Yeah, lots of corporate backend code is Java, and Java is a great choice for backend/server code. I've never seen Oracle anywhere, though, not in banks and not in governments. I've mostly seen Postgres and MSSQL and some MongoDB.
I've been working in Wall St. banks for the past 30 years, and I've never used an Oracle database. The investment banks were all Sybase shops in the 90's, and a bunch of them still are. In my experience those that do move are most likely to go to SQL Server, since its Sybase roots make the transition a little easier.
When something has been there for 20+ years switching costs are big.
