This method enumerates 'Applications'. Individual instances of Cache or Ensemble may advertise 'Applications'
which typically represent a 'service' that is provided, for example, the System Management Portal.
The AppId parameter is reserved for future use.
The information regarding the Applications is returned as a list of dictionary objects each which contains a set
of keys and values describing each application. Each application has these well known keys:-
classmethod EnumerateInfoProvidersClose(ByRef qHandle As %Binary) as %Status
classmethod EnumerateInfoProvidersExecute(ByRef qHandle As %Binary) as %Status
This Query enumerates 'InfoProviders'. An InfoProvider is an object (implemented in an external library) which
knows how to find instances of Cache and determine information about the 'applications' those Cache instances
support. An example of an application would be the system management portal.
Currently there are two InfoProviders available, the 'Bonjour' provider which uses Apples Bonjour
protocol to find instances of Cache on the local network and the 'Http' provider which uses Http to discover
the applications which individual Cache instances provide.
The result set contains two rows, Name and Description. Use this name with the 'EnumerateInstallations' or 'EnumerateApplications'
query EnumerateInstallations(pProviderName As %String)
This query enumerates 'Installations', that is, individual instances of Cache or Ensemble. Depending upon which InfoProvider
is selected, these installations may be local to this machine or remote. The 'HttpProvider' will enumerate local installations whilst
the 'BonjourProvider' will enumerate installations that have been advertised by the 'Bonjour' protocol. The query requires the name
of the InfoProvider to use such as 'HttpProvider' or 'BonjourProvider. The AppId parameter is reserved for future use.
The information regarding the installations is returned as a list of dictionary objects each which contains a set
of keys and values describing each installation. Each installation has these well known keys:-
host: The hostname of the computer where the installation is located
name: The name of the instance of Cache or Ensemble
serverPort: The superserver port
status: The current status of the installatio, 'up', 'dn' etc
version: The $ZV version string
