Monitoring edirectory in cluster monitor scripts

When monitoring edirectory in a cluster monitor script the following two commands do not produce consistent  and quick results, thus causing potential failure of the monitor script while edirectory is working.

  exit_on_error rcndsd status
  exit_on_error ndsstat

In a cluster monitor script it is better to ensure that ndsd process is working by using.

  exit_on_error pidof ndsd

Additional functionality was added in OES11 SP2. The newer method monitors ndsd at the cluster level instead of the resource level. To setup monitoring on OES11 SP2, refer to the following document:
