We currently run prod databases (11gr2) on 2 Linux nodes using clusterware. We are planning to add a 3rd node
that will be idle and will be used for up to 10 days/year in case one of the other 2 nodes fail. I'm now looking to protect
the prod databases using data guard at a remote site. Again, we'll have 3 nodes in oracle clusterware with only 2 nodes
active. The 3rd node will be used for up to 10 days/year if one of the other 2 data guard nodes fail. Fail over of
databases at either site is via manual srvctl commands.
Does anyone see any problems with this approach?
I can't find any documentation on how to configure data guard on clusterware, does anyone have a link
I do not see a problem though I do not comment on licensing issues ... check with your Oracle sales rep on that.
Whether one node or 24, whether all active or some passive, you only have one database and Data Guard configuration should not change.
Do not forget you have shared storage and Data Guard runs at the database level not the instance level.
