How to read or write file from mapped drive(remote location) by file_ult_dir in oracle 12c. For example my database server is three network drives (C:\, D:\, Z:\). In that two are local drive and one mapped drive by another location. When I tried to read and write any thing in local drive (C,D), It works but if I try to do same task on Z drive. It does not work. It gives error (ORA-29283: invalid file operation). I have done all the things means given grant for db user or make public also, still same. Please help me.
Thanks
