I'd like to ask you for recommendations on how to properly use repository dependencies when using VSCode and Client-side editing. Suppose I have projects A, B and C, with A being independent, B depending on A, and C depending on A and B. I am currently working with the main project C, and I want to be able to contribute to all the other projects in a single VSCode window (instead of opening three instances). How do you solve this problem? Git submodules? ZPM? Something else?

We are receiving the report in text format and it has special characters like ', - like that in the text. Source system is using the UTF8 encoding format hence the text is showing as ' � ' . Is there a way to convert the utf8 to actual character in the DTL.

Thank you,

I have a business service which is responsible for some batch operations with an SQL table. The process is generally slow but it is possible to scale the performance using multithreading and/or parallel processing and logical partitioning (postgres):

select id, col1, col2, mod(row_number() over (), 4) as partition from some_table;

Thus, a partition index will be assigned to each table row. The idea is to create several instances of my business service using pooling (e.g. Pool Size = 4) so each business service instance will be responsible to hande rows belonging to a certain partition, e.g.

 I have dynamic sql select query ,

Set resultset = ##class(%ResultSet).%New()

 set sql = "SELECT COUNT(*) FROM "_tableName_" WHERE "_fieldName_">='"_fromDate_"' AND "_fieldName_"<='"_currentDate_"'"

 SET SC = resultset.Prepare(sql)

 SET SC = resultset.Execute(sql)

How can I print/view the count ?

With the introduction of vector data types and the Vector Search functionality in IRIS, a whole world of possibilities opens up for the development of applications and an example of these applications is the one that I recently saw published in a public contest by the Ministry of Health from Valencia in which they requested a tool to assist in ICD-10 coding using AI models.

How could we implement an application similar to the one requested? Let's see what we would need:

1. List of ICD-10 codes, which we will use as context for our RAG application to search for diagnoses within the plain texts.

I need to make changes to  OBX 5 which shows as immutable

I have tried ConstructClone, ThrowOnError, and Streams but I can't get the syntax correct

Example

OBX|1|TX|2000.02^REASON FOR REQUEST^AS4|142|REASON FOR REQUEST:      Total Cost:           0.00||||||O
                                        ^^^^ remove "REASON FOR REQUEST"                                                                            ^^ add cr/lf so down stream reports can be formatted more easily

I have the code done to parse out the "REASON FOR REQUEST" but I need to make the OBX 5 show the change.

Before:

OBX|1|TX|2000.

You can use the WriteToConsoleLog method of the %SYS.System class to write any message to the console log.

The following is an example:

%SYS>write ##class(%SYS.System).WriteToConsoleLog("xxxxx log message",0,0)
1

For details on the parameters that can be specified in the WriteToConsoleLog method, please refer to the following document:

Hello interface engineers and app developers,     

Did you know that you can use Python in productions or integrations?

The production configuration user interface is low-code, but in many projects, you may reach a point where you need to write some code. As discussed in the Integration Architecture course, business processes are full of places for inserting code, specifically the BPL editor (for BPL business processes) and the DTL editor (for data transformations).

😯 As of InterSystems IRIS 2025.1, both Python and InterSystems ObjectScript are supported in the BPL and DTL editors.

Greetings,

Is it possible to change the date format from YYYYMMDDHHMMSS to YYYYMMDD in a DTL? How?

I tried ConvertDateTime() without success. 

I'm using Iris for Health

Thank you!

I have a HL7 DTL in which I'm doing a lookup to a table based on a code value in the IN1:3 field.  That incoming code may have a 1 to 1 mapping, or 1 to many mapping in a table.  If it's a 1 to many, the values in the lookup table are comma delimited.  If it's 1 to 1, that IN1 segment will map straight across.  If it's one to many, I need to create additional IN1 segments.  For example, if the incoming code maps to three, I need to map the original IN1 segment with one of the mapped codes, then create two additional IN1 segments with the other 2 codes for a total of 3 IN1 segments.

I was using VSCode to edit a DTL because it seemed easier to copy/paste code from parts of the DTL I was editing. I tried to add <sql> tag and code to call a SELECT statement, but when I compiled I got the following error...

ERROR <Ens>ErrInvalidDTL: Invalid DTL

  > ERROR #5490: Error running generator for method 'GetSourceDocType:osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'

This can be done with TRY-CATCH:

 #dim ex As %Exception.AbstractException
 TRY {
    //Code that causes an error
  }
  CATCH ex {
     do ex.Log()
  }

If you use ^%ETN, call it from the BACK entry (BACK^%ETN).

Once upon a time in Ensemble Management Portal the pool size of each component (Business Host) within the production was displayed in the Production Configuration page.

This information was very useful, especially when a production have tens or hundreds of components.

Now days the pool size is no longer displayed in the Production Configuration page and to get the pool size you need to click in each and every host in your production.
What if you have hundreds of business hosts and you need to check the pool size of each? It's a nightmare!

Hello,

I'm using the .Net C# IRIS client and trying to create a HS.Data.OIDMap object which contains a $LIST property (.IdentityTypes). I am able to create the object using the .NET client, however when trying to create and assign the list object I get a "List cannot contain of type IrisObject".
Documentation for HS.Data.OIDMap https://docs.intersystems.com/irisforhealth20243/csp/documatic/%25CSP.Documatic.cls?LIBRARY=HSSYS&PRIVATE=1&CLASSNAME=HS.Data.OIDMap 

My question is two fold

1. How to do you set a object property that is a list that needs to container other IrisObjects?

The FHIR standard establishes a powerful but flexible data model that can smoothly adapt to the complexities of operational healthcare data management. This flexibility comes at the cost of a data model with many tables and relationships, even for simple data such as the patient's record of telephone numbers, addresses, and emails. It would easily require querying 4 different tables. However, FHIR SQL Builder eliminates this problem, allowing you to create visual projections (mappings) in web wizards.

I have two instances of IRIS, one is Production and another one is Staging (both managed by Docker) and I want to set up a full daily recover of the Staging server from a full backup of the Production server. I know how to do this manually using the DBREST utility, as well as how to make a copy of the database by making a full copy of the durable directory (however this option requires a full stop of the Production-database). What is the best way to automatically restore all databases from a full backup using scripting?

The VS Code extension development team is looking for beta testers to provide feedback on a proposed overhaul of the client-side editing workflow. The full list of changes can be found in the GitHub pull request description. Here are the highlights:

• Support the use of client-side editing in any non-isfs workspace folder, not just folders in your local file system. For example, with VS Code Remote Development.
• Create an index of all Classes, MAC and INT routines, and Include files inside non-isfs workspace folders.

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a  EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation.  Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation? 

Thank you.

I have the need to query an external database and write the result set/snapshot to an internal %Persistent [ DdlAllowed ] table that I built. I have built inbound SQL Services before and write them externally to replace SSIS jobs, but how would querying a database via a Service and writing the data to an internal table work?

Can I just take the inbound query structure and write it to the class file of the internal table in a DTL? If so, what would be the Target? Or does this need to be done within a BPL as a Code block?

Hi experts,
Please, do you know steps to analyse and correct this alarm?
