Hi, I need a check from the experts my understanding of channel access is correct. http://www.aps.anl.gov/epics/base/R3-14/10-docs/CAref.html#Configurin1 We have a couple of systems in development for which I'd like to use the EPICS_CA_MAX_ARRAY_BYTES feature, quite extensively at up to 4.2MB. Nothing from the legacy infrastructure (either clients or servers) will need access the new big arrays, but there will be interchanges for 'regular' (<4k) records between the new servers and its legacy surroundings. Only dedicated clients will be accessing the big arrays, they'll also access regular records, both from the legacy and new systems. As I read it, anything 'regular' goes on the 4k freelist, compatible for all the systems. Anything else has a dedicated EPICS_CA_MAX_ARRAY_BYTES freelist. So there's no cross talk and it all plays nicely. check? Thanks, Matthieu
