So another topic that has been of interest to a number of people since the beta was put up last week is in regard to Studio Hooks and Atelier. This requires a bit of background and then some discussion of how the architecture of Atelier necessitates some changes and then what our current thinking on the subject is.

Studio hooks were added to Cache over 10 years ago. They have two primary usages. The first is that on an appropriate action such as creating a new document, or compiling a document a callback is executed whose job is to interact with external source control systems.

I have been meaning to make a post about this topic for a few weeks and the other day an issue came in through the WRC about it so it seems this is a conversation we should be having. I want to begin by taking a few moments to explain "Why Atelier" then we can talk about what this means in the general sense for Studio and Atelier and Caché developers. We have wrestled with what to do with Studio for years. When I moved to Product Management in 2008 this was already a "thing". At the time we could not reach a consensus. Some felt Studio was fine as is.

Hello! 

I'm trying to make a simple hello world program for iKnow but the documentation only shows examples using the scripting language or XML XData. 

The domain is already created and configured, what I hope for is to be able to work with the data in some high-level language. 

Is it possible to do something like this:

int domainId = 1;
IKnow iknow = new IKnow( domainId );
List concepts = iknow.getTopConcepts();

Any feedback will be greatly appreciated!

Is the default language (i.e., $$$DefaultLanguage, which is used as the basis for localization with $$$Text/etc. at compile time) always "en" for new Caché installations, or could it be different? How is this determined? I don't see an option to select a language during Caché installation.

Also, is there a supported/preferred API for setting the default language? Looking at %occMessages.inc, one option would be:

Set $$$DefaultLanguageNode = "en"

But I'd expect there to be a classmethod for this somewhere (and haven't managed to find it yet).

Attached is an example of a web service client that can be used to do a lookup against the CMS NPPES database to validate and retrieve information about a given National Provider Identification (NPI).

Hi Community!

I'm pleased to announce that  the winner of the Global Summit Free Registration Contest is...

I'm working on a proposal for a deployment tool development project and I was wondering if anyone had any experience with such a thing.  

We use Healthshare and implementations for new clients are tedius and lengthy.  Lots of ensemble service, registry value, lookup tables, namespaces and other things have to be created and configured. 

I would like to create a Zen or CSP page based deployment tool that can do all this with a few parameters and some custom code.

Has anyone done this?  What are some pitfalls you ran into?  Any unique ideas you included?  Other general thoughts?

InterSystems is pleased to announce that Caché and Ensemble 2015.1.4 are now available as maintenance releases.
For a complete list of the corrections in 2015.1.4, please review the release notes.

Caché and Ensemble 2015.1.4 are available today for the same platforms as 2015.1.3.
The complete set of supported platforms, including specific point releases and/or patches, is detailed in the Supported Platforms document.

A customer needs to assemble a HL7v2 ADR A19 (ADT Response - Patient Query) message programmatically, inside Ensemble.

Does anyone have an example of how can one create a HL7v2 message programmatically? 

Question

I am configuring IIS to work with the CSP Gateway but I'm running into this error:

"The Module DLL 'C:\Inetpub\CSPGateway\CSPms.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture."

Hi Community!

Meet the new group in Developer Community:

InterSystems Data Platform Blog!

In this group you'll find technical posts form InterSystems engineers and Community about InterSystems Data Platform technology cases which we consider as good or even best practices.

Every article in this blog passes InterSystems engineers' reviewing procedure and only then becomes available. You are very welcome to comment and share it!

We'll find best practices of InterSystems Technology implementations, will transform it into articles and will deliver for you in this group on a regular basis.

Hi all,

I was wondering, what is your favourite public cloud provider?

What is your level of engagement with the cloud provider? Are you testing their infrastructure? In which case I'd expect you being progressing a parallel test with at least a second provider ;-) Or, are you already running a production environment?

--

OK, so, let me be the first one to share my experience with one specific cloud provider.

Hi-

I'm curious to know what InterSystems clients are using for csp based web development methodology.

Are you doing tag based development, or class based development?

