Today we are discussing the error “Exception:TNS-04414: file error”.
Generally, TNS-04414 errors occurred with exception messages using GUI tools like DBCA or NETMGR.
Cause of TNS-04414 error:
Due to found some mysterious character in the network file. While DBCA or NETMGR utility is trying to save network files like sqlnet.ora, tnsnames.ora or listener.ora that time it got this mysterious character and is unable to save it.
Try to modify $ORACLE_HOME/network/admin files (sqlnet.ora, listener.ora and tnsnames.ora) and restart GUI utility and re-initiate task.
