Users of the InterSystems Change Control Record application (CCR) often ask for useful resources which can help them learn CCR and stay in the loop on updates. Please see this list of resources below and post ideas for additional resources or questions you may have!

We have a custom business service that is triggered by a scheduled task. The service queries a table, iterates over the result set and sends a message on to a business process for each result. Happy path functionality is all fine.

However, when there is an error detected in the business service code, neither throwing an exception nor returning an error %Status behaves as we'd expect.

Hi,

I want to list the source if a class in an 'iris session'.

I know I can get a list of all classes in a namespace:

iris session <session> -U "%SYS"

DO $SYSTEM.OBJ.ShowClasses()

===

Is there a similar sinmple command to get the source of a class?

We have a requirement where in certain data from IRIS in almost real time has to join with SQL tables and we are trying to avoid linked servers.

Is there a way to achieve this without having to go through ODBC?

If anyone has experience debugging Embedded Python or has insight into why an ObjectScript method when called from a Python method would not work but would work when called directly via ObjectScript or in a Python shell, your help would be appreciated!

We have an ObjectScript ClassMethod called GetTemplateString() which takes in a templateName of String type and uses the template name to get the template object, access the Code, and read the code into a templateString. The string version of the Code is returned.

Hi,

I use the data functions but don't know what they all do. Is there a dictionary that explains what each function does?

Thanks,

I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.

In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.

I'm attempting to represent this as such:

I have this code and I need to send

Set tRequest= ##class(Testing.Messages.GatewayCreateFacilityRequest).%New()

I have a few routines in ^rINDEX that are missing in ^ROUTINE. At least some of those routines lack a timestamp, probably Date and Time Modified in ^rINDEX. It causes D %RO crash when such a routine is referenced by a routine range, since "" is an illegal $ZDTH value.

Healthy entry (note the timestamp): ^rINDEX("ABC,"INT") = $lb("2021-06-15 15:08:38.846885",) ;The second argument is sometimes present and sometimes not, likely the routine size.

Unhealthy entry (note an empty timestamp): ^rINDEX("DEF,"INT") = $lb("",21)

I have a table that is already created and contains data. I need to create a unique constraint that is a combination of two fields. Is there a way to do this in a SQL statement? Also, I would lke to know how to add it in the table class.

I have just started working on cache and I am trying to push code from a tfs repo to a cache server namespace. I know that from you vscode you just can compile and that would reach the namespace. But I want this process to be automated , like a ci/cd pipeline that gets triggered only from a kube container. Is there any documentation which I can follow. We are still using cache not IRIS

Introduction

In today's rapidly evolving threat landscape, organizations deploying mission-critical applications must implement robust security architectures that protect sensitive data while maintaining high availability and performance. This is especially crucial for enterprises utilizing advanced database management systems like InterSystems IRIS, which often powers applications handling highly sensitive healthcare, financial, or personal data.

Hi Community,

Let's meet at the online meetup with the winners of the Python Contest. It's a great opportunity to chat with the InterSystems Experts team and our contestants.

I need an example of how to consume a pipe-delimited flat file place parts of it's content into parts of the SDA. I have the RecordMap built, but am unsure of where to go from here.

Any help would be greatly appropriated.

Thanks,

Lawrence
