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.

InterSystems is pleased to announce that InterSystems Caché and Ensemble 2018 are now released!

New in these releases are features that improve security and operations, including:

· Key Management Interoperability Protocol (KMIP) support
· Microsoft Volume Shadow Copy (VSS) integration
· Integrated Windows Authentication support for HTTP
· SSH enhancements

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

Hi Community!

I'm pleased to announce that InterSystems IRIS is available on Microsoft Azure Marketplace!

This is the second public cloud offering of InterSystems IRIS after recently announced Google Cloud Platform support.

Does anyone know how to loop through a segment that is part of an ordered set in a Business Rule and if one of about 10 possible values exist in any of the iterations of the segemnt:field I then allow the message to be skipped?

It seems like it should be fairly simple, but i am having a difficult time figuring this out. The Contains function only allow for one value to be identified. I have tried the intersectsList and while I think I have it formatted correctly i believe it only allows for 4 values to be verified.

Hi Everybody!

We are pleased to invite you to the upcoming webinar "Continuous Delivery Using Containers" on 21st of August at 10:00 (Moscow time)!

Where can I find CSP file in TRAKCARE. Seems i can find js file only but not CSP file in TRAKCARE T2017, may i know the path where store the CSP files? Many thanks.

Good afternoon everyone,

I hope you are well,

I am currently working on the below opportunity and if anyone here would like to hear more details please feel free to contact me on 01908 886 030 or teo.rusu@identifiglobal.com

or "Bonus Breakage"

In our last lesson, we added a relationship between 2 persistent classes. We are clearly going to need to start creating REST Services to expose CRUD operations for each of these classes, but before we do that, we should really finish defining our linkages. We added code to our Widget toJSON to spool off related Accessory data, so we should really do the reciprocal and allow Accessories to return all Widgets that are compatible.

I have already mentioned my project CacheBlocksExplorer recently in two articles
