Control files     i.e. for example /u01/oracle/app/oradata/pavan/tntt/control.ctl
Redo log files i.e. for example /u01/oracle/app/oradata/pavan/tntt/redo01.log
                                             /u01/oracle/app/oradata/pavan/tntt/redo02.log
Data files        i.e. for example /u01/oracle/app/oradata/pavan/tntt/system01.dbf
                                        /u01/oracle/app/oradata/pavan/tntt/sysaux01.dbf
                                        /u01/oracle/app/oradata/pavan/tntt/undotbs01.dbf
                                        /u01/oracle/app/oradata/pavan/tntt/users01.dbf


To know these paths use the following commands/queries in sql prompt:
