Ah...you noticed my imprecise language....I'm the alternate DBA for this system. I don't normally work on RAC. I'm talking about Node 1 kicking Node 2 out of the cluster. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Kevin Closson Sent: Monday, June 05, 2006 2:36 PM To: oracle-l@xxxxxxxxxxxxx Subject: RE: Oracle Supported RAC Configuration You can use a zoned switch. What is an "eviction" in your terminology? _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Freeman, Donald Sent: Monday, June 05, 2006 11:26 AM To: oracle-l@xxxxxxxxxxxxx Subject: Oracle Supported RAC Configuration We are having an argument with our CoLo facility over the issue of a dedicated switch for our RAC interconnect. We are saying it's an Oracle requirement and Oracle does not support any other configuration. Of course, I can't find any Metalink source for that requirement. I can't think up any more wild combinations of search terms that will bring me back any fewer than 10k docs. Does anybody have any reference for this "requirement?" We are experiencing periodic evictions from the cluster and wanted to eliminate network issues from our considerations.
