Access to the following views requires purchase of a license for the diagnostics pack:

• V$ACTIVE_SESSION_HISTORY
• SYS.X$ASH (a fixed view)
• DBA_STREAMS_TP_PATH_BOTTLENECK
• DBA_STREAMS_TP_COMPONENT_STAT
• DBA_ADDM_% views
• DBA_ADVISOR_% views (if queried for ADVISOR_NAME='ADDM')
• DBA_HIST_% views (with a few exceptions)
• Most MGMT$% views

Access to these two views requires purchase of a license for the tuning pack, in addition to one for the diagnostics pack:

• V$SQL_MONITOR
• V$SQL_PLAN_MONITOR

Other restrictions apply to certain DBMS_% packages and SQL scripts.  For example, creation of any of the following types of reports requires purchase of a license for the diagnostics pack:

• AWR
• ASH
• ADDM

although it is important to note that you do not need to disable AWR snapshot generation in order to be in compliance.

Please consult the Oracle Database Licensing Information Guide for further details.

No licensing pack needs to be purchased in order to take advantage of Statspack.  However, you might wish to schedule Statspack snapshot collection, hourly, at thirty minutes past the hour, so as not to interfere with the collection of AWR snapshots, which occur at the top of each hour, by default.

You must use due diligence to avoid accessing Oracle-supplied views and packages, unless properly licensed. However, it is possible to advise the database instance on which packs have been licensed by setting the appropriate value for CONTROL_MANAGEMENT_PACK_ACCESS.
