What a catalog of misconceptions!
1. CICS IS an application server, provided you don't reserve those words
exclusively to mean EJB server.
2. CICS is not and has never claimed to be a transaction manager - there is no
such product category.
3. Yes, CICS APIs are proprietary. But to refer to them as "APIs to read and
write data sets on a record basis" is incorrect.
4. Transaction management TECHNOLOGY (for your information, Ken) involves a
whole pile of things besides commit and rollback, e.g. logging, locking,
recovery/restart, caching, 2-phase commit coordination.
With all due respect, can I suggest you keep future comments to your area of
expertise.
Apologies to the list for this seriously off-topic posting.
