You may use user_libraries or all_libraries. I tested the above query on my Windows XP running Oracle XE (connected as sys as sysdba), here is what I got: <i>C:/ADE/aime_051006/oracle/rdbms/</i>. The funny thing is, I do not seem to find this directory at all on my C drive ?! Note that you may not have access to dba_libraries. You may use user_libraries or all_libraries.
