Question Oliver Wilms · Nov 22, 2024

I finally figured out how to get JWT token using set x = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("medbank","openid fhirUser",.prop,.err).

I also found iris-fhir-client app on Open Exchange. I registered Epic sandbox server, but I cannot list resources. I suspect I need to integrate authorization / authentication. How do I do this with irisfhirclient py?

Production Configuration

This demo has an interoperability production with 16 items. 

Production Configuration HL7 + Kafka Producer

The first part of this demonstration consists of sending an HL7 SIU file which will be transmitted to the 2 other HL7 flows (HTTP and TCP), and transformed and transmitted to the Kafka server. HTTP and TCP flows will transform HL7 messages in the same way before sending them to Kafka as well.

  • 3 HL7 Business Services
  • 1 HL7 router
  • 2 HL7 Business Operations
  • one Business Operation sending the transformed messages to Kafka

Is anyone using Veeam as their external backup product?

I'm trying to backup a Linux VMs (VMWare; SUSE).

These VMs have a mirrored pair IRIS DB.

I'm using the InterSystems's provides pre-freeze - Backup.General(ExternalFreeze)
I'm using the InterSystems's provides post-thaw  - Backup.General(ExternalThaw)

I've been running the backups with Veeam 'application aware processing' so I can add the pre-freeze and post-thaw scripts.

I'm backing up the PRIMARY node of the mirror pair.

The problem is that the time take by Veeam between the run of the pre-freeze script and post-thaw script is about 14-16

I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.

Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?

Thanks

Question Claude Mourzelas · Nov 13, 2024

Hello,

I want to upload a "custom" metric in prometheus (queue).

For now, in version 2022, I have the impression that we cannot add multiple labels and yet the basic metrics know how to do it.

ex: standard metric

iris_interop_messages_per_sec{cluster="1", host="xxxx", id="API", instance="xxxx:80", job="SAM", production="xxxx"}

my current example: I would like to be able to at least add the production, just to have the source of the measurement.

my_iris_queue{cluster="1", id="xxxx", instance="xxx", job="SAM"}

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2G…

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

The header and payload are then base64 URL encoded, combined with a period separating them, and cryptographically signed using the private key to generate a signature.

I attempted using this

When building a bundle from legacy data, I (and others) wanted to be able to control whether or not the resources were generated with a FHIR Request Method of PUT instead of the hard coded POST.  I have extended the two classes responsible for transforming SDA to FHIR in an Interoperability Production to accomodate a setting that lets the user control the Request Method.

First is the Busines Process class. This includes a new parameter exposed to the "Settings" tab in Interoperability called FHIRRequestMethod.

Question Dmitrii Baranov · Nov 12, 2024

To transfer data between production components I actively use messages of type Ens.StreamContainer class and its descendants. In many cases the content of the message content is not visualised (the 'Body' tab contains a table with a list of selected message properties but the 'Contents' tab is empty). Response messages are never visualised, and request messages are visualised with a fifty-fifty probability. What do I need to do to ensure that messages are always visualised?

Question Dmitrii Baranov · Nov 17, 2024

I'm playing with some anayltic queries against FHIR server tables. The HSFHIR_X0002_S_Patient.addressCity table contains a lot of cities which names contain german charachers such as ä, ö and ü.

The following query works fine:

select value from HSFHIR_X0002_S_Patient.addressCity

But this one converts city names to uppercase, and characters with umlauts are lost, so instead of "Köln" or "München" I see KOLN and MUNCHEN:

select ac.value, count(ac.value) as cnt
  from HSFHIR_X0002_S_Patient.addressCity ac
  group by ac.value
  order by 2 desc

I'm using DBeaver with IRIS official JDBC driver.

Is there a way to create and establish DICOM Association with Extended Negotiation? 

I have implemented DICOM Query/Retrieve C-FIND, using EnsLib.DICOM.Operation.TCP and EnsLib.DICOM.Process base classes. My application, acting as an SCU, needs to query by Study Date-Time (combined date-time matching) range with timezone query adjustment. For this, I need to use Extended Negotiation.

I've checked the IRIS Manual - Creating DICOM Associations section but there is no mention of this.

InterSystems FAQ rubric

By default, the order of columns in a table is determined automatically by the system. To change the order, explicitly set the order for each property using the property keyword SqlColumnNumber when defining the class.

