Narrative:
Descending over san francisco heading 130 degrees, numerous vectors given and step down altitudes. Finally given last vector heading to intercept localizer for visual approach to 30L at sjc but previous vector had us too close to localizer hence went through approximately 1 mi northeast of localizer and into oncoming sebound small aircraft with TCASII RA to pull up. We promptly did climb and saw intruder on our 2 O'clock position at our altitude as we continued our left turn back to the localizer. 'RA' on TCASII was only 5-10 seconds in duration. In fairness to the TRACON controller, he was extremely busy but very pushy toward previous air carrier to accept a visual even though pilot protested he did not have traffic visually to follow. More common than not, we face light aircraft in approach corridors that are impossible to see or even identify with radar controller callouts. Solution: further separation of mix and match aircraft.

Title: POTENTIAL CONFLICT RESOLVED BY TCASII RA DURING APCH RADAR VECTORING. ALTDEV ALT EXCURSION.
Narrative: DSNDING OVER SAN FRANCISCO HDG 130 DEGS, NUMEROUS VECTORS GIVEN AND STEP DOWN ALTS. FINALLY GIVEN LAST VECTOR HDG TO INTERCEPT LOC FOR VISUAL APCH TO 30L AT SJC BUT PREVIOUS VECTOR HAD US TOO CLOSE TO LOC HENCE WENT THROUGH APPROX 1 MI NE OF LOC AND INTO ONCOMING SEBOUND SMA WITH TCASII RA TO PULL UP. WE PROMPTLY DID CLB AND SAW INTRUDER ON OUR 2 O'CLOCK POS AT OUR ALT AS WE CONTINUED OUR L TURN BACK TO THE LOC. 'RA' ON TCASII WAS ONLY 5-10 SECONDS IN DURATION. IN FAIRNESS TO THE TRACON CTLR, HE WAS EXTREMELY BUSY BUT VERY PUSHY TOWARD PREVIOUS ACR TO ACCEPT A VISUAL EVEN THOUGH PLT PROTESTED HE DID NOT HAVE TFC VISUALLY TO FOLLOW. MORE COMMON THAN NOT, WE FACE LIGHT ACFT IN APCH CORRIDORS THAT ARE IMPOSSIBLE TO SEE OR EVEN IDENT WITH RADAR CTLR CALLOUTS. SOLUTION: FURTHER SEPARATION OF MIX AND MATCH ACFT.
