RMAN "unrecoverable database"

Question

Hello,
i am getting 2 entries with this check:
RMAN> report unrecoverable database;
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
166 full or incremental /u01/oradata/image/datafile34.dbf
167 full or incremental /u01/oradata/image/datafile35.dbf
So, i backuped those files manually. After this manual backup i only have the file 167 left in the "unrecoverable database" list. Next Day the command reports again both files as unrecoverable (at eveing there is an inc 1 backup). I checked the v$backup and both files are marked as "Available" in RMAN "list backup". Im also syncing the catalog and crosscheck it with the mediamanager every week. There are no errors in the alert log or any other logs. The datafiles are manually added from time to time, always with the same procedure and we had no problems so far with that. Every week we run a inc 0 full backup with no errors.
I have no more ideas where the problem is. Please help me :)

This is not a problem kaufmac.
"report unrecoverable database" will always show any datafile belonging to any tablespace that had any "unrecoverable" operation performed on its objects.
An example:
D:\>rman target /
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
connected to target database: TEST (DBID=1858403612)
RMAN> report unrecoverable database;
using target database controlfile instead of recovery catalog
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
Now if I move emp table from Tablespace USERS to DATA
SQL> alter table emp move tablespace data;
Table altered.
SQL>
D:\>rman target /
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
connected to target database: TEST (DBID=1858403612)
RMAN> report unrecoverable database;
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
2 full or incremental D:\ORACLE\ORA10G\ORADATA\TEST\DATA_01.DBF
RMAN>
So, it depends on what "unrecoverable" operations are performed on it in after your backups. So the question you will have to find the answer is "What are unrecoverable operations on datafiles?"
