Oracle full recovery database tutorial
Completely recover the data file rman target/list backup summary; check whether there is a backup. If there is no backup, perform full backup first (it should be backup database) now, you can simulate the deletion of data files in the oracle database to find the data file directory, for example,/u01/app/oracle/oradata/ORCL, and delete all the files with the dbf suffix sqlplus/as sysdbashutdown immediate in the folder; an error will be reported because all the data files have been deleted as shutdown abort. If you disable startup forcibly, you will be prompted that the data file cannot be found, and the rman target/restore database of the database cannot be opened normally; in this case, the dbf file in the ORCL folder has been restored to the recover database. Continue to restore the database.
