InterSystems has corrected a defect that impacts the use of X.509 private keys stored in Caché, Ensemble, and Health Connect, but only in 2018.1.1, on any platform.
February 25, 2016 – Alert: Incorrect SQL Results
InterSystems has corrected a defect that can cause incorrect results for certain SQL INSERT, UPDATE, and DELETE statements.
This defect is present only in Caché and Ensemble 2015.2 and HealthShare distributions based on them. The problem affects all platforms.
Incorrect results occur only when two or more of these statements are nested within each other.
The example below demonstrates one possible way for this problem to happen:
InterSystems has corrected a defect that may result in missing updates when utilizing Caché online backup.
This defect is present in all Caché and Ensemble versions 2015.1.x, 2015.2.x and 2016.1.x, and all HealthShare distributions based on those versions. It affects all platforms and operating systems except backups of OpenVMS cluster databases.
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.
July 27, 2017 – Alert: Linux Defects Can Corrupt Mirror Copies of Journal Files
InterSystems has encountered defects in Linux which can corrupt copies of journal files that are generated on a mirror backup or async member; this occurs only in certain specific configurations. The original mirror journal file created on the primary member is not affected.
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 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 a defect with Mirroring that can impact data integrity
The defect is present in all released versions Caché, Ensemble, and HealthShare beginning with 2015.2.0. It is present for all platforms and affects both failover and asynchronous mirroring configurations.
InterSystems has encountered a defect that causes some upgrades of HealthShare® Health Connect to fail. This only affects instances that are not licensed for the use of FHIR® and that have interoperability-enabled namespaces. Under these conditions, the upgrade fails with an <HSFHIRErr> error.
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 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.
That alert indicated that the database defragmentation utility in 2014.1 and higher, on all platforms except OpenVMS, could cause database degradation and the correction JO2871 is available to clients upon request and would be included in future releases. The correction was included in 2015.1.3, 2015.2.2 and 2016.1.
InterSystems has corrected a defect that can lead to missing resource data in FHIR search results.
This problem exists for:
HealthShare Unified Care Record 2020.1.0 b7015
This defect occurs due to an incorrect resource being deleted from the search index. Subsequent FHIR Resource requests against the FHIR Repository may return incomplete results due to that missing index. Any type of FHIR resource data can be lost, and depending on when the defect occurs, the same FHIR request could return different result sets.
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.
