Known Issues and Notes

This topic describes known issues in InterSystems IRIS® 2024.1.

Unable to Open Documentation from the Launcher

If you are using a fresh installation of 2024.1, are upgrading from 2023.2 or later, or are using Microsoft IIS as your web server, you cannot open Documentation through the cube by default. To fix this issue, see the documentation for how to manually redirect documentation links with Microsoft IIS.

Clients Incompatible with 2024.1

The Persister 1.0.0 and .NET XEP 2.1.0 clients included in InterSystems IRIS 2024.1 are not compatible with the released version.

InterSystems is working on packaging correct versions of these pieces of software in a later release. If you need assistance with the current release, please contact the WRC.

Regression in NULL-Handling SQL Functions

InterSystems has identified a regression in vectorized, bulk execution of null-handling SQL functions, like IFNULL and NULLIF, which can lead to wrong results. This change only affects 2024.1 and will be fixed in the next release.

AmazonCloudWatchLogs Classes are Deprecated

Two classes, EnsLib.AmazonCloudWatchLogs.BusinessOperationOpens in a new tab and EnsLib.AmazonCloudWatchLogs.OutboundAdapterOpens in a new tab, are discontinued and will be removed in future releases.

Caché and Ensemble Migration to InterSystems IRIS on Microsoft Windows

InterSystems has identified an issue with migrations from Caché and Ensemble to InterSystems IRIS 2023.2 or later. This issue affects instances on Microsoft Windows that use the private web server. (If an instance is running either IIS or another supported web server, then this issue is not relevant.)

During the migration process, the private web server is removed; as a result of this, HTTP connections are not available to the instance after upgrading.

To avoid this issue:

  1. Enable IIS prior to starting the migration. During the migration, the InterSystems IRIS installer detects the presence of the IIS web server and offers to automatically configure it for HTTP connections.

  2. When prompted, choose Yes, to use autoconfiguration.

Alternatively, you can migrate to InterSystems IRIS 2023.1 first and then upgrade to an instance of 2023.2 or a later version. 

InterSystems is working on a correction for InterSystems IRIS 2024.2 and later. If you need further assistance, please contact the WRC for further information.
