adding business hosts programmatically to a pre-existing production.

Add a new Business Host. If you want to add several, call CallProductionUpdateAndSaveToClass method once at the end.

Include Ensemble

Class test.prod
{

Parameter DOMAIN = "Ensemble";

/// Add new Business Host.
/// productionName - name of production class
/// name - name of item you want to add
/// class - class name of the item you want to add
/// w $System.Status.GetErrorText(##class(test.prod).add())
ClassMethod add(productionName As %Dictionary.CacheClassname = "isc.py.test.Production", name As %String = "MyOperation", class As %Dictionary.CacheClassname = "isc.py.ens.Operation")
{
    Set production = ##class(Ens.Config.Production).%OpenId(productionName)
    
    Set item = ##class(Ens.Config.Item).%New()
    Set item.PoolSize = 1
    Set item.Name = name
    Set item.ClassName = class
    Set:item.Name="" item.Name = item.ClassName
    Set item.Enabled = $$$YES
    Set sc = production.Items.Insert(item)
    Quit:$$$ISERR(sc) sc
    Set sc = $$$AuditModifyProductionConfig(production.Name,item.Name,$$$Text("Item added to production using generator in " _ $classname()))
    Quit:$$$ISERR(sc) sc   
    Set sc = ##class(EnsPortal.Template.prodConfigSCPage).CallProductionUpdateAndSaveToClass(production,"","SaveProduction")
    Quit sc
}

}

Hi Fernando,

Check out this other developer community article: How to Export and Import Ensemble Components and Productions

It includes a link to the documentation on deploying a production.

If you need to do this programmatically you'll want to review the Ens.Deployment.Utils class reference.

I agree this approach looks good.
