Hello, guys. 

I found one interesting moment in Cache Object Script. It doesn't have(or at least I didn't find) trimming function. By trimming I mean if a string has some whitespaces/tabs/carriage returns from very beginning or/and from very right, this function removes them. 

  I have found several workaround ways. 

1. Using Cache Basic

ClassMethod TrimCacheBasic(str As %String) As %String [ Language = basic ]{Return Trim(str)}

2. Using SQL

I saw someone recently refer to ECP as magic. It certainly seems so, and there is a lot of very clever engineering to make it work. But the following sequence of diagrams is a simple view of how data is retrieved and used across a distributed architecture.

Hi All

I have a question on working with dev and prod environments.

After project is ready and signed, I usually migrate outcome to production using the export tool from the studio.

For changes/adding to existing projects, I exclude the production class (as it has some different values differing the dev from the live) and I add the differences manually afterwards.

My questions on migrating are:

Does anyone has (to share) his/her best practice steps on "migrating dev to prod"?

Does the export action (in management portal) is better to use?

Thanks

The article is a step by step guide for beginners to learn how to build a RESTful web service consumer (or client) in Ensemble. The provider can be any RESTful service, but the example is based on the service we made during the previous sessions.

I'm following the tutorial here.  When I try to call the default Test() method I get the following error:

An error occurred with the CSP application and has been logged to system error log (^ERRORS)

I found this document which says I need to make the "Web Application" accessible by running a couple commands.  I'm not even sure I created a Web Application.  Regardless, I tried a few variants but still get the same error.

Here is the URL for the Service Catalog: /csp/healthshare/mhclib/Custom.MHC.Scott.ServiceTest.cls

I tried different things including these two:

Checking if Directory or File Exists:

Outlined below is an example of how to check if a directory exists:

Set directoryName="c:\temp\nosuchdir"

/* Check for existence of a directory - Return Value:  0 - directory does not exist;  1 - directory does exist  */

Set directoryExists=##class(%File).DirectoryExists(directoryName)

If ('directoryExists)  // do the processing for when a directory does not exist

Outlined below is an example of how to check if a file exists:

The one question that some of you might have is:  

How do I change my login information for Cache Studio if I clicked the checkbox to automatically save my login info so I do not have to enter my username/password every time I open Studio?
 

Well.....excellent question!!!!!!

Here's the answer:  

Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass

Looking at the posts, I cannot find a simple way to show everything in DATE order (newest first).

when I click on "NEW", It's 11:26am (UK time) and the first few entries are

Date/time seems to bear no relationship to the order.

I want Healthconnect to be the middle man between my client and my respository vendor. I've setup

HS.IHE.XDSb.RepositoryServices > HS.IHE.XDSb.Respository.Process>HS.IHE.XDSb.DocumentSource.Operations

Is this the correct approach?

I have a class with a string property with DISPLAYLIST and VALUELIST parameters specified.

When I query this class via ODBC I receive logical value as it is and not a display value.

Is there any way (without stored procedure) to get display value?

Hello,

I think it will be very useful to add the following information about community members:

-Full Name (that is the only thing we see today)

-Company

-Title

-[Optional] Areas of interests/expertise 

This information should help the community members evaluate the credibility of posts and responses.

Thanks,

In Subscriptions > Overview >  I checked Digest Mode, which is defined as:

"Merges your notifications into a single email, sent at the interval you specify. "

Under Preferences I set the Send Interval to be Daily.

I receive a couple dozen emails each day.  They all have a subject of "Subscription Digest for..."

Each email only contains a single item, so it doesn't appear to be a "digest."

It clearly is coming more than once a day, so doesn't appear to be following the set Send Interval.

Is this a bug or am I misunderstanding the settings?

I need to do an UPDATE via SQL and I would like the statement to return the `ID` column of each row that is updated.  MS SQL has an "OUTPUT" statement, but I don't see anything similar in Cache.  Is there a way to do this?

Anyone has already been successful in connecting google calendar to Ensemble ?

Have you tried $Translate for date conversion?

USER>write $Translate("Dd.Mm.WwYy","WwYy-Mm-Dd","2015-08-02")

Stolen from Russian forum and Alexander Koblov.

We are using object EnsLib.EDI.XML.Document and the method OutputToString -- ( context.XMLObject.OutputToString("C(utf-8)") ), In the string that we get back, Hebrew characters are unknown and we get question mark instead.

How can we overcome it?

Is the possible for Multiple Streams using in single method?

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

NewBie's Corner Session 29 Documentation on the Caché/MUMPS Global Structure

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

This post contains several links to very good documentation of the Caché Globals Structure.

Like I said, "Perhaps the most difficult concept in Caché/MUMPS is its Global Structure."

 Windows 7 and some other Microsoft Operating Systems can shutdown too fast for large applications, such as a Cache instance with a large amount of data and changes, to close gracefully. This results in the instance being forced down by the OS and so causing problems on the next start up.

To solve this we can change the OS shutdown timeout values to give Cache more time to close gracefully. We do this by editing some settings in the Registry.

1.Click Start (on Win 7) and type “regedit” and make sure you run registry editor as administrator.

Hi All,

We are Using Ensemble 2014, Windows Server 2012 64 bit operating System.
We need to sense whether Htpps is alive or not.
In Cache we tried %HttpsRequest Library we set https property and port=443. But it doesn't work.
Anyone help us plz.

Thanks, Sansa

We're developing Ensemble PoC and one day our frontend developer (who doesn't have Ensemble production running) said that Populate just doesn't cut it and he needs to see the real data. He needed only one object, but the problem was - it's a big object. Still, I checked ids of everything related and wrote this command (parts omitted, but you get the idea):

I tried to get a image from user . But It did not run. So please solve this problem

Class Quadramed.Chennai Extends %Persistent
{
Property Image As %Stream.FileBinary(LOCATION = "C:/Images");
Method imagefile()
{
s obj = ##class(Sam.binary).%New()
r "enter your name",img
d obj.Image.Write(img)
s status = obj.%Save()
}

NewBie's Corner Session 1 Installing Caché

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Session 1 - InterSystems Inc. allows you to download a single copy of Caché to your personal computer at no cost. This is available from www.InterSystems.com.  It is at this link: https://download.InterSystems.com. You will first need to register yourself with InterSystems. Follow the instructions on how to download the install file. Choose the full version of Caché, not the Client Components.

I know per documentation (pasted below) to set the DSTIME parameters for the base class of a cube.  If that base class has a property that is another class, do I have to add the DSTIME parameters to that secondary class? 

Documentation says the following in a section titled "Enabling Cube Synchronization:"

Before you can synchronize a cube, you must enable the cube synchronization feature for that cube. To do so:

1.   Make sure that cube synchronization is possible in your scenario. See “When Cube Synchronization Is Possible,” earlier in this chapter.
