#InterSystems IRIS

Allow a question from a newbie 

1. Lets assume we have a global (matrix) [X,Y,Z] that is distributed across sharded nodes
2. Matrix size doesnt matter, but lets assume it holds 500 GB for the moment
3. I want to return all rows where f(x,y,z) is true. f() is an arbitrary function, i.e. f = x + 20(y*y) > z

Questions
Q1. Can such a computation (in ObjectScript) be moved and distributed from the client to the different sharded nodes for parallel processing
Q2. Where is that documented (incl. perhaps an example and performance measurements)
 

Thanks a lot
Frank

In one of my class, I use Stream.Read() method of the %Stream.Object class.

• Method OnRequest(request As Ens.StreamContainer, Output response As %Library.Persistent) As %Status
• {
•    SET sc=$$$OK
•    SET strRequest=request.Stream.Read(,.sc)
• ​​   $$$TRACE($L(​​strRequest))
• ....  

The Trace value gives 32,000. But the Read() method of the %Stream.Object class specifies 32,656 by default.

1. Method Read(ByRef len As %Integer = 32656, ByRef sc As %Status) As %CacheString
2. {
3.    Set len=0,i%AtEnd=1,sc=$$$OK
4.    Quit ""
5. }

Why ?

Best Regards.

Hi developers!

Suppose you have a Github repository with ObjectScript classes but without a Docker environment.

Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.

So in one sentence:

Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!

See the details below.

Hi Community!

Temporary tables are tables available for a current process only (and destroyed when process ends).

What are you approaches to creating temporary tables?

1. Process-private Globals storage can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage.  Here's how. Here's how 2.
2. InterSystems TSQL supports #tablename temporary tables. A #tablename temporary table is visible to the current procedure of the current process. It is also visible to any procedure called from the current procedure. #tablename synta

InterSystems IntegratedML (formerly known as QuickML) is ready for external beta, and is looking for some users to kick the tires!

IntegratedML is an all-SQL machine learning (ML) feature in IRIS that:
    • Gives users the ability to create, train and deploy powerful models from simple SQL syntax
    • Wraps "best of breed" open source and proprietary ML and "automl" frameworks such as TensorFlow, XGBoost, H2O-3, and DataRobot
    • Focuses on ease of deployment, so you can add predictions to your application with a single SQL function call

Just like the title says, I'm attempting to find a way to create a web application that instead of serving CSP files, it uses a dispatch class.
I searched for clues in the documentation, but the CSPApplication tag seems to be exclusively for CSP file-based applications.
I'm trying to avoid implementing a workaround such as using the Invoke tag to call the Security.Applications to generate the web application but I might be forced to do so, even though it's unpleasant if I had to say...
So, is there an official way to execute this task?

In Episode 5 of Data Points, @Bob Binstock joins us to talk about mirroring databases for high availability in InterSystems products! Most of the discussion centers around this process in InterSystems IRIS, with a few notes about the differences when tackling it in HealthShare. Take a listen and let us know your thoughts!

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions.While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue.Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours.I did not find any way, how to get the list of the open transactions from one place from ECP Data Server.We just migrated our Data server to 2018.1.

I'm working on developing Productions with java. The sample project has several intersystems jar files: -- intersystems-enslib-jms-3.1.0.jar -- intersystems-gateway-3.1.0.jar -- intersystems-jdbc-3.1.0.jar -- intersystems-spark-1.0.0.jar -- intersystems-uima-1.0.0.jar -- intersystems-utils-3.1.0.jar -- intersystems-xep-3.1.0.jar

I have the jar files, but where can I find them for download? Are they available on a maven repository somewhere?

Any help would be appreciated!

If a picture is worth a thousand words, what's a video worth? Certainly more than typing a post.

Can anyone clarify to me about the differences between these two classes?

People in this topic https://community.intersystems.com/post/using-class-queries-sqlstatement-versus-libraryresultset stated that %SQL.Statement (I am assuming they mean to talk about %SQL.StatementResult) is newer than %Library.ResultSet. But I don't really know what are the advantages of %SQL.Statement over %Library.ResultSet as the people in the topic somehow didn't mention them.

Currently I have a case and it seems like the %SQL.StatementResult doesn't have enough function to cover it:

I have to select with leftjoin

just wondering - is there any reason why IRISList doesn't accept decimal values?

.. IRISList would be very handy und useful - but if i have to build a wrapper to serilize/ deserilize decimals ...

Last time we launched an IRIS application in the Google Cloud using its GKE service.

And, although creating a cluster manually (or through gcloud) is easy, the modern Infrastructure-as-Code (IaC) approach advises that the description of the Kubernetes cluster should be stored in the repository as code as well. How to write this code is determined by the tool that’s used for IaC.

In the case of Google Cloud, there are several options, among them Deployment Manager and Terraform. Opinions are divided as to which is better: if you want to learn more, read this Reddit thread Opinions on Terraform vs. Deployment Manager? and the Medium article Comparing GCP Deployment Manager and Terraform. 

