We would like to know how to get the Row Count of the SELECT query. We query external database via ODBC connection. 

//tSQL- is a select query. 

Set tStatus = ..Adapter.ExecuteQuery(.tResult,tSQL)

We are trying to get the row count of the retrieved records as below; but It doesn't return any value. 

tResult.%ROWCOUNT

End of support for CentOS

CentOS will no longer be a supported development platform as of the release of InterSystems IRIS 2023.3. 

CentOS had been a supported development platform to give developers a free-to-use equivalent to Red Hat Enterprise Linux (RHEL) for IRIS development.  As you're probably aware, Red Hat made significant changes to CentOS which moved it to being “upstream” of RHEL. This means it has bugs & features not yet included in RHEL, which can cause problems for developers building on the platform.

I am making a POST request to an API. In the case of an error, I don't know what parameters the response JSON will contain (they will change depending on the error). I am converting the response stream to an object but then I need a way to loop through all the properties and access their values. The following code is making the POST request, reading the response, and trying to add all the error messages to an array. But I can't iterate over the properties of the tProxy.errors object because it is a %ZEN.proxyObject. Is there a better way to do this?

Set tSC=..Adapter.Post(.tHttpResponse, , tPayload)
Set msgData = tHttpResponse.Data.Read()
Set temp = ..JSONStreamToObject(msgData, .tProxy)

If (tProxy.errors '= "") {
    Set errMsgs = ##class(%ListOfDataTypes).%New()
    Set itr = tProxy.errors.%GetIterator()
    While itr.%GetNext(.key,.val) {
        Do errMsgs.Insert(val)
    }
}

Hello Community,

I've enabled the JWT Authentication in my web application. I invoked the /login page to get the JWT and it creates an entry in %SYS.TokenAuth table. Is there any time span for the entries will rid out from the table automatically or It's  a manual process? Where can I find the JWT signature private/public key

Hi, How can I get an instance of stream which is a successor of %Stream.Object in a method that handles a REST POST request?

#dim request as %CSP.Request = %request
 set content = request.Content

This returns a variable of type %CSP.Stream which is totally useless, because %CSP.Stream does not inherit from %Stream.Object

Hi Community,

Will it hurt anything if I disable the user that installed IRIS, within IRIS? Does this cause a problem with background processes running or with the restart? I know the _Ensemble user is used to start/stop/restart objects within IRIS, just didn't see anything in the documentation about the user that installed IRIS.

Thanks

Hi There, 

I am having issues trying to obtain a JDBC driver which is backwards compatible with java 6 for a solution which will call my IRIS instance, I have already logged a WRC ticket which is looking unlikely that there will be any development to create a driver for such legacy tech. 

The Java 6 app is end of life, however won't be replaced until after my project goes live, hence why I ask the question. 

I am also investigating the use of an adaptor to bridge between Java 6 and IRIS 2022.

I am trying to move us to Securing the Management Portal using Apache and the Web Gateway.

Our Development environment/namespace only has 1 server, but both Test and Production have failover/DR mirroring containing 3 servers for Test, and 3 additional servers for Production. 

• Development - 1 server
• Test -2 server's setup for Failover, and 1 Async DR Mirror
• Production - 2 servers' setup for Failover, and 1 Async DR Mirror

In Test and Production, the mirroring is setup using an Arbiter and the VIP address is controlled at the Hardware level.

InterSystems announces its third developer preview for the 2023.3 release of InterSystems IRIS^® and InterSystems IRIS for Health^TM.

Future preview releases are expected to be updated biweekly and we will add features as they are ready.

Please share your feedback through the Developer Community so we can build a better product together. Initial documentation can be found at these links below.

I'm trying to run IRIS for Health Community Edition container on Mac (Apple chip) as follows

docker run --name iris -d1972

but it will error out to start

If I do not provide a durable volume, it will start w/o any issues.

Any thoughts about that?

Thanks

Hello Community,

I've created my FHIR patient profile and POST into FHIR endpoint in Intersystems FHIR Server.

http:localhost:52773/fhirr4/StructureDefinition

 I use the profile url into my Patient resource without the meet the profile requirements.

http:localhost:52773/fhirr4/Paient

The resource is stored successfully in the FHIR Server instead of a FHIR exception.

Why the resource doesn't validate with the mentioned profile?

Is this profile validation is really a intersystems FHIR server job or the validation implementation is available now  ?

Hello Community,

I have couple of question about the DynamicSQL.

1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.

2. What is the reason behind for a stored query prepared using %PrepareClassQuery() you must use the %Get("fieldname") method.

ObjectScript allows you to pass any number of arguments using arrays. Do it by adding ... after the argument name.

An example is as follows. In the example statement, the argument information is set in a global variable (a variable stored in the database) so that it can be easily checked after the method is executed.

The result of running it in the terminal is as follows.

Hi everyone, 

I'm attempting to compile a basic Python code on a remote server, but it appears that the compiler doesn't recognize the language.

The remote server is running a virtual machine with Oracle Linux Server 7.9 (64-bit), and it has IRIS for UNIX (Red Hat Enterprise Linux for x86-64) 2021.1 (Build 215U) [HealthConnect:3.3.0] installed.

When I try to compile a script that includes a Python ClassMethod, such as this "testpy.

I have a BPL that checks if at least one of the incoming OBX 5 values exists in TestTable. If the value exists it gets passed to Operation A and if it doesn't exist it gets passed to Operation B The lookup table has keys that range between 10 to 70 characters. However, the incoming message sometimes has OBX 5 values that are greater than 510 characters which causes the BPL to terminate and the message does not get sent to any operation.

Hi community,

I am looking for an implementation strategy to create/update organizations in a local ISC based FHIR server. Thoase organizations do have a certain dependancy to one another. For Organization resources the "partOf" property symbolizes that. It is planned, that a Interoperability Production (supporting FHIR Server) receives a bundle which contains a batch export of all organizations of a customer (Hospital). The task is to bring those data into the FHIR server create and/or update organization.

I was looking at conditional create/update since there a two major challanges.

I have run the query and got ORU^R03 message from SQL Editor and reprocessed the message, But pdf not opened and the base64 content looks truncated.

Is there a way to get full content from the message from query? Why the content is not visible in DB that I can see in Message Viewer?

Thank you so much for your time to read this,

Hi Team,

I am using  ##class(%Net.Cloud.Storage.Client).SingleDownloadBlobToFile 

Able to upload small files less than 100 MB, but when uploading large files like 800MB we are getting Java Memory error. java.lang.OutOfMemoryError Java heap space

I am using default JavaServer (javaServer param as ""). This happens in all three data types (File, Stream and Object)

InterSystems has made the decision to stop further development of the InterSystems Cloud Manager and label it as deprecated as of the InterSystems IRIS 2023.3 release.  InterSystems will continue to support existing customers using the technology, but it is no longer recommended for new deployments.

Customers in the cloud who are interested in deploying and managing an IRIS deployment with many systems are encouraged to consider Kubernetes and the InterSystems Kubernetes Operator, which has very similar functionality to ICM.

Hey Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

I recently started work on trying to Tighten Security in our Development Instance of IRIS that is running based on recommendations from our Audit as you might of seen from my other posts. I am currently trying to get into the Private Web Gateway Manager within IRIS as CSPSystem, but when I attempt to sign in nothing happens. 

I went through and reset the password in the CSP.ini and within IRIS for CSPSystem. I made sure it had the new GatewayRole per suggested

Introduction

We are in the age of the multiplatform economy and APIs are the "glue" in this digital scenario. Since they are so important, they are seen by developers as a service or product to be consumed. Therefore, usage experience is a crucial factor for its success.

In order to improve this experience, specification standards such as the OpenAPI Specification (OAS) are increasingly being adopted in the development of RESTFul APIs.

What is IRIS ApiPub?

I am trying to lock down security within our Development environment per requirements from a Security Audit that was done earlier this year. I need to try to limit access at a public level, access to cache users, and exposure.

I installed IRIS with the Lockdown method, and have configured my web applications, services, resources, etc.

When I go into my namespace, I am constantly presented with the following error when I try to start or stop an Object...

Cannot login as IRIS manager. Please confirm the '_Ensemble' user is enabled and is assigned the '%All' role.
