Hi, I am searching for a Fault Tolerance & Master-master-Replication Solution which fulfills these requirements Req1) Master master replication supported, not only master / slave replication with only the master being writable. If you do have multiple slave systems they are only useful from a backup and standby perspective. Ad Mo must have a db-connection it can write to. Req2) A plan is needed for deploying changes on the database structure. What needs to be done to apply a change saved into a live db environment? Req3) Not only a warm-standby-solution is needed which is not scalable. Load Balancing is wanted for the future. Do you have experience with Cybercluster or Continuent uni/cluster? Sounds very promising. best regards Ragnar ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
