I am currently managing environments running InterSystems IRIS and Caché on Windows servers.

I’m reviewing storage optimization best practices and I have a question regarding a specific Windows drive setting: "Allow files on this drive to have contents indexed in addition to file properties."

Based on my research, everything indicates that it is better to disable this option, especially on drives used by databases. However, I couldn't find a specific "official" stance in the documentation explicitly mentioning this checkbox.

I have installed IRIS community edition on a local directory in Redhat Linux 9.4.

Created a 10G database on a separate mount point directory  which comes out of a storage volume of 50G.

Also placed Journal and WIJ on 2 separate mount point directories  which comes out of two different storage volume of 50G each.

I want to take a snapshot and recover the snapshot on a secondary host and check the consistency of the database. 

As Storage snapshot will be taken, only Data, Journal and WIJ file placed on Storage volumes will be snapshotted.

Is there any Cache setting that needs to be checked while configuring IRIS Community Edition 2025.2 and does it impact WIJ recovery.

Also I have kept Database, WIJ and JOURNAL on the same snapshot group with Consistency . Is it the recommended settings? Am I getting the WIJ mismatch error due to this setting?

I have a global with multiple nodes : 

^A("ABC") = ""
^A("DEF") = ""
^A(123) = ""

How to create a new single node in that global, in a way it's always at the end of the global (eg: this will be the very last node being enumerated)

I end up with this code but maybe there is a cleaner and simpler approach : 

set ^A($char(65535)) = "" //should be bigger than any character inserted
set ^A($char(255)) = ""   //some systems does not seems to support >255 characters, this might be safer

I only need to write it once, this code is not intended to be used in a loop or something, just to add something at the end (like a footer).

Hi 

Is there a sample that I can use to create a simple alert code, and do I need to set up or pay a service provider? 

Thanks

I am stuck at a crossroad and was wondering if I could get a second pair of eyes to help with a query that I am sending from a Task to a Service to process some data.

I have a Linked Table (view) that points back to a MS SQL View that I am trying to query. However, my execution keeps either failing or not returning any rows. When I take the SQL Query and execute it within the Management Portal I get results, however Cache is not seeing it when trying to execute this code.

I am trying to create a task that has a variable property that a user can specify DaysBack but it keeps coming up blank when I ask the system to get the date as of DaysBack from the CURRENT_DATE. Can someone tell me why I am not getting a value back in my tDate variable?

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition

Property DaysBack As %Integer [ InitialExpression = 1 ];

    try{
        set tDate = ""
        &sql(SELECT DATEADD('day', -:daysBack, CURRENT_DATE) INTO :tDate)
        ZWRITE tDate
        set tSC = ..SelectTerminations(tDate)
        $$$ThrowOnError(tSC)
    }Catch (tException) {
		Set tSC = tException.AsStatus()
	}
	Return tSC
}

Method SelectTerminations(pDate As %DateTime) As %Status

Hello, how are you?

Using Healthshare for Interoperability, we often see a wide variety of encoding issues. Some happen when transforming XML to HL7. Some happen the other ay around transforming HL7 to XML.

Is there a valid way to understand which encoding needs to be used?

I ask, because we use SOAP or REST or TCP HL7 services.

And we deliver messages with TCP HL7, SOAP, HTTP Operations.

And we often face this issue where special characters like ñ or á, are not encoded correctly.

Thanks for your replies.

I am issuing "iris freeze <instance_name> to freeze the instance. I want  confirmation that no IO is going to the database so taht I can take a snapshot.

How to obtain an evaluation license for testing ECP and FHIR in Community Edition 2025.3?

How do I download IRIS Community Edition 2023.2? What is the download link?

Hello everyone,

I’m trying to find a way to manage globals from our Java application. We have two separate features:

• Managing tables normally using SQL

• Managing globals, since some globals exist without class or table definitions

Cache version : Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.1.1 (Build 108U_SU), Thu Jul 7 2016 09:39:04 EDT

I tried to retrieve the globals tree, update node values, and append nodes using SQL by calling stored procedures, but I couldn’t find any procedures for adding, updating, or deleting nodes.

I also tried using cacheextreme.jar

When using VS code with multiple workspaces it requests "The extension 'InterSystems ObjectScript' wants to sign in using InterSystems Server Credentials. 

Other than having multiple workspaces per environemnt (which never really works for me in principle as i end up code comparing in one manner or another) is there a way to only have intersystems log in to VS code whenever you open an actual workspace itself i.e. click on dev not on loading vscode. 

This would also get around errors of "unauthenticated access rejected by" errors as VS code tries to log in without the password first. 

Hi Team,

Hello,

First of all thanks for reading this question.

We are migrating our old HealthShare instance to the newest version.

We need to export all the Tasks.

We have tested:

I have installed personal community but still can't see the configure personal community option here.  this is linux 

Hi everyone,

I am currently integrating a Sysmex analyzer with InterSystems Ensemble/IRIS using a Moxa NPort 5110. I have successfully verified the physical and serial layers, but I am facing two specific issues: a protocol sync error and a persistent TCP connection state.
Environment:
Interface: ASTM.

Gateway: Moxa NPort 5110 (TCP Client Mode).

Server: Ensemble Business Service (EnsLib.ASTM.Service.TCPService).

Port: xxxx.

Current Status & Observations:
Serial Layer: Verified. The Moxa "Async Monitor" shows RxCnt increasing when the instrument sends data. Hardware pins (DSR/CTS) are ON.
