Yes. Recovery is done by applying archive logs only. Firstly RMAN will check at the default archive log destination for availability of required archive logs, if they are not present there, it will ask for the alternate destination fo archive logs.

That RMAN chooses for you. Its going to choose the latest one.

[EDIT TEXT] RMAN RESTORE command will restore a file only & only if restoration is necessary for it.

one day:

1) i created a table, inserted some rows in and committed
2) i made a full online backup while my database was turning in automatic archiving
3) i dropped the table i've create and
4) issued a Point In Time recovering until the time when a did the full backup

my table was recovered but the rows i've inserted were not present
how can u explain that??

Hello,

Can you check alert log and tell exactly what time is the table dropped.

As per your recovery, its supposed to recover your table if you have commited data and did the online backup.

Can you also tell what time you inserted the data and commited comparing with online backup you took.
