UTL File problem

Posted on 16th Feb 2014 07:03 pm by admin

Hi
I have a file in certain path with the following permissions (The file is a dummy file without
any contents)--Zero byte file.

Permissions -rw-r--r--
I need to check if the file exist or not irrespective of file permissions,Is it possible.
If the file exist call a pl/sql and delete the file

else

Simply print a message.

I have written the following code but

I am getting the following error.. when file exist with above permisison, it will not call
the pl/sql
====================================
After opening utl file File name is :xx.txt
File exists xx.txt at /gpsescs1/custom/gl/inbound
Invalid operation because File does not exist-29283 ORA-29283: invalid file operation
====================================

If the file is present with rwxrwxrwx it completes normal by calliing the pl/sql

================
if the file is not present in the directory
it shows the following message

Invalid operation because File does not exist-29283 ORA-29283: invalid file operation
ORA-06512: at
"SYS.UTL_FILE", line 488
