Hi folks,
I'm trying to troubleshoot why some tables are unloading from memory. When I look at Used Memory/Peak Used I see that used is 29% and peak is 100.8%. So my understanding (correct me if I am wrong) is that at some point the used memory finally reached 100% and so the system uses its secret unload algorithm and proceeded to unload some memory until it dropped to the current 29%. So it looks like I have plenty of memory for the moment. So I go ahead and run a fairly intensive view and immediately I see automatic unloading occurring in M_CS_UNLOADS. It appears used memory is only 29% and I know for a fact that my view does not need all of the other available 71% so I'm not clear on why tables are being unloaded.
NOTE: I notice that resident memory is about 75%. Used memory is about 132gb and resident is 367gb. Could the tables be unloading due to resident memory being so high? If so my next question is; should resident memory be consuming almost 3 times the amount of memory as the used memory?
Thanks,
-Patrick
