启动探测程序

Monitor_start 方法获取 Rt_basedir 特性的值以构造 PROBE 程序的完整路径名。 此方法将使用 pmfadm (-n -1, -t -1) 的无限重试选项启动探测程序,这意味着如果该探测程序无法启动,PMF 将在无限长的时间间隔内尝试无限多次地启动该程序。


# Find where the probe program resides by obtaining the value of the
# RT_BASEDIR property of the resource.
RT_BASEDIR=`scha_resource_get -O RT_BASEDIR -R $RESOURCE_NAME -G \
$RESOURCEGROUP_NAME`

# Start the probe for the data service under PMF. Use the infinite retries 
# option to start the probe. Pass the resource name, type, and group to the 
# probe program. 
pmfadm -c $RESOURCE_NAME.monitor -n -1 -t -1 \
   $RT_BASEDIR/dns_probe -R $RESOURCE_NAME -G $RESOURCEGROUP_NAME \
   -T $RESOURCETYPE_NAME
