New Features and Functionality

Cluster Reconfiguration Notification Protocol

The Cluster Reconfiguration Notification Protocol (CRNP) provides a mechanism for applications to register for, and receive subsequent asynchronous notification of Sun Cluster reconfiguration events. Both data services running on the cluster and applications running outside of the cluster can register for event notification. Notifications include changes in cluster membership, resource groups, and resource state.

Disk-Path Monitoring

Disk-Path Monitoring (DPM) informs system administrators of diskpath failures for both primary and secondary paths. Disk path failure detection mechanism generates an event through the Cluster Event Framework and allows manual intervention.

Application Traffic Striping Over the Sun Cluster Private Network

This feature stripes IP traffic sent to the per-node logical IP addresses across all private interconnects. TCP traffic is striped on a per connection granularity. UDP traffic is striped on a per packet basis. .

Detecting Vulnerable Configurations

The integration of Sun's eRAS knowledge engine with the sccheck(1M), utility greatly increases the power of sccheck to detect “vulnerable” configurations by leveraging many existing eRAS checks. Vulnerability reports are produced fro both individual nodes as well as the cluster.

Role-Based Access Control

This feature enables the use of Role Based Access Control (RBAC) for cluster administration and operation.

Single Node Cluster

This feature extends Sun Cluster functionality to support single-node clusters.

Agent Builder Integrated with Sun ONE Studio

This feature enables developers to use Sun ONE Studio's development environment to create agents.

Centralized Install

This feature enhances scinstall(1M) to install all nodes of a new cluster from a single point of control. Additionally, it provides compatibility with the Solaris Web Start installation tool.

Localized Versions

Localized Sun Cluster components are now available in five languages and can be installed using the Web Start program. For more information, see Sun Cluster 3.1 10/03 Software Installation Guide.

Data Services

For information on data services enhancements, see Sun Cluster 3.1 Data Services 10/03 Release Notes.
