Hotfix: data_engine-9.20HF5 Release Date: 1st April 2020 Applicable for: UIM 9.2.0 This is a hotfix on top of data engine that comes with UIM 9.2.0 HF4. Below issue got fixed under this hotfix. 1. DE451184-: 31794332- data_engine stops processing all qos_processor enriched metrics after restart 2. DE451327-: 31722751- After updating origin via qos_processor, data_engine cannot store their metrics Description -: Once qos_processor updates the origin for a metric everything works until the data_engine is restarted. If the data_engine is restarted after qos_processor has updated the origins, the data_engine, no longer databases these metrics. The solution to this problem is to use nim_origin(if present), instead of origin field of S_QOS_DATA table while maintining cache for existing record in data_engine.
