#InterSystems IRIS for Health

We are noticing some issues with the communication between our Arbiter and our servers. Looking at the following documentation to limit connections, and logging...https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GHA_mirror_set_config#GHA_mirror_set_agent_port

if I am configuring the ISCAgent on the arbiter, would we set 

application_server.interface_address=<ip_address>

to each IRIS server? Or does this mean to give it a specific NIC IP Address to use for communication?

You can avoid the error by specifying a stream object as the argument of %ToJSON() used when generating a JSON string from a dynamic object.

A code example is below.

USER>set temp=##class(%Stream.TmpCharacter).%New()

USER>set jsonobj={}

USER>set jsonobj.pro1=["a","b","c","d"]

USER>set jsonobj.pro2=["あ","い","う","え"]

USER>do jsonobj.%ToJSON(temp)

USER>write temp.Size
51
USER>write temp.Read()
{"pro1":["a","b","c","d"],"pro2":["あ","い","う","え"]}

See also the documentation for details.

With the world (as well as our own technology) moving to the cloud at such a fast pace it is easy (at least for myself) to get caught up in the little details. One thing I, and some clients of ours, had run into a couple of times was the necessity to specify the version of the images one plans to use with the IKO.

For example, one issue that often gets overlooked is the compatibilityVersion field for the IKO. Depending on which IKO you are using there is a default value (for IKO 3.6 this happens to be 2023.2.0, and for IKO 3.5 this is 2022.3.0).

Is it possible to configure mirror of the DB between two VMs using APIs like that one? I assume, based on the description, it can be done but on the same instance but I'm not sure how to do that for two separate VMs. I know how to use IRIS portal and set up Mirrored Members connections but now trying to automate that process.

Thanks!

I did not find any answer in the documentation and in the posts here to check if it also possible to migrate all databases from a native installed IRISHealth on Windows to my Community Edition in the container? Maybe anybody had tried this and can give me a hint.

Is there a way problematically to see what Operations/Services are attached to a EnsLib.JavaGateway.Service and if there are issues with the EnsLib.JavaGateway.Service to stop/start those Services/Operations that might be attached to it?

Thanks

In my previous articles, I described my Command Line Extension to NativeAPI.
Of course, this is also available for any other NativeAPI package.
So I created this example in Python as a demo.

Hi developers, 

We need to query and retrieve an image DICOM from a PACS by Accession Number.

Has anyone maked an IRIS development by this porpose?

Hello everyone,

I'm trying to perform a full backup using DO ^BACKUP, but the database keeps skipping the restoration. Does anyone know what I could do to allow the restoration?

Device: /usr/OLD/BACKUP.cbk
This backup volume was created by:
   IRIS for UNIX (Red Hat Enterprise Linux for x86-64) 2021.1
The volume label contains:
   Volume number      1
   Volume backup      AUG 21 2023 06:45PM Full
   Previous backup
   Last FULL backup
   Description
   Buffer Count       0
Is this the backup you want to start restoring?

Hi,

Here are the requirements for implementing a new project using FHIR and JSON.

The FHIR JSON resource types - Patient, Encounter, etc. - need to be converted to HL7 messages using DTL.

Does %JSONImport() allow direct conversion of JSON into HS.SDA3.Patient objects?

Could anyone suggest an easy way to convert FHIR objects for DTL use?

Hi All,

Been trying to setup a iris 4 health community version along with a webgateway bothing utilizing docker. The documentation seems a little sparse when it comes to configuring each of these to work together, especially when it comes to utilizing the Webgateway to front end the MGMT pages for Irirs 4 Health.

I know there is a github repo that has a docker compose file, but that doesn't see to provide a light on what needs to be configured in order for it to work.

Hello,

I have set up a Docker image with IrisHealth Community Edition and created a backup of all databases with the Management Portal. Obviously, the restore requires a different way, i.e. a terminal or session needs to be started to use a "Do ^DBREST".

Due to the manual first a session (which is probably same as iristerm terminal) needs to be started:

docker exec -it iris iris session iris

If I enter "DO ^DBREST", I get the answer:

<NOROUTINE> *DBREST.

I assume that when I start the session that way I get logged in as "USER", at least the prompt "USER>" indicates this.

Hey Community,

Enjoy watching the new video on InterSystems Developers YouTube:

By specifying the start and end values ​​of the IDs for which you want to rebuild indexes in the arguments of the %BuildIndices() method provided in the persistent class (=table) definition, you can rebuild only the indexes within that range.

For example, to rebuild the NameIDX index and ZipCode index in the Sample.Person class only for ID=10 to 20, execute the following code (the ID range is specified in the 5th and 6th arguments). 

 set status = ##class(Sample.Person).%BuildIndices($LB("NameIDX","ZipCode"),1,,1,10,20) 

$LB() is the $ListBuild() function.

