Hi Jamie and Michael,

Thanks for your message, however what I want is how can I generate some

PVs in some productive JAVA/Python program/scripts for communicating,

not the python CA interface nor separately run an IOC; just like

openXAL, to my understanding, one of the apps of this JAVA based

framework --- 'virtuallinac' once be launched, an IOC would be running

background, not by conventional way based on EPICS base routines.

I think Michael's pythonIoc is something what I'm looking for, thanks.

Two very good python interfaces:

pyepics:

pcaspy:

(https://github.com/Araneidae/epicsdbbuilder) allows you to create EPICS

database files in Python. However, the result is a .db file which still

needs to be executed by an IOC as a separate step.

is a Python interpreter linked with an EPICS IOC and integrated with

epicsdbbuilder and some Python device support. This allows you to write

fairly concise scripts which generate PVs in a simple way.
