Optimizing Performance of Apache Web Server and Web Gateway

By Patrick Jamieson, M.D., Product Technical Manager, InterSystems IRIS for Health

Working on wrapping an IRIS Cache ObjectScript method that runs for a few seconds. Trying to get UI updates to show BEFORE the method runs in an async/await function. But it seems to be running synchronously rather than asynchronously . So my question is does IRIS/ObjectScript CSP pages support futures with JavaScript or does it run all synchronously.

Are you familiar with SQL databases, but not familiar with IRIS? Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar. I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew. However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better. With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc. I hope I can make things clearer and simpler for you and save you some time getting started.

Test Objectives

InterSystems has been testing Vector Search since it was announced as an “experimental feature” in IRIS 2024.1. The first test cycle was aimed at identifying algorithmic inefficiencies and performance constraints during the Development/QD cycle. The next test cycle used simple vector searches for single threaded performance analysis to model reliable, scalable and performant behaviour at production database scale in IRIS, and performed a series of comparative tests of key IRIS vector search features against PostgreSQL/pgvector. The current test cycle models the expected behaviour of real-world customer deployments using complex queries that span multiple indices (vector and non-vector) and run in up to 1000 concurrent threads. These tests will be run against IRIS, PostgreSQL/pgvector, and ElasticSearch

Dear InterSystems-Maintainer Team,

I am currently conducting a comparative evaluation of FHIR clients as part of my
bachelor thesis in health informatics. One of my evaluation criteria is the response
time to support inquiries.

Therefore, I would like to kindly ask the following question as part of my analysis:
How can I read and write custom FHIR extensions using your client library?

If available, could you point me to any documentation or examples?

Many thanks for your time and support!

Hi Guys,

I've my users set in Security->Users in SMP, but I get the below error when trying to long in my application, any clues what this error means?

"0 "_$lb($lb(864,,,,,,,,,$lb(,"US-SERENITY",$lb("e^UsersCSPLogin+87^%SYS.SECURITY^1","e^CSPLogin+103^%SYS.cspServer^1","e^CSPDispatch+909^%SYS.cspServer^1","d^CSPDispatch+907^%SYS.cspServer^1","d^ProcessRequest+1^%CSP.Session.1^1","d^Request+692^%SYS.cspServer2^1","d^Request+25^%SYS.cspServer2^1","d^ProcessRequest+1^%CSP.Request.1^1","d^css+15^%SYS.cspServer2^1","d^Server+64^%SYS.SERVER^2","d^^^0"))))

I am trying to catch an exception and write it to the Application Error Log, but cant find any details on how to do this in IRIS health.

This article is a continuation of the IRIS JSON project and features additional methods and insights.

Let's continue with the instance methods

⏯️ Closing the Scientific Knowledge Gap with AI

For venture capitalists (VCs), evaluating research can be challenging. While researchers typically possess years of training and deep expertise in their field, the VCs tasked with assessing their work often lack domain-specific knowledge. This can lead to incomplete understanding of scientific data and an inability to direct organizational initiatives. To solve this problem, we have designed a solution that empowers VCs with AI-driven due diligence: ResearchExplorer. ResearchExplorer is powered by InterSystems IRIS and GPT-4o to help analyze private biomedical research alongside public sources like PubMed using Retrieval-Augmented Generation (RAG). Users submit natural language queries, and the system returns structured insights, head-to-head research comparisons, and AI-generated summaries. This allows users to bridge expertise gaps while securely protecting proprietary data.

I am trying to create users who only have `%SQL` Role for the INSTANCE. But I am unable to find any documentation on the ` Security.Users` class.

See:

Until now i used $ZF(-1), in older Caché versión, now I try to use $ZF(-100), i do:

REST>w $ZV
Cache for Windows (x86-64) 2018.1.4 (Build 505_1) Thu May 28 2020 10:12:49 EDT
REST>s a=$zf(-100,"/SHELL","dir")
 
S a=$ZF(-100,"/SHELL","dir")
^
<NOTOPEN>

What is wrong?

Thanks in advance
