Serviceguard Extension for RAC Version A.11.18 Release Notes, 1st Edition, June 2007

Serviceguard Extension for RAC Version A.11.18 Release Notes
What’s in this Version
Chapter 1 13
Like system multi-node packages, multi-node packages do not fail over,
and can run on more than one node at a time. Unlike system multi-node
packages, they do not have to run on every active node in the cluster, but
can be configured to run on specific nodes.
Multi-node packages function for CFS in much the same way as the
STORAGE_GROUP parameter functions for CVM 3.5. They allow an
application package to build a dependency on another package, such as a
dependency on a cluster file system package or disk group package.
CFS packages use a new parameter set, added to the package
configuration file, that you can use to create dependencies. This
parameter ensures that a package will not start on a node unless the
package it depends on is up and running on that node.
