Hello,

I'm using a ComplexBatchFileService to retrieve and process a 425 Mo File ( lines ) 

At some point the Business Service is in failure , and displays this error : 

ERREUR #5002: Erreur Cache: <FILEFULL>%SaveData+18 ^CFAO.EOS.MasterFilePR.PMP.RM.ART1.Record.1 ^CFAO.EOS.MasterFileE50F.RecordD(535405931),e:\eos\
+
ERREUR #5002: Erreur Cache: <ROLLFAIL>%TRollBack+10 ^%occTransaction

Do you have any idea about the cause of this error ? ( i have checked the iris databases disk space and it's not full )

Thank you in advance.

Hello all,

I was looking at some code of a business service of which the author is unknown. It's very simple in what it does; it extends from Ens.BusinessService and has a method that performs SendRequestSync() to a business process. However, I noticed that the business service lacks an OnProcessInput() method. Rather, it uses a method called General() which has the same sort of signature/structure that OnProcess input does--pInput as [Custom Message Class], Output pOutput as [Custom Response Class]. 

The method works as observed in a message trace but I am not sure why.

Motivation

This project was thought of when I was thinking of how to let Python code deal naturally with the scalable storage and efficient retrieving mechanism given by IRIS globals, through Embedded Python.

My initial idea was to create a kind of Python dictionary implementation using globals, but soon I realized that I should deal with object abstraction first.

So, I started creating some Python classes that could wrap Python objects, storing and retrieving their data in globals, i.e., serializing and deserializing Python objects in IRIS globals.

How does it work?

While reviewing our documentation for our ^pButtons (in IRIS renamed as ^SystemPerformance) performance monitoring utility, a customer told me: "I understand all of this, but I wish it could be simpler… easier to define profiles, manage them etc.".

After this session I thought it would be a nice exercise to try and provide some easier human interface for this.

The first step in this was to wrap a class-based API to the existing pButtons routine.

I was also able to add some more "features" like showing what profiles are currently running, their time remaining to run, previously running processes and more.

The next step was to add on top of this API, a REST API class.

With this artifact (a pButtons REST API) in hand, one can go ahead and build a modern UI on top of that.

For example -

Good Morning SMEs,

I am a .NET developer and new to using this IRIS Component. We are using InterSystems.Data.Clients ADO.NET component to connection to IRIS, I am able to open the connection but when i called Close, ADO.NET code showing connection is closed state in .NET code but in IRIS side it showing as connection is still open. The will close only after recycling apppool or closing IISExpress/calling application

Here are the steps I used to open the IRIS connection.

IRISADOConnection conn = new IRISADOConnection(connString);
IRISReference pError = new IRISReference("");
conn.

⏯ IntegratedML Update from the Field

In the good old days (tm) determining the size of the data, streams, and indices for a class/table was easy - you just ran %GSIZE and check D, S, and I globals respectively.

However, nowadays sharding, optimized global names, and indices in separate globals produce %GSIZE output looking like this:

            Global Size Display of /irissys/data/IRIS/mgr/irisshard/
                              1:35 PM  Dec 02 2020

          IRIS.Msg       1     IRIS.MsgNames       1     IRIS.SM.Shard       1

       IS.DGoWeK.

For our WSDL the portType value is being suffixed with "Soap" at the end.

When i update the the SERVICENAME parameter. in the Service I can update the start of the portType value. Is there a way to prevent the suffix being added?

You may have seen my series of articles on GlobalToJSON closing with Embedded Python.
And to me, Embedded means inside a Class and not PEX or other external variants.
The first variants showed that ePy is not an ultimate requirement. ISOS/COS may do it as well.
Here I try to position ePy inside IRIS.

How I can get current date/time on format YYYYMMDDhhmmss?

I tried $ZDATETIME($HOROLOG,8), but I got 20220606 17:59:56 and I want 20220606175956

Thanks

Hi guys,

A client want to programmatically list all namespaces and whether they are interoperability or not. Do we have apis or sql to do that? Thanks.

I've tried several methods of %SYS.Namespace but did not find it yet. Also when I use sql to select from %SYS.Namespace through jdbc, it always return an empty result set.

Hi there,

I'm passing a JSON object to the server as such:

{"key":"value","key":"value","key":"value"}

From the client:

- Build object

object=JSON.stringify(object)

-pass to server side method as %String

On the server:

s object={}.FromJSON(object)

Instead of getting something like

object=<OBJECT REFERENCE>[2@%Library.DynamicObject]

I get

object="991@%Library.DynamicObject"

I can't access that object using %Get as if says invalid OREF.

