InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Hi developers!

Just want to share an old but always relevant best practice on namespaces changing @Dmitry Maslennikov shared with me (again).

Consider method:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

set ns=$namespace

zn "%SYS"

// try-catch in case there will be an error

try {

// do something, e.g. config change

}

catch {}

 zn ns    ; returning back to the namespace we came in the routine

return sc

}

And with new $namespace the method could be rewritten as:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

new $namespace

set $namespace="%SYS"

// do something

return sc

}

So! The difference is that we don't need to change the namespace manually as it will be back automatically once we return the method.

and we don't need try-catch (at least for this purpose) too.

[Background]

InterSystems IRIS family has a nice utility ^SystemPerformance (as known as ^pButtons in Caché and Ensemble) which outputs the database performance information into a readable HTML file. When you run ^SystemPerformance on IRIS for Windows, a HTML file is created where both our own performance log mgstat and Windows performance log are included.

InterSystems FAQ rubric

If the journal file is too large to be searched or filtered using the Management Portal, you can refer to it using the following two methods.

① How to use the ^JRNDUMP utility
② How to reference it in a program

This article will describe processes for running unit tests via the InterSystems Package Manager (aka IPM - see https://openexchange.intersystems.com/package/InterSystems-Package-Manager-1), including test coverage measurement (via https://openexchange.intersystems.com/package/Test-Coverage-Tool).

Hi,

I am using embeded python to utilize some pythonic library but i got a problem on my hand.

One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

If you have system tables implementing the "VERSIONPROPERTY" functionality, you may encounter error 5800. This article explains how this error occurs and provides solutions to resolve the issue.

When version checking is implemented, the property specified by VERSIONPROPERTY is automatically incremented each time an instance of the class is updated (either by objects or SQL).

For example:

Good afternoon!

Is this a good place to find a fellow developer with specialization in IRIS? I have an opportunity and looking for someone with significant experience (10 years).

It's a two and a half year contract, fully remote. Please let me know if you are interested in speaking about the opportunity.

Hi Developers!

With InterSystems IRIS Cloud SQL recently becoming Generally Available, some of you may have had a chance to try it out. Or maybe you used it for your contest entry or during the EAP period. We're curious to learn what YOU think of it. So, have you already tried the new service InterSystems IRIS Cloud SQL?

We have launched a new Ideas Portal category dedicated to this database-as-a-service (DBaaS) where we're looking for your ideas on how we can improve InterSystems IRIS Cloud SQL.

Or share your experience with the service in the comments to this post.

Hello,

I have my server setup a resource server. When a user calls our API they submit a bearer token as authorization and in our dispatch class AccessCheck() we validate the JWT using ##class(%SYS.OAuth2.Validation).ValidateJWT().

If I include a scope to check in that method I get the error Scope check may only be done on requesting client and I'm not sure what this means. The method works without include the scope and will let me know if I have an unsigned token or an expired token.

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

Introducing mg_web

Hot on the heels of our announcement last week about our ultra-high-performance mg-dbx-napi JavaScript interface for IRIS, we are now pleased to announce a significant new technology - mg_web - which not only represents a new paradigm for JavaScript Web Frameworks, but also delivers significantly higher performance than even the fastest of the established Node.js Web Frameworks, whilst leveraging all the benefits of the big-three industry-standard Web Servers.

EnsLib.File.PassthroughOperation has File Name property with default value: %f_%Q%!+(_a)

The Management Portal documentation description of the property:

Name of file to output the document(s) to. May include timestamp specifiers. The %f specifier if present will be replaced with the name of the document's original source filename (stripped of characters illegal in target filenames).

See the method Ens.Util.File.CreateTimestamp() for documentation of timestamping options.

We have JSON type data in a Dynamic Object. Is there a simple way to export / dump that data to a delimited string or file?

e.g.

Results={"ClassA":{"ClassName":"ClassA","ACount":367191880,"BCount":367191880,"CurrentDiff":0,"PreviousDiff":0,"ReportDate":"2024-03-02 00:00:00"}
"ClassB":{"ClassName":"ClassB","ACount":5352149227,"BCount":5352149227,"CurrentDiff":0,"PreviousDiff":0,"ReportDate":"2024-03-02 00:00:00"}}

In recent versions of IRIS, a powerful new data loading command has been introduced to SQL: LOAD DATA. This feature has been highly optimized to import data into IRIS extremely fast, allowing hundreds of gigabytes of data to be inserted in seconds instead of hours or days.

This is a very exciting improvement. However, a big problem in the data loading experience still exists. Namely, the time and hassle it takes to:

I recently had the need to monitor from HealthConnect the records present in a NoSQL database in the Cloud, more specifically Cloud Firestore, deployed in Firebase. With a quick glance I could see how easy it would be to create an ad-hoc Adapter to make the connection taking advantage of the capabilities of Embedded Python, so I got to work.
