#InterSystems IRIS

I'm working in an application that uses %SIMILARITY to find matches among a set of documents that vary greatly in length. It's generally good but I've noticed issues with ranking short partially-matching documents over longer documents that match the search string entirely.

Reading up on the Okapi BM25 ranking function (which is what %SIMILARITY / the %Text package use) at https://en.wikipedia.

I have a BPL Business process which always processes messages - mainly it waits for responses since downstream systems are seriously async.

I need to update this process.

Wwould the existing instances of this Business Process complete correctly after the update?

My BPL changes would result in:

1. New S method in the Thread class
2. New OnResponse method in the context class

Both changes are in the middle of the process, so there are S/OnResponse methods before and after my change.

What if it's only a new S method? What if it's only a new OnResponse method?

I'm building a Flutter app for smartphones and with same code a Flutter web app.

Both are using IRIS with a RestAPI.

As described in your documentation

• https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=G…;

I added

in the Info block of the Swagger definition and added

• Parameter HandleCorsRequest = 1;

in the spec file after generating the RestAPI.

I also copied the example dispatch class to

Hi all,

Are there limitations to the size of a file or stream that %XML.Reader will parse?

I am trying to parse a large, 573MB, XML file using either the 'OpenFile' or 'OpenStream' methods, but both return errors.

When I try to use the 'OpenStream' method I get a 'ERROR #6301: SAX XML Parser Error: input ended before all started tags were ended' error',

and when I try the 'OpenFile' method I get a 'ERROR #6301: SAX XML Parser Error: <STORE>'.

'%XML.TextReader' appears to parse the file OK, so I may be able to get use that as a workaround, but ideally I would like to get '%XML.Reader' working.

Hey Community,

We want to hear from you! Give us your feedback on the past InterSystems AI programming contest! Please answer some questions to help us improve our contests.

👉 Quick survey: InterSystems AI Programming Contest Survey

I am trying to find the best way to evaluate if OBX-3 = ^IS TEST PATIENT? and OBX-5 =  Y In the same OBX in a Business Rule

OBX|1|NM|P-CSN|1|7623201922192||||||F
OBX|2|NM|P-UCI|2|||||||F
OBX|3|TX|^ADT: PATIENT CLASS|1|Outpatient|||||||||20210715
OBX|4|TX|^IS TEST PATIENT?|1|Y

I started to create a function in a class that uses the Rule [] bracket syntax and  extends  Ens.Rule.FunctionSet:

But after some initial troubleshooting I realized that the [] brackets will not return a value if a field is null, making the two lists different lengths and impossible to compare.

HL7.

Hey Developers,

The InterSystems AI programming contest is over. And now it's time to announce the winners! 

Are you excited?

A storm of applause goes to these developers and their applications:

Hi,

When for any particular reason I need to update a record and don't want to pull the triggers, the keyword %NOTRIGGER can be used. But I've been trying to do the same when I change the row using the object approach, but I can't find it. Anyone knows if it's possible to avoid pulling triggers when working with objects?

Sadly, the utility "DISABLE^%NOTRIGGER" doesn't seem to exist ;-)

Thank you,
David

Hi Developers!

We had a set of technology bonuses for the InterSystems AI/ML contest.

And here is how projects collected it:

Hi.

I'm trying to serialize/deserialize an .PNG picture. After serialization in C# (using System.Text.Json.JsonSerializer) and sending it to IRIS it is deserialized with %JSONImport method and saved to %FileBinaryStream. File is created on server and can be normaly opened with Paint. But when I want to recall it in C# (serialization with %JSONExportToString and deserialization with System.Text.Json.JsonSerializer), I get an error "FormatException: Cannot decode JSON text that is not encoded as valid Base64 to bytes".

Hey Developers,

This week is a voting week for the InterSystems AI programming contest! So, it's time to give your vote to the best solutions built with InterSystems IRIS.

🔥 You decide: VOTING IS HERE 🔥

How to vote? Details below.

when trying iris, the provision sandbox isn't working. what's wrong or what should i do? thanks so much.

I'm pleased to announce a major release of the InterSystems Server Manager extension. It has gained a UI!

Read more at Open Exchange.

Right now version 2.0 is like an aircraft at the start of the runway (remember those days before COVID-19?), waiting for the control tower to give final clearance. Will you be an early adopter, downloading the VSIX from GitHub, installing it into your VS Code, and posting back here to confirm that we haven't left anything critical behind at the gate? Then I'll push the throttles forward, publish to Marketplace, and we'll all be on our way.

Server Manager 2.0 is my entry for the current contest. If you like it maybe you'll vote for me it.

cAdvisor (short for container Advisor) analyzes and exposes resource usage and performance data from running containers. cAdvisor exposes Prometheus metrics out of the box. 

https://prometheus.io/docs/guides/cadvisor/

Prometheus is integrated in SAM. This makes it possible to leverage the cAdvisor metrics and expose them via Prometheus and Grafana.

