Serviceguard Configuration for Oracle RAC
Using Packages to Configure Startup and Shutdown of RAC Instances
Chapter 260
Using Packages to Configure Startup and
Shutdown of RAC Instances
To automate the startup and shutdown of RAC instances on the nodes of
the cluster, you can create packages which activate the appropriate
volume groups and then run RAC. Refer to the section “Creating
Packages to Launch Oracle RAC Instances”
NOTE The maximum number of RAC instances is 127 per cluster
Starting Oracle Instances
Once the Oracle installation is complete, ensure that all package control
scripts are in place on each node and that each
/etc/rc.config.d/cmcluster script contains the entry
AUTOSTART_CMCLD=1. Then reboot each node. Within a couple of minutes
following reboot, the cluster will reform, and the package control scripts
will bring up the database instances and application programs.
When Oracle has been started, you can use the SAM process
management area or the ps -ef command on both nodes to verify that
all RAC daemons and Oracle processes are running.
Starting Up and Shutting Down Manually
To start up and shut down RAC instances without using packages, you
can perform the following steps.
• Starting up involves the following sequence:
1. Start up the cluster (cmrunnode or cmruncl)
2. Activate the database volume groups or disk groups in shared
mode.
3. Bring up Oracle in shared mode.
4. Bring up the Oracle applications, if any.
• Shutting down involves the following sequence:
