Solaris support update

Delphix introduces limited Solaris support to the Delphix Continuous Data Engine following its removal in 2026.2. This is a narrow re-introduction intended to provide a supported path forward for the small number of customers who were unable to migrate off Solaris within the original deprecation window outlined in TB133. It is not a full restoration of the prior Solaris support matrix.

Background

Solaris was removed in 2026.2 as part of the Delphix Engine's migration from Java 8 to Java 17, since no official OpenJDK 17 distribution is available for Solaris. The 2026.3 re-introduction is enabled by a community-maintained OpenJDK 17 build for Solaris that has been validated against Delphix Engine requirements.

Supported configuration

Component	Supported
Operating System	Solaris 11.4 (SPARC only)
Database	Oracle 19c
Storage Protocol	NFSv4 with dNFS
Java Runtime	Community-maintained OpenJDK 17 build for Solaris

Explicitly not supported

The following Oracle configurations on Solaris are not supported in this re-introduction, regardless of whether they were supported prior to 2026.2:

• Multi-tenant architecture (CDB / PDB)

• Real Application Clusters (RAC)

• Transparent Data Encryption (TDE)

• Solaris on x86

• Any Oracle version other than 19c

Customer Guidance

Customers electing to run Delphix Engine 2026.3 on Solaris should be aware that this configuration depends on a community-maintained OpenJDK 17 build rather than an officially supported distribution from Oracle, a major OS vendor, or a commercial Java runtime provider. While Delphix has validated this build against the supported configuration described in the support matrix above, the runtime itself is produced and maintained by a third-party open-source community, and using it carries risks that customers should evaluate before deployment.

Specifically, customers should be aware of the following: security patches and CVE fixes for the Java runtime are released on the community's own schedule, which may lag behind the timelines published by commercial JDK vendors and may, in some cases, not be backported at all. There is no commercial support contract, SLA, or warranty available for the runtime itself, meaning that any defect, performance issue, or vulnerability discovered in the JDK must be addressed either through community channels or by waiting for a future community release. The long-term availability of the build is also not guaranteed; if the maintaining community discontinues the project, future Delphix releases may be unable to continue Solaris support, and customers may be required to migrate on short notice. In addition, certain Java-level features, optimizations, or platform integrations available in commercial JDK distributions may not be present, fully tested, or performance-tuned in the community build.

Customers should also recognize that, while Delphix will make commercially reasonable efforts to support the validated configuration, issues isolated to the Java runtime itself may fall outside Delphix's ability to remediate directly and may require coordination with the upstream community. For these reasons, this configuration is intended as a transitional path for customers who cannot migrate off Solaris within the original deprecation window, and not as a recommended long-term platform. Customers are strongly encouraged to maintain an active migration plan to a fully supported operating system and to engage their Customer Success Manager prior to deployment to review these risks in the context of their specific environment.
