All time

Good morning,

Thank you for taking the time to read and answer this question.

We need to find out how to display an EnsLib.DICOM.Document using LOGINFO, in the traces.

We have tried to use:

set writer=##class(%XML.Writer).%New()

set status=writer.OutputToString()

set status=writer.RootObject(..DocumentFromService)

set xml= writer.GetXMLString()

$$$LOGINFO("..DocumentFromService en xml: "_xml)

Share volumes across pods and zones on EKS

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

Hi -- at a customer site we have 8 Access Gateways, with a couple of different load balancers that decide which projects go to which subset of AGs.

We're about to go live with a project that uses a subscription, and we have that subscription pointing to one of the AGs. What if that AG goes down? The project is dead until the AG is back up. The subscription forces us to pick an AG that's registered in the Gateway Registry -- I don't see a way to get a cluster or load balancer address in there.

After creating a new dashboard the filters and favorites are not displaying on the left side.

The version info is as follows:

Cache for Windows (x86-64) 2017.2.1 (Build 801_3_18358U) Tue Jul 24 2018 16:38:29 EDT [HealthShare Modules:Core:15.032.8680 + Linkage Engine:15.032.8680 + Clinical Viewer:15.032.8680 + Active Analytics:15.032.8680

Thanks,

I'm new to Cache and trying to follow the Using Cache Studio PDF. In section 2.4.3(Adding a Zen form) it tells you insert the following code;

<button caption="Save" o select="zenPage.saveRecord();" />

Unfortunately that code fails compilation. If you try and use the tools there is no o select option nor a select or onselect option. I was wondering if anyone has used this PDF before and knows what the correct attribute should be?

When posting content there's got to be a better way to insert a screen shot. Saving to a file and then uploading is very primative plus the content isn't display in-line as one would expect these days. I don't want to "view a document" I want to see the image in-line.

Confluence does a really good job with this. Can we emulate this behavior?

High Availability IAM

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

Working on a project where I'm needing to make FHIR calls from my HealthConnect Interop production to Epic.

My issue is I'm not able to construct a valid JWT for the OAuth token retrieval that Epic will accept. I have the below code where I'm able to create a valid header and payload that I'm base64URL encoding and then trying to sign with my .pem private key file. However, Epic is not liking the signature portion of my JWT.

Fhir-HepatitisC-Predict

Processing FHIR resources with FHIR SQL BUILDER to predict the probability of developing hepatitis C disease

With the development of technology, the medical industry is also constantly advancing, and humans often pay more attention to their own health,
By learning and processing datasets through computers, diseases can be predicted.

Pre condition: Ability to use FHIR and ML
Firstly, our dataset is obtained from kaggle and transformed into FHIR resources based on patient gender, age, ALP or ALT, and imported into the FHIR resource repository
