Oracle Backup Misbehavior

Question

Hello,
iam running into a strange problem while doing a backup via Oracle Enterprise Tool under Oracle 11g:
1. Login: sys as sydba
2. Backup Setting are on "Image Copy"
2.1 Keep most generally default settings
2.2 Test Disk Backup successfully
3. Schedule Backup
3.1 Whole database
3.2 Full Backup
3.3 Online
3.4 Disk
3.5 One time
4. Waiting until orcl is ready and backup job is succeeded
5. Altering the database
5.1 e.g. filling an empty tablespace with tables
5.2 or changing an existing database table content through a database tool (e.g. DVisualizer)
6. Perform Recovery
6.1 Recovery Scope: datafile
6.2 Restore datafile
6.3 select the afected datafile
6.4 the most recent backup
6.5 restore to default location
6.6 Submit job und wait till succeeded
From now on the problem starts:
- If i am looking now at the datafile i can see the status = Recover. I can access the tablespace, but not my data (datafile)
- Looking at the function "Perform Recover" => the Oracle Advisor is recommending a Recovery
- Performing the Recovering => I can afterwards access the tablespace, but there is not the state i have backuped before and i wanted to restore
What iam doing wrong here?
Please advice.
Any help is appreciated.
If you have any guideline how i can easily do a simply Oracle backup it would be helpful as well.

Answer 1

If I understand you correctly you performed a COMPLETE recovery,rsp. EM triggered this. Do you want to get back the state of the database BEFORE the changes? Then you must restore/recover incompletely, just before the point in time the changes were done.
