There are lots of things that breaks pipelines - and so recovery is a necessary thing to think about and build in.
I guess the difference between Pipes and pipes :-) is one of granularity. A (CMS-style) pipeline is probably one you're more willing to restart in its entirety.

Sent by: "IBM Mainframe Discussion List" <IBM-MAIN@LISTSERV.UA.EDU> I misplaced the original post, but somewhere in this thread someone commented that checkpointing is less important. I think I disagree, so just a quick comment from me. Yes, absolutely, there's much more computing power and much better I/O. There are also lots of efficiency gains -- much better compilers, for example. However, if anything the data volumes and related requirements are growing even faster. We've also seen recent, real world incidents involving major organizations failing to meet batch processing deadlines with serious consequences, in some cases to whole national economies. My anecdotal observation is that checkpointing is becoming more important at least on z/OS, not less. By sheer coincidence I'm having a technical conversation this afternoon that (when you boil it down to its essence) is "please implement a certain type of checkpointing." I interpreted this particular remark as a side comment, not really anything that genuinely affects whether pipes are useful in some cases. Yes, pipes are useful. It's not necessary to bash checkpointing in defense of pipes, or vice versa. - - - - - - - - - - Timothy Sipples I.T.
