I'm attempting a first-time installation of IRIS for Health on my home Mac for eval purposes. I want to be able to install IRIS and Ensemble. I downloaded the package but it doesn't come with instructions, and I'm running into issues. Is there a straightforward install instruction set online, or does anyone have one you can pass along?


Thanks, Jim Winski

We have a need to track Database changes over time - down to the SQL level of granularity if possible. Such as: User xyz runs routine ^abc and we get something similar to a changelog that tells us: table A had this value updated, insert, update etc....

Is that possible using IRIS level tools (Audit Log, Journal File, etc...) , is there a way to convert the global sets and kills from the journals into SQL level changes?

Encryptions in IRIS

I saw that IRIS has some built-in%SYSTEM.Encryption Encryption functions, but what should we do when we see encryption AES/ECB/PKCS5Padding ? I wonder if there is a good solution?

最近应用到加密技术,看到平台具有内置的%SYSTEM.Encryption 有具有一些内置的函数,但是,应用过程中碰到加密AES/ECB/PKCS5Padding,我们应该如何处理?不知道有没有好的解决方式?

Hello Everyone,

We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager. 

Our aim is to implement a Microservices Architechture where Services are small in size,  bounded by contexts, autonomously developed, and independently deployable. 

We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.

Is there a way to automatically transform Object Script arrays to Python lists?  This code results in a list of arrays

Iter0 =  dbnative.iterator("HS.Data.OIDMapD")
for subscript, value in Iter0.items():
    print(f"subscript={subscript}, value={value}")

Here is the result:

subscript=1, value=2.16.840.1.113883.3.86ISCInterSystems Corporation

I suppose it would be too hard to parse this into a list, I was just wondering if there was a function provided to make it convenient and proper.

I believe that the Perl and Python bindings that exist on Cache / Ensemble do not exist on IRIS for Health 2020.1 ... is that correct?


Is there any similar documentation and samples (like below) , that show an example of how to run a basic Perl or Python script that connects with ODBC or whatever the recommended way?

greetings Community!

InterSystems Learning Services is working to identify and create libraries of high-quality learning resources for third-party technologies, platforms, and systems that are part of, integrated with, or commonly used with InterSystems products and technologies. we don't create content for these ourselves, but want to support our clients, external and internal, in learning about them and how to use them.

I am working with InterSystems API Manager product and I'm trying to solve an authentication problem.  In our implementation, API Manager accepts basic authentication.  One of the endpoints accepts OAuth2.  The request coming into API Manager is FHIR and needs to have basic auth in the header.  The OAuth token is passed to API Manager as a parameter.  I want to send FHIR to the endpoint with a Bearer Token in the header instead of the basic auth that came into API Manager.  Has anyone used a transformation plug-in to solve a similar issue?  I'm trying to solve this problem in API Manager ra

I am trying to figure out if we can extend a business process in IRIS. My Use Case is that I am developing RESTful Interfaces and my each REST Interface needs to go through certain processes before getting to the actual action.  

e.g. I have 2 REST Interfaces, GetPatient and GetEncounter. Both of these need to invoke "GetToken" Business Operation to go to the Authentication server to get an authentication token before they go ahead and hit the Business Operation to Get the data i.e. Patient or Encounter.

We are seeing performance issues in purging objects/tables that have parent-child relationships defined. Due to the number of child objects we're seeing very long duration to purge a single parent and all child tables. Is there a better way to do this and get a more performant purge task? I was thinking to purge the child tables individually first and then delete the parent is one way. Is there any other approach?

Byte[] property type

One of the REST APIs we need to call takes one of request parameter as a byte array. I am trying to create a message class and couldnt figure out which is equivalent type that corresponds to Byte[]. I need to read from a jpg file and then convert it to byte[] before i invoke this webservice. Appreciate if anyone can point me in the right direction. I can use %Stream.FileBinary class to store the jpg file after loading from a file. trying to figure out how to convert that to byte[].
