Well, there’s been a bit of a delay in with my planned testing of dbVisit Replicate and Oracle GoldenGate for zero-downtime upgrades. So, I’ll be (hopefully) getting back to that within a couple of weeks.
Meanwhile, I recently ran across a discussion on the Oracle OTN Community forums, asking about performance and hugepages configuration, here in the Oracle Database – General Questions Forum.
I think my answer bears repeating, so, here is a slightly modified version:
First, I’m going to take a strong position on hugepages. I’m going to go as far as to say, for any non-trivial SGA size, if you’re not using hugepages, you’re doing it wrong. There are three main points to consider.
