Hi Zerandib,
In order to restore online backups, you need all datafiles plus archive logs generated during your online backup window. There is no other way to perform a consistent recovery from online backup without archives.
The only way to perform a PIT (Point in time recovery) is from a incomplete recovery. One example to do this is restoring all datafiles, plus archivelogs, and execute the "RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL" statement. Incomplete recovery will not work anymore if you firstly try to perform a complete recovery instead (so you might get the "ORA-01195" either from doing this, or from a missing archivelog during your recovery).
Personally I would try to do recover one more time from scratch. If it fails again due missing archives, There is a way to "force" opening your database even with missing archives, setting the "_ALLOW_RESETLOGS_CORRUPTION=TRUE" parameter in your init<sid>.ora file. This will allow to open database without performing a consistency check, but attention - Oracle does not guarantee your database consistency after setting this parameter. Check Oracle alert file after doing this to check the side effects. I was able to recover a database once using this param because only the UNDO tablespace was corrupted. After recreating UNDO tablespace, the issue was cleared.
Hope it helps.
