InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.
Whether you are accessing DeepSee for the first time ever or you are configuring DeepSee on a new instance, there are two common issues that are encountered after clicking on the “DeepSee” option in the System Management Portal.
Issue #1: Architect/Analyzer is grayed out!
Issue #2: DeepSee must be enabled before use.
There are two common causes for this problem.
The first common cause is that the license does not have these DeepSee options enabled.
A short post for now to answer a question that came up. In post two of this series I included graphs of performance data extracted from pButtons. I was asked off-line if there is a quicker way than cut/paste to extract metrics for mgstat etc from a pButtons .html file for easy charting in Excel.
See: - Part 2 - Looking at the metrics we collected
pButtons compiles data it collects into a single html file to make it easier to send to WRC and review the collated data.
I saw someone recently refer to ECP as magic. It certainly seems so, and there is a lot of very clever engineering to make it work. But the following sequence of diagrams is a simple view of how data is retrieved and used across a distributed architecture.

Date range queries going too slow for you? SQL Performance got you down? I have ANOTHER weird trick that SQL Developers don't want you to know!*

This article provides a reference architecture as a sample for providing robust performing and highly available applications based on InterSystems Technologies that are applicable to Caché, Ensemble, HealthShare, TrakCare, and associated embedded technologies such as DeepSee, iKnow, Zen and Zen Mojo.
Azure has two different deployment models for creating and working with resources: Azure Classic and Azure Resource Manager. The information detailed in this article is based on the Azure Resource Manager model (ARM).
Post updated in August 2025 to include links to IRIS.
I have seen customer problems where the use of a virus scanner running over Caché or IRIS databases was causing intermittent application slowdowns and bad user response times.
This is a surprisingly common problem, so this short post is just a reminder to exclude key Caché and IRIS components from your virus scanning.
Generally, virus scanning must exclude the CACHE.DAT or IRIS.DAT database files and the InterSystems binaries. If an anti-virus is scanning *.DAT files and other InterSystems files such as journals and binaries, then system
Hi!
Want to share with you code snippet of try catch block I usually use in methods which should return %Status.
{
try {
$$$TOE(sc,StatusMethod())
}
catch e {
set sc=e.AsStatus()
do e.Log()
}
Quit sc
}
Here $$$TOE is a short form of $$$TROWONERROR macro.
Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.
In case of sc contains error execution will be routed to try catch block. You can wrap any Status methods calls in your code if you need to catch the errors coming from them.
In try catch block I