Hi developers!

Here is the score of technical bonuses for participants' applications in the InterSystems Grand Prix 2022 programming Contest!

Hey Developers,

🔥 You decide: VOTE HERE 🔥

     
How to vote? Details below.

IRIS Megazord

In the first article about IRIS Megazord, Henrique explains what drove us to create such an application. It basic is a composition of these previous project which we did:

• History Monitor
• Message Viewer
• ZPM Explorer

But we also started the development of a new feature, called Flow Editor. In this article we are going to know more about it.

IRIS Flow Editor

The aim of this feature is to test a new way to create IRIS Interoperability productions, as Henrique explained in the previous article.

It is very interesting to compare different BI technologies. It is curious to me what the differences are in functionality, development tools, speed and usability.

For this application, I chose a dataset with water conditions in various European countries. This is an open source dataset containing observational data from 1991 to 2017.

The team and I decided to make a model based on this BI dataset using IRIS BI, Tableau, PowerBI and InterSystems Reports (powered by Logi Reports).

For the frontend, we made a web interface in PythonFlask via Embedded Python.

Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS.
My personal problem is the use of DBeaver as a migration tool.
Especially as one of the strengths of IRIS ( and also Caché) before is the availability of the
SQLgateways that allow access to any external Db as long as for them an access usinig 
JDBC or ODBC is available. So I extended the package to demonstrate this.

Hey Community,

Exciting results from a massive workload to test InterSystems API. We'll describe how we're trying to push the boundaries of the current technology in the public cloud:

⏯ Running Large-Scale Rest API in the Cloud

Hi Guys,

So I've been following this guide in using a %Library.ResultSet with a  ClassName / QueryName as described in the first example.

https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic…

The code I've got so far doesn't work and is as follows:

set rs=##class(%ResultSet).%New()
set rs.ClassName="GMECC.DocmanConnect.Tables.vwNewGPs"
set rs.QueryName="GetRows"
set sc=rs.Execute("a")  If $$$ISERR(sc) Do DisplayError^%apiOBJ(sc) Quit
while rs.%Next() { do rs.%Print() }		

And the referenced class is

Class GMECC.DocmanConnect.

Maternal Risk can be measured from some parameters well known to the medical community. In this way, in order to help the medical community and computerized systems, especially AI, the scientist Yasir Hussein Shakir published a very useful dataset for training ML algorithms in the detection/prediction of Maternal Risk. This publication can be found on the largest and best known data repository for ML, Kaggle at https://www.kaggle.com/code/yasserhessein/classification-maternal-healt….

I have been developing this project for many years. He helps me a lot in my daily work as a DBA and full stack developer. This project has grown into a platform on which many of my other projects are based. You can read more about the project in the article. And I proposed this project for the contest, maybe it will be useful to you.

A few months ago, Jose and I were discussing the article Video Smart Data Services (Vision & Demo) from @Amir Samary and during that discussion, we started wondering what kind of feature would be nice to have on a future IRIS solution. 

One of the desired features is to have an IRIS iPaaS solution as I questioned here in this comment.

These last months gave me the opportunity to work with different projects and technologies, and put me in touch with applications like Tray.io or Workato, and now I can see how great an IRIS iPaaS solution could be.

Kidney Disease can be discovered from some parameters well known to the medical community. In this way, in order to help the medical community and computerized systems, especially AI, the scientist Akshay Singh published a very useful dataset for training ML algorithms in the detection/prediction of kidney disease. This publication can be found on the largest and best known data repository for ML, Kaggle at https://www.kaggle.com/datasets/akshayksingh/kidney-disease-dataset.

About the Dataset

The kidney disease dataset has the following metadata information (source: https://www.kaggle.

I think each of us has on the computer directories with photo files of relatives and friends, music albums of favorite bands and singers, as well as e-book libraries. I also have them, and I came up with the idea to implement a convenient interface for these files. You can read more about the project in the article. And I proposed this project for the contest, maybe it will be useful to you.

Hi, what’s the best way to check if your query return 0 records?

If $$$ISOK(sc) 	
    		{
   	   		 	Set tResult = sqlStatement.%Execute()
   	    
    			WHILE tResult.%Next()
    			{
					set tRecords = tResult.%ROWCOUNT
   		        }

				if (tRecords = "")
				{
					write "no records" 
				}
			}
