Hello all!
We have Replicated Data Cluster two nodes in local cluster. No global clustering.
My questions now about our RDC cluster. I could not find all neсessary information in cluster pdf doc.
1. When the primary Site1 fails (or we switch over SAP IP vcs group manually ) the secondary Site2 becomes primary with Site 1 DB going down.
Should the cluster agent start up Site 1 DB as secondary automatically or administrator must do it manually?
2. We must have three different IPs for RDC cluster : one virtual IP is for connections from applications (productive SAP IP)
and two IPs for two nodes for data replication between primary and secondary databases.
But we have no sample RDC cluster configuration with replication IPs. Why? This is strange because cluster must know about network replication status...
3. Is Replicated Data Cluster (RDC) really supported for SAP HANA Cluster Agent ?
Could you give us a real working configuration example?
Thank you very much! Kind regards , Pavel Tsvetkov
