Physical Data Replication for ContinentalClusters Using Continuous Access XP

Setting up the Continental Cluster
Configuration
The steps below are the basic procedure for setting up the
ContinentalClusters configuration file and the monitoring packages on
the two clusters. For complete details on creating and editing the
configuration file, refer to Chapter 5, “Building a Continental Cluster.”
1. Generate the ContinentalClusters configuration using the following
command:
# cmqueryconcl -C cmconcl.config
2. Edit the configuration file cmconcl.config with the names of the two
clusters, the nodes in each cluster, the recovery groups and the
monitoring definitions. The recovery groups define the primary and
recovery packages. When data replication is done using Continuous
Access XP, there are no data sender and receiver packages.
Define the monitoring parameters, the notification mechanism (ITO,
email, console, SNMP, syslog or tcp) and notification type (alert or
alarm) based on the cluster status (unknown, down, up or error).
Descriptions for these can be found in the configuration file
generated in the previous step.
3. Edit the continental cluster security file /etc/opt/cmom/cmomhosts
to allow or deny hosts read access by the monitor software.
4. On all nodes in both clusters copy the monitor package files from
/opt/cmconcl/scripts to/etc/cmcluster/ccmonpkg. Edit the
monitor package configuration as needed in the file
/etc/cmcluster/ccmonpkg/ccmonpkg.config. Set the AUTO_RUN flag to
YES. This is in contrast to the flag setting for the application
packages. We want the monitor package to start automatically when
the cluster is formed.
5. Apply the monitor package to both cluster configurations using the
following command:
# cmapplyconf -P /etc/cmcluster/ccmonpkg/ccmonpkg.config
