Oracle Solaris Cluster 4.2 is out!

Oracle Solaris Cluster 4.2 has been released today, together with Oracle Solaris 11.2, Oracle’s flagship operating system! This latest version offers maximized availability and orchestrated disaster recovery for enterprise applications, leveraging Oracle Solaris 11.2's latest virtualization and software life-cycle technologies.

It delivers:

  • Extreme availability for virtualized workloads and applications

    Oracle Solaris Cluster 4.2 adds support for Oracle Solaris Kernel Zones with an updated failover zone agent which provides monitoring, automatic restart and failover as well as warm migration of kernel zones. It combines resiliency with the flexibility offered by kernel zones to have independent kernel versions and patch levels.

    Two new agents, for Oracle JD Edwards EnterpriseOne and GoldenGate have been added to the portfolio, offering application specific monitoring and recovery policies, providing increased application up-time to these Oracle solutions.

    This new release also offers support for Oracle 12.1 RAC database options such as Oracle Multitenant, service agents, policy managed database as well as new versions for a set of applications such as Oracle Business Intelligence, Siebel, ...

  • Fast and reliable disaster recovery for multi-tiered services

    The new orchestrated disaster recovery manages the automated and synchronized recovery of multiple applications and their respective replication solution across multiple sites, offering significant gains in terms of reliability, speed of recovery and reduced risk.

  • Agile deployments with Oracle Solaris lifecycle management

    The new Oracle Solaris Unified Archives format can now be used with Oracle Solaris Cluster to recover or clone easily and rapidly either physical clusters or virtual clusters. Also with the support for the new secure Automated Installer, cluster deployments can leverage Oracle Solaris end-to-end secure provisioning.

  • Simplified administration with new GUI

    The new browser based graphical user interface offers a single point access to status, configuration and management capabilities. Its topology, tree and table views offer easy navigation inside cluster instances both in local or multi-cluster configurations facilitating operations, monitoring, and diagnostics.

  • Flexible and easy integration for custom applications with the new GDSv2

    Agent (or data service) development allows you to deploy your application within the Oracle Solaris Cluster infrastructure. The Generic Data Service (GDS) has been designed and developed by Oracle Solaris Cluster engineering to reduce the complexity associated with data service development. GDS v2 further increases flexibility, ease of use and security of this already trusted and robust development tool.

  • Designed and tested together with Oracle hardware, infrastructure software and applications to deliver best time to value

    Oracle Solaris Cluster is engineered from the ground up to support the stringent requirements of a multi-tier mission critical environment. It is thoroughly tested with the Oracle servers, storage and networking component and integrated with Oracle Solaris. And last but not least it delivers the application high availability framework for Oracle Optimized Solutions and Oracle SuperCluster, Oracle's premier general purpose engineered system.

If you are interested to know more stay tuned: we have planned a series of posts going into much more details. In the mean time download the software and the documentation and try it out !

Looking forward to your comments,
Eve and the Oracle Solaris Cluster engineering team

Configuring HA for Oracle WebLogic Server Managed Servers by Using the clsetup Wizard

This post describes the steps to use the clsetup wizard to configure an Oracle WebLogic Server Managed Servers instance as a highly available failover data service with Oracle Solaris Cluster software.

HA Prerequisites

  • The logical host resource to be used by the data service is configured.

  • The administration server instance of Oracle WebLogic Server software is running. This is to avoid the delay during discovery of the managed servers, which might take 10 minutes or longer.

  • The common agent container (cacao) service is running on the nodes on which Oracle WebLogic Server software will be configured.

Application Prerequisites

  • The file is in the $DOMAIN_DIR/servers/<server-name>/security folder.

  • The Managed Server to be configured is created.

Points to Note

While using the clsetup wizard:

  • Type a question mark (?) to access the help.

  • Type a left angle bracket (<) or a right angle bracket (>) to move backward or forward, respectively.

  • Each input provided is validated by the wizard.


From a command prompt, type clsetup to start the utility. From the clsetup menu, select "Data Services". In the next menu, select “Oracle WebLogic Server”.

The following table is an overview of the steps that the clsetup wizard performs to configure the data service.





Select Oracle WebLogic Server Location

Select "Global Cluster" or "Zone Cluster". If you select “Zone Cluster”, in the next menu select the zone cluster in which to configure the data service.


WebLogic Server Configuration

Lists the available types of configuration. Select “Managed Servers”.


Verify Prerequisites

Make sure all listed prerequisites are met.


Specify Domain Location

Be sure to provide the proper domain location. If you provide the proper domain location and no customized configuration is made in the Oracle WebLogic Server software, the clsetup wizard will auto-discover the parameter values.


Specify WebLogic Home Directory

Either select a directory from the discovered values or specify your own home directory by selecting the option “Specify explicitly”.


Specify WebLogic Managed Server Start Script

Press “RETURN” to accept the discovered value or type your own value.


Specify WebLogic Server Environment File

Press “RETURN” to accept the discovered value or type your own value.


Select Configuration Mode for Managed Servers

Select “Failover”.


Select Managed Server

Select from the displayed list the Managed Server that you want to configure.


Select Logical Hostname for Managed Server <Managed Server Name>

Select the appropriate logicalhost from the list.


Specify Monitoring URI

Specify the URI or leave the field blank. To specify multiple monitoring URIs, separate them by commas. If you specify a URI, it will be validated.


Configure Highly Available Storage Resources

Select the appropriate storage from the list.


Review Panel

Displays the values entered. To edit the information, choose the corresponding number.


Summary Panel

Displays the values you entered. [This panel is read only.]

Configuring the HA for Oracle WebLogic Server service by using the clsetup wizard is easy, effective, and ensures proper configuration of properties for resources and resource groups.

Oracle Solaris Cluster 4.0 and Oracle Solaris 11 Software Supported on Third Party Storage

Oracle Solaris Cluster software can be used with different storage
technologies such as FC, SCSI, iSCSI and NAS on Oracle storage and
third party storage. There is also support for highly available
Oracle Solaris ZFS, POSIX compliant cluster file system, raw disk
access to cluster-wide global devices and volume managers. Oracle
Solaris Cluster software provides the highest levels of data
integrity and availability using innovative fencing and quorum
technologies.  Oracle Solaris Cluster software has a validation tool
called OSCATE (Oracle Solaris Cluster Automated Test Environment)
that is used to verify that the storage under test meets all the
requirements for successful integration with the Oracle Solaris
Cluster product. It has a combination of functional, load tests and
real world fault injection scenarios to ensure end-to-end
availability of the entire stack all the way from applications to

Third party storage partners are diligently working towards becoming
certified with Oracle Solaris Cluster 4.0 and Oracle Solaris 11
software.  Partners now certified are EMC, Hitachi Data Systems,
HP/3PAR, IBM and NEC.  Certification is essential prior to
