Narrative:
On departure from oakland with first officer flying; and just after initial check-in with norcal control; we received a TA; which was quickly followed by an RA (to maintain vertical speed). Since runway 11 was in use at oakland and we were flying the marina 4 SID; my first instinct after the aural TA was that the traffic must be in the pattern at hayward airport. A scan of the pfd indicated traffic in that area; but the problem bogie that was spotted amber; then quickly turned red; with the one to the front right of our aircraft; a heavy jet off san francisco. The RA announced; 'maintain vertical climb!' as the WX was marginal in most quadrants I made quick note that the first officer was following the proper instructions for the RA then located visually the traffic out the right side of our aircraft. It was greatly decreasing in distance and slightly changing bearing along with a steady altitude that allowed us to avoid each other since we were maintaining our climb. The crew in the other plane seemed a bit perturbed with the controller in communications at that point and following; and stated at their frequency change that they were going to file a report. Their vectoring caused them to pass behind our aircraft but on an easterly course in the general direction that we were also turned. We were switched to another controller shortly after; and in communication with the controller before leaving the frequency; I informed them that we had an RA in the process of the departure and passing traffic.

Title: MD11 FLT CREW HAS A TCAS RA DURING DEP FROM OAK AND MAINTAINS TCAS PRESCRIBED MANEUVERS.
Narrative: ON DEP FROM OAKLAND WITH FO FLYING; AND JUST AFTER INITIAL CHK-IN WITH NORCAL CTL; WE RECEIVED A TA; WHICH WAS QUICKLY FOLLOWED BY AN RA (TO MAINTAIN VERT SPD). SINCE RWY 11 WAS IN USE AT OAKLAND AND WE WERE FLYING THE MARINA 4 SID; MY FIRST INSTINCT AFTER THE AURAL TA WAS THAT THE TFC MUST BE IN THE PATTERN AT HAYWARD ARPT. A SCAN OF THE PFD INDICATED TFC IN THAT AREA; BUT THE PROB BOGIE THAT WAS SPOTTED AMBER; THEN QUICKLY TURNED RED; WITH THE ONE TO THE FRONT RIGHT OF OUR ACFT; A HVY JET OFF SAN FRANCISCO. THE RA ANNOUNCED; 'MAINTAIN VERT CLB!' AS THE WX WAS MARGINAL IN MOST QUADRANTS I MADE QUICK NOTE THAT THE FO WAS FOLLOWING THE PROPER INSTRUCTIONS FOR THE RA THEN LOCATED VISUALLY THE TFC OUT THE R SIDE OF OUR ACFT. IT WAS GREATLY DECREASING IN DISTANCE AND SLIGHTLY CHANGING BEARING ALONG WITH A STEADY ALT THAT ALLOWED US TO AVOID EACH OTHER SINCE WE WERE MAINTAINING OUR CLB. THE CREW IN THE OTHER PLANE SEEMED A BIT PERTURBED WITH THE CTLR IN COMS AT THAT POINT AND FOLLOWING; AND STATED AT THEIR FREQ CHANGE THAT THEY WERE GOING TO FILE A RPT. THEIR VECTORING CAUSED THEM TO PASS BEHIND OUR ACFT BUT ON AN EASTERLY COURSE IN THE GENERAL DIRECTION THAT WE WERE ALSO TURNED. WE WERE SWITCHED TO ANOTHER CTLR SHORTLY AFTER; AND IN COM WITH THE CTLR BEFORE LEAVING THE FREQ; I INFORMED THEM THAT WE HAD AN RA IN THE PROCESS OF THE DEP AND PASSING TFC.
