Validating the Configuration

The following table shows the status of Continentalclusters packages in a recovery pair when each cluster is running normally and no recovery has taken place.

Use the following steps to ensure the components are functioning correctly:

1.Make sure all daemons are running.

# ps -ef grep cmcl

Two important Continentalclusters daemons are cmclsentryd and cmclrmond.

2.Check the cluster configuration on each cluster using the cmviewcl -vcommand.

a.Ensure that each primary package is running correctly.

b.Ensure that the data sender packages (if any are used for logical data replication) are running correctly.

c.Ensure that the data receiver packages (if any are used for logical data replication) are running correctly.

d.Ensure that the Continentalclusters monitor package is running correctly on each monitoring cluster.

3.On all nodes, use the tail -f /adm/syslog/syslog.logcommand to check the end of the SYSLOG file for errors.

4.On nodes where packages are running, check all package log files for errors, including application packages and the monitor package.

5.Use the following command to verify the correct operation of the Continentalclusters daemon:

# /opt/cmom/tools/bin/cmreadlog -f /var/adm/cmconcl/sentryd.log

6.Make sure the Continentalclusters monitor packages (default name ccmonpkg) on each cluster fails over properly if a node fails.
