Applications: Tasks Tab
Tasks are a generalization and extension of start, stop, and monitor scripts. Task types are determined by when
the tasks run, and include the following:
■
Network Conguration – This is the rst type of task that runs when applications start and is intended to
launch dnscmd or DNSUpdate. The task can launch a batch script containing multiple dnscmd commands.
Network Conguration tasks are the only types of task that can vary between Primary and Secondary
servers.
■
Periodic – These tasks are run at specic congurable intervals.
■
Pre/Post Start – These tasks run before and after services start on the active server.
■
Pre/Post Stop – These tasks run before and after services stop on the active server.
■
Pre/Post Shadow – These tasks run before and after the Data Rollback Module creates a shadow copy on
the active server (Not available in this release).
■
Rule Action – Congure these tasks to run in response to a triggered rule or when a service fails its check.
Tasks can be dened and implemented by plug-ins or by the user, or they can be built-in tasks dened by
vCenter Server Heartbeat. User dened tasks are implemented as command lines, which can include launching
a batch script. Examples of built-in tasks include monitoring a protected service state on the active and passive
servers. An example of a plug-in-dened task is the discovery of protected data and services for a particular
application.
The vCenter Server Heartbeat Applications: Tasks page provides a list of tasks and associated status information,
as well as features to quickly manage tasks.
