Hi, I am trying to recover 2 datafiles via EM console: maintenance tab -> perform recovery. I am on Win XPSP2 with 10gR2.
My DB is in Archive Log mode so I should be able to recover from my archive logs and redo logs located in the flashback area, and correctly pointed by the initialization parameters.
At the end of the steps, I can see on the console screen the output of RMAN, but there are not enough indications to understand where to dig further:

***************************************************************
As mentioned my archive logs are in the flash recovery area and not on tape so I am not sure why RMAN seems to attempt to recover from tape as well after the attempt from disk is failing. My knowledge of RMAN though is zero and really don't know where the problem can be.
This is the output of RMAN> show all;

*******************************************************
Reason I am trying to recover these 2 datafiles is because due to an error they have been filled up, I am not even allowed to allocate additional space for them and they just show in the "recover" status instead of "online".
Thanks in advance for your help.

Hi Michel thanks.
I never configured tapes and don't use them as this is all happening on my laptop for practice. I have archived logs, and I can see them in the flash recovery area. When I click on maintenance tab in the EM console and then on Perform Recovery, I don't seem to find options to either recover or restore - I just follow the guided steps, and when submit, I expect the files to begin recovery, instead I receive that error.
What I would like to accomplish is recovering the 2 data files as they were yesterday or a couple of days back. I think I have all archive logs from at least one week back, so I should be able to do it ... can you please give me some indications (with or without the use of EM console)?
Thanks a lot!

Michel, here I am trying to restore from a back up dated june 27 named : 'BACKUP_ORCL4_00004_062707111919'. This is on my hard disk, and EM is able to see it and place as an option during the steps.
But at the end when submitting, I am getting the same error:

CHANGE ALL SBT_TAPE ENTRIES WITH DISK
change sbt_tape to disk type.

michel, dreamz, thank you - the problem is finally fixed and I was able to recover my DB to 24 hours back.
I modified RMAN as follows:
• RMAN TARGET /
• RMAN> CONFIGURE DEVICE TYPE 'SBT_TAPE' CLEAR;
• RMAN> CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' clear;
Thanks.
