Urgent Help - Unable to find/update Ensemble settings using Ens_Config.Item class programmatically for all Business Hosts

Hello T,

Some settings such as AlertOnError aren't in Ens.Config.Item but are stored in the production definition class.

edit: see my comment below, these settings are in the production definition, but you seem to be able to modify them using Ens.Config.Item as well.

Perhaps you could use the System Default Setting?

For something like this, especially with urgency, I'd recommend reaching out to your InterSystems rep or the WRC.

Hi

There are a couple of things to note here:

1) You can programmatically update the Production Item settings as well as the settings of the Adapter bound to the Service or Operation. What you won't see are those modified values on the Production Item Settings TAB though if you do a $$$TRACE in your code you will see that the setting value is the value to assigned to the setting.

2) The Production Item has groups of common attributes such as Information, Connection, Alerting, Development. Most of these are common to almost all production items. 

3) If you want to add a custom setting to the Production Item define it as a property. for example:

Property MaxNumberOfLoops As %Integer [ InitialExpression = 200 ]; 

and then if there isn't already a PARAMETER Settings include the following:

Parameter SETTINGS = "MaxNumberOfLoops:Basic";

This will add a field to the Basic section of the Settings TAB and in the OnProcess(), OnProcessInput() or equivalent methods you can access the property value using  normal object instance syntax:

set maxloops=..MaxNumberOfLoops

4) For a more complex example where you might want to include a drop down list of values derived from a class/table in the database you can do the following:

Property Organization As %String;

Property OrganizationId As %String [ Calculated ];

Parameter SETTINGS = "Organization:Basic:selector?context={Nigel.Production.ContextSearch/Organizations}"';

The code for this ContextSearch is specified in a class method called "Organizations" (the name that follows the ContextSearch/Name} in a class that has the following attributes:

This will populate the list with the Organization Name and you will want to maintain an array of "Organization Name" back to Organization Internal Id. You can specify the Caption to introduce spaces and other cosmetic features.

There are also some built in functions that you can make use of for the selector such as a Calendar for Dates/Date&Time, A Directory Selector, File selector, basically the standard Zen custom components which canbe handy.

As a matter of interest what production item doesn't have the Alerting section. If it doesn't, and given that apart from the development and testing section if there isn't an Alerting Section then there is probably a very good reason why alerting is just not appropriate for that item. Even Ens.Alert has an Alerting section. LOL

If you wanted to add some additional field to the Alerting section then define the property but link it to:

PARAMETER Settings="myProperty:Alerting;"

on the other hand:

I once designed an architecture where I had a an abstract device class and a whole lot of abstract adapter classes which I inherited into persistent classes and each persisted device had a unique name and in the OnInit method I would get the production item name and if i could find an entry for that name in my device Index global I would use the values from my device table to populate the production item with specific device or adapter setting values. It is a bit complex to explain here so let me know if you want any more information on how I made it work but I think that Ensemble ultimately added that sort of functionality in later releases. I think i developed my own version for Ensemble 2014 or earlier.

Finally if you are not sure if a Production Item Setting exists use the following code:

Set outputContentType=$GET(pInput.Attributes("Content-Type"),"text/xml")

and if apart from the

PARAMETER Adapter ="......";

property Adapter as EnsLib.......;

you can use something like:

set xyz=$property(..Adapter,{Property_Name}) if the property doesn't exist then it will return a <property does not exist> error if it is not a property of the Adapter class and you can check that by using the code:

if ##class(%Dictionary.CompiledProperty).%ExistsId("Classname||PropertyName") is true then the property is a property of the Adapter class

You could also try

quit ##class(Ens.Director).GetCurrProductionSettings(.pSettings)

and then

according to the documentation you should be able to use:

in Ens.Production

classmethod ApplySettings(pProductionName As %String, ByRef pSettings) as %Status

Apply multiple settings to a production pProductionName is the name of the Production to which to apply the settings
pSettings is a local array of settings structured in the following way:
pSettings(<itemName>,<target>,<settingName>)=<settingValue>
Where:
<itemName> is the configuration item name in the production
<target> Is one of:
Item: Means the setting is a property of the item itself, such as PoolSize
Host: Sets a host setting
Adapter: Sets an adapter setting
<settingName> is the setting name
<settingValue> is the desired value of the setting.

and also in Ens.Production to get the production settings use: \

classmethod GetSettingsArray(Output pSettings) as %Status
 

I haven't tried them but thats what the documentation in the class says

Your problem is the FindSettingsByName method, above, does not find settings you see in the production settings tab for some items, right?

They are shown in black (not green from the class definition or blue from System Default Settings)?

If you do: SELECT ID, Production, Name, Settings FROM Ens_Config.Item do you see them in the Settings column? 

Do you see the settings in the production class XData block?

Do you have examples where a given setting shows with one items but not others?
