Hi pl do check in metalink for below

1. Note 216664.1 has a port pool table that can be used to determine which port pool coresponds to which ports.
2. Rerun adcfgclone.pl on your Apps tier and select the appropriate port pool.
3. Once this is done, the database connection information in the 8.0.6 Oracle_Home/admin/network//tnsnames.ora should match the connection information in the 9i Oracle Home tnsnames.ora.
