Home -> Community -> Mailing Lists -> Oracle-L -> RE: [SPAM] RE: Weirdness with 'ons' process....
Fairlie,
I found the problem..or, rather, Niall did. See MetaLink Doc ID 284602.1 for more details.
Thanks,
-Mark

Importance: Low Hi Mark, Listener load balancing does not require ONS and the ONS daemon can be stopped using onsctl stop Regards, Fairlie "Bobak, Mark" <Mark.Bobak_at_il.proquest.com> wrote: 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. -Mark -- Mark J.

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 "Bobak, Mark" <Mark.Bobak_at_il.proquest.com> wrote: 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 -- Mark J.
