Solaris Cluster 3.2 11/09 is now available

Solaris Cluster is a multi-system, multi-site high availability and disaster recovery solution that manages the availability of applications services and data across local, regional and geographically dispersed data centers. The Solaris Cluster environment extends the Solaris Operating System into a cluster operating system.

If you are following the Solaris Cluster product and features, you would have noticed extreme innovation by Sun in the high availability and disaster recovery space since the time we released our first HA product many years ago. For well over a decade, Solaris Cluster has been a market leader for providing business continuity and disaster recovery solutions to all mission critical business applications, spanning all the major industry segments.

Continuing with our tradition of innovation, we are pleased to announce another release - "Solaris Cluster 3.2 11/09" - an update to the Solaris Cluster 3.2 product.

This new release brings more features for high availability, virtualization, disaster recovery, flexibility, diagnosibility, and ease of use. We are extending support for virtualization with more options for Solaris Containers Clusters (zone clusters), failover Solaris Containers, and LDoms.  This release provides more file system and volume management choices. We have added new replication solutions for disaster recovery deployments, in addition to improving scalable services support. This release also brings support for the latest versions of many third-party software applications.

The following is a list of some of the new features in this update release:

- New deployment options for Oracle DB, RAC, and applications

  • Solaris Containers cluster support for more Oracle solutions:
    • Oracle E-Business Suite
    • Siebel CRM 8
    • Single-instance Oracle database
  • Support for Oracle Automated Storage Management (ASM) with single-instance Oracle database
  • Support of Reliable Data Sockets over Infiniband for RAC
- Infrastructure features
  • Standalone QFS 4.6 & later in failover Solaris Containers
  • Upgrade on attach for failover Solaris Containers
  • Solaris Volume Manager three-mediator support in Campus Cluster deployments
  • Hitachi Universal Replicator support in Campus Cluster deployments
  • Support for 1TB disks as a quorum devices
- Scalable services features
  • Outgoing connection support for scalable services
  • IPsec support for Scalable Services traffic
  • SCTP support for Scalable services
  • Managed failover of IPsec session & key information
  • Round-robin load balancing
- Geographic Edition
  • Hitachi Universal Replicator support
  • Script-based plugin replication module
  • MySQL replication
- Supported applications and agent features
  • New agent: HA Agent for LDoms guest domains
  • New supported application version: SWIFTAlliance Access & Gateway 6.3
Check here for additional details about the features listed above. Solaris Cluster 3.2 11/09 is supported on Solaris 10 5/09 and 10/09 . Refer to the release notes to get a list of minimum patches required to run this update. The release notes also has links to the product documentation for all the features listed above.

Solaris Cluster: Presentations and Demonstrations at Oracle Open World 2009

If you couldn't make it to Oracle Open World in San Francisco (12th - 15th October) I've put together a quick summary of the presentations and demonstrations that my colleagues and I delivered.

The Solaris Cluster group was given two speaking sessions for the conference:

  1.  "Bulletproof Your Oracle E-Business Suite Deployment with Solaris Cluster" - Neil Garthwaite and Pedro Lay
  2. "Delivering High Availability to Oracle Applications with Solaris Cluster" - Dr Ellard Roush and Tim Read

Neil and Pedro's presentation explained how you could combine Solaris Cluster and Sun Cluster Geographic Edition to create a high availability Oracle's E-Business Suite implementation that also has disaster recovery protection.

The underlying 10g RAC database runs in the global zone and is replicated by Oracle Data Guard to a secondary cluster. The application tier comprising concurrent manager and Oracle Process Manager and Notification Server (opnm) managed services (oafm, forms, oacore and http server) runs in a separate, isolated Solaris Containers cluster, also known as a zone cluster. Using the features of Solaris Cluster and Geographic Edition both local failover and disaster recovery can be achieved without the need to re-run autoconfig.

Oracle Open World E-Business suite demonstration configuration

The picture above shows the configuration demonstrated at Oracle Open World with the exception that shared QFS was used in place of ASM. 

The presentation was backed up by a real implementation using two physically separate clusters. During the show we performed numerous demonstrations. These included local failovers, caused by forcing zone or process failures, and full site switchovers to test the disaster recovery plan. Whereas local failover took only a matter of a few seconds, the site switchover took around 15 minutes to complete, albeit on a somewhat untuned system. On the final day we initiated a full disaster scenario by powering off both of the primary cluster nodes. The takeover of the primary site completed successfully in around 10 minutes. And just to re-iterate, at no point did we need to re-run autoconfig, whether we performed a failover, switchover or site takeover.

Throughout these demonstrations we used Load-Runner to place a background load on the system and give an indication of interactive performance.

Keep an eye out for videos of this setup on the Sun Learning Exchange.

The second presentation given by Ellard and me came in two parts. The first covered how Solaris Containers clusters can be used to consolidate workloads onto a Solaris Cluster with both security isolation and resource constraints. The second part described how a new resource type, or agent, could be written to support an application for which Sun doesn't currently have an offering. The example used in the presentation was Oracle Business Intelligence Enterprise Edition.

Other Solaris Cluster demonstrations at the Sun booth included: HA-ASM, a new agent for managing Oracle ASM, running in a zone cluster and Oracle 11g RAC running over RDS on Infiniband on SPARC servers using Sun's QDR PCIe HCAs and the 36-port switch.

Now if you were at Oracle Open World but didn't sign up to attend our presentations (and look what you've missed!) then you can still access copies of the slides and listen to the recording of the above sessions.

Maybe we'll see you at OOW next year!
