and a Business Operation calling the SP

The following code executes the stored procedure successfully , but does not return the output.

what needs to be fixed?

I wonder why IRIS seems to have its on way to deal with order or operations such as the example in the title. This affects regular arithmetic operations but of course conditions in various statements.

Even after years of COS development, I still get caught by these tiny frustrating details and it is absolutely annoying when you are writing APIs that some some maths.


Here is an example:

For some years I missed being able to offer, to everybody interested in ObjectScript, a tutorial more or less complete, to start with ObjectScript. Something that could help more and make things easier to those new developers that come to our technology... something intermediate, halfway between the common "Hello World!", that doesn't really get you further, and the "Advanced Training", that is unaffordable because of lack of time,etc.

If there were something truly helpful not only as an introduction to the ecosystem, but as a starting point, as a boost, to really start to walk into ObjectScript and move forward by yourself... wouldn't that be awesome?

Hi all

I'm new to ObjectScript and I've been experimenting the correlate method of %XML.Reader to convert an XML file I've loaded into its corresponding class. But, I have found that I am not getting all the child items of an element in a List contained within the converted class, only the last item.

The XML file content is as follows:

Mutual TLS setup


I recently needed to setup an SSL/TLS configuration in IRIS that supported mutual authentication (where the server IRIS is establish a connection to is verified, and, where IRIS is in turn verified by the remote host).  After a bit of research and getting it done, I thought it worthwhile to just go over the process I went through in order to potential help others, and save you some time .

Pouring The Coffee: Creating and scheduling a task

Don't you wish a fresh, hot cup of coffee could be waiting for you right when you get into the office? Let's automate that!

Cache and IRIS come with a built-in Task Manager, which should have a familiar feel to those used to using the Windows task scheduler or using cron on Linux. Your user account will need access to the %Admin_Task resource to use it, and you can access it in the management portal under System Operation -> Task Manager. When first installed, there are roughly 20 types of task that you can schedule.

Apache Zeppelin it's a Multi-purpose notebook that allow you:

  •     Data Ingestion
  •     Data Discovery
  •     Data Analytics
  •     Data Visualization and Collaboration.

Apache Zeppelin interpreter concept allows any language/data-processing-backend to be plugged into Zeppelin. Currently Apache Zeppelin supports many interpreters such as Apache Spark, Apache Flink, Python, R, JDBC, Markdown and Shell.

Running HealthConnect 2021.1 on RedHat Linux 8.4.

I've configured IRIS/HealthConnect with an external web server to support TLS encryption. It's installed on the same server as IRIS, but is a different instance and version of Apache httpd. That all works as expected.

I would also like to keep the "private" web server available, but I'm having an issue with using the fully-qualified domain name in the URL vs. just the hostname itself.

If I use http://servername:52773/csp/sys/UtilHome.csp to log on, all is well.

In a Business Operation i have the following code.

I need the identity of the latest row inserted in a table in MSSQL.

i Have the following code:


set insertmaster= "INSERT INTO dbo.dataMasterArchive(deviceToPatientLogID) values (?)"

set tSC = ..Adapter.ExecuteUpdate(.nrows1,insertmaster,pRequest.deviceToPatientLogID)

Hi All,

I'm having a strange issue where doing a .setValue on a ZEN datacombo is updating it with the value as-is, not the corresponding display value. Eg, if I connected it to query that returns two columns: ID,Name, and do a setValue(ID), I would expect the text in the datacombo to update showing Name. Instead it updates show ID, which I only want to use internally.

Working in support, I usually get asked how many days I should keep journals. Should it be two days or after two backups? More? Less? Why two?

The correct answer (for most of the environments) is that you should keep the journals since the last validated Backup. I.e., until you don't check if a Backup is valid (restoring the file and checking with the Integrity utility), you can't be sure there is a good copy of your data and can't purge the journals safely.

Hello there!
I am hoping to get some help with "SQL Search index" and JSON objects.
I am storing a JSON object in a column of type %Stream.GlobalCharacter 
Property JSON As %Stream.GlobalCharacter;
I also have a index that looks like below.
Index AnalyticIdx On (JSON) As %iFind.Index.Analytic(INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);
