Chapter1Introducing SymantecApplicationHAThis chapter includes the following topics: What is Symantec ApplicationHA Which applications can I monitor? Components of Symantec ApplicationHA Symantec ApplicationHA user privileges Symantec ApplicationHA agentsWhat is Symantec ApplicationHAApplicationHA is one of the application availability management solutions fromSymantec. It provides monitoring capabilities for applications running insidevirtual machines managed by a VMware vCenter Server. Symantec ApplicationHAadds a layer of application awareness to the core HA functionality offered byVMware virtualization technology.Symantec ApplicationHA is based on Veritas Cluster Server (VCS) and usessimilar concepts such as agents, resources, and service groups. However, it doesnot include the high availability cluster components such as the Group Membershipand Atomic Broadcast (GAB) and Low Latency Transport (LLT). SymantecApplicationHA has a lightweight server footprint that allows faster installationand configuration.Key benefits include the following: Out of the box integration with VMware vCenter Server.
12Introducing Symantec ApplicationHAWhat is Symantec ApplicationHA Full visibility and control over applications with the ability to start, stop, andmonitor applications running inside virtual machines. Standardized way to manage applications using a single interface that isintegrated with either VMware vSphere Client or the VOM Management Serverconsole. Specialized Application Maintenance mode, in which ApplicationHA allowsyou to intentionally take an application out of its purview for maintenance ortroubleshooting. Integration with VMware SRM Server that provides the capability to resumeapplication monitoring after the virtual machines are started on the recoverysite.How Symantec ApplicationHA works with VMware vCenter ServerSymantec ApplicationHA communicates directly with VMware HA. ApplicationHAconveys the application health status in the form of an application heartbeat.This allows VMware HA to automatically reset or restart a virtual machine if theapplication heartbeat is not received within a specified interval.The following figure displays the sample deployment of Symantec ApplicationHA.

14Introducing Symantec ApplicationHAWhat is Symantec ApplicationHAApplicationHA provides a vCenter plug-in for integration with VMware vSphereClient and adds the following interfaces for performing application monitoringtasks. These interfaces appear in the vSphere Client after you install the SymantecHigh Availability Console. Symantec High Availability tab: The Symantec High Availability tab is theprimary interface for performing the application monitoring operations on avirtual machine.From this view you configure application monitoring and then monitor andcontrol the configured application on the virtual machine. After configuringapplication monitoring, the Symantec ApplicationHA view displays the stateof the application and the component dependencies.The following figure displays the Symantec High Availability tab where a customapplication is configured for monitoring.
Introducing Symantec ApplicationHAWhat is Symantec ApplicationHA Symantec High Availability dashboard: The Symantec High Availabilitydashboard is the primary interface for administering the configuredapplications on a VMware cluster or datacenter. After configuring applicationmonitoring, the Symantec High Availability dashboard displays the state ofthe application.The following figure displays the Symantec High Availability dashboard withvarious applications are configured for monitoring with ApplicationHA on variousvirtual machines in a data center.15
16Introducing Symantec ApplicationHAWhat is Symantec ApplicationHAHow ApplicationHA worksSymantec ApplicationHA architecture uses the agent framework to monitor thestate of the applications and their dependent components running on the virtualmachines. Symantec ApplicationHA agents monitor the overall health of theconfigured applications by running specific commands, tests, or scripts. For moredetails, see the agent functions section of the application-specific agent guidesor the generic agent guide distributed with ApplicationHA.The ApplicationHA Heartbeat agent is configured when you configure applicationmonitoring. The Heartbeat agent sends the application heartbeat to VMware HA.Symantec ApplicationHA uses the application heartbeat as the communicationmedium to convey the status of the application to VMware HA.If an application fails, ApplicationHA performs the following actions in thespecified sequence.1.The ApplicationHA agents attempt to restart the application for a configurablenumber of times.2.ApplicationHA gracefully restarts the virtual machine. This action isperformed only if you have configured ApplicationHA-initiated virtualmachine restart. This action is not performed if you have not configuredApplicationHA-initiated virtual machine restart.3.If the agents are unable to start the application, Symantec ApplicationHAstops sending the application heartbeat to VMware HA.4.Depending on the configuration, VMware HA takes the necessary c
