We are a CICS shop with IMS DB (DBCTL), but I've been curious for a while about
the differences between how CICS works and how IMS TM works. I couldn't find
anything on the web. Anyone have a link to a good reference?
Thanks,

Frank,
Disclaimers.
1. I've never been involved with IMS/DC in application design or
programming but have worked with DC as a sysprog.
2. It;s over 10 years since I was involved.
The 3 IMS/DC sites I worked at did 7*24 dispatching, among other things,
with a lot of docket printing which seemed to work well within IMS/DC.
The other points, probably to be poorly explained, is that DC has
different types of regions eg. message regions and other regions for
different types of processing. This allowed for micro management of DC
without the overhead that equivalent micro management of CICS would
cause. This I think also assisted in recovery when things went turtle up.
