#InterSystems IRIS

I have just created a new Global Master Topic, "IRIS Cheatsheets". IRIS has introduced a lot of new functionality, especially in scripting languages, FHIR R4 support, enhanced Interoperability Tools, and IRIS Analytics. Having spent 35 years working on Windows-based PC's and Laptops, I have surprisingly little knowledge of Linux, Docker and Git. Furthermore, I have written almost every application and Interface in ObjectScript with splatterings of SQL, .Net, and Java Gateways and the most basic knowledge of WinSCP, Putty, SSH. All that changed when I received my first Raspberry Pi.

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.

However, if I click on the dropdown, showing all the valid Names, select one, it works fine, showing Name (with the ID retrievable by getValue() as normal).

In my previous articles I demonstrated the steps to connect, retrieve and save data to Caché from Appeon PowerBuilder by using ODBC.
In this article I will demonstrated how to Delete data from Caché with Appeon PowerBuilder (https://www.appeon.com/products/powerbuilder) by using ODBC 

I am using Company.cls from Samples-Data (https://github.com/intersystems/Samples-Data/tree/master/cls/Sample) 

So Let's start:

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.

For example, imagine you need to restore your system after a hardware failure that corrupted some databases.

Hi Community,

We are pleased to invite all the developers to the upcoming InterSystems Security Contest Kick-off Webinar! The topic of this webinar is dedicated to the Security contest.

We’ll discuss the aspects of Security Model implementation in InterSystems IRIS, the requirements, and what do we expect from participants of the Security contest. Also, we’ll answer all the questions related to the contest!

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code. 

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace. 

By ensuring your code is maintainable, you can reduce approximately 75% of the systems life cycle costs*. This is why, at George James Software, the solutions we build are always straightforward and written in high quality code - because we know that this solid foundation can positively impact the rest of your organization. 

With a maintainable system you're able to reduce your overall maintenance as any issues that occur are significantly faster to identify and fix. This means you're free to allocate that time and budget to enhancements, enabling you to get the most value out of your applications and ultimately better support your organization. 

Keep an eye out for our next few posts about what a maintainable system looks like and the tools that can help you keep your code maintainable, in order to help you to reduce those maintenance costs.  

Hi Guys

I'm rather new to HealthConnect, and I've been doing a lot of work with the browser based SQL portal and don't particularly like it. Is there an alternative application that I can use, something like SQL Express or VScode with a plugin?

Andy

I'm trying to send a POST request to my REST API and I'm getting this error and most likely due the lack of experience, I have no idea how to fix this issue:  

"error": "ERROR #9406: Unexpected format for value of field, AlertText, using class base mapping",

            "id": "JSONImportError",

            "params": [

                "AlertText",

                "class base"

            ]

Am I missing something from my string definition?

Defined below as:

Class User.RESTComponents Extends (%Persistent, %JSON.

Hey Community, 

The new video is worth watching on InterSystems Developers YouTube:

⏯ Data Warehousing with InterSystems 

The TOGAF is the The Open Group Architecture Framework. It provides an approach for planning, design, implement, deploy and govern your EA (Enterprise Architecture) projects.

The TOGAF has a concept called Building Block. It is any element that can be used, reused a executed to deliver value and new functions to the business.

In the picture above, I present to you the main IRIS building blocks to create fantastic apps.

To learn more about TOGAF and building blocks, see https://www.opengroup.org/togaf.

I'm in a tricky situation where a new required property is being added to a class, along with an index on it. The existing data has nulls, so the index build fails. I can't run a query to update the rows where there are nulls, because it tries to use the index, which hasn't been built yet.

I realize that a valid workaround would be to remove the index, add the property, run the query to do the update, then re-add the index, but this feels overly messy (and doesn't fit well with my logic for incremental deployment).

Hi folks!

Could you please share your experience on how do you create REST API with InterSystems IRIS that uses bearer authentication?

How do you generate tokens? How do you maintain it (how much time tokens exist?).

Thanks in advance!

Ladies and gentlemen!

Is there a way (some secret call? ) to turn on a debug mode for a particular IRIS web app?

The reason is to log debug information in REST-API dispatch methods if the app is in debug mode.

