Virtual Business Services (VBS) is a feature that represents a multi-tier application as a single consolidated entity in Veritas Operations Manager (VOM). It builds on the high availability and disaster recovery features provided by Symantec products, such as, Veritas Cluster Server (VCS) and Symantec ApplicationHA. VBS enables administrators to improve operational efficiency of managing a heterogeneous multi-tier application.
You can control VBS from the VOM graphical user interface and the VBS command line interface (CLI).
When you install SFHA, the VBS installation packages, VRTSvbs and VRTSsfmh, are automatically installed on the nodes. From the VOM interface, you can define a VBS that consists of service groups from multiple clusters. You can also use the VBS CLI to perform command line operations on that VBS.
The clustering solutions that are offered today can only manage applications running on the same operating system. So, deploying the clustering solutions for a multi-tier, cross-platform setup can be difficult to manage.
VBS can work across a heterogeneous environment to enable IT organizations to ensure that the applications across tiers can be made highly available. A typical multi-tier environment comprises of a database on a UNIX server, applications running in a Kernel-based Virtual Machine (KVM) on a Linux server, and a Web server on a VMware virtual machine.
VBS works across the heterogeneous environment to communicate between local operating systems to see the end-to-end state of multi-tier applications and to control start and stop ordering of the applications. With VBS there are relationships between tiers that you can customize to fit your environment. You can set up policies for the events that result in a failure or for the specific events that happen on tiers. For example, you can set up a policy that restarts the application service groups when the database service group fails over to another node.

You can configure and manage a VBS created in VOM by using the VOM VBS Availability Add-on utility. You can also control a VBS from the VBS CLI, but you cannot create a VBS from the VBS CLI.
The VBS Availability Add-on utility enables you to:
