V4 Name Server

Task

Investigate a network client API for data and name resolution.

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)?

Channel Access Client User Interface

Is the low-level V4 CA client API all that's needed? Or is a wrapper needed that e.g. holds the data in a container?

• Waiting for 'caget' example code. How easy can a simply 'ca get' be?
• Assert that display tools, archiver, EPICS 'office' can do what they need to do with the CAC API.
