Introduction

InterSystems would like to optimize IRIS to take advantage of modern CPU instruction set extensions.  That’s great for product performance, but how do you know if your CPU will still be supported for new IRIS builds?  Here’s how to know your CPU’s microarchitecture family as well as how to find out your CPU’s specific instruction set extensions.

This is probably not the right place, but I don't know who I can reach out to... I am trying to configure an Apache/Web Gateway to our instance of IRIS so we are no longer using the built-in PWS. Can anyone point me in the right direction to configure Apache/Web Gateway to repoint

http://<server name>:52773/... to the https://<server name>/...

gateway so our users will not notice? How do I do this in Apache, do I need to modify httpd.conf or the ssl.conf file? What is the correct syntax...

This is what I tried to do in the httpd.conf file

<VirtualHost *:52773>
    ServerName int-lxiris-vd01.osumc.edu
    ServerAlias int-lxiris-vd01 int-lxiris-vd01.unix.osumc.edu
    Redirect permanent / https://int-lxiris-vd01.osumc.edu/
</VirtualHost>

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

We are moving away from Delegated Authentication in which I stored a username and password for our LDAP in a GLOBAL to be called by ZAUTHENTICATE.

Is there a way to pull in that GLOBAL into the LDAP Configuration within the Managment Portal instead of having to manually enter it? There seems to be an issue with Copy/Paste that the password isn't being set correctly when I use Copy/Paste.

Else I just export/import the LDAP Configuration from 1 server to another and manually update the Certificate to point to the correct file.

Thanks

Is there a size limit to what a %Library.DynamicObject define variable can hold?

For routines (*.mac)

You can hide the source by exporting/importing only the *.obj that is generated after compiling the source program.

The command execution example specifies EX1Sample.obj and EX2Sample.obj, which are generated by compiling EX1Sample.mac and EX2Sample.mac, as export targets and exports them to the second argument file.

After moving to another namespace, I am using the exported XML file to perform the import.

Hello Community,

The Certification Team of InterSystems Learning Services is excited to announce the release of our new InterSystems HL7® Interface Specialist Recertification Project If you hold the InterSystems HL7 Interface Specialist certification AND your certification's expiration date is within 6 months of today's date, you can get recertified by successfully completing the recertification project. Completing an InterSystems recertification project is one of two options a certification candidate can choose to get recertified (the other option is to take the new version of the exam).

Hi colleages!

This is very easy to setup a FHIR server in InterSystems IRIS for Health.

It could be even one IPM command with this package:

USER>zpm "install fhir-server"

But which FHIR portal could you recommend to use?

I used to work with this one, which is very easy to install too:

USER>zpm "install fhir-portal"

 but it doesn't work at the moment and I'm not sure if its main contributors @José Pereira and @Henrique Dias plan to support it.

What do you use? What do you recommend? Ideally installable with IPM package manager. Thanks!

Hello Community

IRISTEMP database consumes more disk space and make the production instance down when running Bulk SQL queries (maybe other processes aswell)

Is setting up the "Maximum" size it resolves the problem?. Is this setting impacts the performance? 

What are the approaches to resolve it

Hi,

An exception occurs randomly. I expect the value of ^TEST to be 20, but it's not. Did i miss something like closing, flush the stream or locking the global?

Does the Version of the Web Gateway have to match the version of IRIS that is currently running? Or are they independent of each other since they are different components? I am looking to install the Web Gateway (non-PWS) as we move forward with securing our Management Portal and VS Code connections using TLS.

Thanks

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Error:

PHP Fatal error:  Uncaught PDOException: SQLSTATE[SL009]: <<Unknown error>>: [unixODBC][Driver Manager]No columns were bound prior to calling SQLFetch or SQLFetchScroll (SQLFetchScroll[0] at /builddir/build/BUILD/php-8.1.20/ext/pdo_odbc/odbc_stmt.c:547) 

InterSystems will end support for using the VxFS filesystem with InterSystems IRIS and label it as deprecated as of the release of InterSystems IRIS 2023.3.  InterSystems will continue to support any existing customers using the technology, but it is no longer recommended for new deployments.

VxFS had only been supported on SUSE Linux.  Impacted customers are encouraged to migrate to XFS or another supported filesystem.

Customers with questions should reach out to their account team or contact me directly.

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.

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

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.

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.
