Veritas Cluster Server 4.x for Solaris

You will learn how to use VERITAS Cluster Server to manage applications in high availability environment. After gaining the fundamental skills that are needed to manage a highly available application in an existing cluster, you will deploy VCS in a lab environment to implement a sample cluster design. You learn to:

	Manage existing highly available application services using VERITAS Cluster Server.
	Install VCS and create a cluster.
	Configure service groups and resources.
	Implement and verify failover and failback capability for application, storage, and network services.
	Configure and optimize cluster behavior.
	Protect data in a shared storage environment.
	Configure VCS to manage an Oracle database, an NFS share, and other applications.
	Analyze, troubleshoot, and correct cluster problems.
	Implement four-node clusters.
	Configure service group dependencies and workload management.
	Implement alternative storage and network configurations.
	Perform ongoing maintenance.