If you are using tag based development, what tools are you using to create the look and feel of your web pages?  Are you using tools like Adobe Dreamweaver, or do your developers sit down and code HTML using plain editors like Notepad and Notepad++

Are you doing prototyping of web pages and then adding CSP tags, or are you just developing the finished csp page with no prototype?

Thanks
Ken

Atelier needs Java 1.8 to run, but manage diferent versions of Java can be tricky in OSX

Hi, Community!

We've started InterSystems Global Summit Free Registration Contest this week.

Here is interactive leaderboard available! 

In MSSQL I think you can do something like this:

select *
from HS_IHE_ATNA_Repository.COLUMNS
where TABLE_NAME='Aggregation'

How can I do this in Cache SQL?

[%msg: < Table 'HS_IHE_ATNA_REPOSITORY.COLUMNS' not found>]

I'm planning to have a web-based management and deployment interface.  For now I have started writing some .mac scripts.  Will I be able to call these from a web page?  Or do I just need to start with Zen?

A customer needs to add lines in the Excel sheet before the MDX resultset content.

Is there a more elegant/convenient way than modifying %DeepSee.UI.MDXExcel methods ?

Thanks in advance.

Sylvain

C:\data\backup.bat :

C:\InterSystems\Ensemble\bin\cache -s"C:\InterSystems\Ensemble\Mgr" -U%%SYS ##Class(Backup.General).ExternalFreeze() <C:\data\login.scr 

echo %ERRORLEVEL%

rem note that we need to check errorlevel from highest to lowest here.

We released another set of improvements this week and will continue pushing out fixes and features in the upcoming weeks.

Thank you for using the InterSystems Developer Community and please continue providing feedback.

Hi, Community!

Hi,

Does anybody know when Ensemble 2016.1 will be general availability?

We are holding off upgrading, providing the wait won't be too long.

Thanks,

Graham

Developing an idea with RuleEngine in XData, we could even refuse from editing full class and edit only valuable xml. Sometime ago I have already written an article(in russian) about such possibility, even more, in that article I wrote about compilable JavaScript to Caché. 

Opening File

This possible with %Studio.AbstractDocument. While extending this class, developer should add a Projection.

  Projection RegisterExtension %Projection.StudioDocument

Some days ago Alberto has written a very interesting article about the usefulness of ObjectGenerators available in Caché.

In this article, Alberto shows an example RuleEngine based on XData, and how it is possible to improve the process of filling such rules. Caché Studio has a Studio Asist for XData; you may have already seen examples of it if you use ZEN or %Installer.Manifest.

We can use the %XGEN.AbstractDocument class for our task. Unfortunately, InterSystems has marked these classes (all of classes in %XGEN, in fact) as for internal use only.

Let's say the user need to execute some heavy code (build a report, or extensive calculations etc.). So, of course it needs to be asynchronous, and we possibly need to store some data about execution status. How?

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.595.0.

It may look like a slow week, with less than fifty changes having been checked in, but this kit includes the following fixes to problems found by you, the ones running the kits in the field:

• ALE2845, which fixes the cachejdbc.jar version
• JN1637, which fixes an issue that blocked debugging Atelier when used in conjunction with Kerberos
• DLP3508, which fixes a JSON issue with $compose()

The rest of the fixes have been spread among different areas of the product, chief among them DOCUMENT Data Model, SQL and Atelier.

Does Caché support a relationship property ordered according to a specifc value? 

What shoud be the best approach? 

The attached file contains an example of code generation using ObjectGenerators which builds a very simple homemade RuleEngine. 

Code generation is an excellent way of increasing performance moving run-time calculations to compile-time.

We could generate code creating routines or implemeting methods using ObjectGenerators. In this example we are using ObjectGenerators.

Update: Rule Engine is now on GitHub https://github.com/intersystems-ib/cache-iat-ruleengine

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

    set method = ##class(%Dictionary.MethodDefinition).IDKEYOpen($classname(), methodName)
    set args = method.FormalSpec
    for i=1:1:$length(args, ",") {
        set arg = $piece($piece(args, ",", i), ":", 1)
        write !, arg , " = ",  @arg
    }
