I don't think the latency is coming from the OS, but who knows. At this
point the Scheduler (CA Inc) is seeing it in the OCI calls, but that just
means it's downstream from them. Oracle is saying they can't find anything
in the logs, and so I've got a whole lot of shrugging shoulders. The Storage
guys say the OS can tell is they are having resource issues, and the OS guys
are saying they don't see any resources spikes. The only thing I do know is
that no one has a clue. To solve the problem we 'roll around the horn' so to
speak on the RAC environment. Latency disappears after that. it smells like
an Oracle issue, but at this point I'm stuck.
