I think grant types are not used by he resource server, only by Confidential and Public clients.


briefly, perhaps not 100% correctly - use Google for more details, claims are characteristics provided by OIDC (OpenID Connect) server that describe authenticated user. e.g. Caché by default supports these claims (and more):

preferred_username, email, email_verified, name, phone_number, phone_number_verified, iss, sub, aud, exp, auth_time, ...

claims can be used by the access_token to provide additional information about the user passed to the resource server when calling REST method. Some claims are mandatory, some are optional. You can provide optional claims by the SetClaimValue() method.


Hi Praveen,

this is not going to be an exhausting answer but rather a summary of choices you have.

First thing to answer: are you working with a legacy application, that stored data in globals, not using our Cache persistent classes? In this case, you would like to follow Sean's globals to classes mapping guide.

Another option, suitable in cases where you have a mix of persistent classes and only some data stored directly in globals, you may consider using custom SQL queries. In such query you implement code that iterates over your global nodes and expose result as SQL resultset. You can then call query as a standard stored procedure. see Cache online reference for mode details here.

There is one more option too, which could be used in some special cases when global is a simple structure. In such case you could create a new persistent class definition and simply override the storage generated during its compilation to reflect your global structure. This is less flexible than using SQL mapping mentioned as first choice, but could be easier for you.


there is an easy solution to your issue. Simply use a Cache Task Manager. Create a new task, and within code, instantiate Ensemble service Ens.Director,


Set tSC=##class(Ens.Director).CreateBusinessService("your service configration name",.tService)

If ($$$ISERR(tSC)) Quit
Set tSC=tService.ProcessInput(%request,.output)
If ($$$ISERR(tSC)) Quit
If $IsObject($G(output)) {

   // do whatever you want here


Noone would give you exact numbers. It really depends on your use case.

However, adding 200 properties to an Ensemble message (not considering other classes as you pass just messages) may either simp0ly mean that you add 200 properties to ONE class or to MANY classes, depending how clever the original design of your production was.

You may, or with the same probability many not, need to change the message design and switch to virtual documents ... it really depends on many factors unique to your particular use case - throughput expected, load of data incoming etc etc... 

Jose, $lb() holds STORED values of you object instance. If your opened instance modified property(ies) then I see no point of looking into stored data, just serialize you IN-MEMORY values to JSON.

On the other hand, if a process A opened and modified instance of the object and without saving and you want to serialize the same instance from process B, then again, there is no difference between opening an object instance or using some custom serialization directly from stored data.

It is not good practice anyway to keep objects opened for a long time without saving their new values.

lastly, my comment about JSON array was that JSON array doesn't need to know the name in the name:value pair so you can easily write a custom JSON serializer to serialize directly $lb() into JSON array.



maybe I missed your original business case need, can you explain why current implementation is not good enough for you?


how would you determine names of properties / keys for a JSON name:value pairs without opening an object instance or retrieving those names from somewhere else?

or are you happy to express it as JSON ARRAY ?

I work with Cache for decades and never knew about ExtentFunc(). There is always something to learn...

Mike, in Studio use Show Other View to display the generated INT code for the Sample. Employee class. You'll find the ExtentFunc() there. You may need to compile the Sample.Employee class first to re-generate the INT code.


you do not invoke web methods directly. You need to create a client class by consuming a WSDL file that your service exposes. There is a wizard that guides you through the process of client creation. Apart to client class itself the wizard also generates all data types used by a web service. Please consult documentation here.

There are some other option when using Ensemble but I suggest you follow the link above.


Hope I understood your question correctly, if not then let me know.

In general, when dealing with XML VDoc documents (files), you need to create a production that uses services based on

EnsLib.EDI.XML.Service.FileService, operations based on EnsLib.EDI.XML.Operation.FileOperation and a routing process - EnsLib.MsgRouter.VDocRoutingEngine. There is no need to do any coding, just supply parameters in the production diagram.

You may need to provide DocSchemaCategory setting for a service, for this, you need to import the XML Schema, using Import button at Ensemble->Interopeate->XML->XML Schema Structures page.

for actual routing, you need to design a rule, and supply path to the document element/attribute that's used to decide where the rule sends document to. I prefer using XPATH expressions for this.

An example of routing rule contents is here:

<ruleDefinition alias="" context="EnsLib.MsgRouter.VDocRoutingEngine" production="tzp.dasta.router.Production">
<ruleSet name="" effectiveBegin="" effectiveEnd="">
<trace value="Document.{/dasta/is/ip/lo/loi/@material}"></trace>
<rule name="">
<constraint name="source" value="Dasta3Zadanka"></constraint>
<constraint name="msgClass" value="EnsLib.EDI.XML.Document"></constraint>
<constraint name="docCategory" value="ds030101"></constraint>
<when condition="Document.{/dasta/is/ip/lo/loi/@material}=&quot;B&quot;">
<send transform="" target="Dasta3Biochemie"></send>
<send transform="" target="Dasta3Mikrobiologie"></send>

You can create a VDOC document from a persistent (any, not only persistent) object, as long as it extends also from %XML.Adaptor. First, you serialize your object instance to XML stream or string, and then using ImportFromString/ImportFromLibraryStream (or other - see online reference for EnsLib.EDI.XML.Document class) method you instantiate a VDoc document.
