Answer 1

what is this file is it datafile or archive log file ..'/oracle/u01/app/oracle/oracle/product/10.2.0/db_1/logarchive/7603_1_594490386.dbf'.
Can you check if this file is physically present.
If its archive log file and not present physically do this
When the recovery process suggests the non-existent archive log,you need to provide the path to the current online redo log. The current
log can be determined from the following query:
SELECT MEMBER
FROM V$LOGFILE F,
V$LOG L
WHERE L.STATUS = 'CURRENT'
AND L.GROUP# = F.GROUP#;
Once you know the current log, restart the recovery procedure and provide the
path to the log when prompted:
