I performed an fsck on a file system to try and recover some files.  The fsck was successful, no frags.  However I am trying to recover some db files that are in the lost+found folder.  I have been researching suggestions how to look and recover these files if at all possible.  Do you have any suggestions?  thanks

Explain more clearly what you're trying to accomplish.

You found some files in lost+found and are trying to figure out what to do with them?  Or you lost some files (how?) and are trying to find them?

DB files were lost after a process was to upload some data files by the dba. Received several ORA errors (see attached alert file) and files disappeared.  Ran fsck to see if the files would be recovered after any inconsistencies were fixed.  Fsck was successful 0% frags.  However files were recovered in lost+found which possibly are the db files that disappeared. Research how to view and possibly recover.  My question:  do you think it's worth the effort to go through those files or should we just do a restore from backup files.  I appreciate your assistance.

When machine is crash or file system interrupt it will store some files and folder in some binary format then we have to restore where you have requested.

Also is it safe to delete the files from the lost+found folder since it's taking up space?

It is very unlikely that the lost+found contains usable database files. Fsck is not a file recovery tool, it only creates a consistent file system.  Any orphaned file fragments that are found are stored in l+f.

So recovery from backup is necessary and you can delete the files in L+F.
