Thanks for the reply, Hananto.
Am not using PCP. The xml file is configured in the way you mentioned.
How do you find out whether ICM is using physical node name and other
concurrent managers on virtual node name?
Cheers,
Joseph

Hi Jurijs,
Thanks for the information. That is just in case if some patches or maybe
autoconfig can overwrite the TNS on Apps Tier, but I am also not sure. I
think it is good also to put our customization on IFILE. :)
Joseph,
From my experience, when configure the failover as described, make sure that
ICM is running using physical node name and other concurrent managers are
running on virtual node name. ICM cannot run when using virtual hostname, so
leave it since it will be automatically detect on which node name it is
actually running. But for other concurrent managers must refer to virtual
hostname so it can failover. As Jurijs said, check also the FND_NODES. It
must contains all the physical nodes name as well as virtual hostname.
CMIIW, you are not using PCP, right ? Just running single node but with
failover capability to standby server (active-pasive). And Yes, always refer
to the virtual hostname when setting the xml file. None of the parameter
refer to the persistent IP/hostname (physical).
Cheers,
Hananto.

Joseph,
It sounds like your Apps configuration is not 100% running on Virtual host.
Your CM-s are running on physical host, is it right?
If you might want to play with Parallel Concurrent Processing feature
which allow you to run CM-s on several hosts at the same time.
Or if you would like to keep those running on physical host then just
before running postclone actions you need to execute
fnd_conc_clone.setup_clean; procedure in order to clean old records in
FND_NODES table. Postclone calls autoconfig which adds proper hostname
to that table.
If you CM-s have been interrupted in abort mode (shutting down a node
for example) then you might considering to run cmclean.sql (available
on Mentalink just enter script name in the search field) script just
before starting up CM-s in the target node.
