Analytical Ecosystem

Due to cascade interrupts, a system may have several interrupted objects from a single root cause event. With automatic recovery enabled, the recommended default, Unity tries to recover all objects at set time intervals.

When a system or a large number of objects are interrupted, it may become a strain on Unity and managed system resources. Indicators of strain include the following:
  • You fix the root cause but recovery is not progressing.
  • Alert details show the root cause as being out of sessions or load slots.

To allow adequate time to analyze and correct any issues on the Teradata systems, temporarily disable automatic recovery. When the issues are resolved, restore automatic recovery.
