Fairlie,
I found the problem..or, rather, Niall did. See MetaLink Doc ID
284602.1 for more details.
Thanks,
-Mark

Hi Mark,
Listener load balancing does not require ONS and the ONS daemon can be
stopped using onsctl stop

Hi Fairlie,
Yes, it's running on all nodes.
No, I'm not on AIX.
I have confirmed the ports are ONS, by looking at ons.config
file.
I'm not using FAN or FCF, but I am doing listener load
balancing. Does that require ons? If not, how do I turn it off? I've
been searching Oracle docs, but info on ONS seems to be pretty scarce.

Hi Mark,
Is ONS running on all nodes?
Can you check the same by running onsctl ping or ps -ef | grep
ons
The only related issue I know of is
Bug 3972424 10.1.0.3.0 LISTENER HANGS INTERMITTENTLY (ONS)
on AIX.
Are you on AIX?
You can confirm that the ports have to do with ONS by checking
the
port in $ORACLE_HOME/opmn/conf/ons.config file
If you are not using FAN or FCF you may as well turn ONS off
Regards,
Fairlie

Hi,
I'm running a 10gR2 (10.2.0.2) 64-bit RAC cluster, three
nodes on DL-585s (configured w/ 4 dual core CPUs and 32GB of RAM). I've
been doing some fairly large-scale load testing, pointing our
preproduction environment at this cluster, and seeing some great
performance results.
However, I've been seeing a weird anomaly on two of the
three boxes. If I run:
netstat -an|grep -c ":6101 "
on each of the three nodes, one node reports zero, one
reports 41,446 and one reports 63,961! These connections are all on the
local loopback. Where are these coming from? I know (or I think I
know) that this has to do with 'ons'. I haven't found much info on
ONS.. I know it has to do with FAN, which I have not implemented at
this point. Is this "normal"? If so, why the huge difference in
distribution of the connections across nodes? (Oh, also, the status of
these thousands of connections is 'TIME_WAIT'.)
As this point, it doesn't seem to be negatively
affecting performance, but it sure seems odd....anyone have any clues
for me??
AdvThanksance,
-Mark
