In case you haven't found the answer yet ...

If you _know_ the external procedure is being executed, then there are two possible causes of the problem.

1. The oracle account on your server does not have read/write access to the directory that you are creating or deleting the file from. As far as I know, external procedures run under the oracle account as far as the server operating system is concerned.
2. When you compile the C library, make sure you have correctly specified the Oracle includes. For example:

gcc -I/oracle/product/8.1.5/rdbms/demo
-I/oracle/product/8.1.5/network/public etc.

Make sure the above paths are correct. These Oracle libraries include things that allow the server oracle account to write to operating system files.

Let me know what happens.
