Serviceguard Configuration for Oracle 9i RAC
Using Packages to Configure Startup and Shutdown of RAC Instances

Using the Command Line to Configure an Oracle RAC Instance
Package
Serviceguard Manager provides a template to configure package
behavior that is specific to an Oracle RAC Instance package. The RAC
Instance package starts the Oracle RAC instance, monitors the Oracle
processes, and stops the RAC instance.
The configuration of the RAC Instance Package make use of the
Enterprise Cluster Master Toolkit (ECMT) to start, monitor, and stop the
Oracle database instance. For details on the use of ECMT, reference
ECMT documentation.
Each Oracle RAC database can have database instance running on all
nodes of a SGeRAC cluster. Therefore, it is not necessary to failover the
database instance to a different SGeRAC node. This is the main
difference between an Oracle RAC Instance Package and a single
instance Oracle package.
Information for Creating the Oracle RAC Instance Package on a
SGeRAC Node Use the following steps to set up the pre-package
configuration on a SGeRAC node:
1. Gather the RAC Instance SID_NAME. If you are using Serviceguard
Manager, this is in the cluster Properties.
Example: SID_NAME=ORACLE_TEST0
For an ORACLE RAC Instance for a two-node cluster, each node
would have an SID_NAME.
2. Gather the RAC Instance package name for each node, which should
be the same as the SID_NAME for each node
Example: ORACLE_TEST0
3. Gather the shared volume group name for the RAC database. In
Serviceguard Manager, see cluster Properties.
Example: /dev/vgora92db
4. Create the Oracle RAC Instance Package directory
/etc/cmcluster/pkg/${SID_NAME}
Example: /etc/cmcluster/pkg/ORACLE_TEST0
