Issue/Introduction

Question: 

- How can I resolve the following error message which is produced every day?

Nimsoft database [UIMDATABASENAME] table RN_QOS_DATA_XXXX has old samples in latest partition XXX when they should no longer be in this partition 

 

Answer: 

- This situation can be produced if the data_engine configuration has the following setting configured “delete_history_samples = 0”

When "delete_history_samples = 0" , no QoS data will be deleted from the database on maintenance, regardless of what delete_raw_samples had been set to.

By default, on a CA UIM install, this value is set to 720.

Consider increasing the value from 0 to a higher number, restart the data_engine probe, and the problem should be resolved.
