Hi,

Along the lines of configuration and management, I was wondering what

the plans were for EPICS V4. Would it be possible to have a different

mechanism than a text-based startup file? I'm thinking out loud here,

but this is what I'm suggesting:

Have IOCCore boot as a generic kernel with a configuration and

management API (probably something other than CA). I don't know what

all can be loaded after the boot of the kernel, but it would be nice to

be able to at least send the DBD and DB configuration explicitly via a

deployment API. Perhaps even device/driver binaries can be loaded this way?

I've seen this technique become quite popular in the business middleware

arena. The JBOSS project (application server) now runs as a generic

kernel which grabs its configuration after boot. There is an extensive

config and management API which provides all sorts of meta-data, and

also allows for run-time re-configuration.
