Use utl-file to operate file in Oracle

The below is about utl_file operation:

First, you should make a directory at the path that you wish:

[jeffreyxu@rat167 ~]$ mkdir test_dir

If you want anyone has the privileges read, write and execute, you can use the command to add these privileges to this directory.

[jeffreyxu@rat167 ~]$ chmod 777 test_dir 

Use sys account log in oracle, and the next commands are entered by sys

[jeffreyxu@rat167 ~]$ rlwrap sqlplus sys/111111@localhost:1522/xe as sysdba;
