Developer Preview releases are now available for the 2022.2 version of InterSystems IRIS, IRIS for Health, and HealthShare Health Connect.

This is the second in a series of releases that are part of the developer preview program for 2022.2 Future preview releases are expected to be updated biweekly and we will add features as they are ready. This program allows us to get feedback on capabilities and enhancements as they're available. You'll see below a list of enhancements that are targeted for 2022.2. Some these are not included in this developer preview.

Hi,

I'm trying to load some data into IRIS using LOAD DATA in the IRIS terminal however I am getting blocked by this error. I have read the documentation on this page trying to set up a gateway connection but get the same Connection cannot be established error.

This is what is in the %Java Server activity log

ID 	Date Time 	Record Type 	Job 	Text 
8132022-07-1810:37:09	Info	28048Job command successful, started monitor process '6404'
8112022-07-1810:37:09	Info	28048	Starting background process to monitor the Gateway Server
8102022-07-1810:37:09	Info	28048	Gateway Server start-up

Is there a way to perform an %Prepare()/%Execute() that will wait until the record being queried is unlocked by another process? 

Ex: 

Process 1 - is opening record, updating, then saving. NOTE: this is using embedded SQL

&sql(SELECT %ID INTO :id FROMtable WHERE Prop=:prop)
s obj=##class(APPTRACKER.CacheHB.CustomEventCacheHB).%OpenId(eventId)
//updating record...s sc=obj.%Save()

Process 2 - is querying the same record while Process 1 has it open. Result is nothing is returned and %SQLCODE is 0

//simplified snippet with extra code removed
    ...
    s sql = ##class(%SQL.Statement).%New()

Hi,

I want to access a Stored Procedure in a remote SQL Server Database. I am quite new to Object script.

The stored procedure has 3 parameters: 2 datetime parameters and 1 integer.

Which is the best way to do that? I'm wondering if I can use the link stored procedure feature inside object script or some SQL statement in Object Script.

This SP returns a set of rows which I want to read, transform and save in a persistent class.

Thanks in advance,

Hi Community,

Just thought I'd let you know that you can still get a LifeStraw water bottle for completing a Gartner Peer Insights survey. With a built-in filter that removes bacteria, parasites, and microplastics, this water bottle is especially useful for hikers. Plus Gartner will give you three months access to its Peer Insights Plus, "an exclusive service that aims to help tech professionals stay current on technology trends and excel in evaluating software/services."

The Gartner reward is automatic.

I want to display to the user on their Zen page how much time is left before their session times out.

I know I can set the %session.AppTimeout to a particular value (or manage this in the Web Application) and I know I can retrieve this value from the %session object. I also know that I can set an event handler to do something when the session has timed out but I cannot find any way to determine how long before the session ends via the application timeout so that I can keep the user informed.

I'm aware the session timeout triggers based on the inactivity of the user but I can't find anything

Hey Community,

Hi! My name is Sergei Sarkisian and I’m creating Angular frontend for more than 7 years working in InterSystems. As the Angular is very popular framework, our developers, customers and partners often choose it as part of the stack for their applications.

I would like to start series of articles which will cover different aspects of Angular: concepts, how-to, best practices, advanced topics and more. This series will target people who already familiar with Angular and wouldn’t cover basic concepts. As I’m in the process of building articles roadmap, I would like to begin with highlighting some important features in most recent Angular release.

Hi! Today I would like to talk about one of the most important architectural patterns in Angular.

The pattern itself is not related to Angular directly, but as Angular is component-driven framework, this pattern is one of the most essential for building modern Angular applications.

Container-Presentation pattern

It is believed that good components should be small, focused, independent, testable and most important - reusable.

If your component is making server calls, contains business logic, tightly coupled to other components, knows too much about other component’s or services’ internals, then it

I did a google search for 'Grafana' and 'IRIS Health'.

This gave these candidates:

https://github.com/caretdev/grafana-intersystems-datasource
https://community.intersystems.com/post/using-grafana-directly-iris
https://grafana.com/grafana/dashboards/14869

Does anyone know which one is 'best'?
If you have used any of these, do you have any detailed instructions on how to install?
Most of these packages assume you know how to install and run them and so are very light on how to install.

I'm using Grafana on a Windows platform (without the use of docker)

Jupyter Notebook is an interactive environment consisting of cells that allow executing code in a great number of different markup and programming languages.

