Info

Bonus: Global Buffers • Despite great performance gains from Row Cache over the past couple of years, we still were anticipating issues for our fall busy period • We turned on GB on many Dbs – On our busiest server, we enabled it on all dbs – On other servers, we have about 50% implementation • Used to run with RDM$BIND_BUFFERS of 220 • Estimated GB at max number of users@200 ea
Global Buffers • Prior to implementing GB, our busiest server was running at a constant 6,000- 7,000 IO/sec • Other servers were running around 3,000 but had spikes to 7,000 or more • Global buffers both lowered overall IO, as well as eliminated spikes • Cost is in total Locks (Resources) – Increase LOCKIDTBL and RESHASHTBL
