Designing a Continental Cluster
Support for Oracle RAC Instances in a Continentalclusters Environment
Chapter 2 139
For details on how to configure an Oracle RAC instance in a
Serviceguard package, refer to the Using Serviceguard Extension for
RAC user’s guide. In the Continentalclusters environment, you can
configure each RAC instance in a failover type package or you can
configure all RAC instances in a single multi-node package.
6. Setup the environment file. Instead of one environment file for each
continental cluster application package, there is only one
environment file for each set of Oracle RAC instance packages
accessing the same database. This file can be located anywhere
except the directory where the Oracle RAC instance package
configuration and control files reside. Only one environment file can
reside under one directory. The setup of the file is the same as what
is described in section, “Physical Data Replication using Special
Environment files” on page 58 of this chapter, with the exception of
the PKGDIR variable.
The value of the PKGDIR variable must be the directory where this
environment file resides.
For specific information on how to setup the environment file, see
Chapter 3 under section, “Configuring Packages for Disaster
Recovery” Chapter 4 under section, “Configuring Packages for
Automatic Disaster Recovery” or Chapter 5 under section
“Configuring Serviceguard Packages for Automatic Disaster
Recovery”.
Be sure to place this environment file in the same path on all nodes
of both the primary and recovery clusters in a recovery pair. You
must name the environment file using your package name as the
prefix. For example, <package name>_xpca.env. You must
uncomment all the AUTO variables in the environment file.
Based on the disk arrays in your environment, refer to the
corresponding chapters of this manual for more information on
configuring the environment file for your storage.
7. Set up the Continentalclusters Oracle RAC specification file. The
existence of file /etc/cmconcl/ccrac/ccrac.config servers as an
enabler for Continentalclusters Oracle RAC support. A template of
this file is available in /opt/cmconcl/scripts directory.
Edit this file to suit your environment. After editing, move the file to
/etc/cmconcl/ccrac/ccrac.config directory on all nodes in the
participating clusters. Use the following steps to set up the file:
