June 16, 2021 - Advisory: Discontinued Technologies and Features
Note: A previous version of this advisory listed Caché Server Pages as a deprecated technology. Caché Server Pages is not deprecated and is fully supported.
InterSystems has identified an issue with product distributions containing Certificate Authority certificates that expire at the end of 2020. This issue does not affect system operation or system security in any way, although it does generate alerts about expiring certificates in the cconsole.log or messages.log files.
InterSystems has corrected a defect that may cause Windows Telnet processes that are secured using SSL/TLS to hang indefinitely; this may then cause an instance to become unresponsive. This defect is present only on Windows platforms.
InterSystems has corrected a defect that can cause a build-up of orphaned processes consuming system resources. In extreme cases, this can cause a system to become unresponsive.
InterSystems has corrected a defect that can cause FHIR searches to return incomplete results. The defect manifests because a FHIR update interaction deletes an incorrect resource from the search index.
InterSystems has corrected two defects that affect online backup of very large databases. Backups taken via external methods, such as snapshots or direct file copies, are not affected. These defects exist in all released versions of all InterSystems products.
InterSystems has corrected two defects that, in rare circumstances, can result in data integrity corruption after running global compaction, database compaction, or database defragmentation. InterSystems recommends avoiding these utilities until after applying the corrections listed below.
Starting in March 2020, Microsoft plans to release a series of security updates that will cause Windows Active Directory (AD) servers to reject unencrypted simple binds.
InterSystems has corrected a defect that can result in skipping a transaction rollback. This can only occur after activation or addition of a mirrored database on a primary mirror member.
InterSystems has corrected several critical defects that can result in data integrity issues. These defects were identified and corrected within a short time, so InterSystems has simplified the upgrade process by consolidating them into a single package. The effects of encountering these defects may not always be visible.
InterSystems has corrected a defect in applications that use Unicode character 223 (ß). This defect can result in incomplete query results, class compilation errors, and removal of custom SQL privileges.
This problem occurs on systems that are running or have previously run on:
Caché and Ensemble 2018.1.0, 2018.1.1, and 2018.1.2
HealthShare Health Connect (HSAP) 15.032 on Core versions 2018.1.0, 2018.1.1, and 2018.1.2
HealthShare Health Connect 2019.1
InterSystems IRIS data platform – all currently released versions
InterSystems IRIS for Health – all currently released versions
The defect is triggered by data and component names containing Unicode character 223 (ß). In the versions listed above, an uppercase conversion incorrectly maps that character to Unicode character 7838 (ẞ). Applications perform this uppercase conversion using features such as $ZCONVERT and %SQLUPPER.
Problems can occur when accessing data or classes created or modified on a product with a different uppercase conversion than the one currently in use.
