The ^%GCMP utility can be used to compare the contents of two globals.

For example, to compare ^test and ^test in the USER and SAMPLES namespaces, it would look like this:
*In the example below, 700 identical globals are created in the two namespaces, and the contents of one of them is changed to make it the detection target.

One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Hello to all my fellow Cache Developers/Experts out there :)

The purpose of this post is to get input/feedback regarding an issue we are having with our Cache LIS web-based application not being able to remove locks that were taken under a separate process.

Here is the background of how the LIS does the locking and details about the issue:

Given the code below, I need help with getting the collected column widths from the Demo.Configuration table and stored in the columnWidths zne page property. As I understand it, I should be able to retrieve it using zenPage.columnWidths in the setColumnWidths or dgRender clientMethods but the alert is showing that it cannot be retrieved as it shows a value of Null. Once I can retrieve those values, then I want to set the widths of the colmns of the dynaGrid according to the values in the ^Demo.Configuration table.

Mirroring only synchronizes database files.

To synchronize other files required for your application (CSP files, images, documents, etc.) between the two servers that make up the mirror set follow one of the approaches:

  1. Place those files on a shared disk by introducing a NAS or similar device
  2. Or use file sync software to synchronize files between two servers.

Dear, Community!

I have a concern about using %Stream.TmpCharacter for storage purposes. Reading the class's source code, I can understand a bit about how it works. But I'd like to know from the community how it actually works. Is it necessary to use the .Clear() method to clear this buffer, or is it done automatically upon disposal?

Note: Please forgive my poor English.

I'm trying to catch some WorkQueue errors that are happening on 2019 but not on more recent versions.

I'm getting an error when trying to call a class method via a workQueue. It functions properly in 2024.1. When calling the method, it immediately errors. I have logging at the top of the method that never gets set.

The error being returned by Iris is simply an "ERROR #5039: An error occurred while calling function s %sc=##class(|"NS"|Path.To.Class).ClassMethod(.%p1,.%p2)"

The parameter counts match and are appropriate for the method.

Hello,

I'm trying to get the Reply Action Code to work with the error message text.

I have this ACK:

MSH|^~\&|APP|FACIL|||20250821143621||ACK|CUEACK_20250821143621|P|2.4
MSA|AE||Failed to queue message

This is some of the Action Codes I've tried:

  • E*Failed to queue message=S
  • E*Failed=S
  • E*"Failed to queue message"=S
  • :E*Failed to queue message=S
  • :?E*Failed to queue message=S

It's not suspending the message however.

What am I doing wrong?

Thank you

Building a robot with IRIS

In this case, a robot is nothing like Gort from the movie “The Day the Earth Stood Still” or any other humanoid robot from science fiction. Nor is this Robot the one-armed automated welder from a real-world automotive assembly line. This Robot is a program that controls another program. You might want this for automated testing or to capture application logic from an application for which you don’t have the source, and the application’s author lacked the kindness or foresight to provide an API for its capabilities.

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together.

1. Working with Dynamic Objects:

Trying to create a new SQL Storage map on existing cache Global in the following format - ^MYGLO("R",rec)=data where the 'data' is built using $zel. e.g. $zel(data,1)="p1", $zel(data,2)="p2" etc... and the ^MYGLO("R",123)=data.

I'm having 2 issues. First, using the SQL Storage map wizard, I cannot figure out how to convey data in $zel format in the "Delimiter" field.

Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.

In the Caché database, when calculating the total count based on the unique identifier of a record, the quantity is over 1.2 million. After removing duplicates based on the unique identifier and then calculating the total count, the quantity is over 400,000. When grouping by the unique identifier, it can be observed that the count for this identifier is not one. However, when performing a conditional query based on the identifier, only one record can be retrieved. Why is this the case?

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

I have a personal copy of Cache which I use to help me with certain things. The instance resides on my Windows desktop. The apps I use a web enabled. It would be great if I could access my apps via web browser from my laptop without having to keep a copy of Cache on my laptop. It would make it difficult to keep the databases synced. So, if I restart my Cache instance, then I can use get to my apps by entering the url: http://ipadd:57772/csp/user/myapp.cls.

I am writing a little app where I press a button on a Zen form. It calls a ZenMethod that uses zenPage.launchPopupWindow() to provide me a way to choose a file. I then click on an upload button that calls a csp cache language script file that runs on the server, that grabs the contents of the file and stuffs it into a global. I want it then close and return to the parent window to continue processing the contents of the file.

Working in healthcare IT as a young developer, especially on InterSystems TrakCare, you quickly realize one thing: it’s not just about HL7 messages or backend integrations. A huge part of making TrakCare work smoothly for hospitals comes down to how it’s configured, customized, and supported on the application side.