Since cAdvisor listens on port 8080, which conflicts with the Nginx port, you can choose to change the Nginx port to accommodate that.

Configuration Steps:

1. Change nginx port.

modify nghix.

Hi folks!

How do you edit data in IRIS or Caché? What do you use?

Change globals directly via Management Portal?

Change data using SQL?

Use your favorite dev tool? Which one?

Crafted your own?

Share your experience, please?

Greetings

Reaching out the development community to understand if there is anybody out there whom have developed a financial transactional switch or stock exchange on Intersystems before.  If so please DM me on +27 66 243 1618.

Many thanks and Regards

Fixing the terminology

A robot is not expected to be either huge or humanoid, or even material (in disagreement with Wikipedia, although the latter softens the initial definition in one paragraph and admits virtual form of a robot). A robot is an automate, from an algorithmic viewpoint, an automate for autonomous (algorithmic) execution of concrete tasks. A light detector that triggers street lights at night is a robot. An email software separating e-mails into “external” and “internal” is also a robot. Artificial intelligence (in an applied and narrow sense, Wikipedia interpreting it differently again) is algorithms for extracting dependencies from data. It will not execute any tasks on its own, for that one would need to implement it as concrete analytic processes (input data, plus models, plus output data, plus process control). The analytic process acting as an “artificial intelligence carrier” can be launched by a human or by a robot. It can be stopped by either of the two as well. And managed by any of them too.

July 21, 2021 – Alert: Incorrect Query Results with Non-Standard ‘GROUP BY’ Query

InterSystems has corrected a defect that can cause incorrect query results. This defect affects:

• All major releases and maintenance versions of InterSystems IRIS and InterSystems IRIS for Health, starting with 2019.1.0

A query block may encounter the defect only if it meets all the following conditions:

• The query block contains a GROUP BY clause but does not include any aggregates, such as COUNT(*).

I want to achieve the same function as the management portal under the Utilities menu。

I wrote a studio.sourcecontrol menu tool. I want to use chrome to open the CSP page. Now I can open it to CSP, but the IP address is the intranet IP of the cloud server. How can I get the IP of the current studio connection?

Set CompName = $p(InternalName,".CLS")
//Do ##class(%Studio.General).GetWebServerPort(.IP,.Server,.urlprefix,.ipport)
Set url= ##class(csp.csp.download).%GetParameter("CSPURL")
Set IP = $p($zu(54,13,$zu(54,0)),",")    // Intranet IP  。

Apologies if this isn't the correct forum but here goes..

I'm accessing an Intersystems database from MS SQL Server using Intersystems ODBC driver and using OPENQUERY statement to read metadata of tables using

SELECT * FROM OPENQUERY([<linked server name>], 'SELECT * FROM INFORMATION_SCHEMA.COLUMNS')

but I get an error message saying INFORMATION_SCHEMA.COLUMNS cannot be found.

Intersystems SQL documentation does reference this table so is there some other way to access this table or is it maybe a permissions issue?

When I'm asked questions about SQL, I like Intersystems staff at the WRC, generally ask about the Query Plan.  My feeling is that even before you run a query you should examine the results of Show Plan to confirm that the code is going to give me the results in the manner I would expect.  If I expect it to leverage an index and I see that it is not then I go back and look at what I might have done incorrectly and try to re-write the query to get the index behavior I'm looking for.

Writing a script for the application deployment can be very interesting to ensure rapid deployment without forgetting anything. config-api is a library to help developers to write configuration scripts based on a JSON document.

Implemented features :

• Set system settings.
• Set security settings.
• Enable services.
• Configure namespaces, databases, mapping.
• Export existing configuration.
• All features are exposed with a RESTful API.

This library is focused on IRIS configuration to help applications deployment.

 Native API  , IRIS 2019 regression vs Cache .Net provider 

1. checking the native API, with .net provider, from IS docs, I realize,

that it is not possible to wrap objectSricpt Class with .NET (C# for example) pure Class with it's methods/properties

and make pure instance syntax of: new myNetClass - as wrapper of irisClass.

as I realize, you can run  .Net Class , only with .Invoke or iris.ClassMethodVoid("class.name","method")

such syntax, cannot execute event driven on proprety change, let say, with it's build in mechanizm in .Net

2. IRIS 2019.

this version is missing the class IRISObject  ?

Hi All,

I have a requirement where I have to create a TIF file from base64 encoded string comes in HL7 message.

I am reading content and writing to  %Stream.FileBinary after decoding and using  ..Adapter.PutStream ( EnsLib.File.OutboundAdapter) to create a file at operation. the file is getting created but its corrupted.

IS this even possible in cache? what is the correct way of doing this?
