Symantec ApplicationHA provides monitoring capabilities for applications running inside logical partitions in the IBM PowerVM virtualization environment. Symantec ApplicationHA adds a layer of application awareness to the core high availability (HA) functionality offered by Symantec™ Cluster Server (VCS) in the management LPAR.

Symantec ApplicationHA is based on VCS and uses similar concepts such as agents, resources, and service groups. However, it does not include the high availability cluster components such as the Group Membership and Atomic Broadcast (GAB), Low Latency Transport (LLT), and Veritas Fencing (VxFEN). Symantec ApplicationHA has a lightweight server footprint that allows faster installation and configuration.

Key benefits include the following:

Out of the box integration with VCS.
Full visibility and control over applications with the ability to start, stop, and monitor applications running inside managed LPARs.
High availability of the application as well as the managed LPAR inside which the application runs.
Graded application fault-management responses such as:-
- Application restart
- ApplicationHA-initiated, graceful internal reboot (soft reboot) of a managed LPAR
- VCS-initiated, external reboot (hard reboot) of managed LPAR
- Failover of the managed LPAR to another VCS node.
Specialized Application Maintenance mode, in which ApplicationHA allows you to intentionally take an application out of its purview for maintenance or troubleshooting.
