Oracle has announced the availability of Oracle Solaris Cluster 4.0, the first release providing extended high availability (HA) and disaster recovery (DR) capabilities for Oracle Solaris 11. Oracle Solaris Cluster works by extending Oracle Solaris to provide the HA and DR infrastructure required for deploying mission critical workloads in private, public and hybrid clouds as well as enterprise data centers. Among the other strong points of the solution are built-in support for cloud implementations and cloud-ready application protection through fine-grained monitoring and policy-based application management, along with restart and failover capabilities.

Gary Combs and Eve Kleinknecht, both principal product managers at Oracle, presented at Oracle Open World on "Best Practices for Mission-Critical Computing on SPARC Servers." Now the 50-slide set from their presentation is available for download and viewing. The presentation concludes that the best High Availability solution for Oracle Solaris (itself the number one enterprise OS) is Oracle Solaris Cluster for its ability to deliver higher service levels for mission critical applications; its ability to provide protection for consolidated, virtualized workloads; and its ability to perform disaster recovery in an elastic, flexible environment.

cluster check is "one of the best kept secrets of Oracle Solaris Cluster," blogs Ed McKnight. He writes that the latest set of enhancements to cluster check focuses on validating clusters during installation and initial configuration, which enables administrators to perform the most important of the Enterprise Installation Services (EIS) checks themselves. A further important change that McKnight points out is in the titling of check results in progress reporting. He adds that there are now some 40 new checks.

Along with his announcement of the release of Oracle Solaris Cluster 3.3.05/11 Update 1 Juergen Schleich blogs that the package version of the Oracle Solaris Cluster 3.3 05/11 Update1 is the same for the core framework and the agents as for Oracle Solaris Cluster 3.3. Therefore, he points out, it's possible to patch up an existing Oracle Solaris Cluster 3.3. On the other hand, he continues, the package version of the Oracle Solaris Cluster Geographic Edition 3.3 05/11 Update1 is NOT the same as Oracle Solaris Cluster Geographic Edition 3.3, although it's possible to upgrade the Geographic Edition 3.3 without interruption of the service. Schleich's blog includes an extensive list of patch revisions for both Solaris 10 10/09 Update8 or higher and for Solaris 10 x86 10/09 Update8 or higher.
