Something went wrong with our backup. What I did
shutting down db
recover the backup
after that I got this error
ORA-01122: Datenbank-Datei 2 bringt Fehler bei Verifizierungspruefung ORA-01110: Datendatei 2: 'D:\ORACLE\ORA92ABO\ABO\UNDOTBS01.DBF' ORA-01207: Datei neuer als Kontrolldatei - alte Kontrolldatei
the controlfile is at C:\oracle ... and the database files are at d:\oracle\ora92abo...
My guess is that the backupprogramm between backing up the d:\oracle files and the c:\controlfile the database restarts. so there is a moment between the backups where the database is running.
Guess thats bad.
I googled that the UNDOTBS01.DBF has something to do with cloning, with we don't use/need at the moment.
EDIT: Details to the backup method
step 1: shutdown via
spool d:\oracle\01shutdon.log connect / AS SYSDBA shutdown immediate exit
backup the database folder with syncback to NAS backup the controlfile with xcopy to NAS
spool d:\oracle\02startup.log connect / AS SYSDBA startup exit
