Studio supports an option to display arguments using multiple lines. Is there an equivalent option for Atelier? The Studio setting is under Tools->Options,  Environment->Class and is controlled by the "Multiline method arguments" flag.

Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.

Hi -

I'm trying to rewind a cursor back to the first row after looping part of the way through the implied result set, but I'm not finding a way to make this happen, is there some such iterator variable or directive that I can leverage to accomplish this?

I could code around it by pulling identifiers and/or values into a local array, and then hand code up an iterator over my local results copy, but this feels like a "redesigning of a wheel" approach, and I thought I would check before I start down this path.

Thanks

Job Description
Caché Objects Web Developer

An excellent opportunity exists for an enthusiastic Caché Objects full stack web developer to join our rapidly growing company based near Old Street.

The Job

Our customers use our software to manage events, from small meetings to high-profile conferences and shows. The quality of our software is critical to their success, and critical to our business.

The successful candidate will join our agile software development team and will play a key role in ensuring that we deliver great software to our customers.

If I wanted to build a web-based dashboard that monitored various HIE transactions where would I start?

Examples of measures would be Provide & Registers by Facility, Patient Views by facility or even PHR related data.

I have a successful POC that uses nodejs, html and SQL but I think it makes more sense to use Intersystems technology all the way around, I just don't know where to begin.

CSP for the web piece I assume?  How would I access the data, for instance all P&R requests on the BUS?  Any other tips or starting points?  Maybe examples of a similar project?

We do not have a DeepSee license

I can see mention of it online - http://www.intersystems.com/our-products/cache/tech-guide/chapter-3/ - but nothing in the docs on how to implement. Does anyone have any experience with this? We've managed to implement Hibernate and JDBC connections to Cache DBs fine (these are documented!).

Thanks very much :)

Customer is using an ancient MSM based client Workstation for their application and they made a small change to their server code. They introduced property of %Double() and discovered an issue. The MSM workstation is not able to retrieve any property of an object instance that holds value of $double(0). see images illustrating the issue.

I'm posting this to DC intentionally before I eventually send it to WRC so others can comment.

During recent large scale benchmarking activities, we were seeing excessive %sys CPU time that negatively impacted scaling of the application.

Problem

We have found that a lot of the time was spent in the localtime() system call due to the TZ environment variable not being set.  A simple test routine was created to confirm the observation, and the elapse time differences and CPU resources needed with TZ set versus TZ not set were astonishing.  It was discovered that the inherit use of stat() system calls to /etc/local_time from localtime() are very expensive when TZ is not set.

Hello,

I am looking for a routine or global that can help me see what is the  REST Operation output. Similar to  ISCSOAP for SOAP web services operation.

Thanks

Hi,

I am looking for a mapping from SDA collections to the HS Analytics (HSAA) data model. Specifically HS.SDA3.Container.Observations to the tables (Couldn't find all the fields in HSAA.Observation). Can someone help? Thanks

Let assume you have a infinitely scaling algorithm implemented in your application, using replication, ECP, or any other means of horizontal scaling, and let assume you know how to run your system under any volume of requests, the trick is to deploy required number of computing nodes in the cluster. If we are talking about cluster of 2-4 nodes your administrator (or as they call it today "devops engineer") will install anything manually. Probably he will easily handle 5 nodes configuration in the cluster. But what if you need to deploy 10, 100, or 200 properly configured, interconnected nodes?

Hello WRC.

Is possible to obtain a node-cache modul for the nodeJS ver.4.4.4. and actual Caché 2015... ?

And what is the expected outlook of this.

A note about this new portal: If I put into "search box" some text with dot like .js or .css ( for example: test.js )  , I obtaint error page. Try it.

Of course, this "Developer Community" is nice, the right way.

Nice day for all, Jan Krestyn

Hello,

I have a question about how to set the value of a radioSet.  Yes, I know -- the documentation says that setValue can be used "client side", but gives no example.  Plus, I'm trying to set the value of a radioSet in %onAfterCreatePage, which is a Zen method? Server side method? I'm not sure.

In my Zen page I create a radioSet like this:

<radioSet id="appRadio" name="appRadio" 
displayList="App One,App Two,App Three" 
valueList="One,Two,Three"/>

I want to select a radio based on a sepcific value, that I get from code.

e.g.

Method %OnAfterCreatePage() as %Status

set value = class.

