Reviewing the different articles that I have published, I realized that I needed to explain a very practical functionality within our EMPI (Enterprise Master Patient Index) and it is none other than the notification of registrations and links to systems external to the EMPI.

This functionality is frankly useful in a tool such as EMPI and especially in environments such as healthcare in which it is very common for the same patient to have their data duplicated in different systems and in the end it is necessary to uniquely identify it. The solution to reduce this amalgamation of records is to

Hello,

We had a weird behavior of task manager in mirror async backup-failover pair:

1. server 1 was primary, server 2 backup for over a month, as there was no automatic failover (switch) both had IRIS up for over a month
2. We manually switched making server 2 primary
3. The tasks that had this issue were set to "run on Primary only"
4. Task manager started to execute tasks every minute: we noticed that "Next scheduled time" is always calculated in past date, and progressing by the task interval (e.g. a task that supposed to run every hour will have "Next scheduled time" in the past e.g. 2025-

I have a rest API Class used for getting data from Cache 2018 version.
I have single route '/callfuntions'
I send the following parameters to the API :-  className, methodName, params
I use $CLASSMETHODto execute and send the result back to the client.

If I make more that 10 to 12 requests in quick succession, then it stops sending data.

if I wait for over 10 seconds it allows me to send more requests to the API.  How do I resolve this?

Question:

How can I create, change etc. Security entities (like Users and Roles) programmatically?

Answer:

You can use the Security package classes in the %SYS namespace. For example Security.Roles or Security.Users.

Of course in order to perform these actions the user will require the needed authorization.

Here's a small example using Security.Roles:

// Create a Role
%SYS>Set status = ##class(Security.Roles).Create("testRole","a test Role","%Development:U,%DB_USER:R")
 

// Creation was successful
%SYS>Write status
1

// Now lets examine the Role created
%SYS>Set status =

Hi community,

The aim of this article is to explain how to create messaging between IRIS and Microsoft Teams.

In my company, we wanted to monitor error messages, and we used the Ens.Alert class to redirect those error messages through a Business Operation that sent an email.
The problem was that we sent those error messages to a support account where there were many emails. We wanted something specific for a specific team.

So we investigated how to make these messages reach the development team directly and they could have, in real time, a notification of an error in our production.
In our company we use Microsoft Teams as a corporate tool, so we asked ourselves: How could we make these messages reach the IRIS development team?

If anyone has a custom checklist of tasks that must absolutely be done when doing this upgrade to make sure everything is included and nothing is lost or destroyed, we would greatly appreciate it? We have the generic checklist provided on the support websites but we run custom build classes, ftp, tcp-ip, batch, etc.

Thanks,

Jonathan Harris

For background, I've developed code that relies on %JSON.Adaptor functionality across an entire package of classes in our codebase. In regenerating these classes with %JSON.Adaptor as a superclass, I've encountered compilation errors from the JSON adaptor generators in certain classes, triggered by certain property types or parameters that are incompatible.

There are two causes for these compilation errors: either 1) the property is computed, and therefore certain property methods in the code generated by the JSON adaptor, such as ..SetObjectId(), do not exist, or 2) the property is an array

Hello Community,

Is it possible to retrieve/find all the names of subroutines, procedures, or functions from a deployed routine?. in the routine below, how can I extract names like x2 and execsql? I’ve just tried using openId on %RoutineMgr  but it didn’t help.

xdeploy.mac
xdeploy
 quit
x2 ; test1write123q
execsql(sql) ; test2Set tResult = ##Class(%SQL.Statement).%ExecDirect(,sql)
 Return tResult

Thanks

I'm playing with %Net.DB.Iris and stumbled over a mystery

set con=##class(%Net.DB.DataSource).CreateConnection(host,...)
set srv=con.CreateIris()
write srv.ClassMethodValue("%SYSTEM.Util","InstallDirectory")

Entering the above lines (in a terminal session) on my local instance yields the correct answer for:

host = "localhost"
host = the real IP of localhost (i.e. host="192.168...")
host = "10.x.y.dev" customers development system (over a VPN tunnel)

but for

host = "10.x.y.tst" (customers test system) I get an error:

We are attempting to send HL7 messages over to CBOARD NetMenu over HTTP using SSL. We set this up using the EnsLib.HL7.Operation.HTTPOperation adapter. When we attempt to send the message we are receiving 

MSH|^~\&|||DIETOE|A6M0|202505131437||ACK^HTTP^415|00|P|2.1 MSA|AE|9165602|HTTP (N)ACK 'HTTP/1.1 415 Unsupported Media Type'

The vendor mentioned something about putting a SOAP/XML wrapper around the HL7 message but isn't that what the HTTPOperation adapter does? Why would we be getting Unsupported Media Type. How would we go about setting the Media Type for the HTTP HL7 message?

Hello Community,

I executed the below query in the %ZLANGC00.mac routine. It returns results when using dynamic SQL, but not with embedded SQL(returns 0). 

 &SQL(SELECTcount(*) INTO :Cnt FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Write "SQLTablecount : "_Cnt,!
 Set tResultSet = ##class(%SQL.Statement).%ExecDirect(,"SELECTcount(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Do tResultSet.%Display()

Thanks!

Hello,

I have a problem with the deployment. When I deploy using the Ens.Deployment.Deploy class, I no longer receive the logs in the terminal. However, the deployment went well, I see it in the history on the portal.

It works on our environment, but not on the client's.

Set tSC = ##class(Ens.Deployment.Deploy).DeployCode(chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0.xml","SVCCLI.ProdClient",1,chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0_rb.xml","L",chemin_"GESL_SVCCLI_DEPLOY_CPT-243_V4_0.log",1,1)

According to documentation, quotation: "$THIS contains the current class context.
The class context for an instance method is the current object reference (OREF).
The class context for a class method is the current classname as a string value."
 
As my example below shows, either the documentation or the implementation (or both) is wrong, I always call a class method (Value) and expected the class name as the return value but got either the class name or an OREF. Moreover, if I repeat the call, I get another values. But why?
Does anyone have a clear explanation (for an aging brain) or have I misun
