RMAN>
怎么只报了个参数文件/控制文件的备份过时？ [/B]
I am not sure the exact answer. but according to metalink 134214.1
RMAN not always use incremental backup if it has archivelog backup too.
" Let's use the following RECOVER command as an example:
RMAN> run{
2> allocate channel x type disk;
3> restore datafile 7;
4> recover datafile 7;
5> }
RMAN will first restore datafile 7 from the last incremental
level 0 backup. Then, it will evaluate its two options for the recovery.
One option is to restore incremental level backups that exist since the
last level 0, then finish up with any archivelogs that exist from the
last incremental backup to the current point in time. The second option is
to ignore the incremental backups and simply apply all archive logs from
the level 0 backup until the current point in time. RMAN evaluates both
options and chooses the path that will make recovery occur in the shortest
amount of time.
"
so maybe in this case, RMAN just keep the option open .
