Using Serviceguard Extension for RAC, 5th Edition, June 2007

Serviceguard Configuration for Oracle 10g RAC
RAC Instances
Chapter 246
RAC Instances
Automated Startup and Shutdown
CRS can be configured to automatically start, monitor, restart, and halt
RAC instances.
If CRS is not configured to automatically start the RAC instance at
Oracle Cluster Software startup, the RAC instance startup can be
automated through scripts using supported commands, such as srvctl
or sqlplus, in a SGeRAC package to start and halt RAC instances.
NOTE srvctl and sqlplus are Oracle commands.
Manual Startup and Shutdown
Manual RAC instance startup and shutdown is supported through the
following commands: srvctl or sqlplus.
Shared Storage
It is expected the shared storage is available when the RAC instance is
started. Since the RAC instance expects the shared storage to be
available, ensure the shared storage is activated. For SLVM, the shared
volume groups must be activated and for CVM, the disk group must be
activated. For CFS, the cluster file system must be mounted.
Oracle Cluster Software requires shared storage for the Oracle Cluster
Registry (OCR) and a vote device. Automatic Storage Management
(ASM) can not be used for the OCR and vote device since these files must
be accessible before Oracle Cluster Software starts. The minimum
required size for the OCR is 100MB and for the vote disk is 20 MB.
The Oracle OCR and vote device can be created on supported shared
storage, including SLVM logical volumes, CVM raw volumes, and CFS
file systems.
