Dash-Python-IRIS

We are happy to share interesting information with you, as well as tell you why Python is good, where it is used.

Among the most used libraries are NumPy and Pandas. NumPy (Numerical Python) is used to sort large datasets. It simplifies mathematical operations and their vectorization on arrays. Pandas offers two data structures: Series (a list of elements) and Data Frames (a table with multiple columns). This library converts data into a Data Frame, allowing you to remove and add new columns, as well as perform various operations.

%JSON.Adaptor thow an error with XData with JSON content

Hi Community,

for our forms validation we use XData to describe fields on server side.

These XData are in JSON like this

XData FormValidator [ MimeType = application/json ]
{
 {
  "username": {
   "required": true 
  },
  "email": {
   "datatype": "email"
  }
 }
}

When I try to use %JSON.Adaptor in same classes, IRIS throw an error at compile time

 ERROR #6301: SAX XML Parser Error: invalid document structure while processing Anonymous Stream at line 1 offset 23
  > ERROR #5490: Error running generator for method '%JSONGenerate:helora.worklist.

Data Drive Web Apps Questions

Hey there,

I posted a reply to the recent video https://community.intersystems.com/post/new-video-building-data-driven-web-apps#comment-132511
with a slew of questions.  Wondering if someone can take a look a address my questions on that post or on this new thread.

I find many InterSystems learning to be challenging to follow, but I"m not sure if it's because my work computer is so locked down that I don't have all the right tools and permissions I need to do what the tutorial asks, or if I'm not understanding the basics of Cache/IRIS, or both!

Java Connection Strategy

We are planning to build a REST API with the Java Quarkus Framework.

  • There'll be a connection pool;

  • The DataSource instance will be automatically injected from the connection pool;

  • We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.

Is there any pitfalls that we must be aware before taking this approach?

If you want to see some code the PoC can be found here.

Thanks.

Designing valid hierarchies in DeepSee

When designing a hierarchy in DeepSee, a child member must have only one parent member. In the case where a child corresponds to two parents, the results can become unreliable. In the case where two similar members exist, their keys must be changed so that they are unique. We will take a look at two examples to see when this happens and how to prevent it.

Example 1

There are a handful of states with a city named Boston. In my sample data, I have records from both Boston, MA and Boston, NY. My dimension is defined as:

City and State are simply strings in my case.

Monitoring Status of IRIS Production

Hello All,

I am looking for some ideas from people who have automated alerting in place for their Ensemble or IRIS productions.  

I want to start with basic things like, simply checking if a Production is up and running. Once this has been achived, I am looking to go deeper and implement monitoring on each interface level for things like, Queue Size, Errors and Inactivity.

Would appreciate if you can share some ideas. I have been exploring http://localhost:52773/api/monitor/metrics but don't see anything in there that tells me whether my Production(s) are running ok or not.

Thank you.

Streams and %IsModified after %Save

Found one interesting behaviour in one system with Ensemble. Some Request class has a property with type %XML.CharacterStream by design, this class is the heaviest request in the system, and with profiling journal files, it got about 40% of the file. When I counted all the sizes of such streams per one day and found that the real stored data is three times less. After deep inspecting the journal file, I found the first save of stream data, then removing previously stored data, and saving again and there were no reasons to change the content of the stream, it should be stored only once.

Example of ChunkedWriter

I'm thinking to try ChunkedWriter based on the documentation I'm reading to solve an issue but could use some clarification. Anyone that could provide a usage example of this down below?

To send a chunked request, do the following:

  1. Create a subclass of %Net.ChunkedWriterOpens in a new window, which is an abstract stream class that defines an interface for writing data in chunks. In this subclass, implement the OutputStream() method.

  2. In your instance of %Net.HttpRequestOpens in a new window, create an instance of your %Net.

Help required for Browser Support for VS Code Extension

Hi All,

We wanted to implement SSO(Single Sign On) flow from VSCode plugin to web application. In order to do this we need to launch new browser from VSCode (typescript code) and open application URL in this new browser. When trying to achieve this by using WebView  we are getting - X-frame-options issue and mentioning it is set as same origin. We have tried setting 'Content-Security-Policy' as well but not able to launch application in browser.

Issue assigning value to HS.FHIR.DTL.vR4.Model.Resource... meta.profile from within a DTL

 

Hi,

I'm using a DTL to convert a custom request class to various R4 FHIR resources using the HS.FHIR.DTL.vR4.Model.Resource classes. All is well with the exception of "meta.profile": when I attempt to hardcode this to a string value, the output is missing the value. This happens for several resources, specifically .HealthcareService, .Location, and .OrganizationAffiliation. I am able to get around this by doing an Insert() in a subsequent code block in a BPL, but was curious if someone knows why this would fail in a DTL.

no CreateMapPackage for cpf merge

We are developing some containarized cloud application level iris instances and using CPF Merge to do a lot of the initial buildout for the iris instance (i.e.  create databases, namespaces, map globals/routines, ecp setup, etc...)

I am trying to figure out how to get package mappings into a namespace config, via cpf merge if possible... ?

 

This is the document I am working from to develop the cpf merge file -
