Now I want to return a large amount of data to the front end. The string length has reached 40000 +, and the returned data needs to be encrypted by AES + Base64. I can convert the string into a stream. AES can use the AESCBCEncryptStream method to encrypt, but Base64 has no stream method。Anyone who get the solution  would you kindly share the solution please。

Any help would be appreciated. Thanks!

I'm currently working with a developer to add IRIS/Caché functionality to his HL7 analysis tool that would allow its users to extract messages directly from the Ensemble message store. IRIS for Health Community Edition has been a great aid in debugging this, but I keep banging into the 5 connection license limit with Studio, the Management Portal, an IRIS terminal session and a client database connection using either ODBC or ADO.NET.

Hi all,
By using VS code, I want to copy multiple files to local directory, then sync them to server, but I can't find where local directory is stored?
In Atelier IDE, I could open a view of server and can copy the code to the project, then code is saved in the local directory. When I copy multiple files to the local directory -> choose sync in Atelier -> the code will be synchronized to the server
How to do this from VS Code?

 I am looking for any pointers on how Intersystems IRIS Health can monitor a filesystem/Folder that user/s /applications can drop in CSV files via FTP and load the file  to the IRIS DB . I understand that I will need create a record map for the CSV files, I am looking for any configuration references on how how to process files using file inbound adapters  with the  intent to pick up the CSV  file as they are dropped in the  target location and pass it to a Business process and ingest into the IRIS database 

Any help would be greatly appreciated ...

Hi All, We have been using DeepSee which has been the integrated Analytic Dashboard built over Cache Cubes. It works fine but it's visual capabilities are limited and most probably is getting phased out. If I am not wrong, Tableau is the suggested alternative to DeepSee . It is expensive and a big and considerable shift from existing technology I wanted to get an opinion of the community as to these few key points - What other BI tools others have been using with IRIS and what have been their experience - For which tools are the best inbuilt support / api's avaialble in IRIS

We have a situation where we want to save the patient photo (or any other attachment) received via FHIR to a persistent property without decoding it. When it is sent out again using FHIR is is stored in the encoded format and need not be encoded. We do not need to decode it for our application. We always use it on another system that retrieves it or saves it via FHIR and therefore it is always received or sent embedded in JSON.

I'm new to Iris for Health and I'm trying to get some experience using it.  I've subscribed to the Intersystems Iris for Health software in AWS marketplace.  I successfully spun up the EC2 instance with the default security group.  The try-iris instance is healthy and successfully starts within EC2.  I've also successfully changed the default password too.

 However, I'm unable to authenticate into the management portal.  The portal launches okay though I keep getting an access denied.  I'm also unable to authenticate into a session from the EC2 instance.

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.

While I can query the HL7 message class EnsLib.HL7.Message (EnsLib_HL7.Message for SQL) to my heart's content in the SQL Shell or the Management Portal's SQL page, I can't seem to SELECT anything other than ID/%Id from an ADO/ODBC client. Properties such as TimeCreated, Name, MessageTypeCategory, etc. all seem to prevent the query from ever completing EXCEPT when I provide the ID as part of the WHERE criteria.

This works fine in the Management Portal and Shell:

 A device is sending me HL7 messages (ORM^O01)

the framing is set to "None"

and i get the following error:

3 Segments
Build Map Status = 'ERROR <EnsEDI>ErrMapRequired: Missing required PID element at segment 2 (PID)'
'ERROR <EnsEDI>ErrMapRequired: Missing required OBR element at segment 2 (PID)'
'ERROR <EnsEDI>ErrMapSegUnrecog: Unrecognized Segment 2:'PID' found after segment 1 (MSH)'

i seems that there framing chars in at the beginning and end of each segment

(in Hex)

Hi Everyone,

I've been working on deploying an IRIS for Health environment in EKS. There is a video session in the InterSystems learning portal about this feature but I have not succeeded in finding the proper documentation and resources to use this in my Kubernetes cluster.

Has this been deprecated/discontinued? Any idea where can I find the resources? Should I stick to StatefulSets instead of using the IrisCluster resource type provided by this operator?
