Is there a way to query the database structure?  In SSMS there are queries for finding tables with a column with a certain name (using LIKE).  And there is the redgate tool SQL Search.  But I'm not sure how to go about looking for columns that have say a value of 'PATID' and returning all tables that match.  Does anyone know?

Allow a question from a newbie 

1. Lets assume we have a global (matrix) [X,Y,Z] that is distributed across sharded nodes
2. Matrix size doesnt matter, but lets assume it holds 500 GB for the moment
3. I want to return all rows where f(x,y,z) is true. f() is an arbitrary function, i.e. f = x + 20(y*y) > z

Questions
Q1. Can such a computation (in ObjectScript) be moved and distributed from the client to the different sharded nodes for parallel processing
Q2. Where is that documented (incl. perhaps an example and performance measurements)
 

Thanks a lot
Frank

Maybe I haven't seen anything about it in the documentation, but why isn't there a way to list all the Resources from the %SYS namespace from a class rather than through ^SECURITY

Thinking maybe something like this: 
##Class(Security.Resources).ListAll(.result)

In one of my class, I use Stream.Read() method of the %Stream.Object class.

• Method OnRequest(request As Ens.StreamContainer, Output response As %Library.Persistent) As %Status
• {
•    SET sc=$$$OK
•    SET strRequest=request.Stream.Read(,.sc)
• ​​   $$$TRACE($L(​​strRequest))
• ....  

The Trace value gives 32,000. But the Read() method of the %Stream.Object class specifies 32,656 by default.

1. Method Read(ByRef len As %Integer = 32656, ByRef sc As %Status) As %CacheString
2. {
3.    Set len=0,i%AtEnd=1,sc=$$$OK
4.    Quit ""
5. }

Why ?

Best Regards.

Hi developers!

Suppose you have a Github repository with ObjectScript classes but without a Docker environment.

Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.

So in one sentence:

Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!

See the details below.

Temporary tables are tables available for a current process only (and destroyed when process ends).

What are you approaches to creating temporary tables?

1. Process-private Globals storage can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage.  Here's how. Here's how 2.
2. InterSystems TSQL supports #tablename temporary tables. A #tablename temporary table is visible to the current procedure of the current process. It is also visible to any procedure called from the current procedure.

Hello Everyone , Good Day ! I have a question regarding the implementation of USCDI (US Core Data for Interoperability).

Why USCDI was introduced? What is the disadvantage of previous process ( communication between systems using concept like HL7) ? What is the impact of implementing this concept in existing systems ? Do we have to change logics for processing the messages? Will it effect the existing work flow of all the healthcare application?

Hi,

I want to know if anyone tried calling a CDS service from Healthshare/Ensemble. Will that be similar to any other API or is there anything different in constructing CDS Hooks and consuming the CDS Cards received in the response? 

Greetings Developer Community!

InterSystems IntegratedML (formerly known as QuickML) is ready for external beta, and is looking for some users to kick the tires!

Just like the title says, I'm attempting to find a way to create a web application that instead of serving CSP files, it uses a dispatch class.
I searched for clues in the documentation, but the CSPApplication tag seems to be exclusively for CSP file-based applications.
I'm trying to avoid implementing a workaround such as using the Invoke tag to call the Security.Applications to generate the web application but I might be forced to do so, even though it's unpleasant if I had to say...
So, is there an official way to execute this task?

Hi All,

I need to build a search using a lot of filters, what's the best way to implement my sql requests.

1 sql request per property, or only one "big" sql request ?

what's the disadvantage of using lot of indexes ?    Thank you

KR,

Amine

In Episode 5 of Data Points, @Bob Binstock joins us to talk about mirroring databases for high availability in InterSystems products! Most of the discussion centers around this process in InterSystems IRIS, with a few notes about the differences when tackling it in HealthShare. Take a listen and let us know your thoughts!

This message contains five recent HealthShare Advisories, which are available below.

There does not seem to be any separation between the error code and error text in a %Status object. For custom errors, I simply want to display the message and not Error #5001: Some error text.

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions. While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue. Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours. I did not find any way, how to get the list of the open transactions from one place from ECP Data Server. We just migrated our Data server to 2018.1.

Hi

We are trying to use Ensemble as a Router for DICOM Worklist. So when a DICOM Client sends a request (ECHO Or C-FIND), We want Ensemble to carry such request to Epic EMR. When Epic EMR responds with a Response, We need to be able to forward that response back to DICOM Client. I wanted to see If anyone has a working example of this scenario. 

Examples we have in DEMO namespace are not entirely falling into this scenario.

Hi All,

I'm having an issue where I try to use  SOAPUI for a mockup offline service, my issue is when I have the mockup service running in the background and try to send a request from cache I keep getting the following error: "ERROR #6454: No supported policy alternative in configuration".

I've tried to follow the common guidelines for resolving this issue but no luck.

So if there is maybe a nice article explaining how to send a proper request to the mockup service and then getting the response(which will be hardcoded values I've set).

I'm working on developing Productions with java. The sample project has several intersystems jar files: -- intersystems-enslib-jms-3.1.0.jar -- intersystems-gateway-3.1.0.jar -- intersystems-jdbc-3.1.0.jar -- intersystems-spark-1.0.0.jar -- intersystems-uima-1.0.0.jar -- intersystems-utils-3.1.0.jar -- intersystems-xep-3.1.0.jar

I have the jar files, but where can I find them for download? Are they available on a maven repository somewhere?

Any help would be appreciated!

Is there a helper class available that will import an XML class and convert the class to UDL?

Hi Everyone,

I've been working on deploying an IRIS for Health environment in EKS. There is a video session in the InterSystems learning portal about this feature but I have not succeeded in finding the proper documentation and resources to use this in my Kubernetes cluster.

Has this been deprecated/discontinued? Any idea where can I find the resources? Should I stick to StatefulSets instead of using the IrisCluster resource type provided by this operator?

We're working hard to bring you the learning content you need -- help us by taking this 2-min survey to tell us what you're looking for!

Can anyone clarify to me about the differences between these two classes?

People in this topic https://community.intersystems.com/post/using-class-queries-sqlstatement-versus-libraryresultset stated that %SQL.Statement (I am assuming they mean to talk about %SQL.StatementResult) is newer than %Library.ResultSet. But I don't really know what are the advantages of %SQL.Statement over %Library.ResultSet as the people in the topic somehow didn't mention them.

Currently I have a case and it seems like the %SQL.

just wondering - is there any reason why IRISList doesn't accept decimal values?

.. IRISList would be very handy und useful - but if i have to build a wrapper to serilize/ deserilize decimals ...

Last time we launched an IRIS application in the Google Cloud using its GKE service.

And, although creating a cluster manually (or through gcloud) is easy, the modern Infrastructure-as-Code (IaC) approach advises that the description of the Kubernetes cluster should be stored in the repository as code as well. How to write this code is determined by the tool that’s used for IaC.

In the case of Google Cloud, there are several options, among them Deployment Manager and Terraform. Opinions are divided as to which is better: if you want to learn more, read this Reddit thread Opinions on Terraform vs. Deployment Manager? and the Medium article Comparing GCP Deployment Manager and Terraform.
