180 Sun ONE Directory Server Installation and Tuning Guide • June 2003
The fault monitor uses the IP addresses and port numbers you specified when
“Configuring the Servers,” on page 176 to carry out probe operations. If Directory
Server is configured to listen on two ports, one for SSL traffic and one for normal
traffic, the fault monitor probes both ports using TCP connect, following the fault
monitoring algorithm used for secure mode ports.
Table C-3 How the Fault Monitor Interprets Probes
Directory Server running in... Probe Used Algorithm
Normal mode ldapsearch 1. Attempt a search.
2. If the search operation results in:
• LDAP_SUCCESS, then the service is considered healthy.
• An LDAP error, then the service must be restarted.
• A problem other than timeout, then the fault monitor
probes again depending on Monitor_retry_count
andMonitor_retry_interval.
•TheProbe_timeout duration being exceeded, then the
fault monitor probes again depending on
Monitor_retry_count and
Monitor_retry_interval.
Potential causes of timeout include heavy loads on the
system, network, or Directory Server instance. Timeout may
also indicate thatthe Probe_timeout value is set too low
for the number of Directory Server instances monitored.
Secure mode (SSL) TCP connect 1. Attempt to connect.
2. If the connection operation:
• Succeeds, then the service is considered healthy.
• Fails, then the service must be restarted.
• ExceedsProbe_timeout, then the service must be
restarted.
