We need to have high availability over 2 servers. Pls. let us know how we can achieve clustering on SAS Version 9.4 . As per my understanding clustering is possible in SAS Version 9.4.
You need to start off by coming up with a cluster design. What SAS servers are you going to cluster? You would probably start by clustering the SAS metadata server, as there would be no point in clustering other SAS servers without doing the metadata server.
