Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

The health check utility is installed at
/opt/VRTSvcs/rac/healthcheck/healthcheck during the installation of SF Oracle
RAC.
The utility determines the health of the components by gathering information
from configuration files or by reading the threshold values set in the health check
configuration file /opt/VRTSvcs/rac/healthcheck/healthcheck.cf. It displays
a warning message when the operational state of the component violates the
configured settings for the component or when the health score approaches or
exceeds the threshold value. You can modify the health check configuration file
to set the threshold values to the desired level.
The health checks for the LMX, I/O fencing, PrivNIC, and Oracle Clusterware
components do not use threshold settings.
Note: You must set the ORACLE_HOME and CRS_HOME parameters in the configuration
file as appropriate for your setup.
Table 1-4 provides guidelines on changing the threshold values.
Table 1-4
Setting threshold values
Setting the thresholdRequirement
Reduce the corresponding threshold value.To detect warnings early
Increase the corresponding threshold value.
Caution: Using very high threshold values can prevent the
health check utility from forecasting potential problems in
the cluster. Exercise caution with high values.
To suppress warnings
Note: You can schedule periodic health evaluation of your clusters, by scheduling
the utility to run as a cron job.
See “Scheduling periodic health checks for your cluster” on page 87.
For detailed information on the list of health checks performed for each
component, see the appendix List of SF Oracle RAC health checks.
