Veritas Cluster Server Administration VRT-202

The VERITAS Cluster Server course is designed for the IT professional tasked with installing, configuring, and maintaining VCS clusters. This five-day, instructor-led, hands-on class covers how to use VERITAS Cluster Server to manage applications in a high availability environment. After gaining the fundamental skills that are needed to manage a highly available application in a cluster, you will deploy VCS in a lab environment to implement a sample cluster design.

Co se v kurzu naučíte:

• 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 network configurations
