Support for server-based fencing
The Coordination Point Server provides an alternative fencing mechanism that
integrates with the existing VCS I/O fencing module.
The Coordination Point server (CPS) is a software solution running on a remote
system or cluster that provides arbitration functionality by allowing client cluster
nodes to perform the following tasks:
■ Self-register to become a member of an active client cluster with access to the
data drives
■ Check which other nodes are registered as members of this active client cluster
■ Self-unregister from this active client cluster
■ Forcefully unregister other nodes (preempt) as members of this active client
cluster
Multiple client clusters running different operating systems are able to
simultaneously access the CP server. TCP/IP based communication is used between
the CP server and client clusters.
Enhanced sample configuration files
This release of SF Oracle RAC includes a number of sample configuration files
that illustrate various deployment scenarios. Each sample file contains a high-level
description of the deployment scenario. The files are located at
/etc/VRTSvcs/conf/sample_rac/.
Support for load balancing in MultiPrivNIC
The MultiPrivNIC agent supports load-balanced fail over if multiple links are
identified as failover targets. A new attribute UseLoadBalance is introduced to
support load balanced fail over of links. In the event that a preferred link goes
down, the IP address is failed over to a private link on which maximum number
of peer nodes are visible. If multiple links see maximum nodes and if load-balancing
