The reason why both(DB2/Adabas) are still with us is probably because
they ultimately offer a different set of benefits to their users.
Bad assumption IMHO. Mainframe is a dino, a lot of things still exist on
mainframe because of conservative users. At a risk of starting new war I
can provide some examples:
a) VSE. It is obsolete, insecure, in fact "moribound". Oftenly it is run
on very small machines, so this workload could be easily run on cheaper
platform. The problem is nobody migrated the application.
b) IMS. Yeah, I know that many big companies still use it and are very
happy of it. Question is how many *new* applications are IMS-based, why
other platforms do not have IMS-like database. They have DB2 and other
relational databases, but not IMS.
c) ISAM. It is dead now. Death sentence was known for 30+ years. Even
few years ago there still were shops using ISAM files.
d) TPF. Similar status to VSE.
