Hello Shashank, it looks like it's had a problem for over 2 years, is the Data Warehouse database local or remote? is there a firewall port open? Can you connect to the database from the engine machine? The credentials should be in /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf as your using 4.3 the version of postgresql is 10 and using scl scl enable rh-postgresql10 "psql -h localhost -U ovirt_engine_history -d ovirt_engine_history" if it's using the standard user, database and is local. Regards, Paul S. . ________________________________ From: Ayansh Rocks <shashank123rastogi(a)gmail.com&gt; Sent: 24 June 2020 12:47 To: Staniforth, Paul <P.Staniforth(a)leedsbeckett.ac.uk>; users <users(a)ovirt.org&gt; Subject: Re: [ovirt-users] Re: ETL service aggregation error Caution External Mail: Do not click any links or open any attachments unless you trust the sender and know that the content is safe.
