For all files you need to create from Oracle on the O/S
you need
either
- a directory listed in the utl_file_dir parameter
- a (symbolic) directory object
Utl_file_dir is for backwards compatibility only, but as you don't have directory objects, the parameter was interpreted as a hardcoded utl_file_dir directory.
To create directory objects issue
create directory logmnr_output as 'C:\oracle\product\10.2.0\db_1\';
grant read,write on logmnr_output to public;
For this solution you don't need to bounce the database.
You need to change the hardcoded directory name in logmnr_output
The other solution
alter system set utl_file_dir='C:\oracle\product\10.2.0\db_1\' scope=spfile;
and bounce the database
If you would have looked up the error message, you could easily have come up with this solution yourself.
