How the Package Manager Works
Chapter 350
Figure 3-7 After Package Switching
Failover Policy The Package Manager selects a node for a failover
package to run on based on the priority list included in the package
configuration file together with the failover_policy parameter, also in
the configuration file. The failover policy governs how the package
manager selects which node to run a package on when a specific node has
not been identified and the package needs to be started. This applies not
only to failovers but also to startup for the package, including the initial
startup. The two failover policies are configured_node (the default) and
min_package_node. The parameter is set in the package configuration
file.
If you use configured_node as the value for the failover policy, the
package will start up on the highest priority node available in the node
list. When a failover occurs, the package will move to the next highest
priority node in the list that is available.
