Pretty sure we had a deal with them years ago where we were required to use oracle products for everything. So that's how we ended up with so many of out apps running on oracle DBs.

This is it. I used to work for a consultancy that specialised in Oracle products. Turns out if you want an ERP or HCM, running Oracle EBS with a DB backend on Oracle...running on Oracle Linux...on Oracle Linux KVM hypervisors (where CPU pinning is a recognised and allowed tactic - unlike Oracle on other hypervisors)...it turns out, might be competitively priced.

It's a total lock in. Also, I get the impression that it's almost always up to what the Finance team is used to/familiar with. They decide the finance app - then everything else follows as above due to the financials...which they are in charge of.

I know a guy who migrated workloads off PostgreSQL Enterprise back to Oracle as the performance and availability just wasn't good enough. I don't know enough about DBs to query that much, but he did it.
