When they didn't get the decision they wanted, they quickly escalated to exec and director level, and the exec of a major shareholder to try and get the decision overturned.
It wasn't an especially pleasant experience personally, because obviously it involved a lot of very personal attacks by a vendor, but at the same time it was fascinating to watch how they networked from the top down to try to get the decision that they wanted, and run roughshod over the SMEs and process.
Some years later one of the sales team sent me a "Virtualisation for Dummies" book and told me I could learn something from it.
It's made me always work to get Oracle and CA products replaced wherever I have a voice as a result. They may have scored one small $500k deal at that previous employer. I've often found I'm not alone in my dislike for these companies for their shady sales practices, and at least for Oracle enough of us worked together to lose them an 8-figure deal by showing we could do something different for far less once.
Open source created modern Oracle. I worked for a company built around Informix, and that database engine was one of the largest expenses of the company. I think we paid like $40k/socket in 2000. Today, you use an open source database to build your product.
So Oracle had to start selling integrated solutions. They do evil shit like pay higher commissions for salespeople to cross-sell their colleagues. So the Oracle Financials guy gets paid more to sell Identity crap than the identity guy. So the sales idiots form all sorts of weird alliances and kill each other.
Thing is, the vendor simply happened to build upon Oracle. If the software supported DB2, or more likely, supported a migration path from Oracle to DB2, I suspect we would have gone with that.
On another hand...
A lot of "Oracle required" software uses a ton of Oracle-specific stored procedures and other components, in fact, I have encountered an MRP software package that was written entirely inside Oracle database. All PL/SQL, with some bits of embedded Java.