Setting the TZ Environment Variable on Linux

The Update Checklist for v2015.1 recommends setting the TZ environment variable on Linux platforms and points to the manpage for tzset. This is recommended to improve the performance of Cache’s time-related functions. You can find out more about this here:

https://community.intersystems.com/post/linux-tz-environment-variable-not-being-set-and-impact-caché

The manpage on my CentOS 7 test system (RHEL 6 says the same) has this to say:

“The tzset() function initializes the tzname variable from the TZ  environment  variable.

Hello,

I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...

Is it possible to create a "lists/array/multidimensional 101" page for beginners?

Hi,

I am trying to use data transformation (DTL) to map a JSON to SDA. My elements in the source JSON is not one to one with SDA object. That means I have to add code to loop through these objects in order to complete the mapping. Can someone send me a sample that can look to create that? I am not very comfortable with scripting language used in Health Share. Appreciate your help.

Regards

Joseph

I was planning to fully map out all the transforms that incoming CCDs go through before they are displayed in the Clinical Viewer or sent back to another facility.  When I opened the XSL files, I see some very good comments like the following:

I am hoping some of you network guys have ideas. InterSystems seems to be at a standstill. When I startup Studio and try to start Terminal I get License Limit Exceeded. Starting with Terminal and going to Studio, same thing. It started when I put down a 2016 version of Cache on top of a 2015. InterSystems told me to uninstall everything and start fresh. I did that but have the same problems. What can I look at? How do I start to debug this? Although I am the only one on my PC it is really impacting my performance.

-thank you

Hi,

Using cube CubeA and cube CubeB that contains calculated measure TotalClients.
I would like to use TotalClient calculated measure from a compound cube CubeC (CubeA,CubeB).

How would you do that?

Hi All,

I've created a sample implementation of the MQTT protocol, which is now available on GitHub. 

The project demonstrates MQTT client capabilities and it's written in Caché Object Script.

Any comments, bug reports are welcome! Some more enhancements (like SSL / TLS support) are planned for the near future.

Introduction

The field test of Caché 2016.2 has been available for quite some time and I would like to focus on one of the substantial features that is new in this version: the document data model. This model is a natural addition to the multiple ways we support for handling data including Objects, Tables and Multidimensional arrays. It makes the platform more flexible and suitable for even more use cases.

Occasionally I see a production item with a little 2 flag.  When it has that, there is an "Item" dropdown.  What does this mean?

Hello!
Are there any short ways of serializing COS entity to the string? I am searching for something like .$toJSON() , but I need Caché 2013.* support.

The one way I supposed to work is to use $listbuild:

set str = $LISTTOSTRING($LB(1,2,3,",",5))
set list = $LISTFROMSTRING(str,",")
zw list
list=$lb("1","2","3","","","5")

But the problem is that $listbuild does not escape delimiters, and it is not possible to deserialize serialized string. The structure I need to serialize may contain any characters.

Are there any short ways to do this in Caché to avoid writing custom parser?

I need to pass multiple values to a FILTER to a DeepSee DASHBOARD via the URL. The documentation seems to indicate this can be done, i.e.: "Where each filterspec is filter_name.filter_values" but there are no examples I can find that indicates what is used to separate multiple values. Say I want to pass the three values 5, 6, and 1395 to a filter. To pass just the 5 I know this works:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5

but how do I include 6 and 1395. None of the following seem to work:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5.6.1395

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.

this is catching  me all the time, again and again...

Haven't worked with XML VDOC for some time, I can't figure out, what is the correct way of using Property path. Can someone please help me to refresh my memory.

Simple example: I have a class called Body, with Value and Topic properties. I created a XML Schema for this class and imported it into Ensemble. So i have a category called message, with Body as DocType structure and Name and Topic properties of Body complex type ($2:Value and $2:Topic are element names)

My rule looks this way:

However, the rule is ALWAYS evaluated as

When using the "XML Cache Script" export via the Export context menu option (right clicking on a class in the Atelier Explorer View) sometimes the export dialog is empty.

Other times it is pre-filled with the project selected and the individual class chosen as expected. When it is blank you can choose the project but within the list of all classes there is no package hierarchy making it difficult to find your class.

Anyone know why sometimes you get the empty selection and sometimes you don't? I've tried to reproduce it at will but can't pick up a pattern.
