Replace hard delete with soft delete.

You soft delete by creating a new property, usually a DeletedOn timestamp. If it's empty then the record is not deleted.

Deletion now consists of setting DeletedOn property to a soft deletion timestamp.

As an additional precaution you can add a BEFORE DELETE trigger which always errors out, forbidding hard deletions. It would save you from every delete except for global kill.

Additionally, you can add versioning, check out this discussion.

Create a unified DELETE trigger (foreach row/object). It would catch both SQL and Object access.

That said I usually advise against hard delete. In virtually all cases soft delete is better.

There seems to be different ways to approach declared IRIS state by codifying things, you can codify the exported objects and import them or like you mentioned, use the installer method that builds things as code....  

Indeed, there is a declarative approach and imperative code approach. And there are several declarative ways to populate the data. %Installer is excellent for the initial population, but the user must remember to check for the existence of items he's trying to create. That adds challenges for CI/CD in non-containerized environments.

Ended up with this implementation:


Parameter NOSECTION = "DEFAULT";

/// do ##class().INIToLocal(,.ini)
ClassMethod INIToLocal(file, Output ini) As %Status
{
	#dim sc As %Status = $$$OK
	kill ini
	set stream = ##class(%Stream.FileCharacter).%New()
	do stream.LinkToFile(file)
	set section = ..#NOSECTION
	while 'stream.AtEnd {
		set line = stream.ReadLine()
		set line=$zstrip(line, "<>w")
		continue:($e(line)="#")||($l(line)<3)
		if $e(line)="[" {
			set section = $e(line, 2, *-1)
		} else {
			set key = $zstrip($p(line, "="), "<>w")
			set value = $zstrip($p(line, "=", 2, *), "<>w")
			set ini(section, key) = value
		}
	}
	
	kill stream
	quit sc
}

/// do ##class().LocalToINI(.ini)
ClassMethod LocalToINI(ByRef ini, file) As %Status
{
	merge iniTemp = ini
	#dim sc As %Status = $$$OK
	set stream = ##class(%Stream.FileCharacter).%New()
	do stream.LinkToFile(file)
	
	set section = ..#NOSECTION
	set key=$o(iniTemp(section, ""),1,value)
	while (key'="") {
		do stream.WriteLine(key _ "=" _ value)
		set key = $o(iniTemp(section, key),1,value)
	}	
	do stream.WriteLine()
	kill iniTemp(section)
	
	
	set section=$o(iniTemp(""))	
	while (section'="") {
		do stream.WriteLine("[" _ section _ "]")
		
		set key=$o(iniTemp(section, ""),1,value)
		while (key'="") {
			do stream.WriteLine(key _ "=" _ value)
			set key = $o(iniTemp(section, key),1,value)
		}
		
	 	set section = $o(iniTemp(section))
	 	do stream.WriteLine()
	}
	
	set sc = stream.%Save()	
	kill stream, iniTemp
	quit sc
}

While local access is not possible from Native API, you can work with production items directly:

prod = iris_native.classMethodObject("Ens.Config.Production", "%OpenId", "ProductionClassName")
items = prod.getObject("Items")
count = items.invokeInteger("Count")
for i in range(1,count+1):
    item = items.invokeObject("GetAt", i)
    // do something with item here

Alternatively, you can either use SQL access (check Ens_Config.Item table) or write a proxy method in objectscript to marshall locals (to dicts probably).

If it's a non-production instance you can try running iris windows service (IRIS controller for IRISHEALTH in your case) under your windows user account, instead of the default system one. That usually helps.

If it's not possible, either give system account rights to irissession  or create a new user with rights for irissession and run the iris service under that account.
