Hi,

Do you have archive backup? If so u can apply archive and re-create.

Otherwise, incomplete recovery Embarassed

Without backup you can't do anything.

I have some few archives because there is no backup initiall and the archive location gets to 100% and shut everything stop, so i have to move some out to another location and zipped some inside the archive location ;this creates more space in archive location and and everything started working fine.
So i take backup of the archive to another location with delete input,so all those that were moved out to another location and those that were zipped inside the archive location were not backed up.I noticed this when i ran crosscheck archivelog all;

also a lot of datafiles are nolonger existing in the os level and no backup at all;
Tell me exactly what to do at this moment to open the database.This is a production database.

Thanks and regards for your quick response.

Startup mount, put the file in "offline drop" mode then you can open the database, drop the tablespace and recreate it and what was in it. Given its name I think (and hope) it is just recreate indexes.
