What are the pros/cons for the following options in implementing a
wide-area oracle (e.g. 100-1000 miles apart)?  In terms of cost,
performance and data consistency?



    
  
  1.   Single-site single-server (big!) with remote clients
  
  2.   Single-site multi-servers using RAC with remote clients
  
  3.   Single-site server(s) (option 1 or 2) with advanced replication
onto remote hosts
  
  4.   Multi-site servers with RAC and wide-area SAN






Any comment/suggestion?
