Restarting the Monitor

To restart the monitor, the Update method must locate the script that implements the probe program. The probe program resides in the base directory for the data service, which is pointed to by the Rt_basedir property. Update retrieves the value of Rt_basedir and stores it in the RT_BASEDIR variable, as follows.

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

Update then uses the value of RT_BASEDIR with pmfadm to restart the dns_probe program. If successful, Update exits with success and sends a message to that effect to the administrative user. If pmfadm cannot launch the probe program, Update exits with failure status and logs an error message.