I'm setting up a web application as CSP/ZEN to host a React SPA.  SPA's typically need to use a fallback page to deal with server requests based on the browser route, unless you use hash routing in the browser code.  Our requirements prevent us from using hash routing, so we need to deal with 404's - redirecting/fallback them to index.html - a very common practice.  I 'think' IRIS uses Apache under the hood, so I tried adding a .htaccess in the applications root directory - which did not work.  I found that CSP has an Error class, https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.

The FHIR® SQL Builder, or Builder, is a component of InterSystems IRIS for Health. It is a sophisticated projection tool used to create custom SQL schemas using data in an InterSystems IRIS for Health FHIR repository without moving the data to a separate SQL repository. The Builder is designed specifically to work with FHIR repositories and multi-model databases in InterSystems IRIS for Health.

The objective of the Builder is to enable data analysts and business intelligence developers to work with FHIR using familiar analytic tools, without having to learn a new query syntax.

In this article, I am demonstrating how to create a table column(formerly known as properties) with your custom datatype classes by using User defined DDL. Properties are the crucial member of the persistent class definition. Datatypes are essential to define types of values that are stored in a table column. In general, the datatype names of SQL different from Intersystems datatypes, such as VARCHAR = %String. you have the ability to create or modify a table by using these datatypes. Indeed, you’re creating the tables through DDL and you have your own datatype classes are already defined.

InterSystems Reports version 23.2 is now available from the InterSystems Software Distribution site in the Components section.  They are labeled InterSystems Reports Designer and InterSystems Reports Server and are available for Mac OSX, Windows or Linux.  insightsoftware elected to move from a  numerical number plan to a year-based numbering plan in 2023 so there are no versions 20 through 22;  versions increase from Version 19 to Version 23.  Note that the reports Server docker image will be available at a later date from the Container Repository.

When installing IRIS, all the system AUDIT events are not enabled.

What is the fastest way to activate all events?

I'm looking for an efficient way in DBeaver to filter system tables (ex: belonging to a schema starting with "%").

By using a user with the %All role, DBeaver shows us a long list of system schemas, which forces us to go down the list before accessing the user tables.

I have a problem. Occasionally, I am getting locked out of IRIS because of password failures. However, the failures aren't necessarily related to my password.  We are using VSCode, and I have installed one or two proposed APIs for use with the software (because that's just how I am; I want to learn the new stuff).

Today, I had that problem again. The step that caused the problem was most likely when I was trying to switch the branch I was using and updating within VSCode. Let's say I was switching from branch "1A" to branch "2B".

When creating the db using the Properties array, if I use a literal like "/iris/db/<instance name>/<directoryname>" it's created in the correct directory.

       set Properties("Directory")="/iris/db/InstanceName/DirectoryName"

but when it's executed with a variable, as in the example below,  it gets created in /iris/sys/<instance name>/mgr/

      set directoryPath="/iris/db/InstanceName/DirectoryName"
      set Properties("Directory")=directoryPath

 Is there any reason string literals work and variables do not?

Hello All,

How do I generate my own method for all properties in my class definition like auto-generated methods PropertyGet(), PropertySet(), PropertyGetStored().

Thanks.

You can see the free available space for the database using the radio button "Free Space View" in Management Portal: System Operation > Databases.

And it can be obtained programmatically by the FreeSpace query of the system class SYS.Database.

It sometimes happens that due to an adverse event the AUDIT database (IRISAUDIT) has grown to such proportions that the disk it resides on is full and the daily purge cannot be expected to reclaim disk space.

As IRISAUDIT is a system database required at startup, there is no question of attempting to restart IRIS after simply deleting IRIS.DAT from the <IRIS ROOT>/mgr/irisaudit/ database, nor of hot swapping, by system manipulations trying to dismount, replace, remount, since it is simply not possible to dismount it.

I cannot get any further hint from the error message in red in this screenshot. Is there any clue or details about the connection failure that I could look for?

InterSystems has also released IRIS as containerized deployments. This post is to demonstrate how InterSystems IRIS and applications those rely on IRIS a backend can be packaged into an image and be run in other machines in containers and how simple it is to do that.

A container runs image/s which have all the necessary executables, binary code, libraries, and configuration files. And the images can be moved from one machine to another, and  an images repository like Docker Hub can simplify that process.

I have used an application from Open Exchange for this demo.

It can be obtained using AllFields query of %SYS.ProcessQuery class.

For the details, please refer to the document Process (Job)【IRIS】／Process (Job).

An example of execution in the terminal is as follows.
