Let me quote... "If you get audited by Oracle you may find yourself paying a fine for using all of the OEM grid control features without purchasing the $6,000 Oracle diagnostic and tuning packs.

Starting in Oracle 10g, using the built-in ADDM or querying the Active Session History (ASH) or Automatic Workload Repository (AWR) tables requires an extra cost license. Many shop accidently query these restricted tables and the activity is logged within Oracle hidden auditing facility, to be revealed upon an audit by Oracle Corporation." (1)
