Has anyone else had a problem with AMM and ebs 12.2? I discovered recently that our AMM was not functioning. It had created a very small db_cache (30% of memory) and a really large PGA. It seems stuck and doesn't fluctuate anymore either and we have a poor cache hit ratio. I am going to switch back to manual management, but another DBA mentioned he'd seen this before and I was wondering if this is a thing. I didn't see any hits on the support site, and I am running with a fully patched 188.8.131.52 system. By that I mean the latest PSU and a clean run for ETCC.
Anyone else see this before, or is it just me?
