missing datafile on STANDBY DATABASE.

Hello list,

We are maintaining the standby database to our one of important database. On 5th August, a datafile has been added to primary database, unfortunately, there was no sufficient space on standby server. MRP background process has died and no archive logs were applied until now. I try to rename the datafile, create datafile, but, couldn't succeeded. Opened a TAR with oracle and they said that rebuild standby. I couldn't find the 'UNNAMED00266' file at OS leve. But, the entry is there in v$datafile.
I have even cheked all my backups from 5th August, finding a luck to have the file in backup, if someone deleted the file. But, not luck. Is there any way that we can resolve this issue? I have all the archived log since that point.

Thanks,
