About ApplicationHA Management

Last published : Jul 06, 2026
ApplicationHA is a high availability product that provides monitoring capabilities for the applications that run inside a virtual machine. ApplicationHA uses a persistent heartbeat mechanism to communicate the state of the application to the high availability provider in the virtualization infrastructure layer.
When an application that runs inside a virtual machine fails, ApplicationHA tries to restart the application. If ApplicationHA cannot restart the application, it attempts to gracefully restart the virtual machine. If the internal restart does not restore the application, ApplicationHA sends a message to the high availability provider to externally restart the virtual machine. If that fails, the high availability provider may fail over the virtual machine to another virtualization server.
Using the Management Server console, you can perform the ApplicationHA operations in the following virtualization environments:
  • VMware ESX/ESXi
  • Linux Kernel Virtual Machine (KVM)
  • IBM AIX Logical Partitions (LPAR)
  • Oracle VM Server (OVM) for SPARC (Solaris LDOM)
The high availability provider in the VMware environment is VMwareHA. The high availability provider in the KVM, OVM Server for SPARC, and LPAR environments is Cluster Server.
To configure InfoScale Operations Manager to discover virtual machines in these virtualization environments, you must perform the following steps:
  • Add the VMware or the KVM virtual machines as managed hosts to Management Server.
  • Add the LPARs as managed hosts to Management Server.
  • Add the logical domains in an OVM Server for SPARC as managed hosts to Management Server.
