/tc:tc-config/servers/restartable
The fast-restart persistence mechanism must be explicitly enabled for the TSA using this element:
<restartable enabled="true"/>
In case of TSA failure, fast-restart persistence allows the TSA to reload all shared cluster data.
To function, this feature requires <offheap> to be enabled on each server. To make backups of TSA data, the backup feature requires this feature to be enabled.
