turn to 360 degrees and climb to 5000 ft. At 3000 ft while still climbing the controller urgently told us to maintain 3000 ft. At the same time we received a TCASII TA. We made an abrupt leveloff. Immediately after we received an RA 'climb, crossing climb.' I followed the vsi command. Immediately after starting the climb we received a 'descend, descend now' command. I followed the command. The first officer reported the TCASII climb. The first officer finally saw the other aircraft fly past our right wing. The other aircraft was talking to the same controller we were talking to, but we couldn't figure out if there was an ATC error, or if the other aircraft was in error. We were told the 360 degree heading was for traffic, but we were never given a traffic position call.

Narrative: ON SEP/FRI/00, WE WERE FLYING ABCD, A C650, FROM SJC TO CYUR. ON THE CLBOUT FROM SJC, RWY 30, WE WERE GIVEN A TURN TO 360 DEGS AND CLB TO 5000 FT. AT 3000 FT WHILE STILL CLBING THE CTLR URGENTLY TOLD US TO MAINTAIN 3000 FT. AT THE SAME TIME WE RECEIVED A TCASII TA. WE MADE AN ABRUPT LEVELOFF. IMMEDIATELY AFTER WE RECEIVED AN RA 'CLB, XING CLB.' I FOLLOWED THE VSI COMMAND. IMMEDIATELY AFTER STARTING THE CLB WE RECEIVED A 'DSND, DSND NOW' COMMAND. I FOLLOWED THE COMMAND. THE FO RPTED THE TCASII CLB. THE FO FINALLY SAW THE OTHER ACFT FLY PAST OUR R WING. THE OTHER ACFT WAS TALKING TO THE SAME CTLR WE WERE TALKING TO, BUT WE COULDN'T FIGURE OUT IF THERE WAS AN ATC ERROR, OR IF THE OTHER ACFT WAS IN ERROR. WE WERE TOLD THE 360 DEG HDG WAS FOR TFC, BUT WE WERE NEVER GIVEN A TFC POS CALL.