Of course, I could use "a global", but if there is any standard way?

Hello,

We are connecting to our client's Intersys database with python3.8 on our Ubuntu 20.04.2 LTS, we are having trouble gettin the intersys.pythonbind module to work.

We are able to install the intersystems_irispython-3.2.0-py3-none-any.whl but, when we try to run the code we always get:

Traceback (most recent call last):

  File "./get_well_life.py", line 4, in <module>

    import intersys.pythonbind

ModuleNotFoundError: No module named 'intersys'

Please could you tell us what may be going wrong?

Please also feel free to ask for any additional infomation.

Thanks and regards!

⏯ Introducing the InterSystems IRIS Smart Factory Starter Pack for Manufacturing

Hi Community,

We're pleased to invite you to the upcoming webinar in Spanish called "Self-Service Analytics & Reporting"!

Date & Time: November 17, 4:00 PM (CET)

Speaker: @Alberto Fuentes, Sales Engineer, InterSystems Iberia

The webinar is aimed at Data Analytics or Business Intelligence professionals.

I want to write some code differently to run on Primary, Backup and DR depending upon their status.

If its Primary then do something, if Backup then something else and if DR then do something different from both Primary and Backup.

This can identified whether a system is Primary or Not Primary by calling below method

w $SYSTEM.Mirror.IsPrimary()

1 means Primary and 0 means Not Primary. But a Not Primary member may be a backup or a Async DR or a Async Reporting.

How to identify if a system is a DR or Backup or Reporting?

I was looking at the thread of messages on the topic of "Performance when constructing a comma-separated string", and I started writing a response but got distracted, the page refreshed, and I lost my text. I couldn't spend the time rewriting my response, so I started writing this document instead.

I started writing MUMPS at the beginning of my career. I wrote very tight and dense code blocks where exercises such as the string example were authentic challenges.

One of our apps uses a class query to support a ZEN Report and works just fine in that report, producing the expected results every time. We’ve since migrated to InterSystems Reports and noticed that, for a report using the same class query, 100s of extra rows with the same column values appear at its bottom.

We eliminated InterSystems Reports as the source of the problem by recreating the same “extra rows” issue with an Excel spreadsheet calling the same class query as a stored procedure.

What was the issue?

I want to INSERT a record in a database using JDBC in  OBJECTSCRIPT. At the same time, I want to obtain the insert ID. Is there a way to achieve this using the SQL Outbound adapter?

My code is something like this now:

Property Adapter As EnsLib.SQL.OutboundAdapter;

set sql = " INSERT INTO Prenotazioni_CUP "_
                  " (ID, cf
                  " VALUES (SEQTAB.NextVal, ?) "
set status = ..Adapter.ExecuteUpdate(.rs, sql, pRequest.cfAssistito)

Hi guys,

My client has a requirement to add a column of random numbers to the query result.

I wrote a function as below:

Class Utils.SqlUtility Extends %RegisteredObject
{

ClassMethod GetSomeNumber(intInput As %Integer) As %Integer [ SqlName = GetNumber, SqlProc ]
{
    Return $R(intInput)
}

}

But in the returned sql result, every row share the same value, as below,

SELECT Utils.GetNumber('456'),
ID, Citizenship, DOB, FirstName, Gender, IDNumber, LastName, PatientNumber, PhoneNumber
FROM CDR.Patient

How may I refactor the function or sql to make the random value really random on each of the rows?

Thanks.

Hi community!

I want to introduce you a new powerful feature from our static code analyzer objectscriptQuality. 

Each time a new IRIS version is released, you need to prepare a roadmap for migration in which you need to spend a lot of time on testing to find where your code is not accomplishing with the newer version. Or maybe you need your code to be compatible with multiple IRIS or Caché versions.

You can now simplify the task running the analysis for the different IRIS and Caché database versions, so you will get the failing code before you start to test.

Hi

We have ODBC 32bit Encryption working on our database with a SSLDEFs.ini file.  However 64 bit ODBC Encryption will not work and give generic error, same error if the ini file is not there for 32BIT.

We have copied the ini file to the 64bit folder?  Any ideas please?

thanks
