General
What is Solaris Cluster software?
A:
Previously known as Sun Cluster, the Solaris Cluster framework
extends high availability features of Solaris - it includes Solaris
Cluster, Solaris Cluster Geographic Edition, developer tools and
support for commercial and open-source applications through Solaris
Cluster agents. The integrated software provides high
availability and disaster recovery for local, campus, metropolitan and
worldwide clusters.
Q:
What is the difference between Sun Cluster and Solaris Cluster?
A:
There is no difference. The name of Sun Cluster has been changed
recently to Solaris Cluster.
Q:
How does Solaris Cluster work?
A:
By tightly coupling Sun's servers, storage and networking solutions,
Solaris Cluster provides the maximum level of service availability and
performance for a cluster system.
The servers (nodes) in a cluster communicate through private interconnects. These interconnects carry important cluster information (data as well as a cluster "heartbeat"). This heartbeat lets the servers in the cluster monitor the health of the other servers within the cluster, ensuring that each server is "alive". If one of the servers goes offline and its heartbeat disappears, the rest of the devices in the cluster isolate the server and "fail-over" any application or data from the failing node to another node. This fail-over process is quick and transparent to users of the application. By exploiting the redundancy in the cluster, Solaris Cluster ensures the highest levels of availability. A typical Solaris Cluster configuration has the following components: Hardware Components:
Q:
What is Solaris Cluster Geographic Edition?
A:
Solaris Cluster Geographic Edition software enables a multi-site
disaster recovery solution that manages the availability of
application services and data across geographically dispersed
Solaris Clusters. In the event that a primary cluster goes down, Solaris
Cluster Geographic Edition enables sysadmins to start up automatically
business applications with replicated data on the secondary Solaris
Cluster.
Q:
What is a Solaris Cluster Agent?
A:
A Solaris Cluster agent is a k-sh script, a C-program, or a binary
that manages the availability of an application. The agent starts,
stops, monitors the health of the application, and takes corrective
action to regain application availability upon failure. Applications
do not need to be modified to benefit from the enhanced availability offered
by the Solaris Cluster agent.
The Solaris Cluster development team, as well as other third-party software vendors, have created tailored agents for popular applications such as Java Enterprise System applications, Oracle, Siebel, SAP, Sybase, MySQL, Apache and many others. If your application does not have an available tailored agent, you can create your own using the Solaris Cluster Agent Builder (included with the Solaris Cluster software). This agent builder has an easy to use, "wizard" graphical user interface which leads the user through the steps of creating an agent. After the user completes the agent build process, a ready-to-use agent is available for immediate use. (The whole process takes only a few minutes from start to finish).

Q:
What is the Sun Java Availability Suite?
A:
Sun Java Availability Suite - is a subset of Sun Java Enterprise System (JES).
Java Availability Suite delivers a subscription-based license for Solaris Cluster components.
Q:
What is the Solaris Cluster Advanced Edition for Oracle RAC software about?
A:
Solaris Cluster Advanced Edition for Oracle RAC is an enhanced software offering that delivers unmatched availability, performance and manageability at the lowest total cost of ownership for Oracle RAC deployments on Solaris 10.
This end-to-end Sun stack consisting of Sun StorageTek QFS software, Solaris Cluster RAC agent and Solaris Volume Manager extensions provides unprecedented scalability and the most cost effective deployment platform for commercial grid environments that use Oracle RAC, a component of the Oracle 9i, 10g, 11g database products.

A:
Java System Applications:
What is the difference between Solaris Cluster and Open HA Cluster?
A:
Open HA Cluster is an open source code base, along with build tools necessary to develop, build, and use the code. It's a mechanism to communicate and share
information about Solaris Cluster and Open HA Cluster, and provides
a community-based collaboration platform for addind new cutting-edge features to the code base.
The main difference between Open HA Cluster and Solaris Cluster is that Sun offers no formal support for the Open HA Cluster product in either source or binary form. The Solaris Cluster product is branded, tested, maintained, and supported as a Sun product. Future releases of Solaris Cluster could be built from the Open HA Cluster source code, but will be supported in the same manner as current versions of the Solaris Cluster products. However, the intent is to release as much of the existing source code as possible through Open HA Cluster and to direct future development through the HA Cluster community.
Q:
Which parts of Solaris Cluster have been open-sourced?
A:
Sun's current contributions are application modules, or agents, which enable open source or commercially available applications to become highly available in a clustered environment; and Solaris Cluster Geographic Edition.
The complete list of agents is available at http://opensolaris.org/os/community/ha-clusters/ohac/Documentation/Agents/open-agents/ Solaris Cluster core has not yet been open-sourced. On the test side, the test tools (CTI for TET framework) and the specific agent test suites (DATS - Data Services Automated Test Suite ) have been open-sourced.
Q:
Why release Solaris Cluster as open source?
A:
Sun believes very strongly in the value of open source, and is the largest contributor to open source software. Sun is committed to providing open source for most of its software products. In the two years since Sun first opened the Solaris source code, the OpenSolaris project community has grown worldwide. Sun is releasing Open High Availability Cluster in response to interest and feedback from the OpenSolaris community.
Open source provides a number of benefits to the community:
Q:
What is the roadmap for Open HA Cluster?
A:
The Open HA Cluster code is being made available in three phases, beginning in June 2007 and continuing over 12 months. In the first phase, Sun delivered code for most of the high availability agents offered with the Solaris Cluster product.
Sun also made available the source code for the Solaris Cluster Automated Test Environment (SCATE) and agent-related documentation to assist with testing new agents. In the second phase (December 2007) Sun has contributed the code for the recently released Solaris Cluster Geographic Edition - software that enables multi-site disaster recovery by managing the availability of application services and data across geographically dispersed clusters.
Later, Sun will release the code for the core Solaris Cluster infrastructure, again with SCATE infrastructure tests and documentation.
Q:
What license is used for Open HA Cluster?
A:
The Open HA Cluster code is released under the Common Development and Distribution License (CDDL). Information about this license can be found at
https://opensolaris.org/os/licensing/opensolaris_license and at our website.
The CDDL is an OSI-approved open source license that is based on the Mozilla Public License (MPL) but adds additional benefits like extending the use of any covered patents to those that use the code and offering a degree of protection against patent litigation. Further, the CDDL is a file-based license, which ensures that any code released under the CDDL will remain open but does allow it to interact with code under other licenses (even closed source licenses). | |
