ORA-01284: file string cannot be opened

Expert Oracle Database Tips by Donald BurlesonSeptember 14, 2015

Question: I can getting this error when using utl_file and in LogMiner when I try to open a file on my server:

ORA-01284: file string cannot be opened

What is the exact cause of the ORA-01284 error and how to I make it so that Oracle can open this file?

Answer: This ORA-01284 error is caused when a files does not exist, the file name is too long (> 32 characters) or when the directory of file permissions do not allow the file to be opened.  Check that the file name is valid and that the file and directory node has at least 750 permissions for the owner and group.  The docs note this on the ORA-01284 error:

ORA-01284: file string cannot be opened

Cause: The file or directory may not exist or may be inaccessible. Pathname exceeds 256 characters.

Action: Ensure that the file and the directory exist and are accessible.

Also see PLS-00109: unknown exception name tips for trapping the ORA-01284 error.
