Caché and Ensemble 2016.1 Release

New Book, Caché and MUMPS – Part II

Hi!

Does anyone have an example of subj?

I know there is google service for it. Anyone uses it in production? What is the feedback?

In case of positive feedback would you please post the code example?

TIA!

Hi

I have been experimenting with the creation of a set of REST services for an app. The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return. However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)

Hello.

For debugging purposes I sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !
    }
}

And to save stack to a global there's always an exception method:

Hello,

I am experimenting with the iKnow Domain Architect in the 2016.2 field test.

I would like to know if it is possible to load metadata from text files. This was possible in previous versions, using the Loading Wizard.

I have checked the documentation and I do not see any explanation for loading metadata held in text files. Thank you!

If you are waiting for the Kindle Edition of Caché and MUMPS – Part II, I must apologize. I believed what others told me that once I have a book manuscript, the Kindle manuscript will be easy. Being a programmer I should have remembered: "never assume anything." The conversion to Kindle is proving a much bigger task than I thought. But don't lose heart, I am working full time on it. I have as my goal before May 1^st. But, then again, you know what they say about goals. ;) - - Paul Mike Kadow

In Atelier when resolving conflicts with the server the screen shows the Local copy and Server copy and the differences, but depending on where the difference is you cannot tell what what the document is, you need to scroll to the top to see what it is before deciding what to do. It should indicate the class or routine name beside "Conflicting Server documents"

At the end of this year support for OpenSSL 1.0.1 will end. InterSystems has started the process to move to OpenSSL 1.0.2 and use the 1/28/2016 release (1.0.2f) for verification and product inclusion. I will update this post once InterSystems decided which versions will receive support for OpenSSL 1.0.2.

We need to add some stored data to an ACK message being sent back to the originating system. I have been looking at how to adapt the standard "EnsLib.HL7.MsgRouter.RoutingEngine" to do this as I cannot see any obvious way. Any suggestion?

Version: 1.0.123

Cache for UNIX (Apple Mac OS X for x86-64) 2016.2 (Build 619U) Thu Mar 17 2016

After deleting a class on the server, Atelier still wants to believe it exists. I even deleted the project and the server. After re-creating them, it still believes the class exists. I log in with studio and it shows the class has been removed.

If I attempt to open the class in the server explorer, I get a null pointer exception, but I can open any other class.

Any thoughts would be appreciated.

An XML-enabled class has an XMLExport() method that knows how to serialize an instance to XML. To export all instances of a class to a file, I need to instantiate a writer and loop through the extent. Is there no class method like XMLExportToFile() that does this in one go?

I am happy to announce the immediate availability of Caché and Ensemble 2016.1.

The highlights of 2016.1 are

• Significant improvements in JSON support
• Continued advances in SQL performance
• Database scalability improvements
• New REST services for DeepSee

These and other new features are summarized in this video introduction to 2016.1

For complete technical details of what’s changed in 2016.1, review the Caché release notes and the Ensemble release notes.
