Hi listers,
how and when are memory areas like DB cache and shared pool being resized, when
the instance runs in Automatic Shared Memory Management?
In my case, I have a system that has had some shared pool eating (child cursor
issue, blowing up the library cache), which was resolved. Now we have a
de-facto undersized buffer cache and low library cache consumption, but I can't
see any resizing taking place. I have SGA max size = SGA Target and no minimum
values for any component here.
Platform: Linux, Oracle EE 12.2.0.1
It would not be a big problem to restart the instance at some point, but this
may be different for other cases. So my interest is more educational. :)
In short: Where are the thresholds, what does trigger the resizing, how often
is it scanned, when does it happen?
Thanks in advance!
