dotnet core

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter.

Issue is ObjectScript.


1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

For CachéQuality I'd love to be able to create issues when the programmer uses classes which are deprecated for this or that version of Caché... But short of reading all the changelogs of all versions, I can't really tell when a command appeared (for instance RETURN; I know now that it appeared in 2014.x, but it took me some time to realize that), or when a (set of) class(es) became deprecated (for instance %GlobalCharacterStream to be replaced with %Stream.GlobalCharacter -- I don't even know since which version this is true :/).

Hi Friends ,

We have requirement to convert source hl7 message to target json message using dtl.

Currently I have created persistent cls for json and completed the dtl.

DTL giving output as json equivalent xml.

Now how to convert DTL result xml object to json?

Market penetration

My understanding is that IRIS is a new technology and does not replace Cache or Ensemble and to that end is more of a modernization than a repackaging. Is that accurate?

Is IRIS and HealthShare heavily penetrated in the payer space of primarily dominate in the provider space? What is the trajectory for InterSystems to penetrate the payer landscape?

When I try to open a DTL in the tabbed editor I always get this error:

You are using Internet Explorer 7. This version is obsolete and is not compatible with diagram editors. Please update Internet Explorer to a recent version.

My actual Internet Explorer is version 11.

I'm running Eclipse Photon.

Atelier IDE 1.3.141 InterSystems Corporation

The same error occurred with Atelier 1.2 on Eclipse Oxygen. I've never been able to get this to work.

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?



Let's say we have two globals:




i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

Is there a function in Atelier that's equivalent to Studio's "Find in Files"? Namely, to search for assets containing a given search pattern across an entire namespace -- not just across files that are currently in the local project.

I've been playing with the search functions in Eclipse, and so far haven't found a combination of options that will search against assets that are only on the server -- I can only get results for assets that are already in my workspace.

Cluster deployment recipes?

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.

Hi, Community!

How do you store the source files of your Caché project? What is the directories structure? What are the benefits?

I prefer the following structure:








  • folders are packages.
  • easy to understand what type of sources are in the project.

What is your approach?

As part of our security standards, we can't have our applications saving our credentials. For Atelier, this means our server connections. Is there a way to stop this by saving the connection parameters, but prompting for credentials on each run? Or is there another way?

Thank you
