Cluster start and stop
The following sections describe the process for starting and stopping Oracle 10g Clusterware.
Start and stop Oracle Clusterware 10g
Placing the start and stop of Oracle Clusterware in Serviceguard packages ensures that the shared
storage required by Oracle Clusterware is available.
When halting the Serviceguard cluster (“cmhaltcl –f”), the package dependencies ensure that the
Oracle Clusterware packages are halted first before the cluster file systems are unmounted.
When using “crsctl stop crs” to stop Oracle Clusterware while Oracle RAC instances are
running, stopping Oracle Clustware causes the instances to shutdown abort. This is the default
behavior since other shutdown modes may not complete in time for Oracle Clusterware to stop in a
timely manner.
If a different Oracle RAC instance shutdown mode (for example normal, immediate) is desired, the
instances should be halted prior to initiating Oracle Clusterware shutdown.
Start and stop Oracle RAC 10g Instance
In this sample configuration, the Oracle RAC instances startup and shutdown are controlled by Oracle
Clusterware.
