Re: Re: Archiver Appliance stuck on initial sampling

Hey Ralph,

Yes, the archiver has a rate limit for searching for the meta info of a thousand by default:

# org.epics.archiverappliance.mgmt.MgmtRuntimeState.archivePVWorkflowBatchSize = 1000

And then the meta channels, I just reckon they are all the same type of PV with 7 meta channels each. The meta channel list depends on your policy file, but I think this is probably all the alarm ones, HIHI, HI, etc.

There is a separate limit for the meta channels search:

# org.epics.archiverappliance.engine.metachannels_to_start_at_a_time = 10000

There are no meta channels if using PVA (which means lots of functionality PVA to CA is different for the meta data). 

Hope that helps
