SYMPTOM(s):
AdminServer hangs for 75 seconds before starting up on AIX.
OS hostname resolution is set to use DNS first.
FACT(s) (Environment):
IBM AIX
Progress/OpenEdge Versions
CAUSE:
The first DNS server accessed is either not available or cannot resolve the hostname. AIX OS RES_RETRY and RES_TIMEOUT defaults cause a 75 second delay before trying the next DNS server or the hosts file:
The default for RES_TIMEOUT is 5 seconds. The minimum value can be 1 second.
The default for RES_RETRY is 4 times and the minimum value can be 0, but it has been known to cause problems thus a recommendation to use a minimum of 1
The 75 sec timeout period comes from two values RES_RETRY and RES_TIMEOUT.
The DNS client will try to contact the DNS server, then if it doesn't get
an answer back it will wait 5 seconds and try again, then it will wait 10 secs and try again,
20 sec and try again, 40 secs and try again.
5 + 10 + 20 + 40 = 75 secs
FIX:
Reconfigure the RES_RETRY and RES_TIMEOUT defaults to values that will allow the timeout to occur faster.
Alternatively, configure the order of name resolution in the /etc
etsvc.conf file in order to set the order of name resolution to local /etc/hosts, then dns, and then, only if your organization has one, NIS + server.
Set the appropriate entries in the hosts file.
