Hi, Under Universe/Linux we use Data Replication Block Device. www.drbd.com (open source linux product) A low level software called between logical partition and hdd partition. Cluster over LAN.
We define it on partitions where Universe db is installed (including universe himself). On the hot-standby server, the same partition is created and not mounted (universe is not started ~ for this raison, we don't need IBM's license) On fail-over, we switch the ip adress to the hot-standby server, we mount the partition, we boot uv and users can work ... 2 minutes. One restriction, we don't use DYNAMIC files because the headers are not permanently flushed when write occurs files. Coupled with Universe Transaction Logger set on strategic files to ensure "record update integrity". My two pence.
