Then in another place it says you can switch the backup server back to secondary. (Yes Art, I have told them to change the manual and they will one day). The trick I found to get this to work is that you dontdick with the secondary. As soon as the primary machine is ready and before you start online on primary you do: onmode -d secondary (server_name) on the secondary. It will then log that it is waiting to connect to the primary. Then you start informix on the primary. All chages in the logs will be transfered from the secondary back to the primary. NOTE: This does not work if the log position on the primary is not exactly the same as when you allowed update on the secondary. In that case you get the "server type incompatible" message. This is test on 7.14 NCR and 7.23 HP.
