HA0412 : Veritas InfoScale Availability 7.0 for Linux/Unix Administration
Duration : 5 day
ABOUT THIS COURSE
The VeritasInfoScale Availability 7.0 for Linux/Unix:Administration course is designed for the IT professionaltasked with installing, configuring, and maintainingVeritas Cluster Server (VCS) clusters.
This five day, instructor-led, hands-on class covers howto use InfoScale Availability to manage applications in ahigh availability environment. After gaining the fundamental skills that are needed to manage a highly available application in a cluster, you can deploy InfoScale Availability in a lab environment to implement a sample cluster design.
By the completion of this course, you will be able to:
- Describe how clustering is used to implement high availability in the data center environment.
- Describe how clustering is used to implement highavailability in the data center environment.
- Describe VCS and cluster communicationmechanisms.
- Create a cluster, and configure service groups andresources.
- 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.
- Describe I/O fencing operations, and itsimplementation.
- Configure VCS to manage an Oracle database andother applications.
- Configure a global cluster environment, includingremote clusters, global heartbeats, and globalservice groups.
- Configure notification and failover behavior in aglobal cluster.
WHO SHOULD ATTEND
This course is for Linux/Unix system administrators, system engineers, technical support personnel, network/SAN administrators, and systems integration/development staff, who will be installing, operating, or integrating InfoScale Availability
Knowledge of and hands-on experience with Linux/Unix systems administration.
This course includes practical lab exercises that enable you to test your new skills and begin to transfer those skills into your working environment.
