Procedure; Airspace Structure; Human Factors
I noticed a code of 1202 maneuvering between 16;500 - 17;400 FT in the arrival corridor. I did not observe the code for a few updates; but had called traffic to 2 previous aircraft that descended. I was descending an A319 on top of an aircraft going to ONT. The A319 reported traffic at their altitude. I responded with a traffic call and mistakenly said the glider was going Eastbound. The A319 stated they were responding to an RA and climbing. I reported the traffic was no longer observed and gave the A319 a pilot's discretion to 15;000 FT. I recommend that gliders be able to communicate with air traffic. I also recommend that they have specific areas for gliders to operate that are in less congested areas for safer outcomes.
ZLA Controller described a TCAS RA event apparently triggered by a glider operating close to an Air Carrier descending into ONT; the reporter suggesting that gliders communicate with ATC and be restricted to areas clear of Air Carrier operations.
