Obtaining Property Values

This program requires the values of the following properties:

• Thorough_probe_interval – To set the period during which the probe sleeps

• Probe_timeout – To enforce the timeout value of the probe on the nslookup command that does the probing

• Network_resources_used – To obtain the IP address on which DNS is running

• Retry_count and Retry_interval – To determine the number of restart attempts and the period over which to count them

• RT_basedir – To obtain the directory that contains the PROBE program and the gettime utility

The scha_resource_get() function obtains the values of these properties and stores them in shell variables, as follows:

PROBE_INTERVAL=`scha_resource_get -O Thorough_probe_interval \
-R $RESOURCE_NAME -G $RESOURCEGROUP_NAME`

PROBE_TIMEOUT_INFO=`scha_resource_get -O Extension -R $RESOURCE_NAME \
-G $RESOURCEGROUP_NAME Probe_timeout` 
Probe_timeout=`echo $probe_timeout_info | awk '{print $2}'`

DNS_HOST=`scha_resource_get -O Network_resources_used -R $RESOURCE_NAME \
-G $RESOURCEGROUP_NAME`

RETRY_COUNT=`scha_resource_get -O Retry_count -R $RESOURCE_NAME -G \
$RESOURCEGROUP_NAME`

RETRY_INTERVAL=`scha_resource_get -O Retry_interval -R $RESOURCE_NAME -G \
$RESOURCEGROUP_NAME`

RT_BASEDIR=`scha_resource_get -O RT_basedir -R $RESOURCE_NAME -G \
 $RESOURCEGROUP_NAME`

For system-defined properties, such as Thorough_probe_interval, the scha_resource_get() function returns the value only. For extension properties, such as Probe_timeout, the scha_resource_get() function returns the type and value. Use the awk command to obtain the value only.
