Oracle Error Message
PLS-00925: native compilation failed: Unable to create file (string string)
Reason for the Error
Native compilation of a PL/SQL program failed because a file could not be created. It is likely that the system parameter plsql_native_library_dir does not reference a writable, existing directory
Solution
Ensure that the system parameter plsql_native_library_dir references a directory which exists, and is writable.
