Challenges of real-time AI/ML computations

We will start from the examples that we faced as Data Science practice at InterSystems:

  • A “high-load” customer portal is integrated with an online recommendation system. The plan is to reconfigure promo campaigns at the level of the entire retail network (we will assume that instead of a “flat” promo campaign master there will be used a “segment-tactic” matrix). What will happen to the recommender mechanisms? What will happen to data feeds and updates into the recommender mechanisms (the volume of input data having increased 25000 times)? What will happen to recommendation rule generation setup (the need to reduce 1000 times the recommendation rule filtering threshold due to a thousandfold increase of the volume and “assortment” of the rules generated)?
  • An equipment health monitoring system uses “manual” data sample feeds. Now it is connected to a SCADA system that transmits thousands of process parameter readings each second. What will happen to the monitoring system (will it be able to handle equipment health monitoring on a second-by-second basis)? What will happen once the input data receives a new bloc of several hundreds of columns with data sensor readings recently implemented in the SCADA system (will it be necessary, and for how long, to shut down the monitoring system to integrate the new sensor data in the analysis)?
  • A complex of AI/ML mechanisms (recommendation, monitoring, forecasting) depend on each other’s results. How many man-hours will it take every month to adapt those AI/ML mechanisms’ functioning to changes in the input data? What is the overall “delay” in supporting business decision making by the AI/ML mechanisms (the refresh frequency of supporting information against the feed frequency of new input data)?

Bootstrap Tables & CSP

Hello All,

We need to develop a small csp application which shows data in simple paginated / searchable table for business users.

It is to be built on an old version of Cache and is not a big full fledged application but something temporary. We can't use Zen and using a combination of csp & Bootstrap as bootstrap makes the pages look beautiful with little effort.

I have built the table in boostrap and it works fine with pagination and search working perfectly

Hi community,

I would like to ask how to correctly enforce SSL on all "developer traffic" -- that is Management portal and Studio connections -- on a Caché instance.

Given large developer permissions, I would like to eliminate all plaintext credentials on the wire.

Currently, we compile our own httpd with SSL support for Management portal, but this breaks Add-Ins for us, in particular the SOAP wizard. So I guess this is not the "canonical way".

Thanks for any suggestions

Jiri

Hello, I want to show a fellow DC member how to convert JSON file into HL7 message. I personally do not work with HL7. I set up a production with EnsLib.File.PassthroughService. It passes Ens.StreamContainer to BPL process. I call a DTL to transform StreamContainer to HL7 message. I run into an error:

ERROR <Ens>ErrBPTerminated: Terminating BP JSON2HL7 # due to error: ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''
> ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

The code is in this GitHub repo:

I was running the %File:FileSet class query, with my development user, but I am unable to run this query for an application user. Does anyone know what resource or service is needed to run this query? Assume the user has access to a certain directory on the file system needed for the query.

On second though, having tried almost all the available resources and services, perhaps the user doesn't have access to the directory. How to tell when the error is this:

Since now i have been working from external connection but i want to work with the SQL utility of Management Portal

i dont know how to do with several instructions like in other editors like this example

update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  80 where CodigoNum = '100' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '101' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '102' and Empresa = 'CO'

it returns

XMLExport and Validation

I interested on how others feel on this subject. In general terms when you have a class that extends from %XML.Adaptor and you call XMLExport no validation is automatically done as part of the XMLExport process. As an example if you do the following

Hello everyone,

I have a doubt, its possible to use interface like C# using COS?

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

Dear All,

I'm looping through a list with characters (Parenthesis, square brackets etc) and I wish to remove these from the list.

The for loop and IF logic are effectively removing these items from a list.

However the variable I use for the maximum number of loops carries on beyond the number of items of the list after removal.

In the output value for these I get the integer of the for loop instead of a null for the empty list fields.

I can see in the documentation that the end variable is not editable once the loop is started.

Hi All,

I am trying to create a production from a script(routine).

I am using the below way to create an empty production

Set oProd=##class(Ens.Config.Production).%New()
Set oProd.Name="Test.NewProduction"
Set oProd.ActorPoolSize=1
Set status=oProd.%Save()

But when i tried to start the production, i am getting an error as "Test.NewProduction" class does not exists.

Is there any other way to create the production via routine or terminal using commands as above?

IRIS configurations and user accounts contain various data elements that need to be tracked, and many people struggle to copy or sync those system configurations and user accounts between IRIS instances. So how can this process be simplified?

In software engineering, CI/CD or CICD is the set of combined practices of continuous integration (CI) and (more often) continuous delivery or (less often) continuous deployment (CD). Can CI/CD eliminate all our struggles?

WIN SQL is the normal editor used by most of the users .But we can't download large amount of data using winsql . So I have written a tutorial how to connect with a new Java based editor called Squirrel SQL which can easily download or export data in excel or any other formats. Also I included a Java JCBC connection program to connect with the IRIS database especially a mirroring/failover server.

When to use Columnar Storage

With InterSystems IRIS 2022.2, we introduced Columnar Storage as a new option for persisting your IRIS SQL tables that can boost your analytical queries by an order of magnitude. The capability is marked as experimental in 2022.2 and 2022.3, but will "graduate" to a fully supported production capability in the upcoming 2023.1 release.

The product documentation and this introductory video, already describe the differences between row storage, still the default on IRIS and used throughout our customer base, and columnar table storage and provide high-level guidance on choosing the appropriate storage layout for your use case. In this article, we'll elaborate on this subject and share some recommendations based on industry-practice modelling principles, internal testing, and feedback from Early Access Program participants.

I'm trying to create asynchronous Ensemble service/operation pair for SOAP passthrough.

General configuration:

  • Ensemble Service receives a message and immediately returns an answer to a caller (message received or some error)
  • Ensemble Service asynchronously calls Business Operation
  • Business Operation does guaranteed message delivery, etc.

Is it a viable approach?

Any tips? Ideas? Caveats? Code?

Seems like I can sublass EnsLib.SOAP.GenericService and change Sync to ASync (and provide a default reply immediately).

Debugging in HealthShare

Hi, if you develop production with HealthShare, you may have noticed there is a nice tracing feature available - HS.Util.Trace.Operations. This feature allows visually tracing debug information, in structured way. It complements good old logging macros like $$$LOGINFO, $$$TRACE and alike.

I use this feature a lot. However, it has limited functionality, it works nice with classes that extend XML Adapter, streams or data types, but it doesn't work well with arbitrary objects that do no extend from XML Adapter.

Hello Community,

I want to secure a SOAP Webservice (an EnsLib.SOAP.Service one, if that matters) adding a SSL/Username Policy to it. As im not sure how detailed my request here should get, ill try giving a detailed as-is description of my setup, what I've tried, how I tried to test the connection and what problems including some logs I ran into.

As a small foreword: I'm pretty new to the whole security aspect of intersystems and soap itself.

Hello,

We are in process of moving our first Production from development to test. We exported our project from Studio. On test server, we cannot Open the Production because it is not a valid production because nothing exists in Ens. Config.Production class. What are we missing? How do we add our Production in Ens.Config.Production?