Example:

Property Name As %String [SqlColumnNumber = 2];

Please see the documentation below.

SqlColumnNumber

If you want to change the SQL table name, specify SqlTableName. If you want to change the column name (field name), specify SqlFieldName.

Both apply only to persistent classes.

I'm trying to get the python external language server started up in a container I am starting. The container is up and running but I cannot get the python language server to start.
This is the error that is coming back when trying to start the language server. I have tried creating a custom image with that package installed but it still does not work. Is there something specific that needs to be done to to get this working? (FYI, I have the dotnet version working but creating a custom image and installing the dotnet runtimes via a docker file)

I'm trying to rewrite a legacy portal created with all .csp files into a portal written in .cls files. The problem I have is that the old cap pages use "csp:include page='page.csp'> tags. I'm trying to use the Include method  that is in the %CSP.Page master page. It doesn't seem to insert the required file. Any suggestions?
 

<table width="100%">

Question Nicki Vallentgoed · Nov 8, 2024

Intersystems provides External language server connections for various languages which,
from a development perspective, is great as I can keep my application code separate but still interact with the IRIS kernel.

It becomes more complex though if you are using Interoperability etc where you might end up with some code in IRIS and some code in another language.
What would be great is having an IRIS to IRIS language server where the application code and stay IRIS based but separate from the database?

I hit halt in Iris lite terminal within VS Code and was exited out to PS prompt.  I was just curious what the best way / recommended way to get back into an InterSystems lite terminal would be?  Perhaps it is just to start a new InterSystems lite terminal from a the options listed previously in this post https://community.intersystems.com/post/how-run-objectscript-commands-v….  I was just curious if there was a way to kick it off again from the PS prompt?

Hi guys,

Is it possible to apply business rule on a XML without Schema?

Say, I'm trying to make some business rules on FHIR XML payload. I transferred the XML stream as an EnsLib.EDI.XML.Document in a BPL and passed it to a General Business Rule.

Set context.xmlDocument = ##Class(EnsLib.EDI.XML.Document).ImportFromLibraryStream(##class(HS.SDA3.QuickStream).%OpenId(request.QuickStreamId))

I'm handling following XML document 

With this rule

Then I got stuck at visiting the elements in the XML.

I.e How may I evaluate the profile value?

Thanks。

Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.

Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.

After some time, we stumbled upon the GetMutableSegmentAt and GetSegmentAt methods and plugged the mutable method in its place and what do you know, it worked!

Question Elisha Gould · Nov 7, 2024

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.

An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.

I'm looking at possible ways to help

Hello Community,

I have a stream property which uses %Stream.GlobalCharacter and I set some dummy texts like "a1a2a3a4a5a6a7...."(more than 1024 characters)   in to that stream and the stream values are not compressed. However, The streams are compressed If I use the Lorem ipsum is a dummy or placeholder text or other text "This is part four of a long memo." which length is greater than 1024 

I opened the stream object and confirmed the compress property is 0 for first entry and  1 for 2nd object

I'm working on my first (!) IPM module and I'm a little puzzled with the registry authorization.

I have a working local registry (I hope!) and the module is loaded (with load-command) to the namespace.

Now publish-command fails because of missing authorization. I have set nothing authorization related myself and I'm lost how the authorization should be configured. All the material I have read so far seems to ignore that and only mentions one have to authenticate ...

Here's the command output:

zpm:IPMTEST1>version

%SYS>     zpm          0.7.3
IPMTEST1> zpm-registry 1.3.2

Hello,
Please, we would need your help 🙂:

In a development environment, we have added quite a few presentation contexts to the DICOM configurations (the associations). We would need to find a way to export them from this environment to make it easier for us to import them in PRO (and avoid doing it by hand one by one).

We know that there is this method, the ImportAssociation(), that given a file, and the names of the local AET and the remote AET, creates it automatically:

Question Robert Stephens · Nov 4, 2024

I'm running a query, joining nine tables together. When I run it with a SELECT COUNT(*) I get about 200,000 rows. When I run the SELECT with the columns I want, I get about 2,700 rows. Is there something inherent with the queries that limits the result set size, or anything I can do to make sure I'm getting back all the results? Rather, than trying to run it about 100 times limiting all previously gotten accounts.
