Rolling forward the standby database by using primary database incremental backups

Scenario :

The archive gap is noted in the standby database alertlog as below. The required archivelog for recovery is not found in the primary and is been deleted in both the primary and standby unfortunately.

In this case the below is the recovery needed to synchronize the standby with primary. This incremental recovery only works from 10g onwards.

Check the current SCN in the standby, that will be needed to take backup from that SC Number.

User managed Cold backup & Hot backup mixup restoration scenario

How to restore a database which has a valid backup files taken from two different backup methods.

Suppose a database has 4 datafiles and On monday i have taken a backup of 2 datafiles using user managed cold backup (for some reasons didnt take backup of remaining 2 datafiles). And on tuesday i have taken the remaining 2 datafiles using user managed Hot backup.

And on friday i have lost the 3 datafiles of the database unfortunately. How to restore and recover using the backups taken using 2 different methods.

Please see the below steps

>> Monday taking backup of 1st 2 datafiles using User managed Cold backup.
