Solution:

This occurs due to incorrect entries in the dbc file. Make sure that the dbc file is created without any issues.

Tried generating dbc file, it came back with the following error. Use $COMMON_TOP/admin/install/adgendbc.sh


Params=fnd_jdbc_stmt_cache_free_mem=TRUE
fnd_jdbc_buffer_min=1
fnd_jdbc_buffer_max=5
fnd_jdbc_buffer_decay_interval=300
fnd_jdbc_buffer_decay_size=5
fnd_jdbc_usable_check=false
fnd_jdbc_context_check=true
fnd_jdbc_plsql_reset=false


Unique constraint error (00001) is OK if key already exists
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
Database connection to jdbc:oracle:thin:@xxxx.xxxx.xx.xx:1526:PROD failed

This was an issue with wrong /etc/hosts entry. Make sure that all the entries in the hosts file are properly mapped to ip address
