also check if you have more than one tnsnames file on the server.
It has been a while since I used Oracle application server but there could be a registry (or some other) setting that is still pointing at another tnsnames.ora file. You did say that you are using the same database name for the new one as the old one.

Thank you all. The problem was solved. We have several Oracle home directories .. not under the same parent directory so 1 of them still was pointing to the previous server and we missed that one (in the tnsnames.ora).

HI can you tell me the OS.This error related to Kernel parameter have you set the kernel parameters.
If you set the kernel parameter definitely it solves your problem
