Hi,
I have a customer who runs a older Superdome Server with an 8 socket board
(7 sockets used).
End of quarter processing is approaching and we would need some
performance boost.
In theory we should have Numa effects. The hidden parameters for Numa (
"_enable_NUMA_support"
= TRUE according to MOS Doc ID 1956463.1) are not set.
I see a chance to get some quick improvement.
However, Numa is not my topic. I am a bit concerned by the fact that the
newest MOS entry I find dates back to db version 12.1.
Well, these kind of servers are not widely used any more.
Can somebody shed some light on the issue? Is NUMA still an issue in
version 19c?
Can we expect some improvement stetting NUMA support in the db?
Thanks
Lothar
