Network Partition in Two Node Cluster
If one node in a two-node SDM cluster becomes non-operational, the non-operational node tries to recover and rejoin the cluster. However, if this node is non-operational for more than 24 hours, use this task to restore the two-node cluster.
Note:
With the introduction of Oracle Communications Session Delivery Manager, Release 8.0, you must select one server to start in the cluster only. Once this server is started and operational, you can start the other server(s) in the cluster. When connectivity between nodes is re-established automatically or manually, the Berkley XML database decides which node becomes the master.
