In this article, we’ll dive into the inner workings of the database management tool, exploring the architecture and technologies that power it. Understanding how the application functions behind the scenes will give you insight into its design, how it manages databases, tables, and how the API interacts with data.

We will discuss the core technologies used, including InterSystems IRIS as the primary database and Redis for caching. Additionally, we’ll break down the structure of the tables used and explain how the system handles data creation, retrieval, and manipulation through the REST API.

Hello community

I sent a http post message with a large message body (approx. 200 kB) to a standard EnsLib.REST.GenericService using a standard EnsLib.HTTP.InboundAdapter.

When inspecting the message in the message viewer I expected to see a HTTPMessage XML in the Contents preview, but I found a GenericMessage with no HTTPHeaders section. After a while, I found out that the display in the message's Visual Trace differs from what is shown, when going to the View Full Contents view in the Contents tab of the message viewer.

I also found out that the presentation in the preview window and also

Hi,

I tried to create what is know as a "class variable".  As far as I understand the only analogy to class variables would be the "class parameters".

I tried to use a class parameter but I cannot change its value at runtime.

Parameter STATUSES = {{}};

Property repr As %String;

Method %OnNew(repr) As %Status
{
    w ##class(Test...).#STATUSES
    w ..#STATUSES

    ...

}

When I get ..#STATUSES, it is a string like "5@%Library.DynamicObject". This is a string, not a pointer to an object.

I tried to define STATUSES as Parameter STATUSES  As CONFIGVALUE = {{}};  and change the value with

Hi ,

I am sending my DTL response (which is an xml stream) to an FTP out location.

My XML stream has CRLF , but after sending FTP'ing out , it displays as LF

Hi, Support Team

I´m working with Cache for many years, currently i have running version cache-2018.1.7.721.0-win_x64.exe

However we are facing some compatibility/requirements challenges, in that way i´m hereby request your support to provide next version/build of Cache 2018.1 (e.g cache-2018.1.9.xxx.x-win_x64.exe )

Nevertheless , I already downloaded IRIS for testing purpose if can also provide trial/limited licence for detail testing will be apreciated.

Thanks in advance for your attention.

I am trying to track down a problem we saw this morning with our TEST environment. We had a momentary issue where InterSystems HealthShare Health Connect could not connect correctly to LDAP. When we tried to login and could not connect to LDAP, the system would Delete our users.

the Test LDAP function would return a "Can't contact LDAP server". I went through the Certificates, made sure they had the correct permissions and were not expired.

At the OS level we had no problems using our LDAP accounts to authenticate against the server, so we know the server could connect to LDAP, the trouble w

Hi Guys,

I've created a webservice where a third party web application that can communicate with Ensemble via webservices to post and get data in from of JSON, first call is a post call to login with user/password and Ensemble responds with success or failure than the following get calls, but I've been advised that I also need to return a Cookie to control the exchange and the session for a specific user, I'm not familiar with Cookie so any suggestions, how can I create a an authentication cookie and do i need to add it to my next Get calls ?       

Thanks

Hi.

We are going to have basic patient demographic data coming in to Cache via a webservice. I thought that I should define the input as XML something like the FHIR format (with UK extensions).

In the past we've input XML streams and used the %XML.Reader to convert them to matching classes successfully, so I thought it would be easy. However, I've found that the FHIR format stores everything in attributes like:

  <gender value="male"/>
  <birthDate value="1982-01-23"/>

Looking in the Cache documentation here there seems no easy way to make a property match to an attribute of "value" with

I'm trying to authorise my app using OAuth 2.0 i Cache. Sadly I'm unable to exchange the authorization code for an access token.

I am able to redirect user to the /authorize page, where the user can login and approve my app. The user is then correctly redirected back to my app and a ?code parameter is sent back.

However when I try to make a POST request to the /token endpoint to exchange the authorization code for an access token I get the following error (from https://localhost:10443/oauth2/token which responds HTTP CODE 400 Bad Request):

  "error": "invalid_request",

Problems with Strings

I am accessing IRIS databases with JDBC (or ODBC) using Python. I want to fetch the data into a pandas dataframe to manipulate the data and create charts from it. I ran into a problem with string handling while using JDBC. This post is to help if anyone else has the same issues. Or, if there is an easier way to solve this, let me know in the comments!

I am using OSX, so I am unsure how unique my problem is. I am using Jupyter Notebooks, although the code would generally be the same if you used any other Python program or framework.

I am trying to use IRIS for Health as a Facade for an external FHIR Server, where IRIS provides the proper authentication. The client authenticates using a bearer token obtained from the IRIS OAuth2 server via a jwt client assertion. The IRIS endpoint, however, returns a 401 as soon as I remove the Unauthenticated access

Is there w way to make this work through configuration?
