InterSystems has corrected a defect that can result in data integrity problems in environments that use InterSystems mirroring in conjunction with parallel dejournaling. This problem exists for currently released Caché and Ensemble versions beginning with 2017.2 and for InterSystems IRIS Data Platform version 2018.1.
September 24, 2018 – Advisory: VMWare vSAN and Data Integrity
Clients running vSAN 6.6 or later should review a very important article that VMware published on September 21, 2018. The article describes the possibility of file system and database corruption, which can lead to outages and possible data loss, and we believe that some of our clients have encountered this issue. Therefore, we encourage you to act on this as soon as possible.
Starting with 2017.1, InterSystems has moved macOS from being a server platform to a development platform. 2017.1 will only support macOS 10.12 and will no longer be available as dmg kits.
Verification of macOS 10.12 has not been completed at this time and Field Test kits for this platform are not yet available.
As previously announced, 2017.1 on VSI OpenVMS 8.4-1H1 is the final major version of Caché and Ensemble. 2017.1 will not be available for VSI OpenVMS versions beyond 8.4-1H1.
June 26, 2017 – Alert: Data Corruption with Mixed Endian Mirror Shadowing
InterSystems has corrected a defect that may result in corruption of Unicode data on a shadow system whose source is an async mirror member.
This defect affects all currently released Caché, Ensemble, and HealthShare distributions beginning with version 2012.2.0. All platforms and operating systems are affected.
The last version of Caché, Ensemble released for VSI OpenVMS is 2017.1. Unlike HP OpenVMS (Alpha and Itanium), VSI OpenVMS on Itanium continues to be supported. This means that critical corrections or changes required to support customer’s hardware purchases will all be based on 2017.1 or earlier versions.
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.
At the end of this year support for OpenSSL 1.0.1 will end. InterSystems has started the process to move to OpenSSL 1.0.2 and use the 1/28/2016 release (1.0.2f) for verification and product inclusion. I will update this post once InterSystems decided which versions will receive support for OpenSSL 1.0.2.
