EPICS aliases

When adding a PV with an alias to the archiver, the archiver uses the NAME/NAME$ fields of the PV to determine the real name. The PV is archived under the real name and an entry is added to the PVAliases table with the alias name. Data retrieval and management are then supported under both names.

For aliased PVs, the PVDetails page will show a line indicating that this PV is an alias for the real PV. In the mgmt webapp’s arch.log, there will be an entry like: Aborting archive request for pv ABC:DEF:ALIAS Reason: Aborting this pv ABC:DEF:ALIAS (which is an alias) and using the real name ABC:DEF:REAL instead.
