You have a global ^CODE("TNO","BIO",291,"AKI") that may or may not exist. On the data side of the global ref it can have a boolean value of 0 (false) or 1 (true) and this global is wrapped up in a Caché class accessible from myobject.AKI property. At the object level, how do you check whether the property is defined ie. is there a $DATA equivalent for Cache Object properties? Also, how would you kill /null the property as opposed to making the value 0 (false) or an empty string?

Hi everyone,

I need submit a object have a json string as property of class, but I get an issue, object can't save to SQL table if I take json data to json property. I try making a test class with only json property and get the same issue, no data row in SQL table after run ClassMethod . Some one know what's problem, please help me. Here my test class:

I'm new to Iris, trying to follow this guide ( https://community.intersystems.com/post/k-means-clustering-iris-dataset ) about using clustering. I've followed all instructions until showing the data. At that point, `dataFrame.show()` fails with `java.sql.SQLException: Access Denied`.

I would like to know , if its safe to use %NOLOCK in insert query while doing some parallel processing in Ensemble. We will have pool size of more than 1 for a business process. The business process does an entry in internal meta data table , which will be used for some internal reporting. The same row might get updated by some other process later point of time. i could not produce any error or any issues . Looking forward to hear some opinion on this.

I have an http adapter that calls out to a web service and is looking for a "Completed" response. I want the adapter to wait a certain number of seconds before calling out again to get a response. I have tried setting the retry interval on the business operation but that does not do it. See my code below.

I have previously setup an Atelier project and it was running. I recently received the 1.3 release. Now, I am unable to click on the previously established connection to my Cache server (as seen in the Serve Explorer. I see the connection and the little arrow (implying that there is a hierarchy of items underneath). But, clicking that arrow opens nothing. Ultimately, I was trying to access files on the server so that I could add some new ones to my existing Atelier Project.

I would like to know if it is possible to backup a database via shellscript in Linux?

Thanks.

There are some classes in our code base that contain Methods only (no properties). I told my colleagues that converting them into the ClassMethods should improve performance as it would eliminate unnecessary OREF support at run-time. Some of them replied that it would be microseconds, so what is the reason to bother.

Is it possible to estimate the impact of OREF support of method calls at run-time? E.g., as a % of all CPU load.

I created a Ens.Alert process and set my services Alert on Error as well an my message router. But I would also like to be alerted for warning types. Is there an setting to be alerted for this type?

The following class method "test" contains code that can create a new class, create new properties for classes, or create new methods for classes. "test" runs all three of these processes once, and the code that performs each action is labelled by comments in the method:

ClassMethod test() As %Status
{
    set sc = $$$OK
    
    // Create a class
    set class = ##class(%ClassDefinition).%New("MyClass")
    set class.Description = "This is my test class"_$c(13,10)_"testing %ClassDefinition"
    set class.Super = "%Persistent"

    // Create a property and add it
    set property = ##class(%PropertyDefinition).%New("MyClass.MyProperty")
    set property.Type = "%String"
    set property.Description="This is a property"
    set sc1 = class.Properties.Insert(property)
    do:$$$ISERR(sc1) $system.Status.DisplayError(sc1)
    set sc = $$$ADDSC(sc, sc1)
    
    // Create a method and add it
    set method = ##class(%MethodDefinition).%New("MyClass.MyMethod")
    set method.ReturnType = "%Integer"
    set method.FormalSpec = "x:%Integer,y:%Integer=10"
    set method.Description = "Return product of x and y"
    set method.CodeMode = "code"
    set method.Code = " new result"_$c(13,10)_" set result=x*y"_$c(13,10)_" quit result"
    set sc2 = class.Methods.Insert(method)
    do:$$$ISERR(sc2) $system.Status.DisplayError(sc2)
    set sc = $$$ADDSC(sc, sc2)
    
    // Save the class definition
    set sc3 = class.%Save()
    do:$$$ISERR(sc3) $system.Status.DisplayError(sc3)
    set sc = $$$ADDSC(sc, sc3)
    
    return sc
}

Hi,

I am running terminal on Cache on a Mac High Sierria and going through the ObjectSript tutorials.

However there is no instruction on the Intersystems website as to how to open Studio.

Does anyone know how this is done?

Thanks
