Does anyone know what this wait (wait for scn from all nodes) is about
in RAC. We are currently running a test on a two-node RAC/11i instance.
Statspack is showing this wait among the top five (at #5). We are using
the "broadcast on commit" scheme as it is recommended by Oracle for 11i
instances. Per Metalink, this event is related to the broadcast scheme
that we are using. But what does it really mean and at what point it
becomes a matter of concern? Any feedback will be appreciated.
Thank you
Amir
