10g RAC on Red Hat AS 3.0 using CRS (Cluster Ready Services)
I've was under the impression that RAC was supposed to be able to handle network failures. Now that I go back and look, I don't see this discussed in detail within the documentation. Rather, there are hints, such as:
http://www.oracle.com/technology/products/oracle9i/datasheets/rac/rac_rel2_ds.html
"Through introduction of quorum disk, network failure and node failure are detected and resolved faster, resulting in faster completion of cluster reconfiguration."
My testing shows that if a network failure takes place to one node, all nodes are frozen and basically the concept of high availability is not on the radar; no new connetions to any node and current connections to alternate nodes are locked up and end with a 3113 error.
Have others had success in making RAC highly available during network failures? Maybe this is a function of not using an OS based cluster solution. "Anyone know what this is? Class? Anyone? Anyone? anyone seen this before."
An almost complete tar indicates that this is a bug that would be treated as a new feature request and NOT something that would happen in 10g if ever.
