ALEMU make following steps:
1.- alter database backup controfile to trace noresetlogs;
2.- Edit your dump file and modify MAXDATAFILES value.
Normally you can find that file in $ORACLE_HOME/rdbms/log.
3.- Shutdown your database.
4.- Startup nomount your database.
5.- Run the 'create controlfile' command in your dump file.
6.- alter database open;
Maybe, before that, it's interesting you make a full backup and,
after that, another full backup.