Loading your IRIS Data to your Google Cloud Big Query Data Warehouse and keeping it current can be a hassle with bulky Commercial Third Party Off The Shelf ETL platforms, but made dead simple using the iris2bq utility.

Let's say IRIS is contributing to workload for a Hospital system, routing DICOM images, ingesting HL7 messages,  posting FHIR resources, or pushing CCDA's to next provider in a transition of care.  Natively, IRIS persists these objects in various stages of the pipeline via the nature of the business processes and anything you included along the way.  Lets send that up to Google Big Query to augment and compliment the rest of our Data Warehouse data and ETL (Extract Transform Load) or ELT (Extract Load Transform) to our hearts desire.

A reference architecture diagram may be worth a thousand words, but 3 bullet points may work out a little bit better:

• It exports the data from IRIS into DataFrames
• It saves them into GCS as .avro to keep the schema along the data: this will avoid to specify/create the BigQuery table schema beforehands.
• It starts BigQuery jobs to import those .avro into the respective BigQuery tables you specify.

InterSystems and Intel recently conducted a series of benchmarks combining InterSystems IRIS with 2nd Generation Intel® Xeon® Scalable Processors, also known as “Cascade Lake”, and Intel® Optane™ DC Persistent Memory (DCPMM). The goals of these benchmarks are to demonstrate the performance and scalability capabilities of InterSystems IRIS with Intel’s latest server technologies in various workload settings and server configurations. Along with various benchmark results, three different use-cases of Intel DCPMM with InterSystems IRIS are provided in this report.

I want to send requests from custom BP with timeout and be able to understand that timeout event happened.

I thought that I need to implement OnTimeout method in my process (in either caller or callee), however it seems like OnTimeout  is never called.

Let's say we have this parent process:

Class Timeout.Parent Extends Ens.BusinessProcess [ ClassType = persistent ]
{
Method OnRequest(pRequest As Ens.StringContainer, Output pResponse As Ens.StringContainer) As %Status {
    set sc = ..SendRequestSync("Timeout.Child", pRequest, .pResponse, 5)
    if ($$$ISOK(sc) && ('$isObject(pResponse))) {

Hi all!

I'd like to share the code we used in a hands-on session in the last InterSystems Iberia Summit (Spain) about developing a simple Angular app using InterSystems IRIS as backend.

Hi,

Do you have any experience in server side pagination with IRIS using Angular on the client side?
Any idea on a typical SQL request on the server side?

Thanks!
Blaise

In February 2020, InterSystems published the technology to open source, expanding the possible use cases for it beyond embedded use from the InterSystems IRIS Data Platform. iKnow is open to community contributions to enhance the engine, language models and interfaces for use in-text exploration, information extraction, and machine learning use cases.

Dear Community, 

We're pleased to invite you to "ConferencIA", a conference about data and AI, which will take place on February 20 in Madrid, Spain!

At the event, both InterSystems experts and external thought leaders will share success stories and real projects, where AI is already a reality.

This error is sometimes seen while viewing a listing in InterSystems IRIS Business Intelligence:
ERROR #5540: SQLCODE: -99 Message: User <USERNAME> is not privileged for the operation (4)  

As the error suggests, this is due to a permission error. To figure out which permissions are missing/needed, we can take a look at the SQL query that is generated. We will use a query from SAMPLES as an example.

SELECT TOP 1000 %ID, DateOfSale, Outlet->City, %EXTERNAL(Channel) AS Channel, Product->Name AS Product, UnitsSold, AmountOfSale AS Revenue, (Discount * 100) || '%' AS Discount, Comment FROM HoleFoods.

Fastest Path to Possible - With Digital Innovation

Ladies and gentlemen, good news for our town.

It finally happened  - M was put in the cell.

And feels great there. Maybe it not a prison but an Excel cell.

Being there, he leads the whole M-gang. As well as conditional formatting in EXCEL.

Close integration of excel with the database provides a new convenient design tool.

Interactive reports, input forms, diagrams are generated only by m-commands in cells, without classical programming.

More detailed on https://github.com/mx-alex/MX

We will monitor the development of the situation and answer your questions.

best wishes

There is a special Query for reporting, it takes one cell of Excel. Example :

?$$omQuery 113^oPeat | Country   Country:Province   Date   Product:Date   Date:Product:-zr   | tn EURO | zrzr| | if Date'<%XD81,Date'>%XD82 |  set zrzr=zr,EURO=summa

The omQuery sets the structure and content of the required documents as well as filters and data processing procedures.

In one request, up to 9 reports are created, with subtotals by group. (5 here , 3 with:subtotals )

All issued documents retain the interactivity property - any manipulations with cells are displayed in excel and in virtual m-excel

If you had the opportunity to change something in the IRIS Interoperability Message Viewer, what would you do?

Our company is in the process of converting our software for use in Intersystems IRIS and one of the major sections of the software makes use of a custom statically-linked C library using the $ZF("function-name") functionality. During this, I found out that the process for setting up the C library to be used within the database platform has changed significantly between Cache and IRIS.

If you have used or still use the C Callout Gateway with Cache, then you will know that in order for Cache to be made aware of any functions provided in a custom C library to be used with $ZF("function-name"),
