We're getting the following error in an SQL procedure on Ubuntu. The same procedure is executing properly on Windows. The goal of the procedure is to import a .csv file into an external oracle table.
The Oracle error:
ORA-29283: invalid file operation ORA-06512: at "SYS.UTL_FILE", line 536 ORA-29283: invalid file operation
This SO question might have been a solution, but even after giving proper permissions chmod 777 (which solved the issue in that case) to the files concerned we are facing the same error.
ORA-29283: invalid file operation ORA-06512: at "SYS.UTL_FILE", line 536
The concerned portion of the procedure is :

The line on which the error is occurring is:
file_handle := UTL_FILE.FOPEN('EXP_DATA',i.file_name,'R');
The permissions given to the file is as follows:
-rwxrwxrwx 1 rama rama 240 Feb 26 11:24 exp_41_02_2016.csv`
How to trace the problem which is causing this issue? Please let me know if you want any other information?
