Last fall we upgraded our DMS from version 10.2.12 to 10.3.0 CU7. Since then, we've been getting a notice after a restart of each DMA that "DataMiner IDP is licensed, but no Elasticsearch database is active on the system. Therefore, scheduled workflows are not available". At the time I did ask one of the Skyline developers that we normally work with, and they thought that it could be ignored. We do have 2 Aspera Orchestrator elements that appear to use workflows as shown below. Is this a nuisance message or do we really have an issue?
There is no issue with your system, you will just be limited in the available features that IDP can offer.
