William,
Are you sure that your environments on both nodes point
to the CRS_HOME and not the ORACLE_HOME. I know
of issues where onsctl ping would work
from the CRS_HOME but not from the ORACLE_HOME
Also a trace of srvctl with SRVM_TRACE=DEBUG might
help you to find out what exactly is causing the hang on node 1
Thanks

Fairlie,
Thanks for the response. Here is another piece to the puzzle which to me
just adds to the confusion. On node 1...
$ srvctl status nodeapps -n brownshoe
hangs
$ onsctl ping
Number of onsconfiguration retrieved, numcfg = 2
onscfg[0]
{node = brownshoe.ucdavis.edu, port = 6200}
Adding remote host brownshoe.ucdavis.edu:6200
onscfg[1]
{node = tenspeed.ucdavis.edu, port = 6200}
Adding remote host tenspeed.ucdavis.edu:6200
ons is not running ...
$
on node 2 I see...
$ srvctl status nodeapps -n tenspeed
VIP is running on node: tenspeed
GSD is running on node: tenspeed
Listener is not running on node: tenspeed
ONS daemon is running on node: tenspeed
$ onsctl ping
Number of onsconfiguration retrieved, numcfg = 2
onscfg[0]
{node = brownshoe.ucdavis.edu, port = 6200}
Adding remote host brownshoe.ucdavis.edu:6200
onscfg[1]
{node = tenspeed.ucdavis.edu, port = 6200}
Adding remote host tenspeed.ucdavis.edu:6200
ons is not running ...
$
Why does node 1 hang and why does srvctl show ons running but onsctl ping
says no. I don't understand the discrepancy.
Thanks.

William,
In brief this is all a part of the FAN framework where a listener
registers with ONS.
You shouldn't have this problem if you set
SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener> to OFF
which should disable ONS subscription
If you still have an issue can you paste/send the output of
onsctl debug
Thanks

Greetings,
On a two node RAC cluster, Oracle 10.2.0.3.0 Enterprise Edition on RHEL4
64-bit using CRS.
In my listener.log I see numerous occurrences of the message...
WARNING: Subscription for node down event still pending
In searching for the web I find it commonly suggested that the
listener.ora file by updated to include the parameter
SUBSCRIBE_FOR_NODE_DOWN_EVENT_LSNR=
This is where I get lost. I am unable to find any documentation as to
what constitutes a node down event and what the ramifications are. What
is a node down event?
I have searched the Oracle docs for this parameter, nothing is found.
Searching for listener.ora refers me to the net services guide but I am
unable to find specific syntax for this parameter, it doesn't even
appear in the index. Searching also refers me to the configuring the
listener.ora in the various clusterware guides but again, no syntax for
the parameter is given nor is it listed in the index. I'm stumped.
What we are seeing is that our application is using web logic and it
appears that after a while connections and querying start to slow down
and restarting the listener temporarily appears to resolve the issue.
Some of the notes about the warning message indicates that the listener
encountering some memory issues but I really can't find any explanations
of this anywhere.
If anyone can shed any light on this or point me to some documentation
on what this means or how to troubleshoot this problem I would be very
grateful.
Thanks.
