Figure 15: Initial configuration with GiCAP and Serviceguard
Imagine that db1 has a serious failure and is no longer running. The package is defined with the
AUTO_RUN option, so Serviceguard will automatically fail it over to db2. Scripts are defined to
provide customized processing on the start-up and shutdown of the package. Before the package is
started on db2, the start-up script contacts the Group Manager (on host ap1) to seize the available
core usage rights from db1 and activate the six additional processor cores on db2.
