HealthShare Unified Care Record Fundamentals - Virtual January 29-February 2, 2024

Hey Developers,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in May 2021:

Introduction

Businesses often use in-memory databases or key-value stores (caching layers) when applications require extremely high performance. However, in-memory databases incur a high total cost of ownership and have hard scalability limits, incurring reliability problems and restart delays when memory limits are exceeded. In-memory key-value stores share these limitations and introduce architectural complexity and network latency as well.

This article explains why InterSystems IRIS™ data platform is a superior alternative to in-memory databases and key-value stores for highperformance SQL and NoSQL applications.

Taking Performance and Efficiency to the Next Level

InterSystems IRIS is the only persistent database that can match or beat the performance of in-memory databases and caching layers for concurrent data ingestion and analytics processing. It can process incoming transactions, persist the data to disk, and index it for analytics in under one microsecond on commercially available hardware without introducing network latency.

The superior ingest performance of InterSystems IRIS results in part from its multi-dimensional data engine, which allows efficient and compact storage in a rich data structure. Using an efficient, multi-dimensional data model with sparse storage techniques instead of two-dimensional tables, random data access and updates are accomplished with very high performance, fewer resources and less disk capacity. It also provides in-memory, in-process APIs in addition to traditional TCP/IP access APIs to optimize ingest performance.

I need to connect to a SFTP server and I seem to connect and timeout have tested the connection using File-zilla and the connection was successful but the problem is when I try to connect using the FTP in bound adapter service I get the following errors.

ERROR <Ens>ErrOutConnectExpired: FTP Connect timeout period (120) expired for ***************.com:990/******/SSL='********* + ERROR <Ens>ErrFTPConnectFailed: FTP: Failed to connect to server ***************.com:990/******/SSL='********* (msg='Timeout waiting for response',code=529)

Help!

I want to get rid of this account but there seems to be no way to do this by myself. Whom can I write to, to have my account deleted? Thank you in advance...

We are building a data transformation from HL7 to custom XML. We've got an XML schema, and are using virtual documents (EnsLib.EDI.XML.Document).

We can:

I am excited to share that the Learning Services team has recently added new content to our InterSystems Reports Learning Path. These latest videos, created by our partner, insightsoftware, provide instruction for developing reports with InterSystems Report Designer.

In these three short videos, you’ll learn how to:

Hi

We have a use case whereby very large HL7 MDM messages, which contain many OBX segments, need to be processed by a custom business process. Part of the process is to iterate over each OBX segment and set a value in the same field for each segment.

I recently set up InterSystems in the Azure cloud environment. So far, no issues. Recently, I was tasked with uploading the IRIS.dat file (FoIA VISTA) into the instance. I was guided by my teammates to do the following: System Administration > Configuration > Local Databases. The problem is that I need to transfer the .dat file to the instance, because, as it is running on a local machine, it cannot retrieve files from my local drive. Is there a reliable solution, such as a transfer method or way of using the Web Gateway endpoint, one can provide to assist?

Online document says: TUNE TABLE updates the SQL table definition (and therefore requires privileges to alter the table definition). Commonly, TUNE TABLE also updates the corresponding persistent class definition. This allows the gathered statistics to be used by the query optimizer without requiring a class compilation.

Just a few days left to tell us how you like to learn!

Want a say in how we structure our learning content? Take this brief survey by March 31, and we’ll use your feedback to improve your learning experience.

• Do you like to watch how-to videos?
• Hate videos, but love the doc?
• Don't read the doc, but want more in-person classroom learning?

Let us know in this 3-min survey!

Hey developers,

We want to hear from you! Give us your feedback on the past InterSystems Developer Tools Contest! Please answer some questions to help us improve our contests.

The first part of this article provides all the background information. It also includes links to the DATATYPE_SAMPLE database, which you can use to follow along with the examples.

In that section, we explored an error type ("Access Failure") that is easy to detect, as it immediately triggers a clear error message when attempting to read the data via the database driver.

Securing IRIS Integrations with Mutual TLS (mTLS): A Practical Guide

In today’s enterprise environments, secure communication between systems is not optional—it’s essential. Whether you're integrating InterSystems IRIS with cloud APIs, internal microservices, or third-party platforms, Mutual TLS (mTLS) offers a powerful way to ensure both ends of the connection are authenticated and encrypted.

This post walks through how to configure IRIS for mTLS and how to validate your certificates to avoid common pitfalls.
