Exadata Inter-database low bandwidth

edited Nov 15, 2011 9:48AM in Exadata General (MOSC) 4 commentsAnswered
 Hello,
We have several RAC databases on Exadata V2. All databases have one instance per compute node.
For ILM purpose we transfer large amount of data between these databases via database links.

The bandwidth seams to be limited by the regular network speed. The listeners serve the "public" interfaces only.
I think that the infiniband (private) network is not used during these transfers.

How do you manage this "inter-database" connections on Exadata?

We think about creating a SDP listener on private network using the procedure described in:

Howdy, Stranger!
