Hi, Honestly speaking I didn't setup Apps processes in Cold Cluster configuration (Virtual Host) so my comments in that case are purely theoretical. It sounds like Hananto have more experience. HA for Apps parts in most of my projects has been ensured by backup & recovery strategy for really small systems and it doesn't make sense to make more expensive solutions in that case or using Load Balances (Web, Forms) & PCP (Concurrent Processing) for enterprise systems. Cold Clusters however is kind of trade off between to mentioned in above. Jurijs On 6/25/07, Hananto Wicaksono <hananto.wicaksono@xxxxxxxxx> wrote:
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.
