In theory, what part of the Oracle cluster would be the bottleneck when all database flared up at same time and then came back down at same time?


I'm curious if it's even possible to have a bottleneck (assuming it's not hardware issue) that can affect all the database on all the clusters at the same time


I'm using Oracle 19c RAC database. 19.4.0.0.0, Linux 7 box


The cluster has 3 nodes, and there are 4 databases. So each node as 4 rac instances. It's evenly distrubuted.


What's odd is that when I cancel the offending query on a single database, it relieves the rest of the databases on that cluster.

Howdy, Stranger!
