Package for the RAC database in the recovery cluster:
1. Create a Site Controller Package configuration file using the dts/sc and
dts/recovery_xpca3dc modules.
# cmmakepkg -m dts/sc –m dts/recovery_xpca3dc \
/etc/cmcluster/hrdb_sc/hrdb_sc.config
2. Edit the hrdb_sc.config file and specify the following:
• Name for the package_name attribute
package_name hrdb_sc
• Names of the nodes explicitly using the node_name attribute
• The Site Controller Package directory for the dts/dts/dts_pkg_dir attribute.
dts/dts/dts_pkg_dir /etc/cmcluster/hrdb_sc
