>> I run the quickstart.sh of archive appliance, try to archive a PV as "rootHost:ai2"
This is probably a matter of EPICS configuration. You can turn on verbose logging using quickstart.sh -v. This should turn on debug logging and you should get a little more detail on what's happening. You should see messages
like
134883 [Event bus] DEBUG org.epics.archiverappliance.engine.pv.EPICS_V3_PV - pv ofmshankar:arch:sine connectting
......
134884 [Event bus] DEBUG org.epics.archiverappliance.engine.pv.EPICS_V3_PV - pv ofmshankar:arch:sine.RTYP connectting
.....
If your EPICS configuration is set up correctly, you should see messages like
134953 [PVNameDispatcherPVNameEvents 0] DEBUG org.epics.archiverappliance.engine.pv.EPICS_V3_PV -
Connection changed for pv mshankar:arch:sine
......
and so on.
