About Management States

The Operator uses the TimesTen ttGridAdmin mgmtExamine utility to determine the health of the management instance. The Operator also synthesizes a management state that describes the status of the management instance in a single value.

For information about the TimesTen ttGridAdmin mgmtExamine utility, see Examine Management Instances (mgmtExamine) in the Oracle TimesTen In-Memory Database Reference.

For example, you can use the kubectl get tts command to observe the state of a TimesTenScaleout object.

kubectl get tts samplescaleout
NAME             OVERALL   MGMT     CREATE    LOAD              OPEN   AGE
samplescaleout   Normal    Normal   created   loaded-complete   open   10m

Note that the management state is Normal. There are additional examples in the chapter where you have the opportunity to observe the management state.

Here are the management states:

• ActiveAgentUp

• ActiveDaemonUp

• ActiveDown

• Error

• Normal

• Unknown

Error
