Tracking the Automatic Recovery for an Element
If an element becomes unloaded, TimesTen Scaleout attempts to reload the element if
the database is supposed to be loaded. During this time, the element status changes to
loading
as the element is being automatically recovered by TimesTen
Scaleout.
You can monitor the element status with the ttGridAdmin dbStatus -element
command. This example shows that the element on the host3.instance1
data instance is in the process of recovering by showing a status of loading
.
% ttGridAdmin dbStatus database1 -element
