Allegedly 90% of the world's biggest banks run their core systems on mainframes. Oracle did offer their database on mainframe but stopped and the last supported release went EOL in 2013. There's still possibly extended support being paid for, but sounds like they possibly don't have a lot of the bank-on-mainframe market.
I wonder what those banks use for their databases. IMS or DB2 maybe?
Not so say your comment is wrong, there are thousands of banks and average assets of few hundred million. Unlikely they would fork out millions for mainframe setups. Majority of those could be on Oracle as you say.
- bayindirh 4y agoI know that one of our biggest national banks still run on mainframes for their core banking infrastructure, but there's so many satellite systems which are way more modern and use separate systems and servers. In these cases generally DBs are migrated to external clusters of their own (like HPE Superdome, Exadata or similarly tailored hardware) and connect via IB or IB like low latency, high performance networking. AFAIK, the bank I'm talking of is working with "Don't fix what is not broken" motto, and only move what's necessary to modern or external systems.
- throwawaylinux 4y agoHuh. You mean the bank running the mainframe has moved database to a cluster of other systems? What does the mainframe run then? Business logic / applications in COBOL or ABAP or whatever?
