Today we are discussing about error “Exception:TNS-04414: file error”.
Generally TNS-04414 errors occurred with exception message using GUI tools like DBCA or NETMGR.
Cause of TNS-04414 error:
Due to found some mysterious character in network file. While DBCA or NETMGR utility is trying to save network file like sqlnet.ora, tnsnames.ora or listener.ora that time it got this mysterious character and 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.
We have seen problem with sqlnet.ora in most of cases of this error. When DBCA is open sqlnet.ora and save it, error is occurring.
