Software AG strongly recommends against allowing live migrations of virtual machine(s) with Software AG Terracotta server processes. This is because of the downtime introduced during the live migration process which can cause other Terracotta server processes to elect a new active server which will then create data consistency problems (such as split-brain scenarios) when the migrated process becomes live again.

If you must use vMotion in your environment, please make sure that Terracotta server processes and runtime processes are excluded from live migration. Be very thoughtful about any other VMs that you put on the same hardware - the workload within it may be disruptive to the resources available to the Terracotta server.

Applications utilizing Terracotta (Terracotta clients) can also experience disruption by live migrations - although they will normally automatically reconnect and resume operation in a healthy and well-resourced virtualized environment.
