Name Server

What would a name server look like that supports

1) Life channels (ChannelAccess), including channels provided by backup systems in a redundant setup.

2) Archived channels

3) Possibly other EPICS data sources like Alarm channels?

Hoping to use something existing. Get OpenLDAP [1] and check the following:

  • Can it be used to store record names, server addresses, maybe more ('primary' server, fields, ...)? Try a simple setup, use the command-line ldapsearch to retrieve data.
  • Does it allow for redundant servers, automatically syncing?
  • How to best interface it (API)?
