An interesting pattern around unique indices came up recently (in internal discussion re: isc.rest) and I'd like to highlight it for the community.

As a motivating use case: suppose you have a class representing a tree, where each node also has a name, and we want nodes to be unique by name and parent node. We want each root node to have a unique name too. A natural implementation would be:

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,

TLS v1.2 support in Caché

Question:

What version of Caché supports TLS v1.2? 

Answer:

Caché 2015.2 announced support for TLS v1.1 and v1.2.  In this version, the SSL/TLS configuration page provides checkboxes for TLS v1.1 and v1.2, which allows the versions to be configured individually.  This allows sites to, for example, require TLS v1.2 only.

Additionally, some earlier versions of Caché provide undocumented support for TLS v1.1 and v1.2, specifically Caché 2014.1.3 and above and 2015.1, on Windows, Linux and Unix.

Hello, today we had another freeze in the system. It was close to 09:55. Logs follow for analysis. Following are MSM/MUMPS logs with about 1050 active connections at the time of the freeze. Does anyone see something different?

InterSystems Native SDK for Python is a lightweight interface to InterSystems IRIS APIs that were once available only through ObjectScript.

I'm especially interested in the ability to call ObjectScript methods, class methods, to be precise. It works, and it works great, but by default, calls only support scalar arguments: strings, booleans, integers, and floats.

But if you want to:
- Pass or return structures, such as dicts or lists
- Pass or return streams

You'll need to write some glue code or take this project (installs with pip install edpy). edpy package gives you one simple signature:

call(iris, class_name, method_name, args)

which allows you to call any ObjectScript method and get results back.

Hi developer folks!

Thanks to all of you who start the development with InterSystems IRIS from the basic development template!

Recently, thanks to @Dmitry Maslennikov's contributions I've updated the Dockerfile to make the development simpler, images lighter and the building process faster. And it looks more beautiful too ;)

Here is what changed:

Hello,

We have a scenario where a bad message(With control character in some fields) is coming frequently in our Standard HL7 Business Service.

I do see the process gets shut down because of E=D action code. I also see the service logging an "Warning" about the bad message. But service is not shutting down.

Is there a way to handle this error right at the service to avoid multiple processes going down? Not sure if we can create a task, which audits the service logs every few minutes. But that will involve some coding and checking of time when the errors happens.

Hi Guys,

I'm using the below to export a query result to excel file and the only file type is .csv (100) but the resulting has two problems,

first the row header is including the field type and second the resulting file is a tab delimited so columns aren't properly separated (see attached below) 

set st = ##class(%SQL.Statement).%New(2,"Sample")
set sql = "select ID, name from MyClass"
do st.%Prepare(.sql)
set type="csv"
  set rs = st.%Execute()
  do rs.%DisplayFormatted(type,"C:\Temp\report")

Hi there have been various posts around how to clean up globals without parent data but none have gone into how you solve these issues. 

Our database is approaching 600gb in size so i am looking into how to reduce this. 

We use standard purge tasks. 

Our cache stream class has a global size of 2463243 from running global size so it is what i would like to tackle first. 

1) is there any way i can find based on my oldest message session for where most of these globals

Is it a good practice to set the MAXLEN value of %Library.String property type?  Will it lead to wasted storage if its not really using it?

For example, I have to store a 5 characters long string into the below str field. Which of the statement is recommended? 

Property str As %String;

vs

Property str As %String(MAXLEN="5");

Hello guys!

The Global Summit 2022 in Seattle ended just over a week ago but keynotes are already available for those who missed them while being on the premises or who couldn't attend this in-person event at all for some reason or another (or just for those who wish to refresh their memory and listen to them again).

Without further ado, the beginning of the Global Summit AKA the Greetings from the Community:

I just met a personal challenge translating my article to French.
Tough I had to learn it at school and could read and understand
famous literature (Sartre, Molière, Mauriac, Proust, Saint-Exupéry, Anouilh, ...) 
I missed the specific terms used with ISC technology.
Thanks to @Lorenzo Scalese my errors were corrected.
But no dictionary was able to answer.
