Most economy scale transactional stuff is on things not a lot of people have experience with these days like TPF, or CICS and VSAM and to some extent DB2. Oracle is more of a "mid range" DB for financial workloads and wouldn't be comparatively hard to replace with, say, postgres, as many companies have.
- inshadows 7y agoCould you shed some light on the sector and infrastructure where TPF, CICS and VASM are used? I've never heard of it and had to google it all[1]. What exactly do you mean by "economy scale transactional stuff"? Is something like central bank clearing house?

Some permutation is used at the nucleus of card networks like visa, ACH, most public stock exchanges, and a lot of other financial instrument markets, as well as the systems of record for some of the largest banks and governments.
