Hi community.

I'm trying to create a "setup" method to be called on a batch script but i'm getting the error <INVALID ARGUMENT> when I pass a string as an argument to this method.

The idea is to call the method with a folder as the parameter, for example:

##class(test.MyClass).MyMethod("D:\path\to\my\file.json")

My class (just for example)

Class test.MyClass

I've been wondering about some code that I have come across a lot over the years.

Let's assume I have class Cinema and class Film.
Conceptually the data in these classes are never really physically deleted but only flagged as such, due to business requirements.

What I find is that developers tend to create a 3rd class "CinemaFilms", in a child relationship to parent Cinema, with a reference to Film. Rather than a one-to-many between Cinema and Film.

Record Map - MAXLEN

I am trying to read in a data file via a Record Map and I am getting the following error...

ERROR #7201: Datatype value '030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_B452' length longer than MAXLEN allowed of 50 > ERROR #5802: Datatype validation failed on property 'osuwmc.MatSys.DataStructures.MatSysIVT.Record:Bin', with value equal to "030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_030121_B452"

Suppose we need to store millions of values temporarily, that means, we don't care about them if we lose them but our application use them to get realtime information. Should I use Cachetemp or whatever other DB without journaling enabled? If answer is Cachetemp, shouldn't be a problem if we decide to scale using App Server + ECP? I'm not sure what would happen with the app logic in such architecture as I guess I couldn't map and share cachetemp...

Any idea/suggestion?

We have a Cache database in Azure, and want to expose it as an OData source (link).

My first attempt was to use Microsoft's Visual Studio 2017 and Entity Framework to create the data models...but it seems as if EF and Cache don't work together. (I do have those instructions from 2013, but they don't work. (See other post. Best answer seems to be "migrate to IRIS 2019.1.")

Is there any other form of OData support?

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

I'm using Caché as an OAuth authorization server and I want to accept the password credentials grant type. I've found that if I make an authorize request, the Caché authorization server requires some URL parameters that shouldn't be required in password grant (redirect_uri, state, scope, and response_type). If I include these parameters, it calls my DirectLogin() method instead of just calling ValidateUser() as I would expect from the docs. I have two questions:

Client Websockets based CSP

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

Client Websockets based on Node.js

It will demonstrate the wide range that is openend by making use
of the power embedded in Node.js and its adapter to Caché, Ensemble, Health,..*
Node / JavaScript have wide reputation to work as a WebSocket client.
By using the Caché adapter it becomes easy to control it and to consume the results as a
Client for WebSocket Servers and to collect the replies in Caché, Ensemble, ..

I used node-v6.16.0-x64.msi and cache610.node as cache.node

You provide a Global for input:

Our development server is set up to automatically keep the .INT code of compiled classes and routines, but the live servers are set to not keep the .INT code.

I know how to set the system to keep this code ($SYSTEM.OBJ.SetQualifiers() ?) but what are the ramifications of keeping this code on the live servers? Is it just a space issue? I always thought it was to keep the code more private.

Hello everyone,

I'm using Atelier 1.3. When we configure a server and use HTTP to connect, works fine. But when we activate the Secure connection option I get the Unregonized SSL message, plaintext connection?

Do I need to perform any configuration on my server so that Atelier can access a secure connection?

Does Intersystems Ensemble support (for LGBTQ+) gender code "U" in Healtshare? Specifically for the clinical (or physician) viewer?

Test shows the gender code is consumed without error and stored, but the viewer does not present it except (as far as I can see) in the patient search drop-down.

The 2.3.1 HL7 ADT schema code table lists "U" as a supported option.

Would this require customization in the viewer code to support this?

I'm looking for options to create multiple DFT HL7 messages based on data contained in a ZCO segment in a single inbound DFT message. I have the following ZCO segment:

ZCO|CCC^Charge Code|1306794,1071301,23510,1071424|MFCD^Charge Code|14232,3542|||||

In this example, I need to create a new DFT message based on the data contained in ZCO:2. Each code needs to be in it's own DFT message and put in FT1:7.1. The number of codes will vary for each inbound message, but each code will need to create its own outbound message to the client.

Hi all!
I need to call an API that has the following characteristics:

  • Content-Type: application / x-www-form-urlencoded
  • Authorization: (with a "Bearer" token)

In the body the information is given through the form data.

I can not find documentation on how to make this call and how to get the answer (JSON).

Could you help with an example?

Thank you

Hello,

I am new to InsterSystems Cache - having a SQL Server background. However I am dealing with a Third Party who use InterSystems Cache to hold some of our data. To do some analysis I need to view a backup of the database. They are prepared to send me a backup.

My question is - how can I view this backup ( would this be the CACHE.dat file?).

Do I effectively need to have an installation of CACHE on my machine to be able to view this? Is it possible to view it from SQL Server?

Any help would be appreciated.

Thanks

Colin
