Hi Jay,
You can analyze v$bh to check top consumers of buffer cache.

Yes, index and table blocks. No DDL for quite a while and no large DML
that I’ve been able to uncover.
No memory pool resizing since January 9, 2019.

Hi Jay,
Have you checked what is it reading? Index blocks, table blocks or undo?
Were there any DDL or huge DML operations? Have you checked v$bh? What
about memory settings? AMM/ASMM/manual? Have you checked v$sga_resize_ops?
