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

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