To do this Jupyter has to connect to an appropriate kernel. There was no ObjectScript Kernel, that is why I decided to create one.

You can try it out here.

Here's a sneak peek of the results:

Jupyter Kernels 101

There are several ways to create a Jupyter Kernel. I decided to make a Python wrapper kernel.

We have to create a subclass of ipykernel.kernelbase.Kernel and implement the do_execute method which receives a code to be executed in a

There are many ways to generate excel files using Intersystems, some of them are ZEN reports, IRIS reports ( Logi reports or formally known as JReports), or we can use third party Java libraries, the possibilities are almost endless.

But, what if you want to create a simple spreadsheet with only Caché ObjectScript? (no third party applications)

In my case i need to generate reports that contains large raw data (the financial guys love them), but my ZEN/IRIS fails, gives me, what i would like to call  a "zero byte file", basically says java ran out of memory, and causes heavy load on the

The Carbon Footprint Counter application uses the GHG Protocol to measure carbon emissions on enterprises. The GHG protocol establishes comprehensive global standardized frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Building on a 20-year partnership between World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), GHG Protocol works with governments, industry associations, NGOs, businesses and other organizations. (source: https://ghgprotocol.org/about-us).

This might be a dumb question but I didn't see anything about it in the Mirroring documentation. Are processes that are currently running when the primary fails over to the secondary automatically switched over and continue processing? Or are they terminated and would need to be restarted on the secondary?

I get this on preparing a sql query

ERROR #5580: SQL Privilege Violation: 'User UnknownUser is not privileged for the operation'

There was some embedded sql queries before that which worked fine however.

DISK I / O RATE
SLICE COMMANDS

NUMBER OF MUSERVER PROCESSES We have a rolling MSM that suffers from hangovers from the Activate service and the Workstation service several times a day and we are unable to determine if those hangouts are related to the number of users or overloading the system.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software

I have followed the Article: Continuous Delivery of your InterSystems solution using GitLab, On our own Linux environment it works well but when I try to run it on a clients windows server; and the following command is run by the runner

irissession IRISHEALTH -U TEST "##class(isc.git.GitLab).load()" 

we get the following "error"

<NOTOPEN>>

I do not know why this happens, it does look like it has something to do with user rights but I am totally lost at this point as we have done everything I can think off relating to grant correct access etc.

Does anyone perhaps have something they can point me to

Let's say I have two lists of connected data where elements of listTwo only make sense if given an item of listOne as context:

listOne = ["A", "B", "C"]

listTwo = ["x", "y", "z"]

Tuples like ("A", "y") and ("C, "x") make sense, but "A" or "x" by themselves don't. I would like to pass in a list of such tuples into a method and have it handle each tuple in the list. So what would be the best way to format them given that ObjectScript does not have specialized tuples? Would it be nested $LISTBUILD lists or something else?

What's a good way to add a custom hyperlink to a table item in Clinical Viewer (CV2)? I am customizing the Diagnostic Studies page, and have a custom transform that returns the HTML code for the hyperlink. The hyperlink is supposed to open a custom CSP page in a new window or tab.

Using the layout editor, I then tried adding several "items" to the table like an Icon or External Viewer Link, and use the custom transform to get the hyperlink, but these items only show up as plain text and do not link to any page. How do I turn these items into a hyperlink?

Hi Guys,

is there a way to get an audit or a record of deleted records in a class?

so basically, I'm looking for way to track delete record or from which class or class method call that delete statement was executed,  my understanding is that so for example using %OnfterDelete  I can track any deleted record using %Delete(), so if the user execute a (Delete from myclass)   sql statement can OnfterDelete track that ?

the reason why, is that we have a class where records keeps disappearing (delete) from it and we don't know where or how is this happening, in our software we have 5 places where we

As you can see above, I’ve enabled the namespace for interoperability productions.

I’ve run this creation process with not copying the mappings, copying everything from user, and so on, with out a difference to the end result.

Hey Community!

If you follow our updates, you should know that several months ago we created a new regional community for all those people who speak (and write) French!

You can find it here: fr.community.intersystems.com

After only three months we already have 25 members (I know, it doesn't sound a lot compared to 11.000 members on English Community, but French Community is a newborn compared to an adult) and more than 140 articles, 3.000 views, and 160 likes. We already have exclusive content not present on other regional Communities and our own "thing" which you may spot in our recaps of different events where moderators and admins from the French Community were present.
