Method Detail

getDatabaseUpgradeState

public UpgradeState getDatabaseUpgradeState()

Description copied from interface: DatabaseUpgradeStateManager

This does not return the most up to date state of the cluster. If you rely on specific states that are in DefaultClusterUpgradeStateManager.AUTO_TRANSITION_STATES then you should use ClusterStateManager.getUpgradeState() instead.

Specified by:

getDatabaseUpgradeState in interface DatabaseUpgradeStateManager

Returns:

the upgrade state of the cluster as represented in the database

areDelayedUpgradesHandledByCluster

public boolean areDelayedUpgradesHandledByCluster()

Description copied from interface: DatabaseUpgradeStateManager

Checks if delayed upgrades are handled by the cluster.

Delayed upgrade tasks are handled by the cluster when ClusterUpgradeStateManager.CLUSTER_UPGRADE_STATE_DARK_FEATURE is turned on and cluster is not in UpgradeState.STABLE. In non-clustered environment this will always return false

Specified by:

areDelayedUpgradesHandledByCluster in interface DatabaseUpgradeStateManager

Returns:

true if and only if delayed upgrades are handled by the cluster

areUpgradesAllowedByCluster

public boolean areUpgradesAllowedByCluster()

Description copied from interface: DatabaseUpgradeStateManager

Checks if upgrades are allowed to run in the cluster.

The difference to DatabaseUpgradeStateManager.areDelayedUpgradesHandledByCluster() is that it will allow running upgrade tasks when the cluster state currently allows running upgrade tasks during normal Zero Downtime Upgrades operation.

Specified by:

areUpgradesAllowedByCluster in interface DatabaseUpgradeStateManager

Returns:
