Hi,

I am working on a DataGrid based upon ZenTest.Datagrid.cls

I want to save data after changes on a row.

The existing samples do not explain how to save changes on data in a grid.

I have tried something like zen(‘json’).save

Does anybody has some sample code?

I have a production system that has a large dataset of about 2 million rows. I need to create an index on a property but don't want it available to queries until the index is fully populated. Is there a way I can create the indexed, fire off the build, then "activate" the index so queries can use it.

The problem I face is the minute I create the index queries start returning zero rows because it starts using the index.As I start building it starts returning qualifying rows for those it has indexed but misses those not yet processed.

I am just trying to make a quick hand off HTTP production.I have the class built and compiled onto the server and the production is running as a service.When the production is called (by an inbound job) I can see that the HTTP.InboundAdapter is being used successfully and the stack continues all the up to ProcessInput where OnProcessInput is called in Ens.BusinessService.

Announcing EWD 3:

Currently if I accidentally rate article as 4 I cannot change my vote.

Personally I'd prefer just +/- under the article.

There is thin line between 3 and 4 for the article or 2 and 1. Like/dislike is better in my opinion.

Ability to view content by particular member is a great feature.

I'd like to propose some enhancements to this:

• Member content should be accessible from member page. For example, under separate tab.
• There should be possibility to follow member. For example, I want to be notified every time Evgeny Shvarov posts something.
• On member content page we should be able to filter by comments/posts/all content.

UPD: I found separate topic for first item of my list: https://community.intersystems.com/post/show-users-posts-user-page

Hi,

Assume an architecture where an ECP Database Server is connected to by one or more ECP Application Servers inside a firewall.The application server hosts the web application that web users connect to.

The Web servers are outside the firewall, and, (using the CSP gateway/server mechanism) issue requests over the SuperServer port and into the application server.

I know that the traffic between the Web Server and the ECP application server can be encrypted using HTTPS, and access to the CSPServer on the Application server is username/password secured.

Q1: In order to bolster security, is it

This article is about DeepSee Listing Groups, a new DeepSee feature that was introduced in release 2015.2.

DeepSee Listings have always been a part of DeepSee.  DeepSee Listing Groups provide increased flexibility by allowing you to create new DeepSee Listings without modifying the cube definition.

Hello,

is there any API available that would return an MDX query string for a given saved pivot name? I could not find anything except for pivots with manual MDX. But that's not my case, I need to get MDX for any pivot.

TIA!

Hi ,

In HSBUS we have out of box operation HS.IHE.XDSb.Repository.Operations to route CCD's from HSBUS to Edge gateway.

Earlier it was working fine, but for maintenance we have to rest the DEV environment, Now its throwing below error. I have verified all registry configuration and the CCD feed is also same, nothing is changed except reset. Can someone help me, where to look for this problem or what I am missing here.

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit.  I'm wondering if there is anything similar for HL7v3/CDA/CCD.  I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/.  I'd love to hear anyone else's tips for tools or resources.

We are receiving XML documents and storing them. When we click to go into the clinician portal and again to view a patient, we can see the documents but none of the data is mapped to their respective buckets, i.e. allergies or medications.

I am thinking that I need to build an XSLT parser and change the format to SDA3, is this an appropriate approach? Or would using the Data Transformation (Ensemble -> Build -> Data Transformation) be a better idea? Lastly, if the XSLT idea is preferred, where would I call it within the stack?

Hi community!

Does anyone know if it´s possible to override a property name to generate a JSON message based on the instance of object?

Hello there Intersystems Developer Community,

This year while at the Global Summit, I came to learn of a component that Stephen Morrison of Intersystems had written that was capable of infusing SVG content into a PDF document.  Apparently Stephen was approached about this and was amenable to sharing the code with us as we have recently encountered a similar need.  I'm hoping this post will lead to the sharing of this utility code, so that we can determine if it will indeed suit our need.

It is my impression that this code is maybe that being used to perform the print operation on a given widget

Hello friends,

Does anyone know how to make the default checked for the 'Open as read-only' setting in Caché Studio version 5.0?

Find out about the various ways you can learn Caché. 

Steve Glassman is on vacation today so in his place I wanted to announce the availability of a new kit for the 2016.3 Field Test. The kit details are: 2016.3.0.628.0

Most of the changes are related to DeepSee, DocDB data models and dynamic objects. You can find a complete listing here:

Java Business Services and Operations

In Ensemble 2016.3 ‘Java Business Hosts’ provides the means to create new Business Services and Business Operations using Java without need for any ObjectScript coding. There are two major reasons to use this capability:

•  Add new protocols to Ensemble using available Java libraries.
•  Allows Java developers to create custom business services and operations without needing to learn Caché ObjectScript..

At Global Summit there were two sessions and an experience lab covering Java Business Hosts that got a lot of attention and a very positive reaction.

If I have a cache.dat file from a Windows 2012 (64-bit) machine and I want to mount it on a Caché instance running on RHEL, will it work? Assume the versions of Caché are the same.

Hello, I'm new to Ensemble, and my first task is to become familiar with the Production and create a basic outline of it for the users to view (which servers, where are the input files, where are the output files, how many records...).  What are the Production tables?  I'd like to start there.

Thanks,

Hi.

I'm facing a problem when I try to use the Runtime Expression below inside the XData Contents:

<html>#($$$Text("Testing!"))#</html>

It compiles correctly, but when I open the page on the browser I get the message "Expression Error" instead of "Testing!".

How could I use the $$$Text macro with Runtime Expressions? Is there a way to make this?

Thanks!

Post updated in August 2025 to include links to IRIS.

I have seen customer problems where the use of a virus scanner running over Caché or IRIS databases was causing intermittent application slowdowns and bad user response times.

This is a surprisingly common problem, so this short post is just a reminder to exclude key Caché and IRIS components from your virus scanning.

Generally, virus scanning must exclude the CACHE.DAT or IRIS.DAT database files and the InterSystems binaries. If an anti-virus is scanning *.DAT files and other InterSystems files such as journals and binaries, then system

Hello, one of our application partner, is considering modernizing their old CSP laboratory portal by using Zen Mojo with Bootstrap. They have a lot of experience with COS, CSP and some ZEN. They are new to REST/JSON and have some limited knowledge of javascript - perhaps not enough to the extent used by client framework. 

They are trying to create their portal main page with header and footer fixed where at the header level is going to have a menu or navbar and at the footer level they would like to have some options (buttons, search options, text, messages, etc) dynamically loaded during run

NewBie's Corner Session: 5 Operator Precedence

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

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Order Precedence means the order in which mathematical operators are executed. In a Mathematical expression, you may have Multiplication, Addition, Subtraction, and Division. Which of these are executed first, second, third, etc.?

The basic Operator Precedence of mathematics is:

       Multiplication and Division has precedence over Addition and Subtraction

When I goto the main developer community page:

https://community.intersystems.com/

When I turn on network monitoring this root page takes over 6s to load, this is with the other pieces of the page already cached on a nice fast network connection, the by the time the other requests are made it is at around 6.7s! A few other attempts were slightly better at around 5s. By comparison if I look at stackoverflow.com I see the browser completely done in <1s, the content itself takes just 433ms.

How can be get this >6s down to something a little more reasonable like <1s, even 1s is pretty slow these

Has anyone tried to extract a Microsoft SQL Image Column into a JPG file using Ensemble? We currently have a Microsoft SQL Integration Services job that exports a SQL Image column into a JPG and then resizes it. I would like to get this job off of Microsoft so the rest of our team can support it and wondered if we could do it in Cache Object Script using Ensemble.

Thanks

I need to call Ensemble Business Operation by sending authorised (basic auth, cache user) HTTP request (REST-like). How can I achieve that?

Maybe configure a Business Service, but which one has this functionality?
